Spring's Winged Thing Continues: Bogong Weather Anomaly + Butterflies

Since our last Issue, and celebrating the return of the bogong moth, food for mountain pygmy possums and a sign of Spring that has recurred for thousands of years, others have been celebrating too.

An estimated 4 billion Bogong moths are currently moving across New South Wales toward the cool alpine caves of the Snowy Mountains, pushed off course by strong westerly and northerly winds.

However, these massive swarms of migrating Bogong moths are creating false "rain" blobs on Bureau of Meteorology (BOM) weather radars across Sydney, Newcastle, and Wollongong. You may have noticed the radar showing widespread coverage but no mm of rainfall recorded - that's because this cloud is a cloud of Bogongs.

As the sun sets, millions of Bogong moths take flight from their daytime resting spots. The dense clouds of flying insects reflect the weather radar beams back to the station, showing up as 'light to moderate' rain showers on clear, cloudless nights. 

The radar returns magically vanish around sunrise when the moths settle down for the day.

Scientists are noting this massive influx is a hopeful sign of recovery for the species, which suffered a 99.5% population crash during the 2017–2019 drought.

The Bogong moths are the main food source for the Mountain Pygmy Possum. 

Zoos Victoria states:

Mountain Pygmy-possums were thought to be extinct until they were rediscovered at Mt Hotham in 1966. There are fewer than 2,000 endangered Mountain Pygmy-possums left in the wild. The possum is Australia’s only hibernating marsupial; it hibernates for up to seven months under the snow. 

There are three populations of Mountain Pygmy-possums. They live in the alpine and subalpine rocks and boulders found in the Bogong High Plains, at Mount Buller in Victoria and Mount Kosciusko in New South Wales (NSW states it has two population areas - see below). 

Climate change, the loss of habitat and predators, mainly feral cats and foxes, are all severe threats to the Mountain Pygmy-possum.  

An emerging threat is the reduction in the possum's key food source over Spring, the Bogong Moth. This is currently a particular focus within the Mountain Pygmy-possum Recovery Team. 

Each Spring, Mountain Pygmy-possums wake up from their annual hibernation, hungry for nutritious Bogong Moths to eat. 

Bogong Moths usually fly to the possums' home in the billions, but their numbers have significantly decreased over recent years. This now means that there may not be enough food for these tiny possums to raise their babies. In December 2021, Bogong Moths were added to the IUCN Endangered Species list. 

We need Australia's help finding these moths and guiding them to the possums! 

It's simple: If you see a Bogong Moth, take a photo and upload it to Moth Tracker, even if you're not sure it's a Bogong Moth. This will help scientists better understand if the moths will make it to the mountains each year.  

As well as drought and pesticide use, bright lights from towns and cities are thought to lure and trap the moths along their migration route. 

The plan for fighting extinction

Zoos Victoria became involved in the Mountain Pygmy-possum Recovery Program in 2006. Healesville Sanctuary currently holds a large research and breeding population. We also assist with surveying wild populations, helping with habitat connectivity and revegetation, and developing new nutritious food sources like Bogong Bikkies. 

Zoos Victoria also leads Moth Tracker, a citizen science project for recording Bogong Moths sightings.

The NSW Department of Environment tells us Mountain Pygmy-Possums are listed as endangered by extinction in New South Wales.

Also:

Mountain Pygmy-possum adults average 40 grams but vary from 30 grams in spring up to 80 grams in autumn when they fatten for winter hibernation. Of the total length of 250 mm, over half is tail. The fur is dense and fine, grey-brown above and creamy to bright fawn under the body. The nose is pink and there are dark shadows around the eyes. The tail, which can be coiled, is furred for 2 cm at its base, then greyish-pink, with short, sparse hairs. In its mountain habitat, this species could only be mistaken for a House Mouse, but its larger size, part furry and coiled tail, 5 (not 4) front toes, and joined (syndactyl) second and third back toes should be enough to distinguish it.

  • Scientific name: Burramys parvus
  • Conservation status in NSW: Endangered
  • Commonwealth status: Endangered
  • Gazetted date: 16 Mar 2001
  • Profile last updated: 27 Aug 2026

Distribution

The Mountain Pygmy-possum lives only in alpine and subalpine areas on the highest mountains of Victoria and NSW. In NSW there are two populations. The Southern population 30 km by 8 km area of Kosciuszko National Park between Thredbo and Kerries Ridge, where it occupies less than four square kilometres of habitat. In the North the population occurs at lower elevations from the Cabramurra area east to Happy Jacks.  

Habitat and ecology

Lives on the ground in rocky areas where boulders have accumulated below mountain peaks; frequently associated with alpine heathland shrubs dominated by the Mountain Plum-pine (Podocarpus lawencei).

Survives Winter by fattening in late Summer and Autumn and hibernating for up to seven months, from Autumn until the snow melts in Spring.

Seventy percent of the diet is invertebrates such as the migratory Bogong Moth, caterpillars, beetles, spiders and millipedes; the remainder comprises fruits and seeds from species such as the Mountain Plum Pine and Snow Beard-heath.

One litter of four young are produced in Spring; young are independent by late Summer; breeds when one year old; average longevity is two to three years but females may live up to thirteen years and males five years.

Daily movements between habitat patches can be up to 1 km for females and 3 km for males; males and young animals disperse in autumn.

The mountain pygmy-possum experiences a long period of hibernation (torpor). At higher elevations it is dependent on winter snow providing insulation for its survival.

Butterflies

Of course, other moths and butterflies are moving across and through the landscape at present too - many of them feasting on nectar from all the plants currently in full Spring bloom. In the south end of Pittwater Joe Mills took this great specimen:

Warriewood Wetlands - Varied Sword-grass Brown Butterfly (Tisiphone abeona) on Blackberry Flowers Photos: Joe Mills

Tisiphone abeona, the swordgrass brown, is a nymphalid butterfly. It is endemic to Australia. The wings of the adult are brown and have a wingspan of about 60 mm. The larvae feed on Gahnia species.

Museums Victoria states:

General Description

Adult: Above: dark brown, forewing with orange bands and two blue-centred black eyespots; hind wing with a large blue-centred black eyespot ringed orange. Beneath: Brown, forewing as above but paler; hindwing, markings as above but eyespots more prominent in a narrow cream band. Wingspan 54-59 mm. Egg: Green, almost spherical, slightly roughened surface. 1.5 mm. Larva: Green with forked posterior projection. 62 mm. Pupa: Green, and smooth, yellow ridge along forewing. 18 mm.

Biology

Varied Sword-grass Browns are slow, graceful flyers, flying within a metre to the ground and close to their food plants. Adults will frequently land on Saw-sedges to bask in the sun with their wings open. Eggs are generally laid singly on the underside of young leaves. Larvae generally feed on Red-fruited Saw-sedge (Gahnia sieberiana) in Victoria but other Gahnia species have also been recorded as hosts outside Victoria. Larvae shelter near the base of the leaf during the day and ascend to feed at night, creating characteristic V-notches in the leaf. Pupation occurs deep within the plant, the pupa attached to the underside of the leaf and suspended head downwards. In Victoria there is one generation a year at high altitudes, but two generations in warmer areas.

Distribution

Six subspecies are recognised ranging from coastal South East Queensland to the south east corner of South Australia. One subspecies occurs in Victoria from Alpine areas, in the outer eastern suburbs of Melbourne, the Dandenong ranges and wet forest areas of the Grampians, Wilson's promontory and East Gippsland.

Habitat

Common in a range of habitats from alpine to suburban, including wet forests.

One we saw this week in the garden is a Papilio demoleus, a widespread swallowtail butterfly. The butterfly is also known as the lemon butterfly and chequered swallowtail, which refer to their host plants, usually citrus species such as the cultivated lime. 

Papilio demoleus at Careel Bay, Sunday October 11 2026. Photos: A J Guesdon

Wikipedia shares:

Unlike most swallowtail butterflies, it does not have a prominent tail. When the adult stage is taken into consideration, the lime swallowtail is the shortest-lived butterfly, with male adults dying after four days and females after a week. The butterfly is native to Asia and Australia.

The butterfly is tailless and has a wingspan 80–100 mm.  Above, the background colour is black. A broad, irregular yellow band is found on the wings above, which is broken in the case of the forewing. Besides this, the butterfly has a large number of irregular spots on the wing. The upper hindwing has a red tornal spot with blue edging around it.

Detailed description as given by Charles Thomas Bingham in 1905:

"Upper side of wings has the ground colour black. The fore wing has the base below cell and basal half of latter so irrorated with yellow scales as to form more or less complete transverse dotted lines, two outwardly oblique yellow spots in cell and a curved spot at its upper apex; a spot at base and another beyond it in interspace 8; a discal transverse series of cream-yellow spots irregular in arrangement and size extends from interspace la to 8; the series interrupted in interspace 5 and the spot in interspace 7 double; this is followed by a sinuous postdiscal series of spots and an admarginal terminal series of smaller spots. In many specimens between the discal and postdiscal series the black ground-colour is irrorated with yellowish scales. Hind wing: base and an edging that decreases in width along the dorsal margin irrorated with yellow scales; followed by a broad medial yellow irregular band, a sinuous postdiscal series of outwardly emarginate yellow spots and a terminal series of smaller similarly coloured spots as on the fore wing. The inner margin of the medial band is curved inwards, the outer margin is very irregular and uneven; in the cell the band does not reach the apex, but beyond the cell there are one or more cream-yellow spots, and the black groundcolour is irrorated with yellowish scales; finally at the tornal angle there is an oval ochraceous-red spot emarginate on its inner side in the female and in both sexes surmounted by a blue lunule; while in interspace 7 between the medial band and the postdiscal spot there is a large ocellus-like spot of the black ground-colour more or less irrorated with blue scales."

"The underside has the ground-colour similar, the cream-coloured markings paler and conspicuously larger. The markings differ from those on the upperside in that the forewing has the basal half of cell and base of wing below it with cream-coloured streaks that coalesce at base; irregular ochraceous spots in interspaces 5 to 8 and the discal series of spots complete not interrupted in interspace 5. On the underside of the hind wing, the black at base of wing and along the dorsal margin centred largely with pale cream-colour; the ocellus in interspace 7, the apex of the cell and the black groundcolour between the medial band and postdiscal markings in interspaces 2–6 centred with ochraceous, margined with blue.

Antennae dark reddish brown, touched with ochraceous on the innerside towards the club; head, thorax and abdomen dusky black, the head and thorax anteriorly streaked with cream-yellow: beneath: the palpi, thorax and abdomen cream-yellow with lateral longitudinal black lines on the last."

This butterfly is an avid mud-puddler and visitor of flowers. It basks with its wings held wide open on tufts of grass and herbs, and generally keeps within a metre of the ground, even on cloudy days. It relies on its quick flight for escape. It has a number of modes of flight. In the cool of the morning, the flight is slow considering that it is an edible and unprotected swallowtail. As the day progresses, it flies fast, straight, and low. In the hotter part of the day, it may be found settling on damp patches, where it will remain motionless, except for an occasional flutter of wings, if not disturbed. It is also a frequent visitor of flowers in gardens, where it shows a preference for flowers of smaller herbs rather than larger plants such as the ubiquitous Lantana with its plentiful blooms. It can be found swarming in the groves of its food plants.

The typical time for one generation of P. demoleus to mature in the field ranges from 26 to 59 days. In cold climates, the lime butterfly is known to pass the Winter as pupae. Typically, the butterfly undergoes five instars as a caterpillar.

The female butterfly goes from plant to plant, laying a single egg at a time on top of a leaf, which it holds onto with its legs, and flies off as soon as the egg is laid. The egg is round, light yellowish in colour, flattened at the base, smooth-surfaced, and about 1.5 mm in height. Fertile eggs develop a small red mark at the apex.

Captive breeding of P. demoleus in Riyadh has revealed these data about the lifespan of various stages at that locality:

  • Number of generations per year: 8
  • Duration of egg stage: 3.1 to 6.1 days
  • Duration of larva stage: 12.9 and 22.7 days
  • Duration of pupa stage: 8.0 to 22.4 days
  • Duration of adult stage: 4 to 6 days with average of 5.1 days

In Australia and Papua New Guinea, the butterfly also feeds on host plants of family Fabaceae. They have been observed on:

Many species of Cullen: Cullen australasicum, C. badocanum, C. balsamicum, C. cinereum, C. patens (spreading scurf-pea, native verbine), C. pustulatum, and C. tenax (tough scurf-pea, emu-foot, emu grass), and C. leucanthum. Psoralea pinnata (fountain bush).

By Pittwater Pathways: 4 Oct 2026

Xanthorrhoea spp. flower spike tip 4.8m from ground. In flower for about two weeks, visited constantly by birds and most recently by bogong moths on 4 October 2026.

It was planted 27 years ago and produced its first spear 2 years ago but this second is much higher. It is a beautiful plant, almost snowy white in blossom and reminiscent of Arthur's Excalibur perhaps.

From bogong moths to Christmas beetles – how to slow down and spot more insects

Millions of people worldwide watched on as the Sydney Olympics came to a close in 2000. Meanwhile, thousands of bogong moths (Agrotis infusa) were airborne, making their annual migration to the Australian Alps.

These bogong moths swarmed in such large numbers that the rain radars showed a storm approaching Sydney. The bright lights of Stadium Australia, where the closing ceremony was unfolding, had lured them in.

As an entomologist, I’m fascinated by insects. This year, the bogong moth population has exploded along Australia’s east coast, with people discovering these insects in every nook and cranny of their homes.

The current resurgence offers scientists valuable information about the health and abundance of the bogong moth population. But they aren’t the only insects worth watching.

Bogongs bouncing back

Bogong moths are small, brown insects that typically fly at night. Each year, they embark on a magical migration, travelling up to 1,000 kilometres across Australia.

By following the stars, they are able to navigate to the cool caves of the Snowy Mountains in southern New South Wales, where they shelter during the sweltering summer. These moths then return to inland Australia to mate, lay eggs and repeat this migratory cycle.

In recent decades, the bogong moth population has dramatically declined. Numbers fell by 99% between 2017 and 2019 alone. Like many other insects, bogong moths face multiple pressures including habitat destruction, drought and climate change. Light pollution may also hamper their ability to navigate during their mammoth migrations.

But this year, bogong moths have reappeared in remarkable numbers, particularly on the east coast of Australia. Two years of high rainfall have likely boosted the population by creating ideal breeding and feeding conditions. Strong winds may have also knocked the moths off their course, causing them to congregate in and around Sydney.

Many of us, myself included, have never witnessed bogong moths gather in such numbers. This means the public maybe be completely unaware of their decline, a concept known as “shifting baseline syndrome”. This is the idea that what younger generations understand to be a healthy natural environment is based on their own observations.

For example, a young Australian may think seeing very few bogong moths is “normal”. But an older Sydneysider, particularly if they were tuned into the 2000 Olympics, would remember when bogong moths were everywhere.

This matters for conservation. Knowing if an insect is thriving, stable or in decline can shape how much younger generations care about its survival. Once they understand these trends, we can teach them to observe and appreciate these creatures in everyday life.

Other insects worth watching

Bogong moths are hard to miss, particularly in such vast swarms. However, many of our rare and threatened insects have similarly had a resurgence, even from the brink of extinction. And ordinary people have helped rediscover them.

Citizen scientists have collected vital data about Christmas beetles (Anoplognathus). Across eastern Australia, these vibrant-hued critters used to emerge in their millions around December, just in time for Christmas. Tragically, Christmas beetles have become rarer in recent decades, possibly because of habitat destruction. Australia has no formal Christmas beetle monitoring program, so citizen scientists are helping researchers monitor the health of our surviving Christmas beetle populations.

Citizen science has also been crucial to the discovery of new stick insect species and even an unknown type of spider, found by someone appreciating the wildlife on their bin.

Stop – and spot more insects

Here are some tips to help you, your child or your science-loving friend pay more attention to the world of insects.

  • if you stumble across a bogong moth, take a moment to marvel, rather than simply letting them outside or killing them

  • listen out for cicadas, which typically start buzzing in spring

  • stare at some flowers, noticing any bees or insects hovering around them

  • look for iridescent Christmas beetles, which usually emerge from the soil in late spring.

You can also help monitor insect populations by taking photos of any insects you spot. If you see any bogong moths, you can upload them to Moth Tracker or iNaturalist. These online platforms help scientists monitor their population and track their migrations.

To make people care about our insects, particularly our most rare and vulnerable species, we can encourage them to get out in nature. Spring is the perfect time to do just that.The Conversation

Celebrate the Diversity of Pollinators: Art + Photography Comp. for Students

Australian Pollinator Week runs from 7–15 November and celebrates Australia’s diverse pollinators and highlights the importance of engaging young people in learning about pollinators. Schools are encouraged to celebrate and support pollinator health.

Australian Pollinator Week was founded by Dr Megan Halcroft, of Bees Business, in November 2015. It followed on from a community project called “Bee Aware of Your Native Bees”, which was funded by Western Sydney University and the Environmental Trust.

Communities in the northern hemisphere have been celebrating the importance of pollinators since June 2007, however, the seasonal differences in the southern hemisphere has restricted bilateral celebrations.

Australian Pollinator Week acknowledges our important and unique insect pollinators during Australia’s southern Spring (November). It is a designated week when communities, businesses and organisations can come together to raise awareness of the importance of pollinators and support their needs.

Through group activities, community members can learn together as they help to support pollinators. By engaging communities in schools, retirement villages, art groups, gardening clubs, community gardens, local council areas, Landcare groups and neighbourhoods we can increase awareness and act on our increased knowledge.

School Pollinator Art Competition

The School Pollinator Art Competition invites students across Australia to celebrate pollinators through art.

Students can submit original artworks in any medium, including drawing, painting, digital, collage or mixed media. Prizes will be awarded for the best artwork inspired by pollinators.

Draft NSW coastal management manual: Have your say

The Department of Climate Change, Energy, the Environment and Water is seeking feedback on the draft NSW coastal management manual.

Consultation period: 12th October 2026 - 30th October 2026

What’s this about?

The NSW Government is seeking feedback on a draft NSW coastal management manual. The current manual was published in 2018 and provides the requirements and guidance used to prepare, certify, implement and review coastal management programs across New South Wales. The draft manual responds to recommendations from the NSW Audit Office's Coastal management performance audit (2025) and feedback from councils, public authorities and coastal practitioners.

The proposed changes aim to:

  • make the manual easier to use
  • provide clearer requirements and practical guidance
  • improve the processes for preparing and certifying coastal management programs. 

The draft manual does not amend the Coastal Management Act 2016 or fundamentally change the statutory process for preparing and certifying coastal management programs. Existing certified programs will remain valid.

Following consultation, we will review the feedback and use it to finalise the draft manual. The updated manual will then be considered by the Minister for the Environment. If approved, once published in the NSW Government Gazette, the updated manual will replace the current manual and commence in late 2026.

Mandatory requirements and guidance for a coastal management program

The draft manual sets out mandatory requirements and supporting guidance for preparing, adopting, implementing, reviewing and amending coastal management programs under the Coastal Management Act 2016.

Draft Document cover: for ID when downloading

Proposed changes to the NSW coastal management manual consultation summary (PDF 1.59 MB / Pages 10)

This document summarises the main proposed changes and explains how they respond to recommendations from the NSW Audit Office and feedback from councils, government agencies and coastal practitioners. 

The proposed changes aim to make the manual easier to use, provide clearer requirements and practical guidance, and improve the processes for preparing and certifying coastal management programs. The draft manual also supports a more proportionate and risk-based approach to coastal management planning, stronger implementation and review, and improved recognition of Aboriginal cultural values, knowledge and participation.

We are particularly interested in whether the draft manual:

  • clearly identifies mandatory requirements
  • provides practical guidance
  • improves coastal management program preparation and certification
  • supports a proportionate and risk-based approach
  • provides clearer expectations for implementation and review
  • is easier to navigate and use than the current manual
  • allows for a simple transition for existing and in-train CMPs
  • could create any unintended practical consequences.

We invite councils, coastal practitioners, government agencies, community organisations and interested members of the public to review the draft manual and provide feedback. Your feedback will help inform the final manual before it is considered by the Minister for the Environment.

Draft Koala Conservation Strategy: Have Your Say

The Department of Climate Change, Energy, the Environment and Water is seeking feedback on the Draft Koala Conservation Strategy.

Consultation period: 12th October 2026 - 9th November 2026

The Draft Koala Conservation Strategy:

  • identifies key koala populations
  • outlines a toolbox of conservation actions that can be applied to address key threats to koalas.

What is changing?

The draft strategy adopts a landscape-scale approach to koala conservation. This approach recognises that, to protect koalas, we must protect and restore the ecosystems they depend on.

The strategy will be delivered through the Saving our Species framework, ensuring koala conservation is integrated with other threatened species conservation efforts across the state.

The strategy will be delivered through the Saving our Species framework, integrating koala conservation with other threatened species conservation efforts across NSW.

Your feedback will help shape the final strategy to ensure it is practical, effective and informed by local knowledge.

Namoi long-term water plan review: Have Your Say

The Department of Climate Change, Energy, the Environment and Water is seeking feedback on the draft second edition of the Namoi long-term water plan.

Consultation period: 9th October 2026 - 30th October 2026

What’s this about?

The Department of Climate Change, Energy, the Environment and Water is reviewing and updating the Namoi long-term water plan. We are seeking feedback from communities, stakeholders and Aboriginal peoples.

Long-term water plans guide how environmental water is managed across 9 NSW Murray-Darling Basin catchments. 

The plans set:

  • long-term objectives
  • targets
  • water requirements.

These support the health of:

  • rivers
  • wetlands
  • floodplains
  • and the ecosystems and communities that depend on them.

The Murray-Darling Basin Plan requires these plans to be reviewed every 5 years.

Reviewing the Namoi long-term water plan ensures it reflects the latest scientific, climate and environmental knowledge, as well as stakeholder feedback.

The review includes stronger engagement with Aboriginal communities and consideration of Aboriginal knowledge, values and objectives.

The department will consider all submissions received during consultation. Your feedback will:

  • help inform the final plan
  • guide the management of environmental water in the Namoi catchment over the next 20 years.

Namoi Long-Term Water Plan Documents Review: The draft plan

The proposed second edition of the Namoi LTWP includes:

  • updated information and analysis
  • refined objectives and targets
  • improved understanding of climate change risks
  • updates to low-flow environmental water requirements
  • strengthened recognition of Aboriginal values, knowledge and aspirations.

See a summary of the proposed changes to the plan.

Summary of the proposed changes to the plan.

Background

As part of a 5-year review, the 9 long-term water plans (LTWPs) for NSW inland catchments within the Murray-Darling Basin are being updated to reflect the latest policy, science and stakeholder input. This second edition also responds to the 2025 update of the Murray-Darling Basin Authority’s (MDBA) Basin-wide environmental watering strategy (BWS).  

Key changes and improvements to LTWPs include: 

  • strengthened First Nations engagement and content
  • refined ecological objectives and targets
  • refined environmental water requirements (EWRs) for low flows and new or modified EWRs in some areas
  • enhanced consideration of climate change 
  • strengthened risk management and investment alignment
  • enhanced socio-economic considerations.

Strengthened First Nations engagement and content

Significant progress has been made in working with Aboriginal Traditional Owners and groups to build relationships and inform how Aboriginal people wish to be represented in updated LTWPs. Targeted engagement has identified additional cultural values, objectives and outcomes requiring careful integration into plan content.

Building on the 2025 BWS, this remains a priority for NSW to ensure LTWPs appropriately reflect cultural water values and support enduring relationships and outcomes for Aboriginal people.

Refined ecological objectives and targets

Ecological objectives and targets have been refined to improve alignment with monitoring and evaluation frameworks, enhance measurability, and support clearer tracking of environmental outcomes. 

Updated environmental water requirements

Second edition LTWPs include refined cease‑to‑flow, very low flows and baseflow EWRs to improve clarity and support assessment. These changes provide clearer definition of frequency, duration and maximum inter-event requirements.

For cease-to-flow EWRs, duration and frequency requirements have been updated at all locations based on improved analysis of cease-to-flow events in historical and modelled flow records. 

In the Namoi LTWP, additional EWR updates include revised bank full and overbank flow thresholds for the Keepit to Boggabri planning unit (Namoi River at Gunnedah gauge). At this location, bank full and overbank EWR flow rates have been reduced to better reflect river channel characteristics and observed flow and inundation patterns. 

A new guidance section for using EWRs is also included in the updated LTWP.

Enhanced climate change considerations

Climate change has been a key focus of the review, with sections strengthened through:

  • updated projections for changes to temperature, rainfall and streamflow
  • improved analysis to illustrate the sensitivity of selected EWRs to a range of water availability scenarios under climate change.

These updates enable a more robust and in-depth assessment of future flow scenarios, climate risks and potential management responses, strengthening the overall evidence base.

Strengthened risk management and investment alignment

Risks and constraints to LTWP objectives and EWRs, and their associated mitigation strategies, have been updated and are supported by revised investment opportunities. These revisions will strengthen implementation by providing better clarity on priority actions, potential partner agency roles, and opportunities to mitigate risks and enhance environmental and cultural outcomes.

Enhanced socio-economic considerations

Socio-economic considerations have been integrated into the LTWPs, in alignment with the 2025 BWS. These considerations recognise the contribution of environmental watering to regional communities and economies.

Be plover lovers: RSPCA NSW calls for kindness during nesting season

RSPCA NSW is calling on the community to be plover lovers this nesting season, as interactions between people and protective plover parents increase. 

Sadly, since the start of nesting season, RSPCA NSW has received several reports of young people disturbing or harassing plovers in their local areas. 

