Seasonal Bushfire Outlook: Spring 2026

The Bushfire Seasonal Outlook for Spring was released August 19 2026 by the Australasian Fire and Emergency Service Authorities (AFAC), with fire authorities predicting a heightened risk of fire across northern and south-eastern NSW, south-east Queensland, north-eastern Tasmania, parts of WA, SA and Victoria, and large parts of the NT.


Below average rainfall has increased bushfire risk potential across northeast and eastern Tasmania, as well as parts of Victoria. In contrast, above average fuel loads and dry soil conditions are contributing to elevated fire risk across parts of WA.

AFAC CEO Rob Webb said: “This outlook highlights a heightened risk of fire across several parts of the country, driven by a combination of dry conditions in the east and increased fuel loads through parts of central and northern Australia. The variety of risk factors across different regions reinforces the need for communities to understand their local conditions and prepare early."

"While some areas are facing an elevated risk of fire this spring, bushfires can still occur in regions with a normal seasonal outlook. Communities are encouraged to stay informed, monitor local conditions and follow advice from their fire and emergency services as the season unfolds."

The areas marked in red on the map represent an increased risk of fire, largely driven by below average rainfall and dry conditions.

The Seasonal Outlook is the culmination of a complex analysis by expert fire specialists across Australia, and climate prediction and fire weather experts from the Bureau of Meteorology.

Crossbench secures 2040 deadline for renewable energy CGT Concessions, boosting certainty for Foreign Investment 

Thursday August 20 2026

The Australian government has extended a capital gains tax (CGT) concession for foreign investors in wind, solar and battery storage assets by a further decade, pushing the deadline from 2030 to 30 June 2040.

The extension comes after pressure from the Greens and crossbench MPs during debate on the enabling legislation in federal Parliament.

The amendment lessens a broader package of CGT reforms Treasurer Jim Chalmers first proposed in the 2024-25 budget, aimed at clarifying and broadening the range of Australian assets, including renewable energy infrastructure, telecommunications, rail, ports and airports, on which foreign residents are liable for capital gains tax when they sell.

Legislation formalising those changes was introduced to Parliament in early July 2026, offering a 50% discount on the new CGT liability for renewable energy assets through to 2030 as a transition measure.

The amendment passed this week extends that 50% discount period to 2040, specifically for the renewables sector.

Crossbench MPs have welcomed news the Albanese government has responded to their concerns and will extend the CGT concession from 2030 to 2040 for foreign investment in renewable energy.

The Government’s proposed changes risked undermining investment certainty and slowing the rollout of much-needed renewable energy infrastructure.

This important extension provides investors and project developers with greater certainty and a more realistic timeframe to plan, finance and deliver renewable energy projects. It will help protect the pipeline of investment needed to secure the clean energy economy we need to meet Australia’s renewable energy goals.

The government’s initial proposal for a 2030 phase-out of CGT concessions would have created additional pressure on projects already facing long development timelines, higher costs and a need for stable and predictable investment settings.

A 2040 transition recognises the realities of financing and building renewable energy infrastructure and strikes a better balance between the government’s tax objectives and the urgent need to maintain investment in Australia’s renewable energy rollout.

Warringah MP Zali Steggall said on Thursday:

“This is a welcome step that gives investors and project developers greater certainty, but we cannot afford to slow Australia’s clean energy build-out.

“Australia needs significant new generation, storage and network investment through to 2050 – and around 70 per cent of clean energy capital comes from foreign sources.

“I will continue to push for a statutory review in 2035 to assess whether a further extension of the CGT concession is needed to keep Australia on track to meet its renewable energy goals and achieve net zero by 2050.”

Nicolette Boele, MP for Bradfield, said:

"This is a welcome result for Australia's clean energy industry and, frankly, for anyone who pays a power bill. Investors now have a runway out to 2040, long enough to finance and build the solar farms, wind projects and batteries that put downward pressure on prices.

"We were staring down a fire sale of renewable assets before 2030 and a freeze on everything after it - a self-inflicted wound on our energy economy.

"It took sustained pressure from the crossbench and from industry to get here. This is what it looks like to bring our tax laws into line with an economy fit for the 21st century."

Mackellar MP Dr. Sophie Scamps stated:

“The crossbench has been crucial in securing this important amendment, which will ensure investment in clean energy continues - something which is essential to Australia’s future energy security.

