Habitat Being Destroyed For Profit: Wildlife Leaping From Trees Being Cleared Under Them - Video
This is happening in Noosa at present - this is glossy cockatoo habitat and food trees and this is occurring during their breeding season.
At 1:39 you can see a mother ringtail leap from the tree that's being ripped out from under her to the machine. The wildlife 'spotters' were MIA or behind the machine - one later found the ringtail and one of the babies that was left, still clinging to mum's back.
It is ILLEGAL to do this in QLD; to hurt or endanger wildlife.
Furthermore, the Glossy Black-Cockatoo, Calyptorhynchus lathami, are one of the more threatened species of cockatoo in Australia and are listed as vulnerable under QLD and NSW legislation.
Those sharing and bearing witness to this have asked Pittwater online to share a petition at: https://www.change.org/p/uniting-church-help-spencer-to-stop-the-church-to-save-our-glossies
Join The Fight Against Foxes On The Northern Beaches
Northern Beaches residents are invited to hear how they can join the fight against foxes in their area at a free online event on April 5th.
A joint initiative between NSW DPI, Greater Sydney Local Land Services and Northern Beaches Council, the webinar will feature a range of expert speakers and local information.
Greater Sydney LLS Senior Biosecurity officer Gareth Cleal said the event would give residents advice and information based on real life scenarios and experiences.
“There is no doubt foxes are becoming more and more prominent in urban areas of Sydney and the Northern Beaches is not immune,” he said.
“We regularly receive reports of fox sightings in the area and there are simple steps residents can take to help reduce their impact.”
Mr Cleal said foxes were attracted by food scraps and domestic pets like chickens and rabbits.
“Residents can help by ensuring compost bins are kept secure and properly closed, keeping household rubbish in a secure location, feeding domestic pets inside, ensuring food is not left outside and wherever possible, keeping pets inside overnight,” he said.
“Keeping yards in check by tidying gardens, weeding to reduce fox harbour and housing backyard chickens in secure, fox-proof enclosures rather than free ranging will also help.”
The webinar will feature presentations from local pest animal experts, and cover topics including:
- How to minimise impacts to your pets and native wildlife
- Recording/reporting foxes into FoxScan - https://www.foxscan.org.au/
- An update on local programs
Synthetic Fields: Independent Review Report Due Mid Year
The Independent review into the design, use and impacts of synthetic turf in public open spaces by the NSW Chief Scientist and Engineer has tabled its initial report in February 2022, with the final report due mid-year.
Pittwater Online News has been conducting research into the environmental impacts and feasibility of the planned introduction of more of these fields into our area, along with speaking to resident Julia Walsh over several months. Julia first brought the fragmentation of one of these fields to our attention in August 2021.
Julia has sent in a video update on one of the grassed areas for which synthetic fields is proposed, alongside Manly Creek, taken after the recent rains.
The February 2022 interim report may be accessed at: www.chiefscientist.nsw.gov.au/independent-reports/synthetic-turf-in-public-spaces
Melwood Oval at Forestville has had a synthetic field installed and during heavy rains Julia witnessed "pulverised rubber" washing off and down pathways.
"It's not just the plastics that you can see, it's the plastics you can't see," Julia stated in 2021.
"The biggest concern is that we're putting these fields in water catchment zones."

Millers Reserve at Manly Vale is among seven greenspaces across the LGA that will be "upgraded" to a synthetic surface, with a $203,000 tender already awarded for the works. Millers Reserve is located beside Manly Creek, which flows to Manly Dam, and Ms Walsh is concerned about run-off there.
At their March 2021 council meeting, councillors Stuart Sprott and Roslyn Harrison called for council to halt approvals of synthetic fields pending a NSW Government investigation into sustainable alternatives, which was called for by Planning Minister Rob Stokes. Their response was not supported by other councillors.
Seven new synthetic ovals are planned for our area, including one being touted for Careel Bay, which floods during rain events with refuse carried into the wetlands alongside these. Careel Bay is a Wildlife Preservation Area (WPA) due to its importance to resident wildlife as well as migratory birds, many of which are endangered species.

Hawk Moth Caterpillars
These are Hawk Moth caterpillars on food plant Cayratia. Young ones camouflage by being green, older ones change to browns. Theretra indistincta has bright green spots on its spiracles where it takes in oxygen along its sides. Theretra latreillii’s spiracles just look like dots. Cayratia aka Native Grape grows madly in this weather but watch out for these lovely grubs before you clear it too energetically.
There are an estimated 850 species of Hawk Moth world wide, with the highest diversity occurring in wet tropical regions. Australia has 65 species and in the Sydney region 21 species are known.