Plovers, also known as masked lapwings, are native birds and protected under the Biodiversity Conservation Act. 

They are commonly found in large grassy areas, where they usually lay their eggs on the ground in open spaces to better spot potential predators. 

Plover eggs take about 28 days to hatch and while chicks become remarkably independent soon after hatching, their parents remain highly protective of their nests and young. 

This protective behaviour can sometimes include swooping at people who come too close, but it is generally a warning display, and actual physical contact is rare. 

Although swooping can be unsettling, it is important to remember that plover parents are simply trying to protect their chicks and should be treated with patience and respect. 

FUN FACT: Along with occasional swooping and loud calls, plover parents may also pretend to have a broken wing to draw predators away from their nest or chicks. 

RSPCA Australia Chief Science Officer Dr Suzie Fowler stressed that the right response to nesting birds like plovers is crucial.  

“Although these swoops can be alarming, they are typically brief and targeted, rather than random acts of aggression,” Dr Fowler said. “Approaching nests or attempting to harm an animal can increase future risk of swooping and is never an appropriate response.” 

If you come across a nesting plover, the best thing you can do is keep your distance, take an alternative route where possible, and allow the family the short period of protection they need until the chicks are safely on their way. 

Plovers are devoted parents doing their best to keep their chicks safe at a vulnerable stage of life and deserve the love of their local communities. 

If you have animal welfare concerns, please call RSPCA NSW to investigate on 1300 CRUELTY (1300 278 3589) or 9770 7555.

Federal Coalition plan to scrap Scope 3 emissions reporting

On Wednesday October 14 2026 the Federal Coalition announced 'a future Coalition Government will scrap climate reporting red tape which is making life harder for Australian businesses.'

'The Liberals and Nationals will today introduce the Treasury Laws Amendment (Scrapping Scope 3) Bill 2026 to the Senate to mandatory Scope 3 emissions reporting and remove Group 3 entities from mandatory sustainability reporting, cutting unnecessary compliance costs for Australian businesses.' a released statement said

Scope 3 emissions are all indirect greenhouse gas emissions that occur in a company’s upstream and downstream value chain, outside of its direct operations (Scope 1) and purchased energy (Scope 2).

Scope 3 emissions typically account for 70% to 90% (and up to 95% in certain sectors like food or capital goods) of a company's total carbon footprint, according to CDP. The Greenhouse Gas Protocol defines 15 categories of scope 3 emissions spanning everything from purchased goods, business travel, to how customers use and dispose of your products (e.g: waste disposal for plastic packaging).

A Group 3 entity is the third and final cohort under Australia's mandatory climate-related financial reporting regime, governed by the Corporations Act 2001.

An organisation is classified as a Group 3 entity if it is required to prepare and lodge financial reports under Chapter 2M of the Corporations Act 2001 and meets at least two of the following three thresholds at the end of the financial year (including controlled entities):

  • Consolidated Revenue: $50 million or more
  • Consolidated Gross Assets: $25 million or more
  • employees numbering 100 or more

Key Requirements and Rules for Group 3:

  • Materiality Exemption: Unlike Groups 1 and 2, a Group 3 entity is exempt from preparing a full sustainability report if it concludes it has no material climate-related financial risks or opportunities.
  • Statement of No Material Risk: If claiming the exemption, the entity must formally disclose a statement declaring that it has no material climate risks or opportunities, along with the detailed reasoning and governance process behind that conclusion. This statement is subject to formal review and forms part of the directors' declaration.
  • Core Disclosures: For Group 3 entities that do identify material climate risks or opportunities, reports must cover governance, strategy, risk management, and metrics and targets under AASB S2, lodged alongside the standard financial report with the Australian Securities and Investments Commission

The Coalitions statements goes on to say:

'Labor’s own Treasury estimated Scope 3 emissions modelling alone could cost around $245,000 per entity in the first year, and more than $160,000 annually thereafter.'

'From July 2027, Group 3 entities will enter the climate reporting regime and face estimated costs of up to $70,000 in the first year alone.

Australian businesses are already dealing with high costs, high taxes, high energy prices, and too much red tape. They don’t need another layer of expensive paperwork.

Leader of the Opposition Angus Taylor stated 'it is absurd to force Australian businesses to report on emissions they cannot control, using data they often cannot access, at a cost running into hundreds of thousands of dollars.'

“Businesses should be focused on employing Australians, investing and growing, not spending a fortune trying to calculate emissions across their supply chains.

“Anthony Albanese should follow the Coalition’s lead and scrap his latest business burden tax, giving businesses certainty before it comes into effect next year.

“This builds on the Coalition’s announcement to ensure no Australian government can use Scope 3 emissions from Australian exports being used overseas to delay or block approval of a resources project.”

Leader of The Nationals Matt Canavan said the High Court's decision has already overturned the approval for the Mount Pleasant expansion, putting future investment and employment under a cloud of uncertainty.

“Australian mining projects should not be held hostage to emissions from coal burned in Japan, Korea or Chinese power stations,” Senator Canavan said.

“If Australia cannot export coal, our partners will simply look elsewhere, while thousands of jobs will be lost as a result and our prosperity as a nation suffers another hit.”

Deputy Leader of the Opposition Jane Hume said Australia cannot regulate its way to prosperity.

“These reporting obligations don’t stop with the large corporations, they cascade through supply chains, forcing smaller businesses to provide complex emissions information to their larger customers.

“This all comes at a cost. It is money that could be spent employing Australians, purchasing equipment or expanding operations.

“The Coalition has a plan to cut red tape, lift productivity and make life easier for Australian businesses, because our businesses should be driving Australia’s prosperity, not being held back by Labor’s bureaucracy.”

Shadow Treasurer Tim Wilson said the Albanese Government is engaging in trickle down regulation from big onto small business.

“If a local motel wants to provide rooms to a corporate, it shouldn’t have to hand over a scope 3 emissions report.

“Canberra is designing laws as if every corner store, motel and home business has an HR department, a legal team and a compliance division sitting behind it. They don't. They just want to get on with running their business and supporting their families."

In November 2025 the Coalition formally endorsed its policy on climate and energy that dropped its commitment to net zero and gives priority to supporting more fossil fuels, such as gas and coal, being produced.

That plan includes running existing coal-fired power stations harder and longer, protecting coal and gas projects from being blocked by overseas emissions challenges (such as Scope 3 rules), and subsidising coal, gas, and nuclear.

The Treasury Laws Amendment (Scrapping Scope 3) Bill 2026 would mean companies will have less obligation to disclose their full climate footprint to investors and the public, making it harder for people to understand which businesses are actually reducing emissions versus just the parts they directly control. This would impact how potential investors assess climate risk and how consumers make purchasing choices.

Federal Coalition Pledges to stop Australians challenging Projects that increase Climate Change Impacts in Australian courts

Days prior to this announcement, on October 10, the Coalition announced it 'will stop Australia’s resources industry being ruined by activists, who are doing everything possible to shut down Australian mining and prosperity.'

'The Liberals and Nationals will be introducing the Australian Resources Exports and Jobs Protection Bill, ensuring coal, gas and other resource projects cannot be stopped on the basis of emissions occurring overseas.' a released statement said

'It comes after the High Court dismissed MACH Energy’s appeal to expand the New South Wales Mount Pleasant coal mine, on the basis that authorities failed to properly consider the impact of emissions by its customers overseas.'

''Leader of the Opposition Angus Taylor said the Coalition would introduce legislation to stop thousands of mining jobs and Australia’s standing as a reliable energy exporter being put at risk.''

“A future Coalition Government will ensure no Australian government can use Scope 3 emissions from Australian exports being used overseas to delay or block approval of a resources project,” Mr Taylor said.

“It is madness that local planning authorities must now consider the climate impacts of resources used in other countries before approving a mine in New South Wales.

“If Australia cannot export our resources, our partners will simply look elsewhere, while thousands of jobs will be lost as a result and our prosperity as a nation suffers another hit.

“We will introduce new legislation so that state governments cannot refuse projects on the basis of Scope 3 emissions occurring overseas as a reason to assess, block, delay, restrict or impose new conditions on federally approved projects.”

'The Bill will establish a clear national principle that Australian resource projects should be assessed on the environmental impacts of producing resources in Australia, not on emissions generated when Australian exports are subsequently used in other countries.' the Coalition stated

'Leader of The Nationals Matt Canavan said it was mind boggling that Australian projects could now be stopped based on emissions overseas.' the statement reads

“As part of the Liberal and Nationals plan to scrap net zero, we will stop Australian jobs and resources projects being held hostage by radical green activists who are enabled by Labor governments,” Senator Canavan said.

“Shutting down our mining projects will not lower the global temperature, but it will stop us from building more roads, more hospitals and more schools. 

“We will not let activists destroy Australia with their ideology that makes not one degree of difference.

“We will ensure Commonwealth, State and Territory laws cannot require overseas emissions from Australian resource exports to be considered in project assessment or approval.

“We will also ensure Commonwealth, State and Territory governments cannot refuse, delay, restrict or condition a project because of emissions produced overseas when the exported resource is used.”

Protection will apply during the State or Territory assessment and approval process, with normal State and Territory laws over local environmental impacts to be maintained.

Senator Canavan added the Coalition has also pledged to claw back federal funding for the Environmental Defender’s Office.

“The Liberals and Nationals will not only ensure net zero is dead – we will restore common sense and prosperity for our nation.”

 

Australia’s top court puts fossil fuel developers on notice

Australia’s highest court has just delivered its first-ever decision in a climate case. And it could sour the economic argument for developing new coal and gas projects in New South Wales, and possibly Australia.

This High Court judgement is timely – Australia is co-hosting an international pre-COP31 climate summit in the Pacific this week and is facing renewed pressure from Pacific leaders over fossil fuel projects.

The court’s decision on Wednesday – in a case brought by a community group against mining company MACH Energy over a coalmine expansion – is not a unified legal declaration against fossil fuels.

But this restrained, technical judgement quietly sets a new standard for coal and gas projects in the state – and potentially across the country. It means planning authorities must consider the whole carbon footprint of these projects, including the emissions produced by customers burning these fossil fuels overseas.

Although the decision concerns one specific coal mine – MACH Energy’s Mount Pleasant coal mine in NSW – it directly affects the 17 other coal proposals currently in the state’s planning pipeline.

It could also provide a legal blueprint for how courts across the country handle future cases against fossil fuel projects.

Remind me, what is climate litigation?

Climate litigation involves taking governments or companies – and occasionally individuals – to court in a bid to hold them responsible for climate harms.

There are now thousands of these cases worldwide. After the United States and Brazil, Australia has more of these cases than anywhere else: 193 cases by the end of 2025. This wealth of climate litigation is due to the prevalence of fossil fuel projects in Australia, coupled with lax regulation and high community engagement.

Climate litigation is used because a court can legally require governments and companies to act, in a way that community opposition or political pressure can’t. It is particularly effective where government regulation is slow, weak or missing altogether.

What is this case about?

The Mount Pleasant open-cut coal mine sits near Muswellbrook, in NSW’s Hunter Valley. It was originally approved to run until December 2026, digging up to 10.5 million tonnes of coal each year.

In 2021, the mine’s owner, MACH Energy, sought to extend its life by 22 years, and double its output to 21 million tonnes a year until 2048.

Most of the mine’s climate footprint does not come from the mine itself, but from the burning of the coal it produces. The vast majority of its emissions are classified as “scope 3” – this includes the emissions produced when the mine’s coal is burned overseas.

In 2022, the Independent Planning Commission, the body that decides on major NSW projects, approved the expansion of the mine. But a local community group, the Denman Aberdeen Muswellbrook Scone Healthy Environment Group, challenged that approval in the NSW Land and Environment Court.

The community group argued the planning commission had failed to ask how the mine’s emissions would worsen climate change in the Hunter region. The group also argued the commission breached a NSW planning rule that required it to consider imposing conditions to minimise greenhouse gas emissions, including scope 3 emissions, to the “greatest extent practicable”.

Although the community group lost in the Land and Environment Court, the NSW Court of Appeal unanimously agreed with their arguments, and declared the approval invalid in July 2025. MACH Energy appealed this decision, bringing the case to the High Court in May this year.

What did the High Court decide?

The High Court’s decision to oppose the Mount Pleasant mine expansion was not unified: three judges were in favour, and two against.

The three judges in favour reached the same conclusion. They ruled the Independent Planning Commission didn’t do enough to assess the mine’s scope 3 emissions, or how these might be mitigated or reduced.

They also rejected the idea that scope 3 emissions, when they happen overseas, are someone else’s problem. As Justice Michelle Gordon put it, these emissions have the same detrimental impact no matter how they are categorised.

This means that for every NSW coal or gas project approval, decision-makers must now consider imposing conditions to deal with scope 3 emissions, such as requiring companies to buy carbon offsets.

However, offsets are no silver bullet, as they allow companies to compensate for their current emissions and effectively keep burning the same amount of fossil fuels.

What comes next

Community groups now have a clear, High Court-endorsed basis to challenge approvals where authorities haven’t properly assessed a project’s full carbon footprint.

In NSW, developers of future coal projects will be expected to propose ways to curb their scope 3 emissions, potentially at significant cost. This could dramatically reshape the economic case for continued fossil fuel production in Australia.

The case now returns to the NSW Land and Environment Court, which can suspend the operation of the mine or set conditions on its scope 3 emissions. The latter option, however, may be extremely expensive for MACH Energy.

The High Court’s decision is consistent with other recent rulings across the globe.

In Norway and the United Kingdom, courts have required decision-makers to deal with all greenhouse gas emissions linked to fossil fuel projects, not just those from the project site itself.

And last year, the International Court of Justice found countries are legally required to assess the effects of fossil fuel projects, both in their own jurisdictions and overseas.

While the High Court’s ruling is focused on NSW law, courts and decision-makers across Australia are paying close attention. This landmark decision shows the climate harms of fossil fuels can no longer legally be ignored.The Conversation

The High Court looked at coal climate emissions overseas. But what about emissions at home?

It’s been a big few weeks for coal mines.

Late last month, New South Wales approved the biggest coalmine expansion project in its history, letting Hunter Valley Operations keep digging until 2045. And last week, the High Court of Australia confirmed that the approval of an expansion to another Hunter Valley mine, Mount Pleasant, was invalid.

The debate over the climate emissions impact of both mines has centred on when their coal is burned overseas. The High Court found state planners had looked only at the 2% of Mount Pleasant’s emissions released in Australia, and not given enough consideration to the 98% later released when coal is sold and burned in other countries.

But the emissions that coal mines release in Australia matters, too. They count towards Australia’s climate targets, and Australia is directly responsible for them.

When NSW’s planning commission approved the Hunter Valley Operations mine, it relied heavily on federal rules intended to keep these domestic emissions in check.

But those rules have two problems. First, the methane from open-cut mines is probably underestimated, as I will explain. Second, every coal mine gets the same target for its total emissions (mostly methane, plus carbon dioxide), even though underground mines report nearly six times as much in total emissions per tonne of coal.

Federal rules for both estimating methane and setting emissions targets are under review right now. This is the moment to fix them.

What are the rules?

Most emissions from coal mines are methane, a potent greenhouse gas that escapes from coal seams as the coal is dug up. Tonne for tonne, methane traps about 80 times as much heat as carbon dioxide over 20 years, and it’s behind about a third of global warming today.

Methane from coal mines makes up about 5% of Australia’s emissions.

The federal government manages these emissions through a policy called the Safeguard Mechanism. This gives each big polluter, such as Chevron’s Gorgon gas plant or Qantas’ domestic flights, a yearly emissions limit, which decreases over time.

Facilities whose emissions go over their limit must buy carbon credits, while those that reduce their emissions earn credits they can sell.

How methane is measured

Underground mines measure their methane by testing air pumped out of the mine.

Until recently, many open-cut mines estimated their methane using a state-wide average. But now, large mines must test rock samples drilled from their own site instead. The change has sent reported emissions swinging wildly, yet it changes only the estimate, not the methane actually escaping.

For example, Mount Pleasant’s fell by three-quarters in 2023–24, though it mined more coal. Glencore’s Hail Creek mine in Queensland’s Bowen Basin reported a 159% rise.

These estimates reflect questions over accuracy. In 2023, scientists flew aircraft over 17 Queensland coal mines to measure their methane. Above the underground mines, the readings closely matched what the mines reported. But above the open-cut mines, the aircraft found about 3.6 times as much methane as reported.

Satellite data tell a similar story in NSW, home of both Hunter Valley mines. Analysis by energy think tank Ember found the mines producing two-thirds of the state’s coal released nearly twice the methane officially reported for the whole state. To put it simply, the official figures appear to drastically understate their methane emissions.

The federal government’s own expert panel on methane measurement said last month the aircraft study provides “robust evidence” the estimation method warrants review.

So a mine’s reported emissions can swing up or down, without any real attempt to lower emissions. And if emissions aren’t counted correctly, polluters don’t have to pay for them.

One target, but two very different mines

Open-cut mines dig from the surface, like a giant quarry, and produce more than 80% of Australian coal.

On reported figures, Queensland’s open-cut mines emit about 47 kilograms of carbon dioxide equivalent for every tonne of coal. By comparison, underground mines emit about 267kg per tonne.

Yet, the Safeguard mechanism gives every coal mine the same emissions target: 65kgs a tonne. Each year until 2029-30, every mine’s limit moves towards that shared target.

In other words, they are allowed to emit more per tonne of coal. Mines that emit less than their limit earn credits for the difference, which they can sell.

Open-cut mines earned about 700,000 credits this way in 2024-25, worth about $26 million at current carbon credit prices.

How to fix it

First, the federal government should ensure open-cut mines improve the way they estimate their methane, so their reported figures match what they actually release.

The government is reviewing those methods now. Mine estimates should regularly be checked against aircraft measurements. Over time, open-cut mines should also have to measure their methane, as underground mines already do.

Second, the Safeguard Mechanism should set separate limits for open-cut and underground mines, based on those better estimates, and apply a new limit only where it is tighter than the old one.

On today’s reported figures, that would reduce open-cut mines’ limits by about 1.3 million tonnes a year.

The High Court will force governments to look harder at the coal Australia sends overseas. The methane leaking from mines here deserves the same scrutiny.The Conversation

High Court ruling puts fossil fuel giants on notice: Greens

October 7 2026

The Australian Greens say today’s High Court ruling is a landmark step that strips bare the government's excuses that they are not responsible for the emissions burned overseas. The High Court is making clear that the 80 per cent of our coal and gas that is exported overseas is their responsibility. 

In its first-ever climate judgment, the High Court has dismissed an appeal by MACH Energy over the proposed expansion of the Mount Pleasant coal mine in the Hunter Valley, finding that planning authorities must consider the global climate impacts of a project's emissions and how to minimise damage. 

The ruling puts fossil fuel companies and governments on notice as Australia continues to approve new coal and gas projects amidst Pacific pre-COP and ahead of COP31 where it is leading climate negotiations. Governments and fossil fuel companies are accountable for the climate damage caused by their projects.

Senator Steph Hodgins-May, Deputy Leader and assistant spokesperson for Climate Change & Energy said: 

“In true form, the Prime Minister said he wanted the coal corporation to win this case1, but today, despite his fealty, the local Hunter community has won. 

“Congratulations to the two retired science teachers who spent four years challenging this massive fossil fuel company owned by a billionaire in a Virgin Island tax haven.

“The High Court backed the community in calling out the Labor government for continuing to ignore the climate consequences of fossil fuel projects. This ruling now makes that impossible.

“For too long, big coal and gas companies have tried to pretend that the emissions from their products are someone else’s problem once they leave Australian shores. They’re not.

“When Australian coal is burned overseas, the climate damage doesn’t magically disappear at the port. It comes back to communities here through worsening heat, drought, bushfires and floods.

“This judgment sends a clear message to governments and fossil fuel companies that the climate impacts of their projects cannot simply be ignored or pushed down the line.

“With the HVO expansion and Browse proposal currently on their desk, the Albanese Government should be paying close attention. The ICJ and now the High Court have made it clear - climate impacts must be considered in fossil fuel project assessments. 

“The case shows that Australia’s national environmental laws are broken. Without a climate trigger, communities have to spend years in court to get climate impacts properly considered when the responsibility on government should be clear from the outset.

“You cannot claim to be serious about climate action, to lead climate negotiations at COP, all while continuing to approve new fossil fuel projects and pretending their emissions are someone else’s problem.

“The Greens will keep pushing to make the big fossil fuel corporations profiting from these projects accountable for the damage they are causing, and force Labor to take responsibility for the climate consequences of the projects it approves.”

NSW Government re-commits to expanding climate wrecking gas projects: NSW Greens

October 7, 2026

The NSW Greens have stated the Minns Labor Government has released a new NSW Gas Statement that continues to back new gas extraction, including the Narrabri Gas Project and exploration in western NSW, despite its own Net Zero Commission warning that NSW is off track on its climate targets and that the state must rapidly accelerate renewable energy, electrification and emissions reductions.

Greens MP and spokesperson for justice and solicitor Sue Higginson said “While the Minns Labor Government doubles down on gas as part of our energy plan, unchecked climate change will make the NSW economy $1.5 trillion smaller over the next 50 years. This compares to just $3 billion in direct public benefit from the Narrabri Pilliga Gas project,”

“Communities are already paying the cost of more extreme disasters, higher food costs, lost income and damaged homes and infrastructure. There is no economic case for fuelling more of the problem,”

“Narrabri won’t solve an immediate gas shortage, and Santos has already deprioritised the project. The new western exploration areas are unproven resources that would require years of exploration and development before they could possibly produce gas. The Government itself admits those resources still need to be tested,”

“Every dollar of investment, every public servant and every piece of political capital spent facilitating new gas extraction is capacity that should instead be directed towards getting NSW off fossil fuels faster - electrifying homes and industry, building renewable generation and storage, and removing the remaining barriers to a genuinely renewable economy,”

“Gas is not a transition fuel, it’s just another fossil fuel. New extraction locks in emissions and infrastructure for decades at precisely the point when NSW needs to be accelerating away from fossil fuels,”

“There should be no new coal or gas projects in NSW. The Government should be planning for the orderly decline of existing fossil fuel production and directing investment towards the renewable energy system that must replace it,” Ms Higginson said.

The government stated: ''The NSW Gas Statement provides an overview of the state's gas outlook and the actions being taken to support energy security, economic growth and the orderly transition to a net zero economy.''

''NSW’s energy system is changing rapidly, as ageing coal-fired power stations are replaced by renewable energy, firmed by a significant amount of storage and backed up by gas-fired power stations.

Forecasts from the Australian Energy Market Operator indicate potential gas supply shortfalls on Australia's east coast in the years ahead, highlighting the importance of careful planning to ensure energy security throughout the transition.''

''NSW relies on gas from other states. Securing diverse gas supply for NSW will support industry to access reliable, affordable energy sources and help NSW remain a competitive and attractive investment destination.

''NSW gas production, alongside investment in import terminals, gas pipeline and storage, renewable fuels, electrification and energy efficiency, will safeguard NSW against supply disruptions.

Earlier this year, the Minns Labor Government announced it would open new areas in the state’s Far West for gas exploration. This complements the existing Narrabri Gas Project to help secure a reliable domestic supply for the East Coast. Under the NSW Gas Statement, no new areas will be released for gas exploration.''

''The NSW Government is committed to maintaining a secure and affordable gas supply wherever it is needed, recognising that different sectors and communities will move through the energy transition at different speeds.

''We will also support the uptake of lower-cost and lower-emissions alternatives where they make sense for consumers and businesses, helping reduce energy costs while delivering emissions reductions.''

The NSW Gas Statement is available online.

The document states Key NSW Government actions are:

Securing and diversifying gas supply

  • Supporting approvals for projects that can secure and diversify NSW’s gas supply or address infrastructure constraints, such as the Narrabri Gas Project and its connecting pipelines and the Port Kembla Energy Terminal.
  • Releasing targeted areas for gas exploration in the Far West and retaining existing petroleum exploration licences in the north-west to support future local supply options.
  • Working with the Commonwealth, states and territories on the proposed Domestic Gas Reservation Scheme and related policy settings to ensure gas is available when and where it is needed.
  • Ensuring gas produced in NSW supports Australian gas consumers.
  • Implementing the NSW Renewable Fuel Strategy to support the production of biomethane and other low-carbon fuels.

Overcoming infrastructure constraints

  • Supporting approvals for projects that can expand NSW’s gas transport and storage capacity, such as the East Coast Gas Grid Expansion, or that futureproof infrastructure capacity needed for injecting renewable fuels such as biomethane into the gas network.
  • Providing financial support for the operation of the Newcastle Gas Storage Facility, to ensure gas supply for NSW residents and consumers during peak demand periods.
  • Directing tenders under the Electricity Infrastructure Roadmap to support investment in firming capacity, including gas-powered generation.
  • Implementing the findings of the NSW Gas Infrastructure Review to improve network resilience and reliability and address storage gaps.

Reducing gas demand

  • Extending the Energy Savings and Peak Demand Reduction Schemes to 2050 to support efficient electric upgrades in homes and businesses.
  • Introducing the Home Energy Saver program and supporting the Social Housing Energy Performance Initiative, to help NSW consumers reduce their energy bills through electrification and improve energy efficiency.
  • Developing the new net zero plan to establish the NSW Government’s approach for reducing emissions.
  • Delivering the Low Emissions Industry and Business Decarbonisation Programs, to support emissions reductions.

Minister for Energy Penny Sharpe said:

“The NSW Government remains focused on ensuring households, businesses and industry have access to the energy they need, while building a cleaner, more resilient energy system.

“Supporting electrification and preserving gas for critical uses gives greater certainty to industry, helps households lower their energy bills, and reduces emissions.”