“I was pleased to see the Government accept the extension for the CGT concessions to 2040 as proposed in the amendment I circulated to better reflect realistic investment timeframes.”

Dr. Monique Ryan, MP for Kooyong, stated:

“A mature discussion about CGT reform is a conversation we had to have, and I congratulate the government for further strengthening Australia's CGT regime.

“Most importantly, the crossbench together with the clean energy sector is set to secure a significant victory today when it comes to extending the timeframe in which concessional rates of CGT are applied to investment in nation-shaping energy generation and storage assets.

“These tax reforms were needed to provide certainty to investors. I'm pleased the government has agreed to adopt this practical improvement to helps accelerate our energy transition towards net zero.”

Allegra Spender, MP for Wentworth, said:

I’m really pleased that the government has listened to the crossbench and stakeholders and improve this legislation, speed the energy transition and avoid sovereign risk. It’s always important that changes to complex legislation are road tested before implementation and pleasing when we can work with stakeholders to improve policy settings.”

Crossbench MPs demand broad review and ambitious reform of Australia’s central climate policy

Crossbench MPs have responded to the Federal Government publishing its consultation paper into the Safeguard Mechanism, as part of the statutory 2026-27 review.

In the most recent year of data, the Safeguard Mechanism drove a 2.4% reduction in emissions at the covered facilities. This represents progress – but emissions are not reducing fast enough. All additional emissions cuts were through the use of offsets.

There are a number of significant limitations of the Safeguard Mechanism, including an over-reliance on offsets, insufficient constraints on fossil fuel expansion and ongoing conflict with the Fuel Tax Credit scheme, which completely undermines any policy signal for large miners to decarbonise.

The 2026-27 review period provides an important opportunity to identify and fix the limitations in the Safeguard Mechanism. The review must be broad and ambitious if Australia is going to achieve its emissions targets and develop thriving green export industries.

The Safeguard Mechanism is the central climate policy in the Federal Government’s toolkit, governing emissions at Australia’s largest-emitting facilities. It covers nearly a third of Australia’s total emissions.

In a joint submission to the Climate Change Authority’s review of the Safeguard Mechanism and Australia’s broader climate progress, crossbench MPs will make the following recommendations:

  • Recommendation 1: Align Safeguard Mechanism decline rates with the upper bound of Australia’s 2035 emissions reduction target.
  • Recommendation 2: Support industries of the future by applying steeper decline rates to coal and gas.
  • Recommendation 3: Consider how Safeguard Mechanism reforms can support and drive a transition to a Border Carbon Adjustment to support our industrial competitiveness.
  • Recommendation 4: Strengthen the mitigation hierarchy to drive greater on-site abatement and less reliance on offsets.
  • Recommendation 5: Strengthen the rules around new entrants to the Safeguard Mechanism.
  • Recommendation 6: Reform the Fuel Tax Credit Scheme which continues to undermine the Safeguard Mechanism.
  • Recommendation 7: Consider how Safeguard Mechanism reforms can support accelerated rollout of renewable energy and storage.
  • Recommendation 8: Improve measurement of methane emissions

Kate Chaney MP, Member for Curtin, said:

“The Safeguard Mechanism is such an important policy in our country’s mission to contribute to a safe climate and grow a thriving, sustainable economy. This review is a significant opportunity to improve this crucial policy; the Government must be willing to consider the whole range of issues and implement ambitious solutions.

“The Safeguard Mechanism is being completely undermined and undercut by the Fuel Tax Credit Scheme. The Fuel Tax Credit Scheme incentivises miners to continue to burn diesel and overwhelms the Safeguard Mechanism’s policy signal to decarbonise. We can’t meet our emissions targets with our foot on the accelerator and brake at the same time. There are sensible reform policies that would only impact about 18 of the largest, highly profitable companies – without touching the credits provided to farmers and small users of diesel.

“The role of the Safeguard Mechanism is not just to drive emissions reductions, it’s also to support the growth of the green export industries of the future. This review must consider how the Safeguard Mechanism can support and drive a transition to a border carbon adjustment – to support our vital industries like steel and aluminium.”

Nicolette Boele MP, Member for Bradfield, said:

“Right now, the Fuel Tax Credit Scheme gives mining companies a bigger reason to burn diesel than the Safeguard Mechanism gives them to cut emissions. The Safeguard Mechanism prices carbon at around $38 a tonne. The Fuel Tax Credit works like a carbon price of -$199. We are in an absurd situation where mining companies have five times more reason to keep burning diesel than to cut their emissions.