The larvae (caterpillars) are large and often colourful, usually with a long horn near the end of the body. Many have lateral stripes and/or large eye spots on the thorax and abdominal segments. The colour patterns help to camouflage the caterpillars and the large eye spots may assist in warding off predators. The caterpillars don't bite or sting but may regurgitate green fluid (from a previous meal) if annoyed.
Adult Hawk Moths are medium to large in size. They are streamlined, robust flyers with an obvious head and large eyes. The forewings are long and narrow and much larger than the hind wings. When the moth is at rest the wings are tented over the body. The abdomen is large and has a tapered cigar-shape appearance. Hawk moths often have a long proboscis, coiled when not in use, which is used in nectar feeding. The adult moth hovers in front of flowers and inserts its proboscis to drink the nectar.

Theretra latreillii, the pale brown hawk moth, is a moth of the family Sphingidae described by William Sharp Macleay in 1826. Mr. Macleay emigrated to Australia in 1839, living briefly at the Colonial Secretary's House in Macquarie Place with his parents before moving in September of that year to the family's still unfinished Elizabeth Bay House. Mr. Macleay was interested in the natural history of Australia, the marine fauna around Port Jackson in particular. Later, he collected a large number of Australian insects; on his death, these were bequeathed to his cousin William John Macleay, whose interest in natural history he encouraged and who in 1888 transferred them to the Macleay Museum, University of Sydney, for which act he was knighted. He also encouraged the scientific interests of his brother George Macleay.
Common moths found in suburban gardens include the Impatiens Hawk Moth (Theretra oldenlandiae), Pale Brown Hawk Moth (T. latreilla), Bee Hawk Moth (Cephonodes kingii) and the Privet Hawk Moth (Psilogramma menephron). Adults are usually most active at dusk or at night but some, such as Bee Hawks, fly during the day.
The Sphingidae are a family of moths (Lepidoptera) called sphinx moths, also colloquially known as hawk moths, with many of their caterpillars known as “hornworms”; it includes about 1,450 species. It is best represented in the tropics, but species are found in every region. They are moderate to large in size and are distinguished among moths for their agile and sustained flying ability, similar enough to that of hummingbirds as to be reliably mistaken for them. Their narrow wings and streamlined abdomens are adaptations for rapid flight.
The family was named by French zoologist Pierre André Latreille in 1802. Sphingidae are named for their hovering, swift flight patterns - from New Latin, from Sphing-, Sphinx, type genus + -idae, New Latin, from Latin, from Greek -idai, suffix indicating offspring. Theretra is a genus of moths in the family Sphingidae. The genus was established by Jacob Hübner in 1819.
Cayratia is from Latin Cayratia, from the Annamese vernacular name, cay-rat, a vine + ia, forming nouns adopted unchanged from Latin or Greek (such as militia ), and modern Latin terms (such as utopia) forming names of genera and higher groups ("dahlia") and forming names of countries (Australia).The genus Cayratia consists of species of vine plants, typical of the tribe Cayratieae.
Some hawk moths, such as the hummingbird hawk-moth or the white-lined sphinx, hover in mid-air while they feed on nectar from flowers, so are sometimes mistaken for hummingbirds. This hovering capability is only known to have evolved four times in nectar feeders: in hummingbirds, certain bats, hoverflies, and these sphingids (an example of convergent evolution). Sphingids have been much studied for their flying ability, especially their ability to move rapidly from side to side while hovering, called "swing-hovering" or "side-slipping". This is thought to have evolved to deal with ambush predators that lie in wait in flowers.
Sphingids are some of the faster flying insects; some are capable of flying at over 5.3 m/s (19 km/h). They have wingspans from 4 cm (1+1⁄2 in) to over 10 cm (4 in).

Australian Government Delists The Majestic Humpback Whale
On February 17th 2022 Federal Environment Minister Sussan Ley announced that Australia has delisted the Megaptera novaeangliae (Humpback Whale) from the Environment Protection and Biodiversity Conservation (EPBC) Act’s Endangered Species listing.
Ms Ley cited numbers of around 40 thousand humpbacks mean it is no longer endangered.
This decision, Minister Ley outlines, is based on scientific research however ORRCA states it is shocked by this statement as are many other groups who have worked for the last 3 and a half decades to protect and save this species.
''When ORRCA was founded back in 1985, there were few Humpbacks observed passing our coasts. Thankfully, with the IWC enforcing a moratorium on commercial whaling in 1986, we have watched this species slowly recover year on year. This is one of humans’ conservation success stories, one that Australia can also be proud of for its role.'' a statement from the group says.