Minister for Natural Resources Courtney Houssos said:

“The Minns Labor Government is taking practical and necessary steps to strengthen the state’s gas supply to power our manufacturing sector and back-up the energy grid.

“Releasing these new areas for exploration, to complement the Narrabri Gas Project, supports a domestic gas supply and provides confidence to households and businesses.

“We are supporting workers and businesses in the manufacturing sector that depend on reliable energy for their industrial processes. Gas will continue to play an important role as our state’s energy mix changes.

“We are also working closely with the Commonwealth to get the policy settings right to drive investment in and secure the gas supply NSW needs.”

However, the Lock the Gate Alliance and local farmers said the NSW government’s released NSW Gas Statement failed to listen to community concerns about proposed gas projects, which will prolong uncertainty and pain for North West communities. 

The statement reasserts the NSW government’s support for the Narrabri Gas Project, which has faced fierce community opposition for more than a decade due to the damage it would cause to NSW’s most productive agricultural land and the sacred Pilliga Forest. The statement also backs maintaining production exploration licenses on the Liverpool Plains and restates support for exploration in the Bancannia and Pondie Range Troughs, following the government’s backflip announced in April.    

After finding out that the NSW government planned to run a limited consultation process to develop this policy, Lock the Gate Alliance alerted affected stakeholders in June about the need to make submissions. This resulted in numerous additional submissions from organisations and individuals that weren’t initially invited to have their say by the NSW government. Concerns for landholders were recognised in the summary of consultation and then ignored in the final policy statement. 

Liverpool Plains farmer Margaret Fleck said: “This process has made clear that the NSW government is prioritising the interests of the gas industry above communities who will pay the direct price of dangerous gas drilling in the North West of NSW. 

"The NSW government’s stubborn commitment to the Narrabri Gas Project, even in the face of major questions around the quantity and quality of gas from the project, just prolongs pain and anguish for communities in the North West. Even Santos is telling its shareholders that it won’t exert any effort on this stranded, controversial project. 

"Proposed gas projects across regional NSW would affect thousands of farmers and Traditional Owner groups including Gomeroi and Barkandji, but the NSW government only met with one Aboriginal group and two farming groups.

"Concerns raised by affected landholders were not addressed in the policy. For example, there is a major risk that landholders hosting coal seam gas infrastructure will not be able to secure public liability and home insurance. This is an enormous risk to farmers, and the NSW government has ignored it.”

Lock the Gate Alliance Clean Industry Coordinator Harriet Kater said: "Unions and community organisations have been calling on the NSW Government to develop a comprehensive gas demand reduction strategy in recognition of the numerous benefits associated with getting off gas, including improved energy security, lower bills for households and businesses, secure jobs and reduced greenhouse gas emissions.  

"Lower gas demand means less gas drilling, helping to protect the Pilliga and North West communities fighting against the land, water and climate impacts from onshore gas expansion. 

"There is plenty of room for improvement in the NSW Government’s household and industrial electrification efforts and all eyes will be on the long awaited Gas Decarbonisation Roadmap due for publication later this year. Modelling commissioned by Lock the Gate found that a 52% gas reduction target by 2035 is achievable for NSW with the right policy settings."

High Court upholds IPC Refusal of Mount Pleasant Coal Mine

On the same day, October 7, the High Court upheld the refusal of the NSW Independent Planning Commission’s Mount Pleasant Coal approval on the grounds that the scope 3 or downstream emissions, the burning of the coal wherever that is, were not properly assessed, despite making up 98% of the development’s projected impacts. 

The IPC’s recent HVO coal approval is also made up of 98% scope 3 emissions and is likely to run into significant legal difficulty following this decision. 

Greens MP, spokesperson for Climate Change and Planning and public interest environmental lawyer, Sue Higginson said,  

“The High Court have exposed the New South Wales coal approval process for the sham it is, and declared that new coal cannot be approved when 98% of the climate pollution are ignored, 

“The High Court have sided with the climate science and declared that the NSW Independent Planning Commission was wrong to ignore downstream emissions when approving a massive new coal project, 

“What an incredible moment in time, that two retired school teachers who have lived and breathed big coal in the Hunter Valley for years and years, Wendy Wales and Tony Lonergan have won the day. They are climate heroes and thanks to their incredible advocacy the Hunter Community will be spared from the horrific impacts of this proposal, 

“Exactly the same as Mount Pleasant, 98% of the emissions from the recently approved Hunter Valley Operations (HVO) coal development are scope 3 emissions. HVO’s Environmental Impact Statement didn’t even account for scope 3 emissions at all, and the High Court has been crystal clear that consent authorities must ensure emissions are minimised to the greatest extent practicable. It seems clear that the approval of HVO fails this test, 

“Lawyers should be running to the Courts right now with this judgement in hand, ready to stop coal approvals in their tracks, 

“The Minns Labor Government has been confronted once again with the legal and scientific reality that new coal is not consistent with our climate targets and laws. Labor Premier Chris Minns should stand up to his ‘good friend’ Stephen Galilee and rule out any new coal approvals in NSW,” Ms Higginson said.

Largest coal mine ever in NSW Approved

Prior to this, on Wednesday September 30 it was announced the largest coal expansion project ever proposed in NSW, the HVO North and South Open Cut Coal Continuation Projects, had been given the green light by the IPC under the Minns Government, despite clear advice from the Net Zero Commission that continued coal mine extensions and expansions are inconsistent with legislated emissions reduction targets. 

The coal mine will generate around 809 million tonnes of greenhouse pollution, including 15.1 million tonnes of direct emissions in NSW and will continue extracting coal through till 2045.

According to the new Carbon Impacts Tracer, emissions on this scale are estimated to contribute 0.00036°C of global heating, expose almost 500,000 people to unprecedented heat, cause the loss of nearly 15 million Great Barrier Reef coral colonies during each bleaching event, and reduce annual crop production by an amount equivalent to the minimum dietary requirements of 276,129 people.

Greens MP, Solicitor and Spokesperson for Climate Change and Planning Sue Higginson said, “This giant mine is the largest coal expansion project in NSW, with 15.1 million tonnes of direct emissions in NSW and more than 809 million tonnes of climate pollution overall,”

“The Net Zero Commission has told the Government plainly that continued coal mine extensions and expansions are inconsistent with our legislated climate targets. The Commission has also warned that approving more coal makes those targets harder to achieve,”

“The latest climate attribution science tells us what 809 million tonnes of pollution means in the real world. Almost half a million people exposed to unprecedented heat, millions of coral colonies lost during bleaching events and substantial losses in food production,”

“I can’t believe the IPC didn’t even follow through with shortening the life of the mine life to avoid some of the greenhouse emissions, it’s an absolute betrayal of the science, the evidence and the voices of our communities who are already suffering the impact of climate change,” 

“The decision acknowledges that this project will contribute to climate change, that NSW is already off track for its 2030 and 2035 emissions targets, and that coal mining emissions are increasing when emissions across the economy need to fall,”

“There is an enormous question mark over the legality of this decision. It flies in the face of our legal and policy frameworks. I wouldn’t be surprised if the decision is challenged in the courts. While these sorts of legal challenges are very difficult and have a David and Goliath aspect to them, people feel compelled to bring them, because these decisions are a matter of life and death,” 

“This is a failure of Labor, they can not keep approving enormous coal expansions and pretend it is taking the climate crisis seriously. The science, the State’s own climate laws and its independent Net Zero Commission are all pointing in the other direction.” Ms Higginson said. 

The Lock the Gate Alliance condemned the Independent Planning Commission’s (IPC) decision to approve a 19-year extension to the Hunter Valley Operations (HVO) coal mine, saying it exposes the failure of NSW’s planning system to prioritise community wellbeing over mining lobby interests.

''HVO’s extension will worsen already poor local air quality, disrupt water resources, and generate more than 800 million tonnes of climate pollution, which will worsen climate-related disasters and cost-of-living pressures across NSW.'' Lock the Gate stated

Community members and organisations made more than 4000 submissions opposing the extension. During public hearings, former Chief Scientist of Australia Dr Penny Sackett gave evidence that this single project would have “significant” consequences for global warming and the pollution it created would effectively undo greenhouse emissions reductions efforts of NSW and Australia.

Lock the Gate Alliance National Coordinator Georgina Woods said: “We are shaken and shocked by this decision, which will go down in history as an infamous betrayal of the public trust. Climate change is already increasing floods and fires in the Hunter, and driving up the cost of living for everyday Australians. It is a deadly threat and the NSW planning system is making it worse. 

“Every person in New South Wales is in harm's way from rising global temperatures. The pollution from this coal mine will fuel further global warming and households, businesses and local councils around the state will be the ones paying the price. 

“Dozens of people from the Hunter and other regions stoically fronted public hearings to share heart-rending personal stories of how climate change is already affecting their lives, including rural firefighters, wildlife carers, and households grappling with rising damage costs. 

“There is no other way to describe this situation than as a catastrophic failure of the NSW planning system to protect people, from the cities and the bush, from worsening global warming.” 

Last year, a landmark NSW Net Zero Commission report warned that the expansion of coal mining was not consistent with NSW’s commitment to prevent dangerous levels of global warming. 

Two more large coal mine expansions are expected to be determined by the Independent Planning Commission before the state election next year, and several more smaller expansions are likely to be determined by the Department of Planning in the same timeframe. There are more than a dozen more coal mine expansion projects in NSW’s planning pipeline. 

The Decision Summary from the IPC states:

The NSW Independent Commission has determined to approve the HVO North and South Open Cut Coal Continuation Projects SSD-11826681 and SSD-11826621 (the Applications).

The Applications, made by Hunter Valley Operations Pty Ltd, sought approval for the continuation of open-cut mining at the HVO complex until the end of 2045 for HVO North and the end of 2042 for HVO South. The Project includes 24/7 operations, extensions of existing mining areas and the mining of deeper coal seams.

The Commission held a three-day public hearing and received more than 10,000 written submissions on the Applications. Issues of focus in submissions included the greenhouse gas (GHG) emissions of the Project, the impact on climate change and NSW’s capacity to meet legislated GHG targets, and the treatment of offsets. Submissions also emphasised the economic and social benefits of employment at the mine (up to 1,407 jobs), the flow on benefits to local businesses and communities and the negative impacts that would result from abrupt mine closure.

The Commission also considered evidence in relation to other impacts of the Project, including on water, dust, noise, biodiversity, Aboriginal cultural heritage and the thoroughbred industry.

In reaching its determination the Commission paid careful attention to the changes that have been made in recent times to the legislative and policy frameworks relating to greenhouse gas emissions and coal mining, and to advice provided by the Department of Planning, Housing and Infrastructure clarifying the operation of these policies as they relate to the imposition and regulation of conditions.

The Commission considered whether an approval period shorter than that proposed in the Applications could retain the Project’s economic and social benefits while avoiding a portion of the Project’s GHG emissions. In granting approval for the full period, the Commission accepted evidence from the Applicant concerning the impact of a shorter period on mine planning, capital recovery and operational integration.

GHG emissions from the Project will contribute to climate change, with 98% of these emissions occurring in overseas jurisdictions where the product coal is consumed. The applicable policy and legislative frameworks for reducing those emissions refer to the operation of the Paris Agreement and nationally determined contributions as the mechanism to be used to protect the people, economy and environment of NSW, with the EPA as the regulator of GHG emissions. Accordingly, the Commission has imposed conditions intended to limit coal exports to jurisdictions that have policies for reducing greenhouse gas emissions consistent with the goals of the Paris Agreement.

The Project’s domestic emissions have also been conditioned, including requirements for minimisation and offsets. Even though offsets outside of NSW cannot count towards NSW targets, such offsets – including those under the Safeguard Mechanism – still provide a real environmental benefit that the Commission can and should take into account. The Applicant is also required to take reasonable and feasible measures to maximise the use of renewable energy from four years from the commencement of the development, which consistent with new requirements for data centres. With these conditions, the GHG impacts of the Project are managed effectively within the parameters of the NSW and Commonwealth statutory and policy regimes, and the international Paris Agreement which they both reference.

The Commission has assessed the Project's likely impacts, the measures proposed to avoid, minimise, mitigate, offset or manage them, and the residual impacts that would remain. The Commission finds that the residual impacts of the Project are, on balance, outweighed by its benefits to the Hunter region and NSW, including continued employment, economic activity, support for local business, ongoing royalties and taxation revenue. The continued operation of the HVO complex would provide economic stability for the Hunter region and support a more orderly transition for workers, businesses and communities as the coal industry changes over time.

Background

Lock the Gate states the Hunter Valley Operations Continuation Project is a joint Yancoal and Glencore venture, 24km northwest of Singleton. It was the largest coal project ever proposed in NSW. It will: 

  • Produce 430 million tonnes of coal over its lifetime.
  • Generate 800 million tonnes of climate pollution. 
  • Dig enormous coal pits right beside the Hunter River, putting the waterway at risk.
  • Worsen health-threatening air pollution in Singleton and Muswellbrook, where public air monitors show pollution regularly exceeds legal limits. 
  • Clear a crucial remnant of vegetation in a heavily cleared landscape, bulldozing three threatened ecosystems.

Given the October 7 High Court judgement the IPC decision may be challenged in court.

 

Call-Out for Iconic Trees

The council is inviting the community to nominate remarkable public trees for inclusion on the new Iconic Tree Register, with nominations opening 25 September 2026.

The register will recognise significant public trees that contribute to the area’s natural beauty, biodiversity, history and sense of place.

Nominated trees must meet one or more criteria, including visual, ecological, historical,  botanic or social significance.

Most public native and exotic trees are eligible, including those exempt for removal under council or State Government controls if they demonstrate they meet the criteria.

The council stated it will launch the official Iconic Tree Register platform in January 2027, after the first nominations have been assessed. The interactive platform will contain images, locations and informative details of each tree.

A council chosen 'panel with expertise in biodiversity, arboriculture, heritage and landscape architecture will assess nominations against the Iconic Tree Register criteria' the statement out of the council says.

The first intake will allow approximately 30 eligible trees to be recommended for inclusion, with future assessment rounds happening on a regular basis.

Listed trees will be managed under the council’s ''Tree Management Policy'' and monitored for health and condition.

For more information and to nominate, visit the council webpage.

Antarctica’s ice loss is locked in, and extra snowfall won’t save it – that’s bad news for low‑lying coastal areas elsewhere

A glacier front meets the water.

Sea-level rise is one of the most visible signs of climate change, one that is threatening low-lying coastal communities around the world. Today, about 1 billion people live in coastal areas; about 100 million live within 1 meter (3.3 feet) of sea level, highly exposed to coastal flooding.

Over the long term, when it comes to future sea-level rise, one place matters more than any other: Antarctica.

The frozen continent holds enough ice to raise global sea level by about 190 feet (58 meters). Yet scientists have disagreed on a fundamental question: Will Antarctica gain more ice than it loses this century or lose more ice than it gains?

In a new study published in the scientific journal Nature Geoscience, we looked at hundreds of thousands of potential futures and the impact of each on the ice sheet.

We found that Antarctica’s ice loss this century is locked in – even if the world limits global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit), the 2015 international Paris climate agreement’s most ambitious goal.

Why the Antarctic ice sheet is so hard to predict

The Antarctic ice sheet’s future depends on a chain of events.

Greenhouse gas emissions from vehicles, coal- and natural gas-fueled power plants and other sources around the world determine how much the ocean and air around Antarctica warms. That warming shapes how ice shelves around the continent’s margins melt, and how quickly the glaciers behind them slide over the bedrock. When those ice shelves thin or collapse, studies show the glacier flow speeds up.

A European research team explains ways Antarctica is vulnerable to ice loss from the ocean and how models work. TiPACCS.

Each step relies on assumptions that scientists have yet to agree on, such as how ice shelves collapse. Different assumptions give different answers, and because each step feeds the next, the differences grow – what scientists call cascading uncertainty. As a result, research teams around the world can’t agree on whether Antarctica will gain or lose ice this century.

Snow is part of the puzzle. Warmer air holds more moisture, so as temperatures rise, more snow will likely fall on Antarctica. In some projections, that extra snow outweighs the ice lost to the warming ocean, and the ice sheet actually grows.

Auditioning possible futures

A big reason for this persistent disagreement involves the cost of computing.

Each ice-sheet simulation runs with just one set of assumptions for every step in the chain, from how much greenhouse gas we emit to how the ice behaves. One run can keep a supercomputer busy for days, so no team can test every plausible combination.

Our team of data scientists, glaciologists and oceanographers took a shortcut. An international project called the Ice Sheet Model Intercomparison Project, or ISMIP6, has built a large archive of Antarctic simulations showing how the ice responds under different circumstances. We trained a physics-informed machine learning model on that archive to learn how each simulation’s outcome depends on its physical assumptions, such as how easily ice slides over bedrock. The machine learning model does in a fraction of a second what took the original models days, predicting sea-level change with similar accuracy.

NASA’s Grace satellite has tracked ice mass loss over the years. NASA

That speed let us run millions of combinations and check hundreds of thousands of possible futures against data from satellites that weigh the ice sheet from space by sensing tiny changes in Earth’s gravity. Only scenarios that were able to match what the satellites have seen since 2002 made the cut.

The scenarios that did make the cut point one direction: Antarctica will lose more ice than it gains this century, even if humanity is able to limit global warming to 1.5 C.

That means Antarctica will contribute more to sea-level rise that’s already being driven by melting of the Greenland ice sheet and mountain glaciers and from warming ocean temperatures that cause water to expand.

What a clearer forecast can do

The biggest lessons from our study are that greenhouse gas emissions matter and extra snowfall won’t save Antarctica. Every ton of greenhouse gas that humans can avoid releasing today reduces how much ice Antarctica loses this century, and the benefit – slower and less sea-level rise – lasts for hundreds of years.

In a scenario with very high emissions, our results show a potential faster domino effect. A fast-warming ocean thins the ice shelves, weakened shelves break apart, and glacier ice flows into the ocean faster. Each step makes the next one easier. Together, these steps could add up to 10 inches (25 centimeters) of sea-level rise from Antarctica alone by 2100 – enough to permanently flood the homes of more than 10 million people.

On the left, how greenhouse gas emissions change the climate, including sea ice, ocean and atmospheric dynamics, which influence one another and levels of global warming. On the right, what goes into an ice sheet model, including ice shelf melt and collapse and how the ice slides. Every stage adds uncertainty. Yucheng Lin

Of more than 20 physical assumptions about Antarctica, three matter most for understanding future sea-level rise: how ice shelves respond to a warming ocean, how ice slides over bedrock, and how fast the ocean and air around Antarctica warm. Gaining a better understanding of these processes would do the most to sharpen sea-level projections.

What’s still missing

Our study is far from the final word.

Some processes are missing from today’s simulations, so our machine learning model can’t learn about them – for example, how ice cracks and breaks, and how rivers and lakes beneath the ice sheet change over time. Any of these could change our understanding of how quickly Antarctica’s ice reaches the sea and whether coastal communities have enough time to adapt.

What our study does offer is a much faster way to test combinations of assumptions that are too costly to simulate one by one. That provides a clearer basis for the decisions coastal communities around the world are already having to make.The Conversation

NSW Threatened Species Scientific Committee provisional listing on an emergency basis: Hibbertia sulcinervis Toelken in Sydney Basin area

Announced; Friday October 9 2026

The shrub Hibbertia sulcinervis Toelken has been provisionally listed as a critically endangered species on an emergency basis.

Hibbertia sulcinervis Toelken is endemic to the Sydney Basin Bioregion of NSW. 

The determination states:

Hibbertia sulcinervis Toelken (family Dilleniaceae, CHAH 2026; PlantNET 2026) belongs to the Hibbertia stricta species-group (Toelken and Miller 2012) and is described as: “Shrubs to 1.3 m high, moderately branched; stems with prominent flanged leaf bases, puberulous when young, becoming glabrous, with short intrapetiolar hair tufts. Leaves shortly petiolate; lamina linear, (7.4–)10–30(–34.5) × 0.8–1.3 mm, flat and glabrous adaxially, with a broad central vein deeply recessed between strongly revolute margins abaxially, the leaf undersurface partly concealed; apex acute to pointed. Flowers terminal on main and axillary branches, shortly pedicellate; primary bract linear-triangular to linear-elliptic, caducous.

Sepals glabrous, outer lanceolate with a faint central ridge, inner elliptic with scarious margins. Petals yellow, cuneate-obovate, 4.2–7.4 mm long, emarginate. Stamens 6 or 7, in a single cluster, the central stamen longer. Carpels 2; ovaries broadly obovoid, shortly hirsute, with 4 ovules.” (PlantNET 2026).

Hibbertia sulcinervis is endemic to the Sydney Basin Bioregion of NSW (Commonwealth DCCEEW 2024a, 2024b). Currently known and extant records of this species are clustered in Yellomundee Regional Park, at the southern end of the Hawkesbury local government area (LGA), near the Nepean River (ALA 2026). The holotype of this species was collected at Nortons Basin (along the Nepean River, ~22 km south of the currently extant records, Penrith LGA) in 1965 (Toelken and Miller 2012). A specimen labelled “aff. Hibbertia acicularis” was collected from the Nortons Basin area (Crown or freehold land) in 1989 and may be attributed to Hibbertia sulcinervis (P. Rossington in litt. July 2026; RBGDT 2026). However, no individuals have been detected in subsequent surveys of this locality (albeit not comprehensive), and it is possible they are locally extinct at this site (P. Rossington in litt. July 2026).

If Hibbertia sulcinervis is locally extinct at the Nortons Basin site, the distribution of this species would meet the IUCN (2024) definition of severely fragmented because it occurs in a single subpopulation that may go extinct with no known source from which that site could be recolonised.

The extant population of Hibbertia sulcinervis is estimated to include 50–250 mature individuals in Yellomundee Regional Park, with zero individuals at Nortons Basin (P. Rossington in litt. July 2026). Seedlings were also common at the Yellomundee site at the time of writing (P. Rossington in litt. July 2026).

There is an inferred continuing decline in habitat quality for Hibbertia sulcinervis due to incidental damage to vegetation and soils by mountain bike activities, invasion by Lantana camara (a shrub) and Eragrostis curvula (a grass), and an increased likelihood of high frequency fire, which may disrupt the species’ life cycle.

More information on the species can be found on the Threatened Species Scientific Committee's (the Committee's) Determinations for provisional listing on an emergency basis webpage.

In the near future, the Committee will make a preliminary determination regarding this proposal, which will be placed on public exhibition. Public submissions will be invited at that time.

Land purchase brings pink lakes into the NSW national parks estate

Announced: Thursday October 8 2026

'For the first time, pink lakes will be protected within the NSW national parks estate, following the joint purchase of Pulgamurtie Station by the Minns and Albanese Labor Governments', the NSW government has stated.

'Located 235 kilometres north-east of Broken Hill, Pulgamurtie Station will protect more than 74,000 hectares of outback landscape and provide a home to more than 70 threatened species including the iconic brolga, pink cockatoo and slender darling pea.

Its most extraordinary features are two striking pink lakes, which are among NSW’s most spectacular natural wonders. Pink lakes are rare in NSW, with many appearing only seasonally. Their distinctive hues are created by naturally occurring microorganisms, including algae and bacteria, that thrive in highly salty water and produce pink pigments.

The landscape also features sweeping outback plains, rolling sand dunes and thriving wetlands. Its larger lakes and wetlands provide critical feeding and breeding grounds for thousands of waterbirds, including migratory species that travel between Australia, Russia, China and Japan.

Rich in Aboriginal cultural heritage, the property forms part of the significant Dreaming songlines and contains historic stone artefacts, hearths and grinding stones.

Located along the Silver City Highway, Pulgamurtie will become a new destination for visitors to Far West NSW. NSW National Parks and Wildlife Service (NPWS) will explore a range of potential visitor experiences, including campsites near the larger lakes, day-use areas, walking trails and scenic drives, with opportunities for birdwatching and taking in views towards the Koonenberry Range.

Acquisitions such as Pulgamurtie help protect landscapes and ecosystems that are under-represented in the reserve system, while creating new tourism opportunities and supporting investment in regional communities.

National parks play a vital role in supporting Western NSW communities and economies, contributing $433 million to the region annually and supporting nearly 9,000 jobs.

The Albanese and Minns Governments are jointly investing to purchase high-priority conservation properties like Pulgamurtie, for protection through the Australian Bushland Program.

Strategic land purchases of this kind have assisted the Albanese Government to protect more than 25 per cent of Australia’s land mass, which is crucial to restore the nation’s biodiversity.

NPWS will now undertake ecological and cultural heritage surveys to guide the property’s future management. This will include feral animal and weed control, as well as protection of threatened species and cultural heritage.

NPWS will continue to work closely with members of the Malyangapa Aboriginal Community, neighbouring landholders and other stakeholders as this planning progresses.

Pulgamurtie Station was on the market for around two years and was acquired after it failed to meet its reserve at public auction. NPWS has purchased five of the 60 properties sold in Far Western NSW in 2024 and 2025.' the NSW Government's statement says

Federal Minister for the Environment, Murray Watt, said:  

“Australians love spending time in the bush and this purchase will protect more of it for future generations.

“With our natural environment under significant pressure, the Albanese Government is committed to protecting and restoring more land across Australia.

“Through our partnership with the NSW Government, we’re helping secure important habitat and expand the network of protected areas in places that deliver the greatest conservation benefits.

“By protecting and conserving diverse areas of NSW, we’re supporting many threatened species and the habitats they call home.”

NSW Minister for the Environment, Penny Sharpe, said:

“These will be the first pink lakes protected by the NSW national park estate. This is a once-in-a-generation conservation and tourism opportunity that will protect these spectacular landscapes and allow more people to experience them.