"The Safeguard Mechanism currently lumps all industries together into one scheme. Whilst we want an internationally competitive resources sector, the Safeguard Mechanism must recognise that pure play fossil fuel production is a sunset industry in Australia and reflect that by requiring fossil fuel industries to reduce emissions faster than the industries we want to keep."

Zali Steggall MP, Member for Warringah, stated:

“The Safeguard Mechanism only works if we can trust the data behind it. As it stands, methane emissions from coal, oil and gas facilities are too often under-estimated, creating a real risk that reported reductions aren't genuine.

"The Albanese government must strengthen the integrity of the Safeguard Mechanism by requiring better methane measurement from big polluters. Better data means better policy, genuine emissions reductions and more confidence that Australia's climate targets are being met."

Dr. Sophie Scamps MP, Member for Mackellar, said:

“Australia cannot offset its way out of the climate crisis. The Safeguard Mechanism was designed to cut pollution from our biggest emitters, yet emissions are not falling fast enough and too much of the progress is coming from offsets rather than real reductions. If we are serious about a safe climate and a strong clean economy, big polluters must cut emissions at the source.”

Allegra Spender MP, Member for Wentworth said:

“The reformed Safeguard Mechanism was a big step forward, but the job isn't finished. Right now, too much of the emissions reduction we're seeing isn't coming from companies actually cleaning up their operations. 

If we're serious about hitting our 2035 target, the Safeguard needs to require real, on-site abatement — not just cheap offsets.

“The Safeguard only covers around 30% of Australia's emissions, so however well we tune it, it can't get us to our 2035 target alone. Much more is needed, particularly across transport and agriculture. An economy-wide carbon price remains the cheapest way to get us to the top of our 2035 target.”

"The Safeguard Mechanism is being asked to do the lion's share of the climate lifting. The Government told us we didn't need a climate trigger in our national environment law because the Safeguard already had it covered. And yet, over the last three years, we've seen coal mine after coal mine expanded or extended. The scheme simply isn't adequately constraining fossil fuel expansion while only measuring scope 1 emissions. Meanwhile the far bigger climate cost of burning coal and gas goes unaccounted for."

Framework for NSW Data Centres Released

On Monday 17 August 2026 the NSW Government announced its framework to support what it stated is ''responsible investment in data centres, while ensuring communities, businesses and the broader economy benefit from this important infrastructure''. The government stated earlier this year there are already 90 data centres operating in NSW, once double counting associated with projects developed through multiple stages is accounted for. 


A Sydney Data Centre Map states there are 106 in Sydney - with the nearest one to our area, NEXTDC, being located at Macquarie Park among a hub of others.

Sydney Data Centre Map - screenshot showing clusters of data centre hubs

On March 27 2026 the Minns Government announced 15 data centre projects will progress through the Investment Delivery Authority (IDA), as it released its 'NSW Data Centre Consultation Paper' to steer what it called 'the sustainable development' of the sector in New South Wales.

As of July 2026, there were 19 projects in the State Significant Development (SSD) planning pipeline valued at $50.3 billion.

The government stated data centres now account for 12% of all non-residential building investments.

Once built, data centres benefit the NSW Government's finances primarily through avoided public infrastructure costs, direct and indirect state taxes, and developer-funded utility augmentations rather than direct operational subsidies.

Ongoing financial benefits are limited. Operational staffing needs are relatively small because modern facilities are heavily automated.

A consensus on community platforms notes that because most major operators are foreign-owned, the majority of net corporate profits leave the domestic market.

Senator David Pocock stated in June 2026['We Cannot let Data Centres be a repeat of the Great Gas Scam']:

''Data centre construction is sucking up our already scarce construction industry workforce, which will no doubt further hamper efforts to hit our housing targets. While they do generate employment in the construction phase, the ongoing direct employment benefits are minimal which is a huge concern given that every time I’ve questioned the responsible cabinet minister about AI job losses he has pointed to investment in data centres. AirTrunk employs just 259 people on a permanent basis, CDC Data Centres 356 people and NextDC 381 according to their own reports. 

We also need to ask the question - what is this all for? There are undoubtedly many exciting applications of AI. But it’s also a technology that has the potential to totally disrupt society, and even poses an existential risk to us as a species. 