''ORRCA documented its strong conservation view in its submission to the Minister back in March of 2021. In general, there hasn’t been enough research done to support removing this whale from the Endangered Species list. As an organisation who has protected and rescued marine mammals for over well over three decades, we have been a part of and have seen the Humpback success story unfold. However, how stable are their numbers?''
''We believe that a reasonable concern for the whales’ future can be underpinned by science and that the process of their assessment should take this fully into account. Whilst we appreciate that the Humpback will be given protection in Australian waters under the EPBC Act, this isn’t enough for such an iconic species. Even under this Act there will be issues with responding to breaches, enforcing the Act and fining or reprimanding those who wilfully and continually break the law.'' an ORRCA spokesperson has stated
''Whaling nations such as Japan have previously expressed an interest in taking Humpbacks in the Southern Ocean, for scientific research, and has certainly taken many other species over the years. They could see this as a new opportunity and venture down into the Southern Ocean once again, exploiting these still vulnerable whales.
''While the threat of whaling is not an immediate issue, there are still many other issues that need to be considered. For example, the warming of the ocean impacts the routes these whales travel when migrating up and down our countries coastlines making monitoring and research difficult. The Humpback is faced with increasing human interaction, ship strike, pollution, a plastic and micro plastic epidemic, entanglement in fishing gear and shark nets, and then there is the increase in ocean noise or acoustic pollution which effects many whale species. Unless the Government gets serious about addressing the threats to marine mammals and marine life in general, our oceans will be faced with unrepairable and long-term impacts.
''Maintaining Humpback populations in sustainable balance is critical to maintaining biodiversity in the region, and as part of the marine ecology provides high economic and cultural value to the Australian economy through tourism activity.
''From an ORRCA perspective, the protection status, needs to be fully evaluated from not only a scientific perspective, but also an economic, cultural and community perspective to ensure that objective fact and decision making occurs for a species still recovering from critical threat, and in a rapidly changing environment.
''Australia has the highest rate of species facing extinction and following the black summer bush fires, we must do everything we can to stop any more species being lost. Without these important protections, the Humpback will potentially end up right back on the Endangered species list in the future!
''As long-lived, slow-breeding animals that live in cooperative family groups, Humpback populations are exceptionally vulnerable to depletion and will always be slow to recover whatever causes this depletion and this is one key reason why they continue to need the highest level of protection.
''ORRCA believes that the delisting of the Humpback at this time is premature. Our view would be to invest in more solid research of the species, climate change, and our oceans viability to sustain the Humpback before there was any revision of its status.''
The Sydney Edible Garden Trail 2022: March 26-27 - Local Sites
Peek inside some of Sydney’s private backyard fruit and veggie gardens this March, and discover their secrets to living sustainably.
Whether you’re a new or experienced gardener, the best way to learn how to grow juicy fruit and vegetables in your own backyard is to talk to a gardener who’s already doing it. Sydneysiders will have the opportunity to do this over the weekend of 26 & 27 March 2022 when over 50 suburban, community and school gardens will open for the Sydney Edible Garden Trail (SEGT).
Matthew Elphick, one of the garden hosts who participated last year, was inspired to reopen his garden again this year. He’s looking forward to the 2022 trail, saying “It was so wonderful to open last year and have people come through the garden and see how excited they are. You get to see the garden through their eyes, things that you don’t think much about, they find amazing. It’s such a great opportunity to meet like-minded people.”
With the motto “We don’t just grow food, we grow sustainable communities”, SEGT arranges for gardens to open to the public and allocates profits from ticket sales towards building stronger community and school gardens through a grants program with 8 gardens provided with grants in 2021.
This year the trail is extending to the wider Sydney metropolitan area with many new gardens included. Tickets are now on sale at https://sydneyediblegardentrail.com/tickets/
Those in our area listed so far for the 2022 edition of SEGT include:
Newport Community Garden
We are a membership based Community Garden of local neighbours who get together to learn about organic gardening, sustainable living, socialise and have a good time!
NCG has been running for over 8 years and from humble beginnings is now a vibrant, sustainable and inviting space with over 35 garden beds, compost bays, worms farms and native bee hive, green house, water tanks and garden shed.
We grow organic fruits, vegetable and herbs. We cultivate our compost, make our own natural pesticides and grow from seeds saved from our seasonal harvest.
It’s not just hard work, we are very social too and always finish the day with a cuppa and chat with local community members.
In November 2021 Newport Community Garden were announced as one of fifty SEGT GRANT RECIPIENTS 2021.