“Few places capture the scale and diversity of the NSW outback quite like Pulgamurtie, where a mosaic of wetlands, lakes and rolling arid plains exist side by side.

“This is a critical investment in conservation that will help safeguard this unique landscape, its wildlife and its rich cultural heritage for generations to come.”

Representative member of the Malyangapa Native Title Board, Mark Sutton, said: 

“The Malyangapa people are supportive of the continued expansion of protected areas in Far West NSW.

“The acquisition of Pulgamurtie ensures that representative landscape types and Aboriginal cultural heritage will be protected.

“We look forward to engaging with National Parks and Wildlife Services to create another recreational destination for locals and visitors alike.”

From rescue to recovery: 250 turtle eggs offer hope for Gwydir wetlands

Announced: Friday October 9 2026

The NSW Government has announced more than 250 turtle eggs are now incubating after being laid by native turtles rescued from drying mud in the Gwydir wetlands earlier this year.

On March 18 2026 the Nature Conservation Council of NSW (NCC) was raising the alarm over a looming environmental crisis in the Gwydir Wetlands, where critical environmental water is being withheld in Copeton Dam. [5.]

''There appears to be a new, lower level of risk acceptance by WaterNSW to release environmental water if that water passes over private property, creating an urgent and unacceptable situation for the region's fragile ecosystems.'' NCC stated

Revelations from the NSW Parliament’s Budget Estimates hearings highlight this concerning shift in river operations. During questioning on March 4, 2026, WaterNSW Chief Executive Officer Andrew George confirmed that environmental water deliveries are being restricted. 

When asked about the decision-making process for delivering environmental water to the Gwydir Wetlands, Mr George stated:

"Quite simply, we do not have the authorising environment to flood private property.”

"... we would be breaking the law if we were passing water over private property. We are not authorised to do that without the private property owner's explicit permission.” 

This refusal to release environmental water, which has been delivered successfully for years, is already having devastating consequences on the ground. At the Gingham Waterhole in the Gwydir Wetlands, one of the last strongholds for the broad-shelled turtle is on the brink of collapse as the waterhole rapidly dries. 

NCC insists that environmental protection must be prioritised, in accordance with the principles and duties outlined in the NSW Water Management Act 2000. 

Mel Gray, Water Campaigner, NCC stated in March: 

“Environmental water orders are specifically designed to respond to ecological emergencies like the one unfolding at Gingham Waterhole.

"This is an urgent, unacceptable situation.

"The NSW Water Minister, Rose Jackson, must act swiftly to ensure environmental water can be released as it has been for years.

“We cannot allow bureaucratic or legal stand-offs to result in the extinction of local populations of native species while the water they desperately need sits idle in a dam."

The NCC called on Minister Jackson and WaterNSW to immediately resolve any perceived legal impediments, allowing the release of environmental flows to the Gwydir Wetlands before the broad-shelled turtle population is lost forever.

One Month On: Everything Dying

However, a month later the water has not been reinstated and now researchers from the University of New England are working to dig the turtles out of the drying sludge before all of them are lost.

The Gwydir Wetlands are within the northern part of the Murray-Darling Basin, the country's largest river system. The wetlands are one of Australia's designated Ramsar sites, listed as a wetland of international importance protected under the Ramsar international convention.

Under the convention, the Gingham and Lower Gwydir parts of the wetlands are protected due to their support for nationally listed threatened species.

The NSW Department of Climate Change, Energy, the Environment and Water (DCCEEW) records state the wetlands are crucial for the biological and ecological functioning of the Murray-Darling Basin bioregion.

The eastern longneck, broadshell and Murray River turtles are three species of turtles that call the Gingham Waterhole home.

Populations of all three species have been affected; however, it is the collapse of the Murray River turtle population that is of most concern, with conservationists fearing they could soon disappear from the area completely.

"We have managed to dig up 40 turtles," Dr Bower from UNE stated

"I know from previous trapping sessions there are upwards of 300 turtles in the catchment.

"We have already lost a proportion of the population due to the dry conditions … the longer the waterhole is allowed to be dry, the more turtles we will lose."

Field surveys conducted last month by freshwater turtle researchers revealed a worsening ecological crisis at the site.

Deborah Bower said if the waterhole dries completely, the broad-shelled turtle population there will almost certainly be lost.

“We are watching the collapse of a turtle population in real time,” Professor Deborah Bower said.

“The Gingham Waterhole has supported multiple turtle species for decades.

“Importantly, Copeton Dam currently holds over 800 GL, including approximately 217 GL of environmental water available for delivery before July, 2026, presenting a clear and immediate opportunity to intervene.”

The Gingham watercourse supports four internationally important Ramsar-listed sites in the Gwydir wetlands region near Moree. Wildlife in the area relies on rain and floods, as well as environmental flows managed by state and federal governments in support of the Murray-Darling basin plan.

Dr Bower said researchers have found approximately 15 dead turtles.

She said there was no way to know how many turtles were buried beneath the surface, and she had to physically feel for them in the mud to find them.

"They use digging into the mud as [an] adaptation. They can survive for a period of time in the mud," she said.

"I don't know how many we will lose in this event."

Turtles that have been rescued were transported to Taronga Western Plains Zoo.

Dr Bower said a large fishkill has also resulted from the low water levels, and nearby animals like kangaroos were being forced to move to nearby private land in search of food and water.

The Gwydir wetlands in north-west NSW provide critical habitat for native wildlife, with the Gingham watercourse supporting four internationally important Ramsar-listed wetland sites.

After the University of New England raised the alarm that the turtles were becoming trapped in a rapidly drying waterhole, a rescue mission was initiated by the NSW Government to retrieve as many turtles as possible.

What started as an operation to collect turtles quickly evolved into a unique project, when many of the 39 rescued turtles arrived carrying eggs. The turtles were taken to Taronga Western Plains Zoo’s specialised rehabilitation facility, where they received veterinary care and subsequently laid more than 250 eggs.

The eggs are now being incubated in a temperature-controlled facility at Taronga’s Platypus Rescue HQ. The hatchlings are expected to emerge over the coming year and will be progressively released into the wild, boosting local turtle populations and helping secure the future of turtles in the Gwydir wetlands.

Reintroduction of the rescued adults to the healthy Gwydir wetlands has already begun. Ten Broad-shelled Turtles and three Murray River Turtles were recently released following comprehensive health assessments.

The remaining turtles are expected to follow later this year as conditions allow, helping to re-establish a healthy ecosystem.

Minister for the Environment Penny Sharpe said:

“Conservation isn't always about following a set playbook. Sometimes a crisis creates an opportunity to do something truly ground-breaking.

“By rescuing these turtles and safeguarding more than 250 eggs, we've turned a potential loss into a remarkable opportunity for species recovery.”

Minister for Water Rose Jackson said:

“This is a powerful reminder that when governments listen to the science and move quickly, we can make a real difference for the environment.

“What could have been a story of loss has become a story of recovery, innovation and hope for the future of the Gwydir wetlands.”

Taronga Zoo Wildlife Conservation Officer Dr Phoebe Meagher said:

“Since arriving in Taronga’s care, it’s been a real team effort with the turtles undergoing health assessments, veterinary monitoring and supportive husbandry to aid their recovery and prepare them for their return to the wild.

“To rehabilitate these rescued turtles to a point where they can begin to be returned to the wild is a milestone in itself, but to know that there are more than 250 eggs incubating that could further supplement wild populations is incredibly encouraging for the future of this species.”

Legislation introduced to create Great Koala National Park

Announced: Tuesday October 13, 2026

Legislation to create the Great Koala National Park has been introduced to NSW Parliament by the Minns Labor Government, revealing new details about how the park will protect koalas while keeping forests open for people to explore and enjoy, the NSW Government has announced.

'The National Park Estate (Great Koala National Park Reservations) Bill 2026 will add more than 178,000 hectares of state forest and other Crown land to the national park estate on the NSW Mid North Coast, protecting important habitat for an estimated 12,000 koalas, 36,000 gliders and more than 100 threatened species.' the government said in a released statement

'Combined with existing national parks and reserves, it will be one of the largest parks in NSW, creating a protected area spanning more than 475,000 hectares.

The Bill includes different reserve categories across the park, allowing a wide range of recreational activities to continue alongside conservation.

Most of the newly added state forest and Crown land will be reserved as national park, ensuring long-term protection of important environmental and cultural values. Thirteen per cent of the added land will be designated regional park, supporting more intensive recreation and community activities.

Visitors will be able to enjoy a range of activities including bushwalking, trail running, camping, kayaking, canoeing, horse riding, trail-bike riding, four-wheel driving, fishing and mountain-bike riding, as well as dog walking in select reserves.

The reserve categories have been informed by feedback from the community and recreational groups about how they currently use these forests and what they want to see in the future. This highlighted strong support for protecting wildlife and maintaining recreational access.

The Bill allows the Minister for the Environment to approve motor racing events on existing roads in regional parks within the Great Koala National Park in appropriate circumstances, recognising the long history of car rally events in the region.

The Minns Labor Government continues to support affected workers and communities every step of the way. A comprehensive support package is in place for those workers and businesses, including redundancy support, retraining and upskilling assistance, relocation support, and access to financial and legal guidance and mental health services.

The Bill includes a provision enabling Forestry Corporation staff to be appointed to suitable roles within NSW National Parks and Wildlife Service, helping retain valuable local skills, experience and knowledge within the region.

The final creation of the Great Koala National Park is conditional on the Clean Energy Regulator's registration of the carbon project.' the government said

Minister for the Environment Penny Sharpe said:

“The Great Koala National Park is one of the most important things we can do to save koalas in NSW. It is also about creating an area that people can explore and enjoy for generations.

“From bushwalking and canoeing to mountain-bike riding and camping, we’ve listened to how people want to enjoy the park and we’re making sure that while we save koalas, the Great Koala National Park can also be a world-class area for recreation.”

Minister for Agriculture and Regional NSW Tara Moriarty said:

“We made a promise to create a Great Koala National Park and to support workers, and we’re delivering on that commitment. Alongside this park, we’re rolling out a comprehensive package to help support impacted forestry workers.

“We’re also legislating a pathway for eligible Forestry Corporation workers in the area to keep using their skills and strong connection to the land in the NSW National Parks and Wildlife Service.”

Minister for the North Coast Janelle Saffin said:

“We’ve listened closely to local families, outdoor enthusiasts and North Coast communities to get this balance right.

“The Great Koala National Park delivers crucial protection for our koalas and native wildlife while creating world-class recreation opportunities that will boost local tourism and support North Coast businesses.”

The Nature Conservation Council NSW (NCC) has welcomed the legislation, which will protect some of the state's most important koala habitat and wildlife corridors. 

NCC Senior Forest Campaigner Clancy Barnard said: 

“After more than ten years of campaigning, it's fantastic to see the Great Koala National Park legislation finally reach Parliament. 

“What started as an idea more than a decade ago, inspired by China's panda reserves, has grown into one of the largest new national parks in NSW. 

“The original 175,000-hectare proposal has now grown to more than 178,000 hectares, with the recent addition of 386 hectares of Crown land securing even more vital habitat for koalas and more than 100 threatened species. 

“This is a tremendous achievement for the thousands of people who have campaigned, advocated and worked tirelessly to make this park a reality. 

“Polling has consistently shown that more than 85% of people in NSW support the Great Koala National Park. This is something people across the political spectrum can celebrate, and we encourage all members of Parliament to support the legislation. 

“We applaud the NSW Government for delivering on its commitment to establish this park and for its work to ensure the park delivers for local communities as well as wildlife. 

“It's particularly encouraging to see plans for improved recreational opportunities, including free campsites and continued access for dog walkers, mountain bikers and horse riders. This will see more people have access to these magnificent forests. 

“For those of us living on the Mid North Coast, it’s particularly exciting to see more than $140 million in new funding flowing into our region, supporting conservation, restoration, park management and local jobs. 

“The creation of new Aboriginal ranger positions, employed through Aboriginal Community Controlled Organisations, is another exciting step towards placing First Nations knowledge and leadership at the heart of caring for Country. 

“The Great Koala National Park is a huge achievement built on more than a decade of community campaigning, and that work continues. 

“It was devastating to see almost 10,000 hectares of the proposed park logged before the Government finally declared a moratorium, on top of decades of intensive logging under previous governments. 

“These forests need significant investment in restoration, weed management and ongoing fire management, so it’s extremely pleasing to see the Government commit to funding this work. 

“Logged forests are more vulnerable to severe bushfires, and the challenge now is getting enough boots on the ground to repair the damage. We welcome the Government’s investment and expect that commitment to continue for decades to come. 

“We’ll continue working to protect important koala habitat across NSW and secure an end to native forest logging for good. That’s what the community wants, and that’s what we’ll keep fighting for.” 

West Gables biodiversity certification application: Have Your Say

An application has been made by Stockland Development Pty Ltd and Allam Land No. 11 Pty Ltd for biodiversity certification of land at Old Pitt Town Road and Boundary Road, Gables.

The application is open for public comment until 26 October 2026.

Biodiversity certification is a government created and sanctioned mechanism that enables developers to destroy habitat and wildlife. The certification process identifies areas that can be developed/destroyed after they are certified and measures to ''offset the impacts of development'' have been approved (money handed over). The NSW Government's Biodiversity Credits Market Sales Dashboard lists what can be bought or paid for - residents may be surprised by how cheap it is to accelerate extinctions.

This one is for around 76.42 hectares of land at West Gables.

The supporting documentation for this one points out, in just one instance, that:

'Three threatened microchiropteran bats were recorded as definitely present across the BCAA during surveys including.

• Micronomus norfolkensis (eastern coastal free-tailed bat) – ecosystem credit  species

• Miniopterus orianae oceanensis (large bent-winged bat) – dual credit species

• Myotis macropus (southern myotis) – species credit species

An additional four threatened microbat species were also potentially present, including.

• Falsistrellus tasmaniensis (eastern false pipistrelle) – ecosystem credit species

• Saccolaimus flaviventris (yellow-bellied sheathtail-bat) – ecosystem credit species

• Scoteanax rueppellii (greater broad-nosed bat) – ecosystem credit species

• Vespadelus troughtoni (eastern cave bat) – species credit species

Of these fauna species, only one requires offset to be calculated for impacts to habitat, being southern myotis. A species polygon has been provided for southern myotis and offsets calculated. Ecosystem credit species do not require the preparation of a species polygon. Dual credit species and species credit species require the preparation of a species polygon, unless there is no breeding habitat within the BCAA or within 2 km of the BCAA. No breeding habitat such as caves, cliffs, disused mines or tunnels were present within the BCAA or within 2 km of the BCAA. Therefore, no species polygon for eastern cave bat, or large bent-winged bat was required.'

The proposed BCAA is bordered by Old Pitt Town Road to the south and Boundary Road to the west, with future residential communities to the north, east and south. Remnant vegetation and regrowth vegetation is present belonging to three native plant community types (PCTs):

  1. Cumberland Shale Plains Woodland - listed as critically endangered (to extinction)
  2. Cumberland Shale-Sandstone Ironbark Forest, - listed as critically endangered (to extinction)
  3. Southern Lower Floodplain Freshwater Wetland - listed as endangered (to extinction)

Gables is 52 kilometres west of the Sydney central business district in the local government area of The Hills Shire. The Gables is a residential development within the suburb that is currently being developed by Stockland. It is the biggest master planned community in The Hills District and covers 330 hectares (820 acres). When The Gables was first planned in 2015, it was planned to comprise over 4,000 dwellings, a primary school, two sports fields, a 5.5-hectare (14-acre) town centre and a 4-hectare (9.9-acre) lake central to the development.

Celestino was the original developer of The Gables until March 2020, when Celestino sold the remaining 293 hectares (720 acres) of undeveloped land to Stockland for A$415 million. At the time of the sale, Celestino had already developed 994 dwellings.

As part of the biodiversity certification process, the applicant must make the application available on their website and invite the public to make submissions on the application. 

To view the application including the Biodiversity Certification Assessment Report and application form, and to make a submission, please visit West Gables Biodiversity Certification Application

After submissions close, the applicant must provide a report to the Department of Climate Change, Energy and the Environment that includes the applicant’s response to any submissions from the public.

NSW Snapper Harvest Strategy: Have Your Say

The government is seeking feedback on a draft harvest strategy for NSW Snapper. Share your views on the draft harvest strategy and management framework, which will contribute to the sustainable management of Snapper in NSW.

Public consultation commenced on 1 September 2026 and was initially set to close on 18 October 2026. The consultation period has been extended until 15 February 2027 to ensure opportunity for all stakeholders to provide feedback.

A draft harvest strategy for NSW Snapper has been developed, along with a new stock assessment identifying the stock is at sustainable but low levels.

Documents

The government states on the consultation webpage:

'Harvest strategies are a best-practice way to manage fisheries. They provide a clear plan for balancing environmental, economic, social and Aboriginal cultural interests while helping to keep fish stocks healthy for future generations.

A new integrated stock assessment has estimated the NSW component of the Snapper stock to be approximately 23% of unfished biomass. The assessment indicates the NSW stock has been building from lower levels since the 1990s, so there is some confidence stock biomass will continue increasing under similar catch levels.

The harvest strategy sets clear goals to build the NSW stock to target levels. The first goal is to build the stock to 30% of its unfished biomass. Over time, the aim is to build the stock further to 50% of unfished biomass.

To help achieve this building goal, the harvest strategy sets initial total annual catch (fishing mortality) to 300 tonnes per year, and a defined share to the commercial and recreational sectors. Assessment modelling estimates building to 30% of unfished biomass in 2035 under this level of total catch.

Based on current data, the following management changes would be needed to keep Snapper catches at or below the target level, and within sector shares. These arrangements will be reviewed and updated before commencement and as new information becomes available:'

*Recreational and charter boat limits are not proposed for Snapper.

**Current data indicates a monthly limit of around 950 kg per endorsement holder. Limits will be recalculated before commencement and for each fishing period.

Have your say by filling in a submission form HERE

Consultation will be open from Tuesday 1 September until Monday 15 February 2027.

Your feedback will help to finalise the harvest strategy and management actions to improve the long-term health of the NSW Snapper stock. Please review the harvest strategy and FAQs for further information.

NSW Yellowtail Kingfish Harvest Strategy: Have Your Say

The Government is seeking feedback on a draft harvest strategy for Yellowtail Kingfish in NSW. Share your views on the draft harvest strategy and management framework, which will contribute to the sustainable management of Yellowtail Kingfish in NSW.

Public consultation commenced on 1 September 2026 and was initially set to close on 18 October 2026. The consultation period has been extended until 15 February 2027 to ensure opportunity for all stakeholders to provide feedback.

The government states on the consultation webpage:

'A draft harvest strategy for NSW Yellowtail Kingfish has been developed, along with a new stock assessment identifying the stock as depleted.

Harvest strategies are a best-practice way to manage fisheries. They provide a clear plan for balancing environmental, economic, social and Aboriginal cultural interests while helping to keep fish stocks healthy for future generations.

A new integrated stock assessment has estimated the NSW component of the Yellowtail Kingfish stock to be approximately 5.5% of unfished biomass. The assessment indicates the NSW stock has remained at a relatively consistent but unresponsive level over the past 2 decades.

The harvest strategy sets clear goals to rebuild the NSW stock to healthy levels. The first goal is to rebuild the stock to 30% of its unfished biomass. Over time, the aim is to rebuild the stock further to 50% of unfished biomass.

To help achieve this rebuilding goal, the harvest strategy sets initial total annual catch (fishing mortality) to 120 tonnes per year, which will be shared equally between the recreational and commercial sectors (60 tonnes each). Assessment modelling estimates rebuilding to 20% of unfished biomass in around 9 years, and 30% in around 12 years under this level of total catch.

Recent average total catches are around 250 tonnes per year. Based on current data, the following management changes would be needed to keep Yellowtail Kingfish catches at or below the target level, and within sector shares. These arrangements will be reviewed and updated before commencement and as new information becomes available.

*A recreational catch and release only season may be needed if the bag, possession and boat limits are not sufficient to reduce recreational catch to 60 tonnes for each fishing period. The duration would be assessed based on updated recreational data.

**Current data indicates a monthly limit of around 650 kg per endorsement holder to maintain catch to 60 tonnes for each fishing period. Limits will be recalculated before commencement and for each fishing period.

Lord Howe Island waters are currently excluded from the proposed management changes, recognising Yellowtail Kingfish are likely to comprise a distinct, self-recruiting component of the eastern stock.

Consultation will be open from Tuesday 1 September until Monday 15 February 2027.

Your feedback will help to finalise the harvest strategy and management actions to improve the long-term health of the NSW Yellowtail Kingfish stock. Please review the harvest strategy and FAQs for further information.

NSW consulting on Australia's first mandatory solar panel recycling scheme: Have your say

Opened: Monday September 21 2026
Closes: Monday 16 November 2026

The Minns Government is consulting on Australia's first mandatory solar panel recycling scheme to ensure valuable solar panel materials are recovered, reused and recycled rather than sent to landfill.

The proposed regulation will help drive investment and jobs in the solar recycling industry and support the potential development of a solar panel remanufacturing industry in NSW.

NSW leads the nation in solar uptake, with more than 1.18 million rooftop solar systems across homes, businesses, schools and community facilities. As these systems age, increasing numbers of solar panels are ending up in landfill.

Around 14,000 tonnes of solar panel waste is generated in NSW each year. This is predicted to increase to 89,000 tonnes by 2045.

The proposed mandatory product stewardship scheme would require solar panel brand owners to take responsibility for the end-of-life management of their products, helping fund collection, recycling and resource recovery across NSW.

Recycling solar panels is not simply about reducing waste. It is also about capturing valuable resources and creating new economic opportunities.

Valuable materials such as aluminium, glass, silicon, copper and silver can be recovered and reused in new products and manufacturing industries. As larger volumes of materials are recovered, NSW will be better placed to build local supply chains, strengthen manufacturing capability, encourage innovation and create skilled jobs across the state.

To help shape this opportunity, the NSW Government has released an issues paper alongside the draft regulation, seeking feedback on how the state can support the growth of solar panel recycling, remanufacturing and manufacturing industries.

Consultation will seek views from unions, industry, recyclers, manufacturers, researchers, local government, workers and the community on the opportunities, challenges and investment needed to build a circular economy for solar panels in NSW.

Feedback will inform the design of the mandatory product stewardship scheme with the aim of establishing a system that reduces waste, recovers valuable resources and positions NSW as a leader in solar panel recycling and circular manufacturing.

Submissions on the draft regulation and issues paper are now open. For more information and to have your say, visit /yoursay.epa.nsw.gov.au/solar.

Minister for the Environment Penny Sharpe said:

“NSW has embraced rooftop solar, and now we’re making sure those panels don’t become tomorrow’s landfill problem. Solar panels contain valuable materials that can be recovered and put back to work.

“A mandatory product stewardship scheme can help build a circular economy for solar panels, while supporting new recycling and manufacturing opportunities here in NSW.”

Public comment opens on industrial port and dredging proposal threatening Exmouth Gulf-Ningaloo

  • WA EPA has released Gascoyne Gateway’s environmental review documents for its proposed industrial port in Exmouth Gulf for public scrutiny. 
  • AMCS-Protect Ningaloo is campaigning to stop the port that would attract shipping through a critical humpback whale resting and nursing ground, require extensive dredging and cause other wide-ranging impacts.
  • Exmouth Gulf, Ningaloo will become WA’s newest marine park and is under formal assessment for National Heritage listing – AMCS-Protect Ningaloo maintains that an industrial port would be entirely incompatible with these vital conservation measures.

Australians have 12 weeks to voice their concerns about the industrialisation of Exmouth Gulf after Western Australia’s Environmental Protection Authority (EPA) today released the Environmental Review Document for Gascoyne Gateway’s port proposal for public comment. Submissions close 16 November 2026.

The Australian Marine Conservation Society states the proposal poses such widespread potential impacts to matters of national environmental significance that it has also triggered a federal assessment that will be part of this public comment period.

Gascoyne Gateway wants to build an industrial port 10km south of Exmouth town next to Qualing Pool – a rare freshwater oasis that the WA Government has earmarked as a class A nature reserve. The port would attract large vessels including fuel tankers, cargo ships, cruise liners and other heavy shipping into Exmouth Gulf, which the WA Government has earmarked for a marine park and which is under formal assessment by the Australian Government as a National Heritage treasure. 

This ecologically rich marine and coastal area is closely linked to the World Heritage-listed Ningaloo Coast and holds high conservation value. The area is home to many threatened and listed species, including dugongs, turtles, manta rays, sea snakes and dolphins, as well as corals, seagrass meadows, and sponge gardens. The proposed port would attract massive ships that would pass through a critical resting and nursing ground for one of the world’s largest humpback whale populations, posing serious threats of vessel strike and disturbance. 

Tens of thousands of people have joined AMCS-Protect Ningaloo, the Exmouth-based Cape Conservation Group and many local community members, in opposing the proposal since plans were first announced in 2020.  Over 20,000 emails have been sent to the current and past WA environment ministers calling for them to reject the proposal because it would fundamentally diminish the environmental values of Exmouth Gulf.

AMCS Chief Executive and Protect Ningaloo Director Paul Gamblin said: 

“The Gascoyne Gateway industrial port and dredging proposal is completely incompatible with the environmentally fragile Exmouth Gulf – Ningaloo’s Nursery – and would change this marine wonder forever.  

“An industrial port proposal, jutting nearly a kilometre into Exmouth Gulf and dredging of more than a million cubic metres of the seafloor in one of the world’s most important whale nursing grounds beggars belief.