AI job losses in Australia have already topped the tens of thousands and Jobs and Skills Australia Commissioner Barney Glover has said job losses are expected to be more than 600,000.

The AI boosters will say that these hundreds of thousands of unemployed Australians will quickly find other newly-created jobs in the new AI-powered economy. But from what I’ve heard listening to experts this may be wishful thinking as AI and robotics combine to replace human labour. 

Why are we rushing to embrace data centres and the AI future they enable without answering these questions and ensuring we will actually benefit from them?

Australia should embrace new technology that improves our lives and helps us live within the bounds of ecological limits. We should welcome investment that creates value and helps build our future economy, but we should also learn from our past.

If multinational tech giants are going to use Australian land, Australian energy, Australian water and Australian workers to build the infrastructure that powers the AI revolution, then Australians deserve a fair return.''

Australians state their concerns long-term operations will put continuous pressure on local water supplies and electricity grids, and cause higher utility costs for local communities and a reduction in available water if not properly regulated, have also not been clearly addressed.

By late 2025 data centres were using approximately 3.5 billion litres of Sydney's drinking water supply per year, which was less than 1 per cent of total demand, but still a high amount in a country known for its droughts and in a city which has experienced water restrictions during prolonged drought periods in the past. 

Residents want to know; when that scenario arises again, will the data centres have priority, or communities?

With climate change adding extra impetus for access to water during bushfire periods, which have commenced in July in NSW since the 2019-2020 Black Summer fires, and as many have witnessed the firestorms impacting Europe, the US and Canada in recent weeks, with locals and NSW equipment deployed to assist, residents of New South Wales wish to scrutinise any state or commonwealth plans for Australia's use as a data centre hub, especially in regards to water use. 

The UN stated on June 4 2026:

''Data centres, the global infrastructure powering AI, could consume 945 terawatt-hours of electricity annually by 2030 – nearly triple the combined annual electricity use of Pakistan, Bangladesh, and Nigeria, countries collectively home to more than 650 million people. 

On top of the carbon footprint, every unit of electricity used by data centres also carries a “water footprint” for cooling and energy production, and a “land footprint” associated with power generation and supply chains. 

According to a new study from UN University (UNU), AI-related water consumption could equal the basic annual domestic needs of 1.3 billion people by the end of the decade, while its land footprint may exceed 14,500 square kilometres — roughly twice the size of the Jakarta metropolitan area.''

''The NSW Data Centre Policy Framework will make sure future data centre investment is matched with increased investment in renewable energy and water infrastructure.'' the government said on Monday

''It establishes clear expectations for data centre proponents, with world-class energy, water and environmental standards, meaningful community consultation and appropriate contributions towards the infrastructure needed to support growth.''

''The framework sends a clear signal that NSW supports data centre investment that creates jobs, fosters innovation, grows the economy and delivers benefits for communities.''

''Beyond powering technologies used in the home and workplace, their computing power and storage also drive many of the services that communities rely on every day, including healthcare, emergency services and banking.''

''Investment in the sector in NSW has been increasing at around 75 per cent per year on average over the three years to December 2025. This growth, combined with the transformation of NSW’s energy system, is a key reason we have avoided recession.'' the government stated

The NSW Data Centre Policy Framework states under 'Forecast energy and water demand from data centres:

'The Australian Energy Market Operator (AEMO) forecasts that energy consumption from data centres will double from 5% of NSW’s grid-supplied energy in 2026 to 11% by 2030. This growth is forecast during the same timeframe that around 7 gigawatts (GW) of coal-fired generation is scheduled to retire in NSW.

Oxford Economics, which prepared AEMO’s forecast on data centres, estimates 6 in every 7 megawatts (MW) of data centre connection requests are phantom demand. 

Consultation with energy utilities suggests 20% of data centre applications in their connections pipeline are likely to proceed. While these figures differ slightly, they highlight that the share of data centre proposals likely to proceed to construction is low.

Water demand is also expected to rise in the coming decade, but the extent of this increase is uncertain. There is agreement that modelling approaches between the water and energy sectors need to be aligned, including in relation to ramp up periods and phantom demand.

Most investors in data centre development also have targets to reach net zero emissions for their operations by 2030 or 2035. This implies that there is an opportunity to collaborate with industry to increase the supply of renewable energy and lower carbon emissions.'