The grant will be used to attract local birdlife and bees by planting some native bush food plants and others native plants.
“The glory of gardening: hands in the dirt, head in the sun, heart with nature. To nurture a garden is to feed not just on the body, but the soul.” - Alfred Austin

Local Wildlife Rescuers And Carers State That Ongoing Heavy Rains Are Tough For Us But Can Be Tougher For Our Wildlife:
- Birds and possums can be washed out of trees, or the tree comes down, nests can disintegrate or hollows fill with water
- Ground dwelling animals can be flooded out of their burrows or hiding places and they need to seek higher ground
- They are at risk crossing roads as people can't see them and sudden braking causes accidents
- The food may disappear - insects, seeds and pollens are washed away, nectar is diluted and animals can be starving
- They are vulnerable in open areas to predators, including our pets
- They can't dry out and may get hypothermia or pneumonia
- Animals may seek shelter in your home or garage.
You can help by:
- Keeping your pets indoors
- Assessing for wounds or parasites
- Putting out towels or shelters like boxes to provide a place to hide
- Drive to conditions and call a rescue group if you see an animal hit (or do a pouch check or get to a vet if you can stop)
- If you are concerned take a photo and talk to a rescue group or wildlife carer
There are 2 rescue groups in the Northern Beaches:
Sydney Wildlife: 9413 4300
WIRES: 1300 094 737
Please be patient as there could be a few enquiries regarding the wildlife.
Generally Sydney Wildlife do not recommend offering food but it may help in some cases. Please ensure you know what they generally eat and any offerings will not make them sick. You can read more on feeding wildlife here

Tracking Paddles Of Platypuses In The Blue Mountains
March 23, 2022
Platypus DNA has been detected at 29 sites in the Blue Mountains due to a ground-breaking detection technique funded by the Australian and NSW Governments. Federal Minister for the Environment Sussan Ley has stated this week the use of environmental DNA tracking was vital in supporting the recovery of the elusive platypus after the Black Summer bushfires.
“If we want to best support the recovery of species like the platypus, we need coordinated action on the ground that includes monitoring and research across the entire the range of the animal,” Minister Ley said.
“Using cutting-edge eDNA technology will help us understand more about the platypus – simply locating this iconic native species will help remove one of biggest obstacles we have faced in supporting its recovery after the fires.
“It may be improving water quality by fixing soil erosion or removing sediment and debris from rivers to help them feed, but if we know where the platypus live, we can deliver the right support to the right location.”
The NSW Minister for Environment James Griffin said that until recently, tracking teams would need to spend hours beside waterways waiting for the elusive mammals to appear.
“What we’re doing now is using high-tech DNA science to build a snapshot of how platypuses are faring, particularly after the recent devastating bushfires in the Blue Mountains,” Mr Griffin said.
“So far, we’ve discovered platypus DNA at 29 of the 67 National Parks sites sampled, including in some waterways we didn’t previously know they lived in.”
As they swim, platypuses shed small traces of skin cells or body secretion into waterways, which can be detected via environmental DNA testing of water samples.
More sampling will take place in Autumn, when breeding females emerge from their burrows with their puggles and take to the water.
“These mammals can face threats of habitat loss, predation by feral animals and they can drown if they become tangled in fishing lines or yabby traps,” Mr Griffin said.
“I want to make sure we’re doing all we can to protect the species, which is why this research is so important. It’s helping us ensure precious platypus habitat is being conserved and protected now and into the future.”
So far, platypuses have been detected in the Blue Mountains, Wollemi, Kanangra-Boyd, Nattai, Mount Royal, Turon, Marrangaroo and Bangadilly National Parks and Upper Nepean State Conservation Area.
The project is being delivered by the NSW Government, supported by $23,000 from the Australian Government’s Bushfire Recovery for Wildlife and their Habitats fund.

Summer Soaking Brings Superb Results For Endangered Orchid
March 23, 2022
The endangered superb midge orchid has continued its streak of record-breaking seasons, with a high number of plants found across the Southern Tablelands this summer, NP&WS reportr
Saving our Species ecologist Erika Roper said recent summer rains have prompted an explosion of these miniature raspberry-scented orchids in the bush near Nerriga and Braidwood.
'Before the fires there were only a handful of known plants and historical records, but since 2020 we have discovered more than 300 plants spread over 3 sites,' Ms Roper said.
'The number alone is impressive but even more so when you consider just how hard it is to find this plant.
'Like many orchids, midge orchids spend much of the year below ground as a tuber, before putting up a single narrow stem that develops a flower spike.