“Tens of thousands of people have already made clear that industrialisation is unacceptable for Exmouth Gulf. People know that Exmouth Gulf obviously is no place for a port – its future is one of conservation and sustainable, light-touch economic activity, not industrialisation.

“Both the WA and federal governments have signalled that they are committed to protecting Exmouth Gulf so it’s time they made it clear that the future of this natural wonder is economic activity that treads lightly on its fragile environment. They must reject this proposal.

Cape Conservation Group Chair Denise Fitch said: “Exmouth Gulf is where Ningaloo’s whales rest and give birth, where our dugongs and manta rays feed. Dredging a port in the middle of this precious nursery goes against the spirit of stewardship that’s made Ningaloo the conservation and tourism success it has become. 

“Ningaloo is already under pressure from climate change. We’ve recently experienced unprecedented coral bleaching and seagrass damage from marine heatwaves, and further destruction from Cyclone Narelle. Now is not the moment to be adding industrial stressors to this fragile ecosystem. And this is no place for an industrial port. 

“We encourage those who know and love Ningaloo’s nursery to make a submission to the EPA and say no to this unwelcome proposal.”

Protect Ningaloo is calling on Gascoyne Gateway to do the right thing, as two other companies which pursued industrial projects in the Gulf have already done, and withdraw its proposal. 

Overview of Proposed Project

Gascoyne Gateway Ltd proposes to build, own and operate a multipurpose marine complex in Exmouth that will service a variety of vessels including but not limited to cruise liners and associated ecotourism activities, Defence and marine supply vessels. The project will not be utilised for livestock or iron ore.

The Proposal site is located 10 kilometres south of the Exmouth township and immediately south of the Ingram Street light industrial area; opposite the Exmouth landfill site and to the north of the Wilderness Estate residential area.

The proposal has a land-based component (including fuel storage and laydown, supporting marine facilities, desalination plant, renewables precinct, and access and utilities corridor), and a marine component (including marine infrastructure, vessel berths/channels, and anchorages).

An Environmental Review Document (ERD) has been prepared by Gascoyne Gateway Ltd in accordance with Environmental Protection Authority procedures and is released for public review.

The ERD describes the proposal, examines the likely environmental effects and the proposed environmental management procedures associated with the proposed development.

The Proposal includes a land based component (106.54 ha footprint within a 119.02 ha terrestrial development envelope) to support the marine infrastructure (61.63 ha marine footprint within and 79.44 ha marine development envelope) which includes a combination rock groyne and pylon steel construction to a berth-face. The berth face will require 13.5 m of cleared depth (at chart datum, equivalent to depth at LAT) to meet design vessel draughts, achieved by both natural depth and some dredging of sand and seabed limestone at the berth pocket. Marine construction includes piling and dredging, with dredge spoil used in the causeway construction. Three anchorage locations of 1nm diameter each are located in Exmouth Gulf approximately 9.5 km to the north east of the end of the causeway, within a nominal anchorage development envelope of 1153.14 ha. 

The ERD is available for download from Gascoyne Gateway Marine Complex | EPA Western Australia under 3. Assessment > Environmental Review.

The document is also available on the proponent’s website at Gascoyne Gateway Marine Complex.

Solar for apartment residents: Co-funding

Less than 2% of apartment buildings in NSW have solar installed, but the NSW Department of Climate Chnage, Energy, the Environment and Water are on a mission to change this.

Their Solar for Apartment Residents grant is co-funding shared solar panel installations on eligible apartment buildings and multi-unit dwellings and has already helped thousands of households.

They’ve extended the program to help more homeowners and renters reduce their energy bills and have also allocated extra funds through a separate Boost grant to help priority communities too.

Sydney Wildlife (Sydney Metropolitan Wildlife Services) Needs People for the Rescue Line

We are calling on you to help save the rescue line because the current lack of operators is seriously worrying. Look at these faces! They need you! 

Every week we have around 15 shifts either not filled or with just one operator and the busy season is around the corner. This situation impacts on the operators, MOPs, vets and the animals, because the phone line is constantly busy. Already the baby possum season is ramping up with calls for urgent assistance for these vulnerable little ones.

We have an amazing team, but they can’t answer every call in Spring and Summer if they work on their own.  Please jump in and join us – you would be welcomed with open arms!  We offer lots of training and support and you can work from the office in the Lane Cove National Park or on your home computer.

If you are not able to help do you know someone (a friend or family member perhaps) who might be interested?

Please send us a message and we will get in touch. Please send our wonderful office admin Carolyn an email at  sydneywildliferescueline@gmail.com

622kg of Rubbish Collected from Local Beaches: Adopt your local beach program

Sadly, our beaches are not as pristine as we'd all like to think they are. 

Surfrider Foundation Northern Beaches' Adopt A beach ocean conservation program is highlighting that we need to clean up our act.

Surfrider Foundation Northern Beaches' states:
''The collective action by our amazing local community at their monthly beach clean events across 9 beach locations is assisting Surfrider Foundation NB in the compilation of quantitative data on the volume, type and often source of the marine pollution occurring at each location.

Stay Safe From Mosquitoes 

NSW Health is reminding people to protect themselves from mosquitoes when they are out and about.

NSW Health states Mosquitoes in NSW can carry viruses such as Japanese encephalitis (JE), Murray Valley encephalitis (MVE), Kunjin, Ross River and Barmah Forest. The viruses may cause serious diseases with symptoms ranging from tiredness, rash, headache and sore and swollen joints to rare but severe symptoms of seizures and loss of consciousness.

A free vaccine to protect against JE infection is available to those at highest risk in NSW and people can check their eligibility at NSW Health.

People are encouraged to take actions to prevent mosquito bites and reduce the risk of acquiring a mosquito-borne virus by:
  • Applying repellent to exposed skin. Use repellents that contain DEET, picaridin, or oil of lemon eucalyptus. Check the label for reapplication times.
  • Re-applying repellent regularly, particularly after swimming. Be sure to apply sunscreen first and then apply repellent.
  • Wearing light, loose-fitting long-sleeve shirts, long pants and covered footwear and socks.
  • Avoiding going outdoors during peak mosquito times, especially at dawn and dusk.
  • Using insecticide sprays, vapour dispensing units and mosquito coils to repel mosquitoes (mosquito coils should only be used outdoors in well-ventilated areas)
  • Covering windows and doors with insect screens and checking there are no gaps.
  • Removing items that may collect water such as old tyres and empty pots from around your home to reduce the places where mosquitoes can breed.
  • Using repellents that are safe for children. Most skin repellents are safe for use on children aged three months and older. Always check the label for instructions. Protecting infants aged less than three months by using an infant carrier draped with mosquito netting, secured along the edges.
  • While camping, use a tent that has fly screens to prevent mosquitoes entering or sleep under a mosquito net.
Remember, Spray Up – Cover Up – Screen Up to protect from mosquito bite. For more information go to NSW Health.

Fox sightings, signs of fox activity, den locations and attacks on native or domestic animals can be reported into FoxScan. FoxScan is a free resource for residents, community groups, local Councils, and other land managers to record and report fox sightings and control activities. 

Our Council's Invasive species Team receives an alert when an entry is made into FoxScan.  The information in FoxScan will assist with planning fox control activities and to notify the community when and where foxes are active.



marine wildlife rescue group on the Central Coast

A new wildlife group was launched on the Central Coast on Saturday, December 10, 2022.

Marine Wildlife Rescue Central Coast (MWRCC) had its official launch at The Entrance Boat Shed at 10am.

The group comprises current and former members of ASTR, ORRCA, Sea Shepherd, Greenpeace, WIRES and Wildlife ARC, as well as vets, academics, and people from all walks of life.

Well known marine wildlife advocate and activist Cathy Gilmore is spearheading the organisation.

“We believe that it is time the Central Coast looked after its own marine wildlife, and not be under the control or directed by groups that aren’t based locally,” Gilmore said.

“We have the local knowledge and are set up to respond and help injured animals more quickly.

“This also means that donations and money fundraised will go directly into helping our local marine creatures, and not get tied up elsewhere in the state.”

The organisation plans to have rehabilitation facilities and rescue kits placed in strategic locations around the region.

MWRCC will also be in touch with Indigenous groups to learn the traditional importance of the local marine environment and its inhabitants.

“We want to work with these groups and share knowledge between us,” Gilmore said.

“This is an opportunity to help save and protect our local marine wildlife, so if you have passion and commitment, then you are more than welcome to join us.”

Marine Wildlife Rescue Central Coast has a Facebook page where you may contact members. Visit: https://www.facebook.com/profile.php?id=100076317431064


Watch out - shorebirds about

Pittwater is home to many resident and annually visiting birds. If you watch your step you won't harm any beach-nesting and estuary-nesting birds have started setting up home on our shores.

Did you know that Careel Bay and other spots throughout our area are part of the East Asian-Australasian Flyway Partnership (EAAFP)?

This flyway, and all of the stopping points along its way, are vital to ensure the survival of these Spring and Summer visitors. This is where they rest and feed on their journeys.  For example, did you know that the bar-tailed godwit flies for 239 hours for 8,108 miles from Alaska to Australia?

Not only that, Shorebirds such as endangered oystercatchers and little terns lay their eggs in shallow scraped-out nests in the sand, NSW National Parks and Wildlife Service (NPWS) Threatened Species officer Ms Katherine Howard has said.
Even our regular residents such as seagulls are currently nesting to bear young.

What can you do to help them?
Known nest sites may be indicated by fencing or signs. The whole community can help protect shorebirds by keeping out of nesting areas marked by signs or fences and only taking your dog to designated dog offleash area. 

Just remember WE are visitors to these areas. These birds LIVE there. This is their home.

Four simple steps to help keep beach-nesting birds safe:
1. Look out for bird nesting signs or fenced-off nesting areas on the beach, stay well clear of these areas and give the parent birds plenty of space.
2. Walk your dogs in designated dog-friendly areas only and always keep them on a leash over summer.
3. Stay out of nesting areas and follow all local rules.
4. Chicks are mobile and don't necessarily stay within fenced nesting areas. When you're near a nesting area, stick to the wet sand to avoid accidentally stepping on a chick.


Possums In Your Roof?: do the right thing

Possums in your roof? Please do the right thing 
On the weekend, one of our volunteers noticed a driver pull up, get out of their vehicle, open the boot, remove a trap and attempt to dump a possum on a bush track. Fortunately, our member intervened and saved the beautiful female brushtail and the baby in her pouch from certain death. 

It is illegal to relocate a trapped possum more than 150 metres from the point of capture and substantial penalties apply.  Urbanised possums are highly territorial and do not fare well in unfamiliar bushland. In fact, they may starve to death or be taken by predators.

While Sydney Wildlife Rescue does not provide a service to remove possums from your roof, we do offer this advice:

✅ Call us on (02) 9413 4300 and we will refer you to a reliable and trusted licenced contractor in the Sydney metropolitan area. For a small fee they will remove the possum, seal the entry to your roof and provide a suitable home for the possum - a box for a brushtail or drey for a ringtail.
✅ Do-it-yourself by following this advice from the Department of Planning and Environment: 

❌ Do not under any circumstances relocate a possum more than 150 metres from the capture site.
Thank you for caring and doing the right thing.

Aviaries + Possum Release Sites Needed

Pittwater Online News has interviewed Lynette Millett OAM (WIRES Northern Beaches Branch) needs more bird cages of all sizes for keeping the current huge amount of baby wildlife in care safe or 'homed' while they are healed/allowed to grow bigger to the point where they may be released back into their own home. 

If you have an aviary or large bird cage you are getting rid of or don't need anymore, please email via the link provided above. There is also a pressing need for release sites for brushtail possums - a species that is very territorial and where release into a site already lived in by one possum can result in serious problems and injury. 

If you have a decent backyard and can help out, Lyn and husband Dave can supply you with a simple drey for a nest and food for their first weeks of adjustment.

Mona Vale Dunes bushcare group: 2026 Dates

What’s Happening? Mona Vale Dunes Bushcare group catch-up. 

In 2026 our usual work mornings will be the second Saturday and third Thursday of each month. You can come to either or both. 

We are maintaining an area south of Golf Avenue. This was cleared of dense lantana, green cestrum and ground Asparagus in 2019-2020. 600 tubestock were planted in June 2021, and natural regeneration is ongoing. 

Photos: The site In November 2019, chainsaws at the ready. In July 2025, look at the difference - coastal dune vegetation instead of dense weeds. But maintenance continues and bushcarers are on the job. Can you join us?

(access to this southern of MV Dunes  - parking near Mona Vale Headland reserve, or walk from Golf Ave.) 

For comparison, see this image of MV dunes in 1969!, taken from atop the home units at the end of Golf Avenue.

Extreme El Niños are coming. Reaching net zero sooner means facing fewer of them

The world is on the cusp of an historic El Niño, a climate pattern centred in the Pacific that could reshape weather across the planet.

El Niño is hardly a new phenomenon, but forecasts indicate the coming one could be the biggest ever recorded. Research suggests extreme El Niño years will become more common as the world rapidly warms, driven by humanity’s greenhouse gas emissions.

Our new research examines the reasons why El Niño is changing, and how this climate pattern may evolve if we reach our net zero goals. Our findings suggest extreme El Niños will become more common if we remain reliant on fossil fuels, but reaching net zero earlier should limit how often they occur.

Shaping global weather

El Niño has long influenced weather across the globe by driving variations in temperature and rainfall beyond the Pacific Ocean. Here are several exceptional examples.

In 1982, a strong El Niño dumped vast volumes of rain on South America, with some rivers in Peru filled with 1,000 times more water than usual. On Kiritimati island (part of Kiribati in the central Pacific), heavy rainfall flooded seabird nests and caused entire colonies to vanish. Meanwhile, southeast Australia was crippled by drought, culminating in the Ash Wednesday fires that claimed 75 lives.

The El Niño of 1998 carried enough rain to fill a new lake three metres deep in Peru’s Sechura Desert, one of the driest places on Earth. With it came record numbers of mosquitoes and widespread malaria. In Indonesia, months of severe drought allowed devastating forest fires to burn for weeks.

In 2016, a strong El Niño coupled with already warming oceans triggered the bleaching of more than two-thirds of the Great Barrier Reef.

The current El Niño forming in the tropical Pacific is expected to be among the strongest on record, with its effects lasting well into 2027. For Australia, this could heighten the risk of hot, dry conditions and a fierce bushfire season. Its presence is already being felt across the globe, slowing the shipping of goods through the Panama Canal and forcing fish to migrate to cooler waters.

El Niño in a warmer world

Scientists have always understood El Niño to be a phenomenon that temporarily alters global weather, with conditions returning to “normal” when it dissipates. However, climate change is expected to change what “normal” looks like.

As the planet warms, extreme El Niño years are likely to become more common. Our research suggests the tropical Pacific could remain in an El Niño-like state for centuries – even if the world reaches net zero carbon emissions – and extreme El Niño years would occur more often.

We used climate models to test two possible climate futures: one in which carbon emissions continue to rise, and the other in which the world meets its net zero goals. To see if timing matters, we also examined what would happen if we curb emissions at different points during this century.

A warning from the Pacific

The Pacific Ocean covers about a third of the planet, stretching along the equator from Indonesia to South America.

Its western side is normally several degrees warmer than its eastern side. This temperature difference is linked with the trade winds that blow from east to west and pull cold water up from the deep eastern ocean. During an El Niño, this temperature gap shrinks, causing the easterly trade winds to slacken and rainfall to shift east, away from Australia.

Under continued warming, climate models show the eastern Pacific warming faster than the west, reducing this temperature difference. Scientists are yet to observe this happening, with the eastern Pacific even cooling in recent decades.

El Niño-like changes in the tropical Pacific persist long after emissions stop.

However, this warming trend is expected to emerge if the world keeps burning fossil fuels. Once it does, our findings suggest this west-to-east temperature difference will be reduced for centuries after emissions reach net zero, rather than recovering.

This is because oceans are slower to respond to warming. Research suggests global temperatures would stop rising soon after the world meets its net zero target. By contrast, ocean temperatures would keep rising for centuries.

This means the world’s oceans, particularly the Southern Ocean surrounding Antarctica, will keep warming long after emissions stop. This would draw tropical rain belts closer to the equator, as their position depends on the temperature contrast between the northern and southern hemispheres. This would keep the trade winds weak and the eastern Pacific warm.

More extreme El Niños to come

A smaller west-to-east temperature difference would mean the eastern Pacific sits closer to El Niño conditions. Heavy tropical rain needs warm water and, with the eastern Pacific projected to warm faster than the west, it would take less of a push for rainfall to shift east. This means a larger share of El Niño events would become extreme.

Our research suggests the longer we take to reach net zero, the more extreme El Niños we will likely face. Further delay could create a less hospitable climate with more risks and higher costs for generations to come.The Conversation

Australia urgently needs a national bushfire database. Here’s what it could look like

A rapidly warming world means more frequent and intense bushfires. And in Australia, the strengthening El Niño could create the conditions for fierce fires this summer.

To protect our communities, Australia must take a proactive approach to bushfire preparedness, response and recovery. But this doesn’t just depend on firefighters or equipment. Reliable, accessible and consistent data is vital to keeping communities safe.

Fire agencies across Australia are increasingly adopting new technologies that track where fires start and how they spread. However, much of this data is spread across different databases, organisations and jurisdictions, making it difficult to access when bushfires break out.

Our recent research interrogates why Australia needs a national bushfire database and maps out what it could look like.

Bushfires do not respect borders

Bushfires burn across borders, impacting countless communities far beyond where they first ignite. Australia’s current approach to collecting bushfire data fails to reflect this.

Bushfire data is recorded and managed by different organisations – including state emergency and land management services – each with their own systems, processes, standards and technical terms. With siloed databases, agencies and communities struggle to coordinate during bushfires.

During the 2019–20 Black Summer bushfires, residents on the border of two jurisdictions witnessed a devastating bushfire sweep through their communities. However, conflicting state guidelines around labelling fires meant locals couldn’t tell whether incoming warnings were about a new blaze or the one they were already watching.

The Australian government has since acknowledged just how dangerous data fragmentation can be. The 2020 Royal Commission into National Natural Disaster Arrangements and the 2020 New South Wales Independent Bushfire Inquiry both spotlighted the lack of centralised, accessible bushfire data as a major challenge. These findings have prompted initiatives such as the CSIRO’s National Bushfire Intelligence Capability.

What we studied

Our latest research makes a case for a national database, built on trustworthy, standards-based AI technologies like knowledge graphs.

To understand how such a database might work, we looked abroad. We systematically reviewed national bushfire databases, including Europe’s Forest Fire Information System. Under this system, European Union countries and neighbouring nations each collect specific types of information – including data on fire danger, burnt areas and weather forecasts – using a set of shared definitions. This allows authorities to compare fire activity and risk across national borders.

In the United States, the National Emergency Response Information System brings together data from multiple existing systems on a shared digital platform. State-based agencies – including the National Interagency Fire Center and National Weather Service – still own their information but share additional data with the national system.

These examples show national coordination doesn’t require bushfire databases to be completely centralised. Instead, it relies on interoperability – the capacity for different systems to communicate and exchange information effectively.

Technical infrastructure is key to making an Australian bushfire database work. This includes metadata that sets out rules that govern the database and a controlled vocabulary that contains a standardised list of terms and definitions. Both ensure data is collected and interpreted in a consistent way.

Barriers remain

Our research suggests data ownership, privacy, governance, funding and ongoing maintenance are among the main obstacles to establishing an Australian bushfire database.

We spoke to a range of experts from the emergency sector. They advocated for a national bushfire database, saying it would improve risk management, strengthen coordination and help agencies get resources to where they are most needed.

However, many raised data discoverability as a key concern. Vast amounts of valuable bushfire data already exist, but emergency responders may not know where to find it or who maintains it. They also expressed concerns about who would oversee the system and how responsibilities would be distributed.

Other agencies worry strict national standards could limit what practical actions they can take in local contexts. Any national system must be built on trust and collaboration between different agencies and jurisdictions. Relying on shared technology is simply not enough.

Beyond coordination, a national database could help Australia more fairly distribute bushfire management resources and facilitate the sharing of expertise, equipment and systems. Some agencies or jurisdictions may struggle to fund or develop these systems by themselves.

Local knowledge is crucial to making any national database work. Local communities can often identify at-risk landscapes and vulnerable groups that are not reflected in formal databases. First Nations peoples have used fire to care for Country over millenia. A national database informed by local and Indigenous knowledge systems would offer invaluable insights about fire behaviour, local ecosystems and cultural burning practices.

As the next bushfire season nears, the need for a national bushfire database grows ever more urgent. Collaboration and long-term federal funding are key to making it a reality.The Conversation

Wildlife populations have declined 73% since 1970 – but many of the world’s animals still aren’t being counted

Wildlife populations around the world have declined by an average of 73% since 1970. That’s according to the WWF’s new 2026 Living Planet Index – a major estimate, updated every two years, of the changing state of nature. This does not mean that 73% of the world’s animals have disappeared. Rather, it is the average decline in the size of wildlife populations that is being monitored.

The index is one of the metrics used to track progress towards the UN’s biodiversity goals and shapes narratives of biodiversity loss across the world. But the data behind that 73% headline, one of the most comprehensive available, is still far from complete.

Very few, outside of those of us working at the coalface of handling biodiversity data, understand just how poorly wild animal populations are monitored. Though the world faces the joint crises of climate change and biodiversity loss, we can track climate change through thousands of weather stations or measures of atmospheric CO₂. Biodiversity is far harder to measure. Counting wildlife is highly resource intensive, generally can’t be done from space, and systematic monitoring is extremely patchy.

What this means is that, relative to the data we do possess, there are far, far more wildlife populations that no one is counting.

Though initiatives are seeking to address this, it will be years before they will produce outcomes. And we still have the issue of historic data gaps, that is, we cannot travel back in time to count populations of the past. This means the Living Planet Index and similar efforts to track how wildlife is changing must rely on whatever data is available. These come from ad hoc academic studies, patchy monitoring programmes, and management data for harvested species.

Some critiques of the index have focused on the fact that when these records are taken at face value, roughly the same number of populations are increasing as decreasing. Similar patterns are observed in one of the other biggest collections of population change data, BioTIME.

So why does the Living Planet Index show such a strong overall decline? One reason is that the populations we have data for are not necessarily representative of wildlife populations as a whole.

The wildlife we count is not a random sample

For example, the Living Planet Index is biased towards counts from protected areas, and preliminary analysis from our team indicates both it and BioTIME contain a disproportionate number of counts in areas of mostly undisturbed habitat – such as remote wilderness or national parks.

In other words, most of the information we possess about wildlife change worldwide could be from areas where we would hope biodiversity is doing okay. This might explain the balance of declining and increasing populations in the raw data. If we don’t account for this, we risk making major underestimates of how much biodiversity is declining.

Though there do tend to be “winners” from habitat loss or change, such as farmland birds that thrive after a forest is converted to agriculture, many instances of habitat loss result in far more populations declining than increasing, like conversions of tropical forest to monoculture plantations, or grasslands to towns or cities.

But the bias could also work in the other direction. The Living Planet Index might be more likely to have data on threatened species, or on species harvested by humans (such as fish). These are all species we might expect to be declining. The truth is, we don’t fully understand all the ways in which the wildlife counts we have could be biased, or how this could affect what we know.

How scientists are trying to fill the gaps

The Living Planet Index takes steps to address bias by giving greater importance to counts from under-sampled regions such as Africa and South America.

There, the loss of undisturbed habitat is greater and there are far more species, so giving their population counts greater relative importance is a coarse way to balance some bias. It also includes data collected over very short periods – sometimes just two time points.

This sparseness comes with uncertainty about population trends, but excluding these populations would leave the index with even less data and make its underlying biases worse.

More sophisticated methods to understand bias in biodiversity science are in their infancy, and scientists are working hard to develop tools and make indicators more accurate. In the meantime, anyone interpreting the Living Planet Index must remember that the task presented to teams developing biodiversity indicators is twofold: not only to analyse existing data in rigorous ways but also to make adjustments so that the data itself is as representative as possible of the real world.

Getting this right is a phenomenally difficult task, especially for global indicators like the Living Planet Index, which have to produce a single narrative that summarises the great diversity of wildlife changes happening across the planet. As new methods emerge, scientists will work to ensure that the story told of global biodiversity loss is as accurate as possible.The Conversation

3 things we need to get right ahead of extreme bushfire risk this summer

This summer, Australia could face some of its most extreme bushfire conditions ever, due to the severity of an ever-strengthening El Niño. And for many Australians, memories of catastrophic natural disasters are still painfully fresh.

The Black Summer bushfires of 2019–20 caused destruction on a scale that had never been seen in Australia, with more than 3,000 homes destroyed. And the 2022 major floods devastated hundreds of communities across multiple states, becoming the costliest insurance event in Australian history.

While much of our disaster management approach rightly puts an emphasis on prevention, in reality that’s only part of the picture. Both these disasters left thousands displaced and in urgent need of housing as they faced the difficult task of rebuilding their homes and lives.

Our research examined their aftermath – what worked best in meeting people’s immediate housing needs and supporting longer-term housing recovery. Three key lessons emerged, calling on us to rethink our current approach now, ahead of the next disaster.

The problem with temporary villages

Our first finding is that large-scale, expensive temporary housing villages with associated infrastructure should be avoided. Despite the name, such temporary housing is rarely quick to deliver and is anything but temporary.

It can take months to procure, prepare sites for and build, and just pushes the problems to later.

Such villages were not a key feature of the Black Summer recovery. Individual housing pods were instead delivered to bushfire victims’ own properties. But temporary villages did make a costly appearance after the 2022 floods, with the construction of 11 temporary villages.