The government's 'NSW Data Centre Policy Framework' outlines how this growing digital investment will be used to drive the energy transition and support the state economy. The framework includes:

The NSW Data Centre Guidelines

Under the new framework, the government states data centre builders wanting access to a streamlined assessment process will need to comply with the NSW Data CentreGuidelines.

They require specific performance measures to achieve six principles:

  1. Apply world-class environmental and efficiency standards
  2. Impose no net cost to consumers and communities
  3. Fund additional supply of water and energy
  4. Enhance local community infrastructure and amenity
  5. Invest in future industries across the supply chain
  6. Demonstrate a commitment to training and skills to support jobs.

''Projects that meet the performance measures associated with the above principles will receive a commitment to have their proposed developments assessed within 75 days, while still meeting all planning, environmental and community consultation standards'. the government said

'This commitment is supported by concurrent changes being made to Independent Planning Commission processes to further streamline key project assessment.

The Investment Delivery Authority will also convene an industry collaboration event to connect energy and data centre investors.''

The government stated the Guidelines will be reviewed annually to ensure they remain fit for purpose and reflect advances in technology and changes in the industry.

Regulatory reform to ensure equitable cost recovery for energy infrastructure

Under the second pillar of the framework, the NSW Government will make regulatory changes to:

  • ensure that data centres pay for the electricity network upgrades they require, so that extra costs aren’t shifted to households and small businesses,
  • support more coordinated and efficient planning of the electricity network, and
  • support implementation of the measures in the Guidelines.

The government stated ''We have introduced legislation to enable these reforms and begin consultation on the detailed implementation today.''

An IPART review to consider the full recovery of costs of water provision to data centre customers

''The NSW Government is commissioning IPART to undertake a review of the water pricing framework for data centres.'' the government said

''The review will consider how water pricing can reflect the full costs associated with servicing data centres, ensuring other water users on the network are protected and the impacts of drought and water scarcity are appropriately managed.''

Office of AI

Alongside the NSW Data Centre Policy Framework, the Government will establish the new Office of AI in The Cabinet Office to strengthen and accelerate the response to the opportunities and challenges presented by artificial intelligence.

The new Office of AI will work closely with Digital NSW, which will continue to lead coordination of government investment in the digital, cyber and data foundations needed to support AI adoption. It will also work with public sector unions to ensure AI supports workers, strengthens capability and is implemented responsibly across the public sector.

The NSW Government will continue working closely with the Australian Government and other states and territories to ensure future reforms establish a nationally coherent policy framework.

There are 19 data centre projects valued at $50.3 billion in the State Significant Development pipeline. This is in addition to more than 60 data centres that are already operating or under construction.

Minister for Climate Change, Energy and the Environment, Penny Sharpe said:

“As demand for data centres increases, NSW will ensure the infrastructure needed to support them grows with it.

“These reforms will make sure data centre growth drives investment in renewable energy, while holding operators to the highest air quality standards.”

Treasurer Daniel Mookhey said:

“The scale of data centre investment being considered in NSW presents a unique opportunity.

“Data centres need power and there are renewable projects seeking investment.

“Connecting the two means this booming digital industry can help pay for the new energy and water infrastructure that our economy needs.

“This world-class framework provides the certainty that both investors and – importantly – the community need.

“NSW is a premium destination, so we are setting a high bar.”

Minister for Planning and Public Spaces Paul Scully said:

“Data centres are the enabling infrastructure for modern economies and communities.

“These Guidelines provide clear expectations, improving transparency and providing certainty for both communities and investors.

“We’ve struck the right balance, maintaining strong environmental standards to safeguard our water and energy future while supporting faster and more certain planning assessments for data centres which protect the interests of communities while delivering them benefits.”

Minister for Customer Service and Digital Government Jihad Dib said:

“Artificial intelligence is increasingly part of our everyday lives and we have a strong framework within the NSW Government to ensure it is used safely and responsibly.

“We are building on these strong foundations through a whole of government approach and Digital NSW will work closely with the new Office of AI to support NSW to safely navigate emerging AI technologies and harness new opportunities to benefit the community.”

Minister for Industry and Trade Anoulack Chanthivong said:

“Data centres are a vital part of the digital economy and NSW must remain an attractive destination for this growth.

“These Guidelines provide greater certainty for investors while making clear that major projects need to contribute to the infrastructure and resources they rely on.