'The stem looks exactly like a chive, the kind you grow in the veggie garden, so even when you know exactly what you are looking for, it's still tricky surveying for this tiny plant.
'Fortunately, orchid-spotting is my superpower and I've found some emerging stems that are only around 1 centimetre high.
'We're into our third summer of soaking rains and we think that is why we are seeing such a response from this and other threatened and common midge orchid species in the area.
'The fires also reduced many of the threats to this species, such as grazing by herbivores, allowing the orchids to live up to their name and put on a superb show.
'Coloured varying shades of dark pink and purple with fringed 'petals', they are one of the prettiest orchids around, but most people have never seen or even heard of it.
'Last month's surveys also found new plants growing in unburnt areas, including along wombat tracks and roadsides, and we have installed temporary cages to protect these individuals from damage.
'It's just amazing to see these extremely rare and pretty unusual looking plants bouncing back.
'It really reconfirms the extraordinary and resilient biodiversity that can be found in this part of the world,' Ms Roper said.
The Saving Our Species program is investing almost $100,000 into orchid conservation in the Illawarra and surrounding regions. This funding supports ecologists like Erika to commit resources towards threat control, surveying and monitoring, all of which help secure species like the superb midge orchid into the future.

NPWS Investigating Ongoing Vandalism At Greenfield Beach
March 24, 2022
Authorities are appealing for information following vandalism at the popular Greenfield Beach Picnic Area in Jervis Bay National Park. Nathan Cattell, Acting Area Manager with the NSW National Parks and Wildlife Service (NPWS) said that over recent months vandalism at this family-friendly picnic area has hit unprecedented levels, with regular reports of damage and anti-social behaviour.
'We are working with the NSW Police to try to control this behaviour that is stopping others from enjoying the site,' Mr Cattell said.
'Damage to visitor facilities, including destroying the toilet block and sinks not only costs thousands of dollars to repair but also leaves the area out of action while we clean up.
'Broken glass and smashed bottles are also littering the site which makes the area unsafe for people who are having a picnic or stopping off along their bushwalk.
'The time to repair vandalised facilities takes staff away from other critical jobs including maintenance of walking trails, other visitor facilities and conservation work.
'NPWS is working closely with the local Police and both agencies will be stepping up patrols to control this anti-social behaviour and find who is responsible.
'Local residents have been very helpful in providing information as part of this investigation and we ask anyone with information to please come forward.
'This is not a one off. There has been consistent vandalism at the site prompting NPWS to install remotely active CCTV cameras and other measures to curb this behaviour.
'Jervis Bay National Park is world renowned, attracting visitors from overseas and Australia and we want them to enjoy the area's natural beauty and not see broken, vandalised facilities,' Mr Cattell said.
This deliberate damage at Greenfield Beach is a criminal offence, attracting fines of between $500 and $10,000.
People with any information regarding the vandalism are urged to call NPWS at Ulladulla on 02 4454 9500, or Crime Stoppers on 1800 333 000.
Scientists Find Climate Main Factor Behind Dropping Water Levels At Thirlmere Lakes
March 24, 2022
An extensive research program into fluctuating water levels at Thirlmere Lakes has confirmed that climate variations were largely responsible for the ancient lake system's decline in water levels over the last decade. The 4-year study found no direct links between the drying of Thirlmere Lakes and the nearby coal mine but could not rule out a smaller (relative to climate) impact on water levels from mining.
The Thirlmere Lakes is a group of waterways in Wollondilly, south of Sydney, in the Thirlmere Lakes National Park that includes Lake Gandangarra, Lake Werri Berri, Lake Couridjah, Lake Baraba and Lake Nerrigorang.
The mystery of the drying of the lakes, which are thought to be 15 million years old, has been investigated for nearly a decade.
Dr Peter Scanes, Acting Director of Water, Wetlands and Coasts at the Department of Planning and Environment (DPE), said the research confirmed factors like rainfall and evaporation were responsible for most of the recent drying and water loss at the freshwater lakes.
'The drying has been increased by the recent droughts but our investigations of sediment cores taken from the lakes also found that the lakes have dried before,' Dr Scanes said.
'In fact, there was a major drying period around 12,000-21,000 years ago. The last 120 years of historical records also indicate that the Lakes have dried intermittently.
'Our scientists also looked at the underlying geology of the 5 lakes. Those studies found the lakes are like leaky bathtubs. They fill with water after rain and dry out on the surface from the sun but they can also leak into the groundwater.
'Understanding the dynamics of how the lakes work is important for both scientists and the local community, who have been very interested in what is behind the recent drop in water levels.'