Announcing high-quality temporary housing sounds good politically after a disaster because it appears decision makers are “doing something”. But when media interest has waned, people are also left in limbo about what comes next.

What happens to people once the short time frame for their use expires? What happens to the temporary housing when councils want the land back on which it was built?

Support for alternative options

If temporary housing villages are out, what should happen immediately after people lose their homes?

The reality is that many go to live with families and friends elsewhere, while those who can afford it may move into temporary accommodation.

For those who can’t, we need to ensure safe, well-equipped temporary accommodation sites are identified in advance and ready for use immediately after a disaster.

One option is to repurpose existing caravan and holiday parks. There is also a case for relatively low-cost pods or retrofitted sheds being used, particularly where they can use existing infrastructure and allow people to remain on their own land while rebuilding.

Prioritising community needs

While these are measures for meeting immediate basic needs, what can be put in place for helping people recover in the long term?

Although recovery is a large and complex subject, the second clear lesson from our research is the importance of prioritising community-centred recovery. Providing coordinated support from assisting organisations is one part of this.

The NSW Reconstruction Authority’s Recovery Centres, for example, seek to bring services together so people do not have to navigate multiple organisations independently.

Another is recognising the central role of local community organisations and ensuring they have the support and resources to assist. Local councils are also often expected to shoulder a significant recovery workload, but with limited resources.

State and federal governments need to support this more seriously and ensure local government has the capacity, funding and authority it needs to play its role effectively.

Different communities have different needs

The third lesson from our research is that communities are also anything but homogeneous. The proportion of renters to homeowners is one such divide.

Affected homeowners with insurance policies need speedy insurance support. The cost of insurance is, however, skyrocketing – or for some, becoming unavailable – and government needs to work with insurers to address this increasing problem.

Many others rent their properties, adding landlords to the complexity of recovery. Cash assistance is one way to give renters some ability to exercise agency in recovery (as it does for homeowners also). Global evidence of providing cash grants after disaster as helpful, efficient and effective is overwhelming.

All this can sound relatively straightforward on paper. The reality, of course, is that a disaster has occurred, and recovery takes time. Add trauma, family breakdown and loss to the equation.

Housing recovery needs to recognise these realities. Support should be flexible, sustained and responsive rather than dictated through top-down solutions without proper and realistic consultation, as all too often happens.

An opportunity to prepare now

Held every year on October 13, the United Nations’ International Day for Disaster Risk Reduction aims to raise disaster risk awareness, reduction and preparedness. This year’s theme focuses on resilience in the home.

In Australia, with the frequency and scale of disaster set to increase, this calls on us to take recovery planning as seriously as we take preparing for the immediate emergency.

If we want to “build back better”, “better” means learning from the previous disaster, taking preparedness seriously and putting affected communities at the centre of all decisions.The Conversation

How electric vehicles could help pollinators find flowers again

James Ryalls, University of Reading

A hidden threat is making it harder for bees, butterflies and other pollinators to do their job: air pollution is scrambling the floral scents they use to find flowers.

Colleagues and I have just published research showing that ground-level ozone and nitrogen oxides (two pollutants strongly linked to fossil fuel use) significantly impair pollinators’ ability to locate and feed from flowers.

The good news? The global shift away from fossil fuels, including the rise of electric vehicles, could eventually ease this pressure. But timing matters. Things may get worse before they get better.

Flowers release complex cocktails of volatile organic compounds, essentially their perfume, to attract pollinators. These scents act like a GPS for bees and other insects.

But when ozone and nitrogen oxides (NOx) react with these compounds, they break down or alter the chemical signals. The result is that pollinators struggle to find the flowers they need.

This isn’t just a problem for wild plants. Almonds, apples, oilseed rape, strawberries and many other important crops depend on insect pollination. When pollinators can’t forage efficiently, yields and quality can suffer.

What the evidence shows

We analysed 22 experimental studies, mostly from Europe, that tested how elevated levels of ozone and NOx affect pollinators’ ability to find and feed from flowers, as well as their overall abundance.

On average across the studies, elevated ozone reduced pollinator performance by 42%, while NOx reduced it by 46%. When the two pollutants occurred together (as they do in the real world), the average reduction was 68%.

However, only a small number of studies tested the pollutants both separately and in combination. In those comparisons, the additional impact of combining the two pollutants was relatively modest.

Pollinators’ searching efficiency – the ability to locate flowers – was hit hardest, dropping by 67% on average. Feeding efficiency and overall abundance were less affected.

This suggests the main problem with the pollution is that it disrupts pollinators’ ability to find flowers, rather than being directly toxic to the insects themselves.

The coming ozone peak – and why it happens

There is a complication, however. NOx and ground-level ozone are linked chemically, so cutting NOx emissions will not necessarily reduce ozone immediately. In fact, under a middle-of-the-road emissions scenario, global low-level ozone levels are projected to keep rising until around 2050, even as NOx emissions begin to fall.

This is partly because ozone and NOx interact in the atmosphere. NOx can react with and destroy ozone. When NOx levels are high, as they often are near roads or in cities, this “quenching” effect helps keep ozone concentrations down.

So, as we cut NOx emissions from diesel vehicles and other sources, this quenching effect weakens. With less NOx around to break it down, ozone concentrations can actually climb. Other ozone-forming pollutants, such as methane, also remain high for longer in this scenario.

Only after this mid-century peak do sustained reductions in NOx and other precursors drive ozone levels down again. Under this middle-of-the-road scenario, ozone is projected to fall back below present-day levels after 2050. Faster decarbonisation would bring that recovery sooner.

Why diesel emissions matter

Diesel vehicles, especially heavy-duty trucks and agricultural machinery, are among the largest sources of NOx emissions.

In many regions, heavy-duty diesel vehicles alone account for more than 70% of on-road NOx. These emissions not only directly harm pollinators. Through their effects on ozone, they also alter the chemical environment around flowers.

Electric vehicles produce zero tailpipe NOx. Replacing diesel vehicles with electric alternatives, particularly in freight, construction and farming, would cut an important source of NOx and, over time, help reduce the ozone pollution that interferes with floral scents. The benefits would be even greater as electricity generation becomes cleaner.

Our analysis shows that the rate of pollinator recovery will depend heavily on how quickly we reduce these emissions. Delaying the phase-out of diesel vehicles would prolong the mid-century ozone peak and delay the ecological recovery we all need.

What needs to happen now

Protecting pollinators should be considered a co-benefit of clean air and climate policy. Accelerating the transition from diesel to zero-emission vehicles, especially in heavy-duty and agricultural sectors where diesel remains important, would reduce a major source of NOx.

We also need better monitoring and research. Our evidence mostly comes from European studies on bees and a few other pollinator groups. We urgently need more research in high-pollution, biodiversity-rich regions, and on a wider range of pollinators including moths, flies and beetles.

The timing and location of pollution reductions could also matter. Measures that reduce exposure during peak flowering, for example, could help limit the disruption to pollinators before longer-term reductions in ozone kick in.

The fossil fuel transition is not just about carbon and climate. It is also about restoring the chemical cues that pollinators depend on as they search for flowers.

If we move quickly enough, we can shorten the difficult mid-century period and give bees, butterflies and the crops they support a genuine chance to recover.

The science is clear: cleaner air means healthier pollinators and more resilient food systems. Electric vehicles are one powerful tool in that toolkit. The sooner we deploy them at scale, the better the outlook for the insects that help feed us all.The Conversation

Are Australia’s native bees thriving or declining? We don’t know but can find out

It’s a sight to behold.

Each spring, thousands of solitary bees (Amegilla dawsoni), also known as Dawson’s burrowing bees, emerge from burrows scattered across Western Australia’s arid plains.

These bees, distinguished by their fluffy appearance and either white and maroon (females) or coffee (males) colouring, are on a quest to find flowers and a mate. They are just one of more than 1,700 native bee species that call Australia home – a figure steadily rising each year.

Tragically, Australia’s native bees face a conservation crisis. Wild bees are declining worldwide, under pressure from habitat destruction, invasive species, pesticide use and climate change. Due to a lack of funding and attention, few people recognise how much native bees are struggling. Even native bee researchers don’t have all the answers.

Our new study took a closer look at the major threats to Australia’s native bees and, by drawing on research from here and abroad, created a plan to conserve them.

Why wild bees matter

Native bees play an indispensable role in ecosystems across Australia.

They pollinate many native plants that can’t be pollinated by introduced species, including valuable crops such as macadamias and mangoes. Native bees provide vital food and habitat for an array of Australian animals, including by pollinating eucalypts that feed koalas. In doing so, they help entire ecosystems thrive.

For First Nations communities, native stingless bees also hold significant cultural value. For thousands of years, First Nations peoples have used stingless bee honey and wax in gifts, food, and the making of tools. These bees also feature in many traditional stories such as The First Bees, an oral history from the Gunwinggu people of West Arnhem Land about ancient beings turning into stingless bees.

Neglected for too long

In Australia, scientists are discovering more native bee species each year, with more than 115 new species described last year. Examples include the devilish Megachile lucifer and 71 species of resin pot bees from the genus Megachile. Australia is also home to some of the tiniest bees in the world, including the miniscule Euryglossina clypearis, which grows to just 1.8 millimetres long.

However, conservation research is not keeping up. An influential paper from 2009 examined both the diversity of Australia’s native bees and the challenges they face. These include land clearing, disease, and competition with introduced plants and bees. But climate change and habitat loss remain the most pressing threats.

Since that study, research and funding for native bee conservation has been scarce. This lack of resources may be because few people recognise how important native bees are for keeping humans and ecosystems healthy.

While some native bees are crop pollinators, such as the buzz-pollinating Amegilla, many are not. Bees that do not pollinate crops typically attract less attention than other well known pollinator species, such as the introduced European honeybee (Apis mellifera).

However, bees that don’t pollinate popular food crops actually need the most help.

What needs to change

To better protect our native bees, Australia must accurately identify how many species are on the brink of extinction. Only three native bee species are listed on Australia’s national threatened species list, compared to six different native species identified by the global International Union for Conservation of Nature (IUCN) Red List.

Based on how much bee habitat was destroyed during the 2019–20 Black Summer bushfires, 11 more species should sit on Australia’s threatened species list. However, listing requires us to have enough data on a species’ size and distribution, as well as a recognised scientific name. For many native bees we simply don’t have this information, so more research is urgently needed.

We must also invest in studies into native bee behaviour, such as how bees navigate, search for flowers, and identify their favourite plants. This information will help us understand how bees will cope with environmental threats such as climate change, and find ways to support them.

More research into native bee behaviour is urgently needed. Kit Prendergast

This increased knowledge will form the basis of conservation plans. Short-term plans may focus on regulating the use of pesticides that harm bees, or protecting native bushland. Long-term plans may rely on ongoing monitoring programs that bring together researchers, farmers, and community members. As bee researchers, we are also working on an Australian Native Bee and Pollinator Conservation Strategy with evidence-based guidance for everyone from landowners to local councils.

Community members can also spread the word about native bees. You could invite scientists to speak at your school, sport club, or community group. You can learn about flowering plants that support native bees in your local area by visiting council websites or reading books dedicated to Australia’s native bees. You may also make your backyard or garden more native bee friendly by building bee hotels, leaving bare ground for burrowing bees to nest in, or filling pots with rock gravel for nesting bees.The Conversation

The joy of song: where songbirds came from and why we should listen to them

Hollis Taylor, University of Sydney

In 2001, I had an epiphany while making my first trip to Australia.

Walking across a remote sheep station in the dusty west, my ears were suddenly filled with the rich, spirited song of three pied butcherbirds.

Together, their voices wafted through the air like a hauntingly beautiful flute. That was the first time I encountered a trio of singing birds. I was instantly captivated.

Almost three decades later, I’ve built a career as a musician, composer and zoomusicologist – someone who studies sound in animal culture.

That serendipitous experience sparked my quest to understand how songbirds shape sound and why birdsong affects us so deeply.

The origins of songbirds

There are at least 4,000 species of songbirds, also known as oscine passerine birds, which together make up nearly half of the world’s bird life. This includes familiar and much-loved species like lyrebirds, fairywrens and honeyeaters.

Birdsong research has long focused on the northern hemisphere. However, DNA evidence from a major 2002 study turned this upside down. It revealed that all songbirds originated in Australia, before spreading across the world. Tim Low’s best-selling book, Where Song Began (2017), did much to popularise this research.

Subsequent studies refined this picture, suggesting early songbirds radiated out from Gondwana – the ancient supercontinent that included Australia, Antarctica and South America. The well-known lyrebird and the rare, ground-dwelling scrub-bird are thought to be the Australian songbirds with the oldest lineage.

Today, songbird hotspots are scattered across the globe.

South and Central America – particularly Colombia, Peru and Costa Rica – are famed for their avian diversity. New Guinea is home to birds-of-paradise, whose strikingly colourful displays have fascinated scientists and artists alike.

Europe’s spring chorus – sustained by blackbirds, thrushes and nightingales – features widely in literature and film. And in North America, birders prize the flutey flourishes of the hermit thrush and the wood thrush’s bell-like notes.

Learning to sing

These melody-making birds share a rare gift: they learn their songs from parents and peers. This process is known as vocal learning.

Among birds, only parrots, hummingbirds and songbirds are vocal learners. Humans are the sole primate that falls into this category, capable of imitating, altering and learning from the sounds we hear. Elephants, whales and some bats are also vocal learners.

Birdsong is often framed as a tool males use to compete for a territory or a female’s attention. Birdsong does serve these two practical functions. However, some birds produce sounds infinitely more beautiful and complex than what’s strictly needed to retain a territory or attract a mate.

It’s worth noting songs are not the same as calls. While birds must learn to sing, they have a relatively innate ability to call. Calls are short, meaningful sounds that help birds do everything from feeding to nesting and flocking, where birds gather to collectively forage or travel.

Wood thrushes can often be heard in the forests of the southeastern United States.

How birdsong affects us

Many people turn to birdsong as a way to relax and reconnect with nature. But listening to birdsong isn’t just pleasurable.

Research suggests it can reduce stress, improve anxiety and even sharpen attention. One 2022 study suggests listening to birdsong for just six minutes improves mental wellbeing. Another 2021 review found that when people tuned into natural soundscapes – such as birdsong or the sound of fast-flowing water – their blood pressure and heart rate lowered.

Many people instinctively know this. Consider how often birdsong features in meditation apps, in films or even at shopping centres.

Hearing a wild bird’s song is both ordinary and majestic. Ordinary because songbirds aren’t usually surrounded by sweeping vistas – instead they may be perched on a power line or hidden high in a tree. It’s also majestic because people are often deeply moved by these encounters. A single song can lift the mood of a morning.

Where to listen

Thankfully, you don’t need to traverse the world to tune into birdsong.

Australia is rich in birdwatching opportunities, particularly in the north and east of the country. If you’re unsure where to go, you can visit Australian Geographic’s top birding locations website. You can also find songbird hotspots in Australia and abroad using Birdingplaces’ interactive global map.

You don’t even need a car. Dawn is when birds are most active, so you may encounter a songbird if you step out early. It also pays to walk near water, where vegetation is dense and insects plentiful. But many avian singers also thrive in suburbs and urban parks.

Once you start hearing and observing birds, you will inevitably want to identify them. An abundance of online tools can help. A free option is eBird, which allows birders of all stripes to identify and document species. Xeno Canto is another resource.

You don’t need to identify a bird to enjoy its contribution to the dawn chorus. Just slowing down and listening is a good start.The Conversation

Colonisation, not climate change, first primed these forests to burn

Bushfire season is here. The Bureau of Meteorology expects the declared El Niño to be strong to very strong. Southeastern Australia is bracing for a long run of dangerous fire weather.

Weather is only part of a catastrophic fire. Another factor is fuel – combustible vegetation. Our new research, published today, shows the current fuel load in some Australian forests is not “natural”. It is a product of colonisation, which loaded Australian landscapes with fuel a century before human-made climate change began.

Consider Croajingolong National Park, in Victoria’s far east. It has every level of protection possible: national park, designated wilderness area and UNESCO Biosphere Reserve. It’s also one of the most repeatedly incinerated forests in Australia: the 2019–20 Black Summer fires alone burned through 90% of the park.

The reprieves between bushfire have collapsed, from roughly 40 years in the late 1800s to about five years in the most recent decade.

Reading a natural archive

We conducted this research in partnership with the Gunaikurnai Land and Waters Aboriginal Corporation, coauthors of the study, on GunaiKurnai Country in the Croajingolong National Park, which takes its name from the Krauatungalung people of the GunaiKurnai.

Our archive is Purghagoolah, called Lake Elusive by colonial mapmakers, a deep lake inside the park. Our data were pollen, charcoal and sediment.

In February 2021 we took a core sample – a cylindrical piece of layered sediment – from its depths to retrieve evidence of a 1,000-year history. The pollen and charcoal within the sediment, blown in from the surrounding 10,000 square kilometres, offer records of a vast slice of Australia’s most frequently burnt forests.

Pollen reveals what grew, charcoal tells us about fire, and the infrared spectra of this charcoal reveals how hot these fires were. This allows us to separate cooler cultural fire – where low-intensity fires were strategically applied to the landscape – from hot wildfire. In addition, magnetic minerals track erosion of soil into the lake, and radiocarbon and lead dating anchor this history in time.

Before and after

We found that for more than 800 years, frequent, low-temperature cultural burning under GunaiKurnai care held this land as stable, open woodland. In this period, the landscape was low in charcoal, rarely scorched by hot fires, and without the erosion that follows.

There was no lack of dangerous fire weather in the past. Fire seasons as severe as Ash Wednesday, Black Saturday and Black Summer occurred over these centuries, yet cared-for Country did not experience catastrophic fire.

However, during the colonisation of Gippsland, frontier violence and massacres between the 1830s and 1860s removed GunaiKurnai people from Country and disrupted a millennia-long relationship of care.

After colonisation, everything in the sediment core changes. Hot fire becomes dominant, shrubs thicken, eucalypt cover surges to nearly four times pre-colonial levels, and open woodland becomes today’s flammable forest. Charcoal rises sharply, alongside an increase in hot fires. Soil washes into the lake, no longer bound by living plants.

All this took place before human-driven climate change properly began, echoing what we found across southeast Australia in a 2022 study: a region-wide increase of shrubs following the British invasion.

The outcome is a catastrophic wildfire loop: each hot fire drives thick, flammable regrowth that primes the next climate-driven fire. Climate change did not start this vulnerability – it amplifies one that colonisation began.

A wilderness that colonisation built

All this, in a place we protect as pristine wilderness. Official vegetation maps treat Croajingolong’s forests as the natural, pre-colonial baseline state. But our data demonstrates otherwise – the wilderness we protect is one colonisation made. Management relying on that false baseline entrenches fire danger, and ignores the ecological and cultural relationships held within the now-lost woodlands.

Aboriginal people have long said it plainly: wild Country is sick Country, Country that has lost its people and their care.

GunaiKurnai ancestors were born with towera (fire), an essential part of the old peoples’ practical daily life on Country, as GunaiKurnai Elder and study coauthor Uncle Russell Mullett says:

Not treating country with towera, Country becomes extremely dangerous for GunaiKurnai, animals, and plants. Studies such as this provide firm scientific evidence to support towera land management initiatives for Country.

A region-wide transformation

The waters of Purghagoolah sit within roughly 3 million to 4 million hectares of forest that runs unbroken from the Victorian Central Highlands to the New South Wales south coast. Around 80% of it is resprouting eucalypt forest, that could benefit from regular cooler cultural burns.

The rest of these forests, around 20%, is the fire-sensitive mountain and alpine ash forest of the valleys and high country. They have a fundamentally different fire ecology that requires hot fire to release and germinate seeds separated by long fire-free intervals. Yet these atypical, less extensive forests dominate public discourse and fire policy. This fosters an ethos of fire suppression that increases risk across vast forest areas.

Bring back the carers

None of this diminishes the threat of climate change. Rather, our research emphasises the parts of the story that have been historically overlooked: the fuel, and the care by people who once kept it in check.

Fire management must grow beyond hazard-reduction burning and climate adaptation into restoring healthy Country and cultural burning, with Traditional Owners resourced to lead the way. Cultural burning reduces catastrophic fires, is better for the soil, and protects our plants and animals.

Purghagoolah leaves us with hope. Through at least eight centuries of severe fire weather, fire stayed in human hands and catastrophic fire was contained. Country needs people. When Country is cared for, climate is not the only factor that dictates how it burns.The Conversation

One giant clam contains a month‑by‑month diary of the Great Barrier Reef’s climate 200 years ago

When you swim through the azure waters of the Great Barrier Reef, there is one entity on the seafloor that’s almost impossible to miss: the giant clam. Its huge, fluted shell frames a soft mantle shimmering with electric blue, green and gold.

As the world’s largest living bivalve, Tridacna gigas can reach 1.2 metres, weigh more than 200 kilograms and live for over a century. Across their long lives, these clams record their daily life in their shells, creating an autobiographical shell diary.

In our new research, we read one of these shell diaries to reconstruct month-by-month climate conditions at Jiigurru (also known as the Lizard Island Group), in the northern Great Barrier Reef.

The shell’s story reveals that, before widespread industrial-era warming, Jiigurru’s summers were cooler than today, while winters were surprisingly similar.

How can a shell keep a diary?

As a giant clam grows, the cycle of day and night produces microscopic daily lines in its shell, while the changing seasons produce broader annual bands. Like tree rings, these layers turn the shell into a diary.

The growth lines provide the dates, just as we date entries in our own diaries. The surrounding seawater writes the content by shaping the chemistry of each new layer.

Geochemistry is the language in which this climate diary is written. By reading that language, climate researchers can decode how the reef environment changed during the clam’s long lifetime.

The missing southern record

Today, instruments on land, in the oceans and in space constantly measure the changing climate around the world. But these direct observations cover only a small slice of Earth’s history. To look further back, researchers need to turn to other climate archives: records preserved in tree rings, corals, ice cores, lake and ocean sediments, and shells.

Yet many of the most detailed records before industrial-era warming come from the Northern Hemisphere and from high latitudes. Tropical oceans in the Southern Hemisphere are much less well documented.

Giant clams live across the tropical Indo-Pacific. Their shells can add local, sub-seasonal resolution records to this missing southern story.

Reading the shell

Our study was done in partnership with the Walmbaar Aboriginal Corporation and Nguurruumungu Indigenous Corporation. Published in the journal Global and Planetary Change, it focused on a 58-centimetre giant clam shell collected from the lagoon at Jiigurru.

Jiigurru is a culturally important place for Dingaal and Ngurrumungu Aboriginal communities. Archaeological excavations at shell midden sites show at least 6,500 years of Aboriginal occupation.

Radiocarbon dating showed the clam lived between about 1785 and 1827, near the end of a pre-industrial cooling period known as the Little Ice Age. Under a microscope, we counted almost 10,900 daily growth lines, showing it lived for about 30 years.

We then drilled 784 tiny holes to take powder samples from shell layers. In each sample, we measured different forms of oxygen and carbon, called isotopes.

The oxygen isotopes helped us estimate past sea temperatures. The carbon isotopes gave us clues about rainfall. Matching these chemical clues to the shell’s growth structure gave us a month-by-month picture of the reef environment prior to industrial warming.

What the shell revealed

Compared with sea surface temperatures measured in the same lagoon from 1995 to 2015, our reconstruction showed that 225 years ago temperatures were 0.6–0.9°C cooler on average across the year. Summers were 0.9–1.2°C cooler, but winter temperatures were almost the same.

The shell diary told us more than just temperature.

Its carbon isotopes traced a clear rhythm between wetter and drier seasons. The temperature record also rose and fell in repeated two- to three-year cycles, consistent with local El Niño-like and La Niña-like variability.

The clam revealed that El Niño-like episodes (warmer, drier) were more common near the end of the 1700s. In the early 1800s, La Niña-like conditions (cooler, wetter) became more frequent and included the strongest events in the record.

A single average would miss all this detail. The month-by-month record shows how temperature changed through the seasons, how wet and dry conditions alternated through the year, and how climate shifted from one year to the next.

A wider Southern Hemisphere picture

Was Jiigurru an isolated case? Other records suggest not.

Corals from elsewhere on the Great Barrier Reef and north-western Australia also point to cooler seas or changes in ocean conditions.

Antarctic ice and glacier records show cooling and shifts in circulation around the same period.

Farther afield, other records point to La Niña-like conditions. Galápagos corals show frequent La Niña events during the early 1800s. Cave records from northern Peru indicate wetter Little Ice Age conditions. Lakes in south-eastern Australia were also higher in the early 1800s.

Seen together, these archives sketch a wider Southern Hemisphere story. Many places were cooler, while rainfall and ocean circulation shifted in different ways. But this was not one uniform event. The cooling at Jiigurru was smaller than many Northern Hemisphere estimates, showing why local records matter.

Our giant clam adds a rare month-by-month marine chapter to this broader Southern Hemisphere climate story. Similar shells from other Indo-Pacific reefs could show how these wider climate changes unfolded from place to place. Many more climate diaries may still be waiting inside giant clam shells.The Conversation

Over 40 years ago, a mystery vigilante released a fungus to control blackberry in Australia. But why?

Simon Farley, The University of Melbourne

Over the summer of 1983–84, a fungus called Phragmidium violaceum was introduced to Australia. It was done secretly, deliberately and illegally. And it was done for one purpose: to kill blackberry plants.

I’m a historian, not a detective. My recent research on the illicit introduction of violaceum (also known as ‘blackberry rust’) doesn’t identify a culprit. But it does shed light on one of Australia’s most significant and mysterious breaches of biosecurity over the past half-century.