“The opportunity goes well beyond the construction of new facilities. Data centres can help grow future industries, from education and cybersecurity to advanced manufacturing, medical technology and renewable energy.”

Minister for Water Rose Jackson said:

“Data centres are becoming an increasingly important part of our economy, but we need to make sure their growth is supported in a way that protects the long-term security of our water system.

“These Guidelines direct data centres to use water efficiently, prioritise recycled water where possible, and contribute to the additional water supply needed to support future growth in NSW.

“By preserving drinking water supplies for communities and ensuring the costs of servicing new demand are not placed on other customers, we can support investment while maintaining confidence in the sustainability of our water resources.”

Background: Electricity and Water Use -  Water Cooling Or Closed-loop Coolants

With the NSW Government saying it will require data centre investment to be matched with increased investment in renewable energy, the Climate Council was calling for mandatory standards so data centre proposals that fall short don’t go ahead. 

The state’s new guidelines are another step forward, in line with the Albanese Government’s commitment to legislate national standards –  despite resistance from Queensland and the Northern Territory, the Climate Council stated.

On July 15 2026 the Prime Minister's office stated in a press release:

''The Albanese Labor Government will introduce a world-leading artificial intelligence framework to ensure Australia can capture the opportunity, share the benefits and keep Australians safe.

We will do that the Australian way – without undercutting conditions, dividing communities or damaging our environment.

The Government will introduce a set of Australian Standards for AI, building on the Data Centre Expectations, with our values as the benchmark to ensure AI works in Australia’s interests.

The new standards will set out clear rules for large data centres— including a legal obligation to underwrite their own new power supply, pay their full share of connection costs so energy bills are not impacted, reduce power when needed to strengthen the grid, and be as water efficient as possible. 

The Federal Government will also work with State and Territories to ensure large data centres are built in the most appropriate locations, and with input from local communities.

Effective today, the Office of AI will be established within the Department of Prime Minister and Cabinet to accelerate implementation of the Australian Standards on a national level.

The Government’s approach will be considered by National Cabinet in August, with standards expected to be legislated early next year.

The implementation of these standards will deliver a simple, consistent regulatory framework for large data centres and AI training and be the first to be legislated by a government worldwide.

The Government’s approach will help further grow Australia’s economy, strengthen our sovereignty, secure benefits consistent with our national interests, and lift our standard of living.

The AI Standards will deliver greater clarity, speed up approvals and streamline the process for verifying compliance with energy, water, safety and other requirements.

The Government will also ensure the strongest possible protection for Australian artists and media.

Our approach will ensure Australian writers, artists and journalists retain ownership over their work, meaning no company should use Australian creative works to train AI without the artist’s control.

The Government will also outline its whole-of-government AI consumer safety priorities in coming weeks, building on the recent establishment of the AI Safety Institute.

The Government has every confidence that Australia can seize this moment of technological advancement and make it our own, while ensuring AI stands for Australia’s interests.''

The NSW Government's and Commonwealth standards are expected to require data centres to supply their own additional renewable power, no matter where they are built around Australia. 

Climate Council Senior Advisor Ben McLeod said:

“Australians are rightly asking: Where is the power for the data centre boom going to come from? Guidelines like these set us on the path to making sure the answer won’t push up household bills, or climate pollution. The NSW Government should be decisive in shielding its citizens and make these expectations mandatory.

“All states and territories should get on board with similar rules under the proposed national guidelines. Governments must set the bar higher, and require data centres to be powered by new wind, solar and storage, otherwise Australians will pay the price of higher power bills and more climate pollution.”

Neither the 'where possible use of recycled water' in NSW, nor the 'be as water efficient as possible' statement from the Albanese Government have allayed concerns water usage by data centres will not impact on water and electricity availability and prices. 

The inclusion of the 'extent of this increase is uncertain' statement in the policy framework, when each project would be able to determine the scale of water use required for it to operate successfully prior to being built, also perpetuates concerns over increased unsustainable water use.

Data centres must be kept cool as the thousands of packed-together servers generate intense heat and without proper thermal management, this heat causes hardware damage, permanent system crashes, data loss, and severe fire hazards. Keeping equipment cool ensures continuous, reliable operation.

Data centre cooling relies on closed-loop liquid systems or open evaporative water cycles.