The $1.9 million research program was funded by the NSW Government and included scientists from the department, the University of NSW, the University of Wollongong and the Australian Nuclear Science and Technology Organisation (ANTSO) with support from the NSW National Parks and Wildlife Service.
The researchers looked at the lake system's sensitivity to external influences, the interaction between surface water and ground water, how water flows into and out of the lakes as well as its sediments and underlying geology.
Dr Scanes said researchers found no direct connection between Thirlmere Lakes and a nearby coal mine.
'Relative to climate, the impact of mining and groundwater extraction would be smaller, given climate factors are responsible for between 83 to 98% of water level fluctuations in recent times,' Dr Scanes explained.
'However mining impacts could not be ruled out as there was not enough data collected prior to mining occurring nearby. We therefore have no yardstick for comparison to conditions before mining took place.'
A 2012 Thirlmere Lakes Inquiry report by an Independent Committee speculated that the most recent changes in the water levels were due to climatic variations such as droughts and floods. However these earlier studies did not have access to the detailed data on surface water, groundwater, sediments and geology collected in the current program.
A review of those findings by the NSW Chief Scientist and Engineer in 2013 agreed more research was needed into how the lake system works. This resulted in the $1.9 million Thirlmere Lakes Research Program launching in 2017.
The findings of the Thirlmere Lakes Research Program can be found online.
Following significant rainfall events in June 2016, February 2020, March 2021 and more recently, Thirlmere Lakes are potentially at their highest levels for the last decade.
- Water into Thirlmere Lakes is primarily rainfall run-off
- The main cause of water loss from the lakes is evapotranspiration
- A smaller proportion of water is also lost from each lake to shallow groundwater.
- The groundwater loss is different for each lake.
- Thirlmere Lakes have had five major filling events due to rain over the last 6 years – June 2016, February 2020 and March 2021, January 2022, March 2022.
- It is likely the lakes will continue to swing between low and higher water levels depending on drought and major rainfall events.
In the longer term mining impacts on regional groundwater may affect lake water levels by reducing inflows to lakes and increasing the hydraulic gradient (water flow path) away from the lakes.
Thirlmere Lakes National Park is part of the Greater Blue Mountains World Heritage Area.
Hunter Diversification Panel No Place For A Coal Mining Lobbyist Environmentalists State
March 25, 2022
The appointment of a NSW Minerals Council representative to an expert panel that is meant to oversee the Hunter Region’s diversification beyond coal risks is undermining the work the group was established to do, according to Lock the Gate. The Alliance says the appointment of a member of the coal lobby interferes with the panel’s purpose and creates a risk that some of the transition funding may end up in the hands of multi-national coal mining companies.
The NSW Perrottet Government yesterday revealed the eight person interim expert panel that would guide spending from the $25 million per annum Royalties for Rejuvenation fund.
The Royalties for Rejuvenation interim Hunter Expert Panel members are;
- Amy Cooper, Hunter Valley Wine & Tourism Association
- Bob Hawes, Business Hunter
- Deb Barwick, NSW Indigenous Chamber of Commerce
- Ivan Waterfield, HunterNet
- James Barben, NSW Minerals Council
- Joe James, Hunter Joint Organisation
- Sarah Withell, Upper Hunter Mining Dialogue
- Warwick Jordan, Hunter Jobs Alliance
The fund was created to ensure coal mining communities have the support they need to develop other industries in the medium and long-term.
Legislation was introduced into the NSW Parliament this week to create the Fund and establish the Expert Panels - this will be made available through the Mining and Petroleum Legislation Amendment Bill 2022.
In an address given in parliament about the bill The Hon. Paul Toole stated;
The Royalties for Rejuvenation fund delivers on a key commitment to support the growth of new jobs and industries in traditional coalmining communities. That will not happen overnight but requires detailed, long-term planning to ensure the regions continue to have growth industries that offer skilled, well-paying jobs. The new section of the Act specifies the purpose of the fund:
… to alleviate economic impacts in affected coal mining regions caused by a move away from coal mining by supporting other economic diversification in those regions, including by the funding of infrastructure, services, programs and other activities.
Locals are best placed to understand their community's needs and develop emerging opportunities. That is why the bill provides for the Minister to establish expert panels to advise the Minister and make recommendations about the payments from the Royalties for Rejuvenation fund. That will ensure that regional communities and industries play a central role in shaping the fund's priorities through support and provision of comprehensive advice that will guide long-term decisions on the fund's investment. The bill establishes a requirement to review the fund after three years to consider whether the fund is meeting its policy objectives and whether the provisions in the bill remain appropriate. That review period will give the Government time to see how the fund is operating and provide an opportunity to make improvements or adjustments to the legislative framework if required.