Like so many other animals and plants, blackberry was deliberately introduced to Australia from Britain. The earliest records date to the 1840s. The plant was valued for its abundance of juicy fruit as well for its uses as a hedge. Few herbivores other than tough-lipped deer and goats can eat the thorny plant. But its delicious berries are prized by all sorts of animals, from foxes to fairywrens.

Every Australian knows common mynah birds are bad, rabbits are worse and feral cats kill native animals unchecked.

But how do we decide what makes an introduced species “good” or “bad” – and will we ever concede that some species are here to stay?


With the help of humans and animals, blackberry spread rapidly. By the late 1880s, it was becoming recognised as a serious agricultural weed. Unchecked, it forms dense, thorny thickets which are hard to reclaim as farmland.

When official control efforts began in the 1890s, they had little effect on the tough plant. But agricultural scientists were determined to find a solution – even if it took decades.

From cactus moths to blackberry rust

In the inter-war period, Australian scientists found a neat remedy to a far worse weed – prickly pear, an introduced cactus carpeting vast areas of pasture in New South Wales and Queensland.

In the mid-1920s, the Commonwealth Prickly Pear Board introduced the Cactoblastis moth from Argentina. These moths could kill the cactus while leaving native species untouched. By 1933, it was reported in the journal Nature 80% of the prickly pear “infesting” Queensland and 50-60% in NSW had been “destroyed”.

Cactoblastis is an example of biological control – when humans introduce a predator, parasite or pathogen in order to eradicate a pest. Think of it as weaponising ecology for human ends.

From the late 1960s, scientists at Victoria’s Keith Turnbull Research Institute began investigating blackberry rust as an agent of biological control. The fungus does not kill blackberry plants, but it does slow growth and reproduction.

In the early 1980s, the Institute sent one of their top scientists, Eligio Bruzzese, to a CSIRO laboratory in France to test the fungus. His experiments seemed to show the rust would work well and would not threaten more valued plants. He returned to Australia in early 1983.

But the Institute never got a chance to release the rust. In February 1984, the violaceum fungus was unexpectedly found on blackberry plants near Yarram in south-eastern Victoria.

Within days, more cases of rust were spotted over 100km away on blackberry plants growing in the Dandenong Ranges and in Melbourne’s eastern suburbs.

Science journalist Graeme O’Neill wrote in The Bulletin that the evidence indicated:

somebody visited Europe – probably France – and picked some leaves from rust-affected blackberries, returned with them… and dusted the fungal spores onto the leaves of blackberries […] Department of Agriculture officers actually located that first plant and noted the regular spacing between [other infected] plants

Had someone been prosecuted, they could have been punished with a A$100,000 fine or five years in prison. This was a crime with surprisingly high stakes.

There’s no suggestion Bruzzese was involved. In public statements, the frustrated scientist claimed the strains of violaceum he had hoped to introduce would have been far more effective.

That same year, federal parliament passed laws making it easier for scientists to research biological control.

When the Minister for Primary Industry, John Kerin, spoke in favour of the bill, he referenced the illegal introduction of violaceum as evidence of the need for more transparent regulation.

In 1991, authorities bowed to the inevitable and began releasing further strains of blackberry rust. Despite the controversy, the fungus only had a mild effect on blackberry. Authorities still rely on poison and manual control.

Why was it done?

It may be hard to understand how the humble blackberry could inspire someone to go to such extremes.

Sure, blackberry can be obnoxious from a human perspective. Even with the fungus circulating, the plant remains a nuisance for farmers. It’s listed as a Weed of National Significance. In 2017, authorities estimated it was costing Australia over $100 million annually across production losses and the expenses of “controlling” it.

But many species, introduced and native alike, cause headaches for farmers and other land managers. Not all of them provoke such dramatic responses.

In 1984, authorities assumed a disgruntled farmer was responsible. But this isn’t certain.

Blackberry affects all sorts of people. The plant’s thorns are a persistent nuisance to bushwalkers, cyclists and horseriders. Rampant blackberry blocks off paths and watercourses. It has been deemed an environmental weed, too, although it also provides important food and habitat for native animals such as bandicoots.

In short, there were many reasons why someone might have done it.

Seeing the other side of blackberry

Unlike many weeds, blackberry also has its defenders. Through the 1980s and ‘90s, news stories about violaceum prompted some Australians to write of their fondness for blackberry. Blackberry wasn’t just a British or European plant anymore. Many Australians now had their own cherished memories of picking berries.

Blackberry has now been in Australia close to 200 years. It has become naturalised and – to a degree – normalised.

Unless scientists discover a much more effective method of biological control, it’s probably here to stay. That will mean more valuable pasture lost and more nasty scratches for bushwalkers. But it will also mean more habitat for urban bandicoots and more delicious fruit for the adventurous.

The good might not outweigh the bad, but for the time being, we may have to learn to be more accepting of blackberry where we can.

This whodunnit may never be solved. But the case of the blackberry rust reminds us that weeds – and our responses to them – can be more complicated than they first appear.The Conversation

Cities across the world are sinking because of groundwater depletion. But the process can be reversed

Many cities around the world are sinking because too much water is extracted from the groundwater reservoirs beneath them.

This sinking makes these coastal cities more exposed to rising seas as the climate warms.

But as our new research shows, this process can work in reverse; when groundwater is replenished, cities can rise.

Our findings also reveal an unexpected clue: faultlines play a key role in shaping where the fastest groundwater recovery and land uplift occur.

The global problem of sinking cities

Land subsidence, the gradual sinking of the ground surface, affects many of the world’s major cities.

Parts of Jakarta, the capital of Indonesia, are sinking more than ten centimetres each year, prompting the government to plan a relocation of the city.

The coastal city of Tianjin, China, is home to 15 million people. It, too, is a subsidence hotspot. If sinking there continues unabated, 15% of the city’s population will be underwater by 2120.

Similar stories are playing out from San Diego to Iran’s major cities, wherever groundwater has been pumped faster than it can refill.

In Aotearoa New Zealand, recent studies show around 80% of the urban coastline is sinking, and that groundwater may be a contributing factor in some areas, including Christchurch and Wellington.

How urban groundwater leads to sinking

Many cities are built above natural groundwater reservoirs (aquifers), and are literally held up, in part, by the water beneath them.

Think of a gigantic water balloon beneath a city. The balloon represents an aquifer full of water. When groundwater is pumped out, the “balloon” deflates, and the ground above sinks.

This matters most at the coast. If the land is sinking while the sea is rising, the two effects combine, meaning coastal cities experience relatively higher sea levels, and the impacts of climate change arrive sooner.

This effect of groundwater pumping on land subsidence is well understood, and improved groundwater management is often put forward as the key strategy for slowing or halting the sinking.

What is not clear is how the ground beneath a city responds when long-term water aquifer recovery happens. Does the ground simply rise back up, uniformly, like a balloon reinflating? Or is the response more complicated?

To answer this, we need two key things: long-term records of where the water is accumulating in the underground aquifers, and precise millimetre-scale measurements of elevation of the ground surface above.

Osaka, a natural laboratory

Osaka provided the perfect setting to explore this. Between the 1920s and 1960s, heavy groundwater pumping lowered water levels beneath the city by up to 30 metres, and the land sank by more than two metres in places.

This led the Japanese government to introduce strict groundwater regulations in the early 1960s. In the decades since, groundwater levels have been recovering steadily.

To track the groundwater levels, we looked at data from 44 monitoring wells, some reaching as deep as 500 metres below the surface, and stretching back in time to 1985.

To measure the tiny changes in ground elevation, we used a technique known as interferometric synthetic aperture radar (InSAR). This involves the repeat acquisition of satellite radar images of the Earth’s surface, tied to very accurate global navigation satellite system measurements of ground stations.

The results are striking. Across greater Osaka, home to about 15 million people, the ground is rising, and fast.

The speed of uplift averaged about four millimetres a year, and was as high as 12 millimetres a year in some places. Groundwater levels have also been steadily rising, at rates of up to a metre a year. Where water levels climbed fastest, so did the land.

But the map of uplift was also very patchy.

One city block could be uplifting fast, while less than 100 metres down the road it could be much slower. These abrupt changes aren’t random. They form narrow but continuous corridors that ran across the city.

We soon realised something unexpected: these corridors mapped almost perfectly onto known tectonic fault lines.

Faults act like dams

Faults are fractures in the Earth’s crust, and are usually thought of in terms of earthquakes. But we found they play another role here.

Picture a fault as a curtain hanging vertically underground, cutting through the aquifer. Instead of holding back light, it holds back water, blocking its sideways flow and acting like an underground dam.

On one side of Osaka’s Uemachi Fault, groundwater levels have been rising three times faster than on the other side.

We found the same pattern repeats at other faults across the city. Water dams on the “upstream” side of a fault, where it can’t easily flow through, driving faster groundwater recovery and faster uplift there, while the “downstream” side lags behind.

Our research highlights a potentially important opportunity for coastal cities adapting to sea-level rise.

Where groundwater depletion has contributed to land subsidence, reducing extraction and allowing aquifers to recover could reduce – and in some places potentially reverse – the downward movement of the land.

As seas continue to rise, keeping the ground beneath coastal cities from sinking could be an increasingly important part of adapting to a warming world.The Conversation

‘We will not be sacrificed’: Pacific climate voices were clear and strong this week – and we’re listening

Preparatory meetings for the United Nations’ annual climate summit are usually quiet affairs, focused on laying the political and technical groundwork for the main COP event. But this year felt very different.

I was at this week’s pre-COP31 gathering in Fiji for talks that were both harmonious and powerful. Pacific delegates were clearly frustrated at having to repeatedly retell their stories of climate change. But they were also generous in their wish for the world to engage with the reality they face.

Following a tussle for leadership last year, it was agreed Australia would jointly host these Pacific climate meetings with Fiji. Rival bidder Turkey (also called Türkiye) will host the annual UN COP31 climate summit in the city of Antalya in November.

There has been criticism of the number of world leaders at the A$20 million Fiji meeting – with 14 national leaders making a side visit to Tuvalu on Tuesday, and just two of those hailing from outside the Pacific.

However, the purpose of meeting was not a leadership summit – although more national leaders attended than in previous years.

Rather, it was a chance for governments, community leaders and Australia’s Minister for Climate and Energy Chris Bowen – who has the role of president of negotiations at COP31 – to hear directly from Pacific leaders, ministers and climate envoys on their priorities.

And they had so much to say.

The Pacific should not be sacrificed

The most obvious shift in Fiji was the difference in tone. Pacific voices, music, art, film, tradition and storytelling took centre stage. It reminded everyone that if these parts of the world are lost to climate change, so, too, is their inextricably intertwined culture.

There was unabashed honesty about the emotional, psychological and cultural toll climate change is taking, which undeniably moved all those who attended. More than a few tears were shed.

Over the course of the four days, the clear sentiment in meetings was the frustration Pacific delegates felt at having to tell – and re-tell – their stories about the risks and damage caused by climate change.

There was a sense the Pacific has been relegated to a “sacrifice zone”, despite climate emissions from the region being dwarfed by those of G20 nations.

Despite this, the determination of Pacific leaders and communities was undeniable – they came together for meaningful and difficult conversations about priorities, and the messages they want to share with the world.

Overwhelmingly, there was a strong commitment to ensuring science was central to the global response to climate change. This led to calls for more Pacific voices at the scientific negotiations at COP31.

1.5°C is a lifeline

In UN climate diplomacy, Pacific nations are often dubbed “Small Island Developing States”. In contrast, during the talks this week,Pacific representatives deliberately referred to their nations as “Big Ocean States” or BOS, (appropriately pronounced as “boss”).

This reflects the way a healthy and thriving ocean underpins a healthy and thriving way of life in the Pacific.

Although a recent UN report found we will likely pass 1.5°C above pre-industrial temperatures in 2030, an intensified push to phase out fossil fuels and cut emissions could see this limited to 1.8°C. In theory, carbon removal methods could then be used to bring temperatures back to 1.5°C or below this century.

However, Pacific delegates emphasised remaining below 1.5°C is a lifeline for their region, and the response to overshooting this needs to be as brief and effective as possible to preserve their safety and cultural identity.

Who foots the bill?

Who will pay for the cost of climate change was a key area of discussion. Delegates called for accessible, predictable and fit-for-purpose funding, and for greater commitments of climate finance capital at COP31 in November.

There are already examples of how effective funding can be.

The Pacific Resilience Facility (PRF), is a Pacific-managed climate fund established by treaty, with Pacific members in the driver’s seat. It has already made a significant impact, only five months since it received funding from the UN.

For example, a speaker from Palau talked about the taro patch (a tropical root vegetable) as the “mother of life” in the Pacific region. Taro is under threat from salt-water intrusion and extreme weather, which imperils Pacific livelihoods.

With only US$4,000 (A$5,700) of transitional funding, the PRF was able to support a women-led project to restore taro patches (mesei), which play a vital role in food security and irrigation. The power of a women- and Indigenous-led initiative was clear.

Setting a precedent

In Fiji, I witnessed open negotiations driven by stories of real challenges and a genuine desire for the world to engage with those affected by climate change.

In the face of criticism over the efficacy of the UN’s COP process, this kind of humanity is often missing from global climate talks. Reaching beyond participation to relationships may set us up for the significant climate progress the Pacific – and every nation on earth – desperately needs.

The ultimate success of this year’s unique Fiji meetings will not be clear until November, but I hope we see future summits centred not just on participation, but human connection.The Conversation

‘1.5°C to stay alive’: Pacific countries demand the world makes good on climate promises

Leaders and delegates from countries including Australia, Germany, Nepal and Pacific nations began climate meetings in Fiji on Monday to discuss the threat of climate change to small island nations.

These meetings are a curtain-raiser for the annual United Nations climate summit known as COP31, being held in Turkey (also called Türkiye) in early November. Australia is jointly hosting and leading these Pacific climate meetings with Fiji, as part of a compromise deal struck at last year’s COP30 with Turkey.

Australian Prime Minister Anthony Albanese arrived in Fiji on Monday afternoon, and Climate Change Minister Chris Bowen promised $7.29 million towards the region’s renewables transition. Local media reports suggest a Pacific declaration could be made calling for fair representation in climate governance for small island states and guaranteed funding.

This might officially only be a pre-COP meeting, but it feels more like an Oceania COP. As of Sunday evening, there were almost 600 people registered as official country negotiators, and another 2,560 at the event from civil society, academic, activist and community groups. As well as Albanese and Bowen, former Australian Prime Minister Julia Gillard and New Zealand’s former leader Jacinda Ardern will speak.

Australia’s engagement with the Pacific

Australia has a national interest in being the security partner of choice for Pacific countries. When the Solomon Islands signed a security deal with China in 2022 it rang alarm bells in Canberra.

Australia has since signed a web of bilateral deals to shore up Australia’s role – first with Tuvalu (2023), Naoero (formerly Nauru) (2024), Papua New Guinea (2025), Vanuatu (2026), and most recently with Fiji in July. Both the Vanuatu and Fiji agreements include a commitment that both parties will pursue a net zero economy.

On Monday, the Coalition in Australia criticised the $20 million Australia reportedly spent on this week’s Pacific meetings as a “farce” and a waste of taxpayer money. But it’s not expensive if understood as part of Australia’s broader engagement with the Pacific, both on security and climate.

What’s top of the agenda this week?

Well, that depends who you ask. Fijian Prime Minister Sitiveni Rabuka on Sunday said that he had three requests for visiting leaders: “We ask them to come, we ask them to see, and we ask them to listen with an open heart to those of us on the front line.”

1.5°C goal

The Pacific led the global fight to secure the 1.5°C temperature goal under Paris. For these countries it is not just an arbitrary number, it’s a threshold for survival – the catchcry is “1.5 to stay alive”.

At an afternoon press conference, Bowen acknowledged a recent UN report found the planet will likely warm past 1.5°C. However, Fiji’s Minister for Environment and Climate Change, Lynda Tabuya, reinforced on Monday morning the message to leaders this week is still to keep 1.5°C within reach.

COP31 envoy Kristina Stege added to this, saying that as the world gets closer to exceeding 1.5°C of warming this is not a reason to abandon the goal that represents the best chance for safety for people across the Pacific and the world. Rather, she said it should be a call to action, with any overshoot of 1.5°C as small and as short-lived as possible.

Electrification

Bowen announced a $7.29 million package to strengthen Pacific energy sovereignty and support the rollout of renewables across the region. Attendees noted, however, that this funding was part of the already-announced $50 million Australia-Pacific Partnership for Energy Transition, and not new funding.

There is part of a push towards the COP31 global goal on electrification, known as “35 by 35”, which aims to increase the share of electricity in the total global energy mix to 35% by the year 2035. Last month, Bowen visited India and Saudi Arabia, and it’s likely he would have discussed the COP31 agenda with both countries.

The UN summit work is decided by consensus and Saudi Arabia – the fourth-largest petrochemical producer in the world – is usually a blocker to action at the summit. So it’s important for Bowen, as the chief negotiator, to find a position that 190 countries can agree with – no easy feat. And it’s more politically palatable for Bowen to talk about electrification than cutting fossil fuels, given Australia’s role as one of the world’s biggest fossil fuel emitters.

Pay up for climate damage

No matter the topic of discussion at these climate negotiations, the question of finance is never far away. Pacific leaders are strongly pushing for a reframing of how this is discussed; climate finance is not aid or charity, but a legal obligation.

This was recently reaffirmed by International Court of Justice, an opinion Australia endorsed in a resolution at the UN General Assembly. Delegates at proceedings on Monday called for developed states like Australia to move from providing voluntary assistance on climate finance, to being reliable and accountable partners that fulfil their obligations.

In practice, what Pacific countries want to see is more rich, heavily polluting countries pledging financial support through the Pacific Resilience Facility, a regional financing institution designed to provide debt-free grants for climate adaptation and disaster preparedness.

Time for action

Across the calls for limiting emissions, making finance accessible, and keeping 1.5°C within reach, there is a strong desire for this meeting to set the stage for COP31 to be a summit of implementation and action.

As Stege said at an event on Saturday in Suva: “The Pacific has been standing awake and sounding the alarm for people and planet for decades.”

Now the world is in the Pacific, the region’s leaders hope they leave with a commitment to action and keeping 1.5 alive.The Conversation

In a year of record‑breaking heat, Australia and Pacific leaders meet to sharpen climate goals

Heatwaves in the United Kingdom, vast forest fires in Canada and flash flooding in Nepal – the evidence of climate change is everywhere. And no region faces a more existential threat than the Pacific, where residents of low-lying nations are witnessing the seas creep higher.

On Monday, leaders and delegates from countries including Australia, Germany, Mexico and Thailand will meet in the Pacific nations of Fiji and Tuvalu. Their discussions aim to highlight the climate threats faced by small island nations and the need to rein in carbon emissions.

These meetings are a curtain-raiser for the annual United Nations climate summit known as COP31, being held in Turkey (also called Türkiye) in early November. It’s fairly unusual for a pre-COP meeting to take place in a different part of the world to the main UN summit.

Australia will jointly host and lead these Pacific climate meetings with Fiji, as part of a compromise deal struck at last year’s COP30. This deal will also see rival bidder Turkey host the UN summit in the city of Antalya in November.

So, what will be on the agenda during the Fiji meeting and the main COP31 event in Turkey? And why does it matter?

Remind me, what is COP?

The Conference of the Parties, or COP, is the annual UN summit that brings countries together to negotiate climate goals. The figures added to the name reflect how many times the UN meeting has been held since its inception; this year is COP31.

The summit will determine the climate actions nearly 200 nations, which have all signed up to the UN Paris Climate Agreement, are expected to take in the coming years. Decisions coming out of the COP reflect political consensus on the way forward, but are generally not binding on countries or enforceable through international litigation.

This year’s co-hosting arrangement has divided the responsibilities between the two nations: Turkey’s Environment Minister Murat Kurum is COP31 President-Designate, while Australia’s Minister for Climate and Energy Chris Bowen will be President of Negotiations.

In practice, this means Turkey will ensure compliance with UN procedural rules, including setting the agenda and adopting decisions. Australia will steward the negotiations, affording it substantial political and technical leadership, but not necessarily control over the overall outcomes of the summit.

Conflict or consensus?

This unprecedented co-hosting arrangement between Australia and Turkey raises questions about how power should be shared between the two parallel roles.

Leadership through consultation forms the foundation of official UN communications from the COP31 summit. In the event of any difference of opinion, both countries will be expected to hold talks to reach a mutually satisfactory conclusion.

However, there is little detail around what this will actually look like. This risks slowing the pace of negotiations, even creating a stalemate if Australia and Turkey fail to reach an agreed decision. Controversial issues could be put off to the next session or sidelined altogether. That happened last year when Saudi Arabia declared any mention of fossil fuels in the decision outcomes an unacceptable “red line”.

What’s at stake?

A recent UN report found the world will likely overshoot the target of holding global warming to 1.5°C, with every increase bringing more extreme weather and environmental harm. But if we substantially increase global efforts to phase out fossil fuels and reduce emissions, peak warming could be limited to 1.8°C.

Carbon removal methods, such as conserving or planting forests, in theory could then bring temperatures back to 1.5°C or below this century. But to achieve this, nations must agree – and follow through – on urgent commitments to cut emissions.

At the heart of the November climate negotiations will be the question of who should pay for a “just transition” away from fossil fuels – one that ensures a fair distribution of the economic burdens and benefits.

With the UN declaring climate finance must reach US$1.3 trillion (almost A$1.9 trillion) a year by 2035, the spotlight is on heavily polluting rich countries to deliver on finance promises.

What will be top of the agenda?

Negotiations at COP31 are likely to focus on implementing countries’ existing commitments. It is the start of the next cycle of the global stocktake – the Paris Agreement process for assessing progress on climate action – which will wrap up in 2028.

The last stocktake in 2023 concluded there was a big gap between countries’ policies and the Paris Agreement’s temperature goals. Whether countries are beginning to bridge that gap depends on how seriously they aim to fulfil their emissions reduction pledges.

Climate finance, as always, is likely to be a major issue of dispute. That’s especially true given funds for loss and damage finance are running low, while countries such as Nepal suffer catastrophic damage from climate disasters.

Why is the Pacific so important?

Australia’s initial bid to host COP31 was made in partnership with the Pacific, to give voice to small countries in the region. Yet Australia continues to face Pacific criticism for failing to shift its economy away from fossil fuel production.

Many Pacific leaders were disappointed at Australia’s acquiescence to Turkey’s bid. But in the face of criticism, Bowen and Australian Prime Minister Anthony Albanese insist they have attracted more high-profile leaders to the Fiji-Tuvalu pre-COP meeting than ever before.

The power of this global climate summit

As a leading voice in the upcoming negotiations, Australia must demonstrate a real commitment to robust climate policies and good-faith relations with its Pacific neighbours.

In previous years, initiatives launched at COP for greater renewable energy deployment and energy efficiency attracted strong support and have helped drive action on the ground. The Turkey and Australian COP31 presidencies will be hoping their 35% electrification target by 2035 has similar cut-through.

If successful, the two countries’ shared leadership model could pave the way for international actions that spotlight the needs of the developing and low-emitting countries that have the most to lose from the climate crisis.The Conversation

Electric long‑haul trucks could become a reality sooner – if there’s no driver

It’s hard to run heavy trucks without fossil fuels – especially in Australia. They’re big, heavy and cover long distances. Powering big rigs with today’s batteries suffers from added weight and cost. Then there’s recharging time.

For smaller trucks covering shorter distances, the task is much easier. The shift is already on in nations such as China. But many experts predict long-haul battery-electric trucks won’t beat diesel on total running costs until the 2030s, when battery prices have fallen far enough.

My recent study suggests that timeline could be too pessimistic for one reason – the emergence of driverless trucks, which are being tested on public roads in the United States.

Australia already has a large fleet of driverless trucks carrying ore in the Pilbara. None are currently on public highways – but that could change. Late last year, transport ministers agreed to allow conditional deployment on selected public roads beginning in 2027.

So far, public debate has focused on driver jobs and safety. But there’s a key factor which we’re not talking about – money. Autonomous trucks change the economics of freight so much they tip the balance in favour of electric.

Drivers make trucks go faster – but at a cost

Today’s heavy trucks have drivers, which means every hour on the road is an hour of wages. To keep wage costs low, freight companies encourage drivers to drive at the speed limit (100kmh for heavy freight) and get the trip done.

Speed has a large hidden cost – especially for heavy freight. Air resistance rises sharply as a truck goes faster, meaning a fast truck uses more fuel per kilometre than a slow one. But for a driven truck, arriving sooner avoids enough expense in the form of wages that it usually outweigh extra fuel costs.

If there’s no driver, the balance flips.

For an autonomous diesel truck, it doesn’t matter as much if the trip takes a bit longer. Using less energy per kilometre means burning a little less fuel.

The difference is more pronounced for autonomous electric trucks, where slower, more energy efficient trips could make it possible to use trucks with smaller, cheaper battery packs. Smaller battery packs also means a truck can carry more freight.

Our modelling shows the optimal speed for an autonomous electric truck is around 80km/h. Because there’s no driver who needs to rest, the trip can potentially be made without stopping.

Sydney to Melbourne, slow and steady

To test whether autonomous electric trucks change the financial equation, I modelled Australia’s busiest freight corridor, Sydney to Melbourne.

The result: autonomy made electric trucks much more competitive with diesel. The effect was the equivalent of a sharp fall in battery prices of A$34 a kilowatt hour. (As of 2025, battery prices were about A$162/kWh.)

In effect, autonomy would make electric trucks significantly more financially appealing and could accelerate adoption by several years.

Freight companies would gain more if they used driverless trucks more hours of the day. At present, a typical long-distance diesel truck is driven 25% of the time.

If autonomous trucks could run 50% of the time, that would boost the financial appeal again. The effect would be the equivalent of cutting battery prices by A$75/kWh.

There’s a crucial caveat: autonomous electric trucks gain this advantage as long as they do most of their charging cheaply at the depot to avoid paying fast charger rates on the Hume Freeway.

Autonomous electric trucks are best suited to medium routes

Most driven electric trucks currently available work best on shorter routes (under 600km). That’s good news, because complex urban environments are likely to be reserved for driven trucks, for safety and regulatory reasons.

Autonomous electric trucks will likely be restricted to specific corridors outside urbanised areas for safety, regulatory and technical reasons.

Three medium-length interstate corridors are well suited for trucks combining autonomy and electrification – Sydney to Melbourne (877km), Brisbane-Sydney (915km) and Adelaide-Melbourne (~726km). These are the busiest in the country.

From impossible to possible

Heavy trucks were long thought to be too hard to electrify. But plunging battery prices have made urban delivery trucks viable, while larger electric trucks are now being released.

My research suggests it’s now possible to electrify much of our heavy freight – and that going autonomous would accelerate financial viability over busy medium-length routes.

Authorities will have to be satisfied that these trucks are safe and resolve questions over potential job losses. But over time, the favourable economics of self-driving electric trucks may well be enough to make them a reality.The Conversation

Conservation parks don’t have to be vast – as one tiny grasshopper reminds us

A vast stretch of land where animals roam widely and plants grow freely. That’s what most people would picture if they thought of a conservation area.

Such places are vital for protecting large animals and entire ecosystems. They make managing environmental threats, such as fire and weed invasions, much easier.

However, some parts of Australia simply don’t have the space to support a large conservation area. This is particularly true in agricultural regions. In the cropping country of northwestern Victoria, for example, remnant reserves may only cover less than 100 hectares.

These smaller reserves are often undervalued and overlooked. However, our latest research reveals these remnant areas can be critical to the survival of smaller plants and animals.

Meet the matchstick grasshopper

Our recent study took a closer look at grasshoppers in western Victoria. We rediscovered a formerly undescribed species of the Keyacris genus of grasshoppers, which includes the threatened Key’s matchstick.

We named the new species as the Murray Mallee matchstick (Keyacris bungunnia) because it lives around the region where an old megalake, Lake Bungunnia, existed during the Pleistocene era. The Murray Mallee matchstick likely hopped about on its shores.

Matchstick grasshoppers, named for their distinctive stick-like appearance, are unique to Australia. The roughly 250 related species are found in many habitats across the country, including desert and mulga scrubland, eucalyptus woodland and grassy plains. Far from being pests, these native grasshoppers are a natural part of Australian landscapes, feeding on native plants and supporting local food webs.

Our latest study, led by student Kim Kaufmann, mapped the distribution of this grasshopper species across several sites. Our findings suggest each population was genetically distinct from the others.

Given matchstick grasshoppers don’t have wings even when fully grown, they don’t typically travel far from where they are born. But in places with continuous habitat, they can spread slowly over generations.

Research shows one species reached northern Tasmania from Victoria while another travelled 2,200 kilometres across the Nullarbor Plain on the way from Kalgoorlie to Broken Hill.

As landscapes become increasingly fragmented, environmental threats such as fire or overgrazing during drought could wipe out whole populations. This is particularly dangerous for animals like the Murray Mallee matchstick that don’t have wings or any other way of shifting to other places.

High quality habitat

There’s a flip side to our findings.

Finding a matchstick grasshopper in a small, remnant reserve could indicate you have stumbled across high quality habitat, home to other vulnerable species.

For example, one of our Murray Mallee matchstick sites was later discovered to support the largest known population of the threatened Eltham copper butterfly (Paralucia pyrodiscus lucida). Many of these insects are poorly studied, even when they play a crucial role in our local ecosystems.

However, these valuable remnant reserves are typically overlooked in conservation efforts and are often poorly managed, overrun by weeds or even covered with rubbish.

Fortunately, conserving these areas for vulnerable animals doesn’t have to be expensive or complex. Grasshoppers can survive as long as food plants are available, even in small patches of suitable habitat. For instance, translocated populations of the Larapuna grasshopper (Vandiemenella viatica) have surged at several revegetated sites near Melbourne.

Most recently, scientists have successfully introduced the threatened Key’s matchstick grasshopper into the Euroa arboretum in northeast Victoria.

The benefits of these projects go beyond grasshoppers. Matchstick grasshoppers are a crucial food source for other insects, spiders and small birds, especially in late winter and early spring when most insects are yet to hatch.

Many insect species, including the Murray Mallee matchstick, have likely persisted in remnant reserves. Conserving and managing these small, and often overlooked, areas is one way to help rare critters thrive.The Conversation

Invasive species do much more damage in Australia and NZ than elsewhere. But why?

If you had to pick the countries where invasive species pose the biggest problems, you probably wouldn’t think of Australia.

The continent has some of the world’s strictest biosecurity, a small human population and a comparatively short period of colonial occupation. It is also girt by sea. All of this should make introduced species less of an issue.

But Australia is one of the top three nations affected by feral species, after the United States and New Zealand.

More than 4,000 species have been introduced at last count. Of these, 3,000 are sufficiently out of control to be considered invasive. The damage they do to crops, infrastructure and nature now costs around 1.25% of GDP – almost as much as Australia spends on aged care.

So why are determined efforts and natural advantages often unable to stem Australia’s feral tide?

Important answers come from island biogeography, a field of study pioneered by Alfred Russell Wallace. He is the scientist who discovered evolution through natural selection, independently from Charles Darwin but at the same time.

Islands are rather isolated environments, which means unique species are more likely to evolve. But isolation also means their inhabitants are particularly vulnerable to invasive species.

Known as the island continent, Australia demonstrates this on a huge scale. Australia has a high number of species found nowhere else, and is one of only 17 megadiverse nations. But the isolation that protected these species over millions of years has left many vulnerable to new threats brought by humans.


Every Australian knows common myna birds are bad, rabbits are worse and feral cats kill native animals unchecked.

But how do we decide what makes an introduced species “good” or “bad” – and will we ever concede that some species are here to stay?

Our new series on invasive species explores these questions.


Lopsided ecosystems, unfilled niches and unwary species

Australia’s biodiversity is largely an accident of its insular history.

Australia was near the South Pole when it broke away from the supercontinent of Gondwana, and the cold climate limited the diversity of animals present. The animals and plants that did make it here afterward found a sparsely inhabited continent.

These colonising lineages often diversified into a wide variety of species. The continent is thus short on lineages, but rich in species.

Most famously, Australia is a marsupial paradise, with a dizzying array of pouched mammals. The continent had almost no ground-dwelling placental mammals until rodents arrived from Asia about eight million years ago.

Australia also has the highest diversity of unique plants of any country on earth.

Across most of the world, largely harmless colubroid snakes account for most snake species. But to the consternation of ophidiophobes (those scared of snakes), most Australian snakes are venomous elapids who descended from relatives of deadly front-fanged cobras.

This lopsided biodiversity makes Australia unusually vulnerable to invasion for three reasons.

First, invasive species can fill ecological niches not well used by native species.

Second, they can be unfamiliar predators or competitors against which Australian species have little defence.

Third, super-invader species are more likely to evolve on larger continents and invade Australia rather than the reverse.

Cats and rabbits, super invaders

A super invader is a fast-breeding species able to eat a broad range of foods, tolerate many different environments and spread quickly. These traits help them quickly colonise new places and outcompete native species.

Species evolving on large, well-connected landmasses are more likely to be good at invading new areas, as their evolutionary adaptations have been honed by encounters with a broader range of adversaries.

Many of Australia’s worst invasive species are super invaders, from cane toads to fire ants. But feral cats and rabbits stand out from the pack. These are Australia’s two costliest invaders.

Cats and rabbits both evolved on Eurasia, the largest landmass. Domestic cats emerged in the Middle East, from a local wildcat. European rabbits are native to Europe’s southwest, where they are actually endangered.

Eurasia’s range of species is much broader than Australia’s. Many wildcats and related species would have co-evolved with marsupials, who lived in Eurasia until around 14 million years ago.

But bilbies evolved in isolation and would never have met any placental predators, let alone cats.

Feral cats are a global issue. But Australia is the epicentre for extinctions driven by cats.

Rabbits have become a problem in many countries, but their voracious appetites and ability to outcompete native species such as bilbies means they have done the most damage in Australia.

Both cats and rabbits have exploited ecological niches not well used by native Australian animals.

No marsupial predators have diets as broad as feral cats, nor do they roam everywhere from the baking deserts of Central Australia to the freezing forests of Tasmania.

Australia has no mid-sized marsupials able to breed like, well, rabbits and devour all greenery in sight. Bettongs prefer roots and fungi, while bilbies are omnivores. Both reproduce much more slowly.

Every other continent has native cat (felids) and rabbit relatives (lagomorphs). But Australia did not, and so our species were uniquely unprepared.

Before human colonisation, the main mammals preying on bilbies were quolls, which are smaller and slower than feral cats.

Many native plants – especially in drier regions – also produce seedlings vulnerable to the ravenous grazing of rabbits.

Worse, rabbits often avoid invasive weeds such as lantana (native to the Americas), as these co-evolved with rabbits or their relatives and acquired defences such as an unpleasant taste.

The blessing and curse of islands

What about New Zealand, which is even more isolated than Australia and has an even more lopsided biota? It’s here that introduced animals from Australia have done the most damage.

While Australia only has a few native land-dwelling placental mammals, New Zealand had none at all.

When wallabies and possums were introduced from Australia, it was easy for them to run rampant and become pests.

But the same species aren’t such a problem elsewhere, as they face much stiffer competition when trying to get a foothold on landmasses packed with placental mammals.

Life on an island can be splendid isolation – until new challengers arrive. This is why Australia (and New Zealand) need such tough biosecurity controls – and why they still suffer the most damage from invasive species.The Conversation

Hoping for a ‘new normal’ climate is pointless. We must learn to adapt

Climate change is worsening. There’s now no chance of holding temperature rise to 1.5°C. The future will bring worsening floods, glacial melt, megafires and lethal heat.

But can we call this the “new normal”? The phrase has become common in discussions about the upheavals and damage stemming from human-caused climate change.

It’s human nature to want the future to be predictable: we are creatures of routine. If the Earth’s climate really was going to settle into a “new normal” at 1.5°C of warming, we would find the idea comforting.

Unfortunately, it’s not true. Passing the 1.5°C threshold isn’t like stepping from one state into another. Global emissions of greenhouse gases are slowing, but have not yet peaked – let alone begun to fall. That means further heat, greater change and more climate uncertainty.

Many different futures are possible after 1.5°C. As Australia’s National Climate Risk Assessment spelled out last year, our future looks very different at 2°C. At 2.5°C, it’s something else again. At 3°C, it’s unrecognisable. Thinking of any of these futures as a new normal invites a dangerous misunderstanding of future risk.

What is a ‘normal climate’ anyway?

By “normal”, we mean usual and expected – a situation following predictable patterns.

“Climate” isn’t day to day weather: it’s the statistical fingerprint of weather patterns over 30 years, spanning typical weather through to rarer extremes.

For many weather phenomena, we lack reliable long-term data. As a result, we are often surprised by “unprecedented” events – even though some may actually sit within a pre-industrial natural range, representing rare extremes our records haven’t captured.

As a result, we’re exiting the old normal without having the data to fully understand what we’re leaving behind.

What happens to ‘normal’?

We might expect a steadily warming world will cause steady change to existing weather phenomena – hotter days, more rain, longer droughts.

Unfortunately, our desire for predictability won’t be satisfied here either. Weather will change unpredictably, meaning we can expect new extremes as well as new combinations, such as drought to flood climate whiplash and pyrocumulus clouds (thunderstorms forming from bushfires), which were virtually unknown a few decades ago.

Once-rare weather extremes will arrive more often, with more intensity and often lasting longer, like this year’s record-breaking European heatwaves.

We can no longer take a 30-year average of past extreme weather and extrapolate that into the future. We don’t know what will emerge as the atmosphere undergoes very rapid change at rates humans have never experienced.

Can we adapt to the unknown?

To date, much of the focus of global climate negotiations has been on mitigation – trying to stop climate change from getting worse by reducing emissions and protecting nature. Efforts to reduce emissions have helped, but at nowhere near the scale needed.

This failure to cut emissions has driven the view that climate change is inescapable. But this isn’t helpful. We will have to learn to adapt to the future climate.

If this seems scary, it might help to remember that we haven’t actually been in a stable climate state in our recent past.

Climate-related risks have been growing (even without climate change) over the past century, because of the growth of cities, infrastructure, farms and more.

Even without the influence of climate change, an intense heatwave, drought or bushfire in Australia will play out over natural habitat which is more fragmented and degraded than it used to be, making it harder for animals to escape.

A strong coastal storm surge falling in a historically known range can reach more people, houses and businesses than it would have just 50 years ago – because there are more people on the coasts.

For these threats, climate change acts as a risk-multiplier. As temperatures climb and rainfall becomes more variable, our ability to respond becomes more limited.

It’s increasingly less useful to look to the past as a guide to the extreme weather of the future. temizyurek/Getty

What can we do?

Many people fear the uncertainty of climate change. Some are already grieving the current losses and those to come, or feel rage at our unwillingness to change course. These responses are understandable. We must act in empowering and hopeful ways – without shying away from the gravity of the task.

If we take a longer view, we can see Homo sapiens are highly adaptable. Faced with these threats, we will look for ways to adapt and cope, as we have done for millennia.

If we give up on the comforting idea of normal – old and new – we can focus on practical measures. These include bringing climate adaptation to the fore while embracing a future of clean energy, electric transport and regenerative farming to help reduce emissions.

It’s a mistake to focus either on reducing emissions or adapting to a warming world – we need both. Adaptation will be easier if we limit future warming.

The first step is to give up the idea of a “new normal”. We can no longer look to the past to predict the future climate, and we know that climate change will continue to intensify until such time as we stop it. We do not know what is to come.The Conversation

Africa’s rhinos often get the spotlight – but Indonesia’s two rhino species are far closer to extinction

Michelle Campbell-Ward, University of Sydney

Small, hairy and cheekily charismatic.

Those words sprung to mind when I first met a Sumatran rhinoceros (Dicerorhinus sumatrensis) after traversing the maze of wooden slatted paths at the conservation centre in the dense, humid forests of Malaysian Borneo.

It was 1998 and I was an eager student volunteer at the centre. At that time, 300 Sumatran rhinos were thought to exist globally.

I saw this female rhino as a symbol of conservation hope. But today, according to the International Rhino Foundation’s 2026 State of the Rhino report, less than 50 Sumatran rhinos remain. All are found in Indonesia. The Javan rhino (Rhinoceros sondaicus) is just as rare.

While these figures rely on estimates, the trajectory is alarming.

So what is driving this decline? And how can we protect the few Sumatran and Javan rhinos that are left?

Majestic mammals

In modern culture, rhinos represent strength, power and security. We use them as sports mascots and feature them in everything from car logos to safety equipment brands.

Their ubiquity in popular culture may lead us to underestimate the urgency of their plight. Species used as marketing emblems are often considered more common than they truly are.

There are five surviving species of rhinos. I have had the privilege of getting to know all but one while working as a wildlife veterinarian in zoos, sanctuaries and the wild.

Africa is home to white and black rhinos, whose populations have fluctuated greatly throughout history. The water-loving greater one-horned rhino lives in India and Nepal and has seen a steady recovery from near extinction in the early 1900s. These three species can be found in zoos and tend to get the most public attention.

Compared to their African and Indian relatives, Sumatran and Javan rhinos typically fly under the radar. However, their critically endangered status signals these animals are in urgent need of assistance.

The rarest rhinos

According to the latest State of the Rhino report, the future of the elusive Javan rhino and the small, hairy Sumatran rhino is now especially precarious. Distribution is a major reason why.

There are roughly 50 surviving Javan rhinos. All live in a single protected area, Ujung Kulon National Park on the island of Java. Due to nearby converging tectonic plates, it is vulnerable to earthquakes and tsunamis. One natural disaster could well exterminate the Javan rhino population.

In contrast, the several dozen remaining Sumatran rhinos are scattered into many subpopulations, across two islands. This means the chance of a wild individual rhino encountering another of their kind is remote or even impossible. With no prospect of finding a compatible mate, isolated survivors are destined to be the end of their genetic line.

Searching for sanctuary

To protect this fragmented population, the International Rhino Foundation established the Sumatran Rhino Sanctuary in 1996. It is located in Way Kambas National Park on the island of Sumatra.

The sanctuary is currently home to ten intensively managed, semi-captive Sumatran rhinos. The resident animals live in large, natural rainforest habitats. They are provided with nutrition, security and regular veterinary care.

Increasing rhino numbers through natural or assisted breeding requires patience. Females give birth to a single calf after about 16 months of pregnancy. It may be several years before they have another. Infertility is a recognised problem in some rhinos.

The sanctuary has had some hard-won successes. Five Sumatran rhino calves were born there between 2012 and 2023, in part due to close reproductive management and monitoring. Excitingly, authorities have just announced two new pregnancies.

Camera-trap footage has also confirmed the births of up to five Javan rhino calves in Ujung Kulon in recent years. These precious births go some way towards recovery of these two species.

The perils of poaching

Poaching is a persistent threat to all rhino species. Worryingly, global demand for rhino horn is increasing, especially in China and Vietnam. Besides its long-standing use in traditional medicine, rhino horn now plays a role in demonstrating wealth and status, particularly in business circles. Poachers killed as many as 26 Javan rhinos between 2019 and 2023 alone.

Anti-poaching strategies include behaviour change campaigns, which focus on promoting social and cultural unacceptability of horn use and purchase. Governments may also rely on intelligence-led law enforcement and disruption to large crime syndicates to stop poachers. While poaching convictions and court sentences are increasing, including in Indonesia, this is not enough to keep the world’s rhinos safe.

Proactive measures, such as protecting and restoring habitat suitable for each species, are vital to the recovery of rhino populations. This is particularly true as humans increasingly encroach on wild places.

Where to from here

Translocation – capturing and then releasing animals in a new place – is one possible way of protecting the world’s rhinos. Recent research examined whether this strategy could be used to re-establish populations of Sumatran and Javan rhinos across their former range throughout Southeast Asia. Conservation authorities can learn from past translocations of African rhinos, which show finding suitable habitat, anti-poaching protection and careful planning are crucial to the success of these efforts.

More broadly, effective rhino conservation relies on having an army of supporters. Local communities should tangibly benefit from living alongside rhinos, for example through job creation and by sharing in the proceeds of ecotourism. Even from afar, people can help by supporting conservation organisations and avoiding the purchase of products that contribute to tropical deforestation.

Sustainable funding and political commitment are crucial to protecting the few Indonesian rhinos that remain. It’s my wish that younger generations, including my future students, have the privilege of meeting a small, hairy rhinoceros for themselves.The Conversation

Shorebird Identification Booklet

The Migratory Shorebird Program has just released the third edition of its hugely popular Shorebird Identification Booklet. The team has thoroughly revised and updated this pocket-sized companion for all shorebird counters and interested birders, with lots of useful information on our most common shorebirds, key identification features, sighting distribution maps and short articles on some of BirdLife’s shorebird activities. 

The booklet can be downloaded here in PDF file format: http://www.birdlife.org.au/documents/Shorebird_ID_Booklet_V3.pdf

Paper copies can be ordered as well, see http://www.birdlife.org.au/projects/shorebirds-2020/counter-resources for details.

Download BirdLife Australia's children’s education kit to help them learn more about our wading birdlife

Shorebirds are a group of wading birds that can be found feeding on swamps, tidal mudflats, estuaries, beaches and open country. For many people, shorebirds are just those brown birds feeding a long way out on the mud but they are actually a remarkably diverse collection of birds including stilts, sandpipers, snipe, curlews, godwits, plovers and oystercatchers. Each species is superbly adapted to suit its preferred habitat.  The Red-necked Stint is as small as a sparrow, with relatively short legs and bill that it pecks food from the surface of the mud with, whereas the Eastern Curlew is over two feet long with a exceptionally long legs and a massively curved beak that it thrusts deep down into the mud to pull out crabs, worms and other creatures hidden below the surface.

Some shorebirds are fairly drab in plumage, especially when they are visiting Australia in their non-breeding season, but when they migrate to their Arctic nesting grounds, they develop a vibrant flush of bright colours to attract a mate. We have 37 types of shorebirds that annually migrate to Australia on some of the most lengthy and arduous journeys in the animal kingdom, but there are also 18 shorebirds that call Australia home all year round.

What all our shorebirds have in common—be they large or small, seasoned traveller or homebody, brightly coloured or in muted tones—is that each species needs adequate safe areas where they can successfully feed and breed.

The National Shorebird Monitoring Program is managed and supported by BirdLife Australia. 

This project is supported by Glenelg Hopkins Catchment Management Authority and Hunter Local Land Services through funding from the Australian Government’s National Landcare Program. Funding from Helen Macpherson Smith Trust and Port Phillip Bay Fund is acknowledged. 

The National Shorebird Monitoring Program is made possible with the help of over 1,600 volunteers working in coastal and inland habitats all over Australia. 

The National Shorebird Monitoring program (started as the Shorebirds 2020 project initiated to re-invigorate monitoring around Australia) is raising awareness of how incredible shorebirds are, and actively engaging the community to participate in gathering information needed to conserve shorebirds. 

In the short term, the destruction of tidal ecosystems will need to be stopped, and our program is designed to strengthen the case for protecting these important habitats. 

In the long term, there will be a need to mitigate against the likely effects of climate change on a species that travels across the entire range of latitudes where impacts are likely. 

The identification and protection of critical areas for shorebirds will need to continue in order to guard against the potential threats associated with habitats in close proximity to nearly half the human population. 

Here in Australia, the place where these birds grow up and spend most of their lives, continued monitoring is necessary to inform the best management practice to maintain shorebird populations. 

BirdLife Australia believe that we can help secure a brighter future for these remarkable birds by educating stakeholders, gathering information on how and why shorebird populations are changing, and working to grow the community of people who care about shorebirds.

Report illegal dumping

NSW Government

The RIDonline website lets you report the types of waste being dumped and its GPS location. Photos of the waste can also be added to the report.

The Environment Protection Authority (EPA), councils and Regional Illegal Dumping (RID) squads will use this information to investigate and, if appropriate, issue a fine or clean-up notice. Penalties for illegal dumping can be up to $15,000 and potential jail time for anybody caught illegally dumping within five years of a prior illegal dumping conviction.

The Green Team

Profile
This Youth-run, volunteer-based environment initiative has been attracting high praise from the founders of Living Ocean as much as other local environment groups recently. 
Creating Beach Cleans events, starting their own, sustainability days - ‘action speaks louder than words’ ethos is at the core of this group.

Wildlife Carers and Organisations in Pittwater:

Sydney Wildlife rescues, rehabilitates and releases sick, injured and orphaned native wildlife. From penguins, to possums and parrots, native wildlife of all descriptions passes through the caring hands of Sydney Wildlife rescuers and carers on a daily basis. We provide a genuine 24 hour, 7 day per week emergency advice, rescue and care service.

As well as caring for sick, injured and orphaned native wildlife, Sydney Wildlife is also involved in educating the community about native wildlife and its habitat. We provide educational talks to a wide range of groups and audiences including kindergartens, scouts, guides, a wide range of special interest groups and retirement villages. Talks are tailored to meet the needs and requirements of each group. 

Profile

Found an injured native animal? We're here to help.

Keep the animal contained, warm, quiet and undisturbed. Do not offer any food or water. Call Sydney Wildlife immediately on 9413 4300, or take the animal to your nearest vet. Generally there is no charge. Find out more at: www.sydneywildlife.org.au

Southern Cross Wildlife Care was launched over 6 years ago. It is the brainchild of Dr Howard Ralph, the founder and chief veterinarian. SCWC was established solely for the purpose of treating injured, sick and orphaned wildlife. No wild creature in need that passes through our doors is ever rejected. 

Profile

People can assist SCWC by volunteering their skills ie: veterinary; medical; experienced wildlife carers; fundraising; "IT" skills; media; admin; website etc. We are always having to address the issue of finances as we are a non commercial veterinary service for wildlife in need, who obviously don't have cheque books in their pouches. It is a constant concern and struggle of ours when we are pre-occupied with the care and treatment of the escalating amount of wildlife that we have to deal with. Just becoming a member of SCWC for $45 a year would be a great help. Regular monthly donations however small, would be a wonderful gift and we could plan ahead knowing that we had x amount of funds that we could count on. Our small team of volunteers are all unpaid even our amazing vet Howard, so all funds raised go directly towards our precious wildlife. SCWC is TAX DEDUCTIBLE.

Pittwater's Environmental Foundation

Pittwater Environmental Foundation was established in 2006 to conserve and enhance the natural environment of the Pittwater local government area through the application of tax deductible donations, gifts and bequests. The Directors were appointed by Pittwater Council. 

 Profile

About 33% (about 1600 ha excluding National Parks) of the original pre-European bushland in Pittwater remains in a reasonably natural or undisturbed condition. Of this, only about 400ha remains in public ownership. All remaining natural bushland is subject to encroachment, illegal clearing, weed invasion, feral animals, altered drainage, bushfire hazard reduction requirements and other edge effects. Within Pittwater 38 species of plants or animals are listed as endangered or threatened under the Threatened Species Act. There are two endangered populations (Koala and Squirrel Glider) and eight endangered ecological communities or types of bushland. To visit their site please click on logo above.