However, a Lock the Gate Alliance spokesperson, Georgina Woods, has stated that a member of the Minerals Council on the panel would compromise its ability to make objective recommendations that diversified the Hunter’s economy.
“It makes no sense to appoint a coal mining lobbyist to a panel that is meant to advise on the best way to diversify the Hunter’s economy beyond coal,” she said.
“We are calling on NSW Deputy Premier Paul Toole to remove the NSW Minerals Council’s representative, and to promise that none of this $25 million will go to coal mining companies.
“We’re pleased the government is moving swiftly to get the Hunter on the road to renewal, but the coal mining industry already dominates the political and economic landscape in the Hunter. It doesn’t need any more influence. We need a panel that gives community, environment, Indigenous and local business groups space to plan for the diversification of the region beyond coal.
“The coal mining lobby is yet to acknowledge that expanding coal is completely at odds with global efforts to prevent catastrophic climate change.
“At this crucial moment, when we finally have funding to help diversify the Hunter’s economy, the NSW Perrottet Government must ensure industries and communities other than coal mining have space to grow and plan - without the coal lobby breathing down their necks.”

Little Penguins To Benefit From CSIRO’s New Invasive Weed Solution
March 24, 2022
The CSIRO reports that Little penguins in Victoria will be among the native species to benefit from a new biocontrol solution to tackle the invasive coastal weed ‘sea spurge’, which will be released in Port Campbell National Park by Australia’s national science agency, CSIRO, and Parks Victoria today.
CSIRO researchers have found that the fungus, Venturia paralias, specifically attacks the invasive coastal weed called sea spurge (Euphorbia paralias), which threatens nesting sites of native species including little penguins (Edyptula minor), as well as impacting on the wider coastal ecosystem. Current control methods include removing the weed by hand or chemical sprays.
The fungus will be released by CSIRO and Parks Victoria at the world-renowned London Bridge, a natural offshore arch in Port Campbell National Park. The park is a popular tourist destination, with visitors coming to see the pristine coastline, Twelve Apostles and little penguins returning to their beach nests after fishing.

CSIRO scientist Dr Gavin Hunter said sea spurge is problematic for nesting shorebirds, including penguins, as the weed can alter sand dune structure and displace vegetation which could negatively impact nesting sites of shorebirds.
“The weed also has a sap which can cause irritation to animals as well as humans,” Dr Hunter said.
“Sea spurge grows along Australia’s southern coastline and is a concern for coastal ecosystems. We’re hopeful the biocontrol agent will help reduce the dense weed from penguin nesting sites at Port Campbell, and many other beaches along the coastline where the weed occurs.
“There are many challenges with current methods for removing sea spurge so finding a biocontrol agent for the weed was important to complement existing management strategies of hand pulling and chemical sprays that are very labour intensive, costly, and cannot easily be deployed in difficult-to-access beaches.”
CSIRO research technician Ms Caroline Delaisse will release the biocontrol agent at Port Campbell and said the fungus was originally found on the Atlantic and Mediterranean coast of France causing leaf and stem lesions on sea spurge plants.
“The fungus was isolated from these diseased plants and initial tests to explore its host range were performed in France. Following positive results from these tests, the fungus was imported to CSIRO’s quarantine facility in Canberra and studied extensively," Ms Delaisse said.
“Our research found that the fungus is highly specific towards sea spurge. Based on our results, the fungus was approved by the regulator for release in Australia.”

Parks Victoria manages around 70 per cent of Victoria’s coast and is helping CSIRO release the fungus at several sites, in addition to Port Campbell National Park.
Parks Victoria Program Leader for Marine and Coasts Mr Mark Rodrigue assisted in the first releases of the fungus in Victoria and said this was an exciting advancement in weed control that would help protect the health of Victoria’s beautiful coast and native animals, such as little penguins and plants that depend on beach and dune habitats.
“If it successfully establishes, the biocontrol will be particularly important for managing this highly invasive weed in the more remote parts of the coast where access is very difficult for manual or chemical control,” Mr Rodrigue said.
“CSIRO has paved the way for land managers like Parks Victoria and volunteers to safely target areas of sea spurge infestation, with solid science and comprehensive guidelines developed to support us.”
A prolific seed producer, a mature sea spurge plant can produce up to 20,000 seeds per year and can grow anywhere on the beach above the high-water mark, taking over sand and dune vegetation.

This project has been financially supported by the NSW Government as part of nearly $500,000 in funding targeting four weed species including sea spurge.
Sea spurge is an introduced plant from Europe that has invaded coastal ecosystems from Geraldton north of Perth in Western Australia through to the mid north coast of New South Wales and around Tasmania’s coastline.
CSIRO is calling for volunteers to help with the biocontrol release program on beaches infested with sea spurge in Victoria and Tasmania. To participate in community releases, seek approval from the land manager or owner in the first instance and then contact CSIRO scientists Gavin Hunter (email@example.com) or Caroline Delaisse (firstname.lastname@example.org).

Roadmap Pinpoints Research Required For Smooth Transition To Renewables
March 25, 2022
Australia’s national science agency, CSIRO today released a Roadmap highlighting the research required to continue Australia’s transition to a more secure and affordable electricity system, showing that innovation can drive the integration of renewables.
The Roadmap was developed in collaboration with the Australian Energy Market Operator (AEMO), and is based on input from leading Australian and international system operators and research agencies from the Global Power System Transformation (G-PST) Consortium.
The Consortium adapted key research questions to the Australian context, with the goal of supporting Australia’s energy transition in the long-term interests of consumers. The research areas they identified address the challenge of rapid change faced by Australia’s National Electricity Market and Wholesale Electricity Market.
Australia’s electricity systems face several key challenges, including ageing infrastructure, increasing complexity, and the need for investment in transmission and distribution.
The Roadmap summarises the outcomes of nine individual research plans, including their criticality to Australia’s energy transition, which research should be prioritised and how the research could form individual programs.
The key research topics are:
- Inverter design
- Stability tools and methods
- Control room of the future
- Restoration and Black Start
- Architecture (Australian-specific)
- Distributed Energy Resources (DERs) (Australian-specific)
- DERs and Stability (Australian-specific)
CSIRO’s Energy Systems Research Director, Dr John Ward said the Roadmap could help forge a clear pathway to the integration of low emissions electricity.
“Across the energy system we are seeing a significant increase in renewable-generated electricity, combined with an increase in electricity requirements such as in transport, buildings, manufacturing and mining,” Dr Ward said.
“The cost of renewable energy is no longer the challenge – integrating renewable energy securely and efficiently into our electricity systems, and ensuring we have the right operational tools and capabilities in place, is what we need to solve.
“Australia has some of the world’s highest levels of rooftop solar, which means this integration challenge extends throughout our electricity system – from the largest generators through to efficiently integrating ‘distributed energy resources’ (such as solar and electric vehicles) into our homes and businesses.”
The Roadmap targets areas that will ensure ongoing energy security and reliability for Australian consumers, and an efficient and effective investment in infrastructure.
“The role of research throughout this transition is vitally important and Australia has the opportunity to lead the charge,” Dr Ward said.
Following industry consultation, CSIRO will use Roadmap priority areas to create technological steppingstones for further innovation while remaining adaptable to inevitable further change.
AEMO Executive General Manager Operations, Michael Gatt, said the research program targeted the increasing complexity facing power system operators with the rapid transition to inverter-based variable renewable generation.
“Australia is investing in renewable energy at a faster rate per capita than any other country. As Australia’s energy market operator, we’ve seen average renewable energy contribution increase to approximately 40 per cent of total or underlying demand, along with five-minute interval peaks above 60 per cent. In addition, consumer rooftop solar PV is pushing grid-scale generation out of the market under certain day-time conditions, setting minimum operational demand records across the country,” Mr Gatt said.
“The pace and scale of this transition is extraordinary. It demands new approaches to power system operations including tools, technologies, process and platforms, which complement network planning, and market and regulatory reforms.
“AEMO’s role is to design and operate a sustainable energy system that provides safe, reliable and affordable energy today, and to enable the energy transition for the benefit of all Australians. The CSIRO G-PST Research Roadmap, together with the AEMO Engineering Framework and upcoming Operations Technology Roadmap, is where the rubber hits the road in terms of providing a guide for government, industry and academia to work together to deliver a major step in achieving a net-zero emissions economy by 2050 – engineering net-zero energy systems.
“We need timely, multidisciplinary expertise and collaboration to identify and resolve the engineering and system issues involved in decarbonising Australia’s power systems. This is how we will keep the lights on for consumers while enabling an orderly transition to a safe, reliable and affordable net-zero energy future.”
The G-PST consortium intends the Roadmap to create a meaningful and holistic solution to the Australia’s energy transition.
CSIRO will soon be seeking input for phase 2 of this work.

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.