Most NSW data centres, clustered in tech hubs like Macquarie Park, Artarmon, and industrial western areas like Eastern Creek, are not directly next to dedicated recycled water mains. While Sydney Water prioritises recycled water, building dedicated pipelines to distant treatment plants is difficult. For instance, a massive 612MW Eastern Creek project dropped its recycled water cooling plan because it could not secure a pipeline permit.

S7 is NEXTDC's 612MW campus at Eastern Creek in Western Sydney, developed with OpenAI under a December 2025 memorandum of understanding as part of the OpenAI for Countries program, with the first phase due in the second half of 2027.

NEXTDC switched the campus's cooling from recycled water to a waterless method after it could not secure planning permission for the pipeline needed to carry treated sewage to the site, a decision reported by Reuters on 23 July 2026.

The waterless method circulates liquid coolant around the chips and rejects the heat with fans, which data centre analysts say uses no water but more energy than the evaporative cooling recycled water would have supplied.

Since late 2025 NSW has required data centre applicants to disclose water use and meet a fixed power usage effectiveness (PUE) cap of 1.3, at the efficient end of global averages; S7 is one of six projects faced with meeting the rule, and NEXTDC has not disclosed a target PUE for it.

NEXTDC says it still favours recycled water where the infrastructure exists, and Sydney Water and coNEXA remain possible suppliers if a pipeline is approved, while Transgrid says Sydney's network is near its connection limit.

Closed Loop Coolant Systems use: Replacement of products

In a 'Closed Loop System' dielectric fluids, mineral oils, or water-glycol mixtures move across server cold plates or immersion baths, absorbing heat in a sealed circuit without direct loss. Data centre coolants rely on specific chemical and thermal properties depending on whether they are used in closed-loop water systems (like cold plates) or direct immersion baths. 

The primary fluid families are water-glycol mixtures, hydrocarbon/mineral oils, and engineered fluorochemicals, each chosen for distinct heat transfer, electrical, and safety traits.

Coolants like water, glycol, or synthetic fluids cycle continuously to absorb server heat, undergoing on-site filtration, heat exchange, or chemical treatment before ultimate disposal or repurposing via municipal recycling channels.

MassedCompute, which works to meet demand for GPU (Graphics Processing Unit) - a specialised electronic circuit designed to process data in parallel [While a standard CPU handles complex tasks one after another, a GPU uses thousands of smaller cores to run many simple calculations at the exact same time] - states Coolant replacement frequency in a data centre liquid cooling system depends on several factors, including the type of cooling architecture, the coolant chemistry, system design, and operating conditions.

Those that use fluorochemicals need replacement every 2-4 years. Their table for replacements provides:

General Replacement Intervals by System Type

Cooling System Type                                   Typical Replacement Interval Coolant Examples

Direct-to-Chip Cold Plate (Single-Phase)    Every 1 to 3 years                  Deionized water, glycol mixtures

Rear Door Heat Exchanger                            Every 2 to 4 years                  Water-based coolants

Immersion Cooling (Single-Phase)                    Every 3 to 5 years                  Mineral oil, synthetic fluids

Immersion Cooling (Two-Phase)                    Every 2 to 4 years                  Dielectric fluorocarbons

Facility Chilled Water Loops                            Every 1 to 2 years                  Treated water, glycol blends

Dielectric fluorocarbons are chemical compounds composed of carbon and fluorine that act as highly effective electrical insulators while offering extreme chemical and thermal stability. 

In the June 2026 study 'Methods for the recycling of fluoropolymers: A review' it is stated:

''Fluoropolymers (FP) are speciality polymers that have permeated into a variety of industries and uses due to their desirable properties such as high thermal stability and high chemical resistance. However, with the demand for their use ever increasing, the recycling of FP has become an area of research focus with many papers reporting recycling methodologies which limit the release of per- and polyfluoroalkyl substances (PFAS) into the environment.''

''Currently, incineration is reported to be a potential option for the complete indiscriminate degradation of FP waste and remains the most technologically ready method. Meanwhile, other methods such as mineralisation have reported the degradation of FP into high value products such as CaF2 which has the potential to bring fluorine chemistry full circle.''

The European FluoroCarbons Technical Committee, which states its main objectives are to provide up to date information about applications, safety, health and environmental effects for HFCs HFOs HCFOs and the relevant European and international legislation, says:

''Dielectric fluorocarbons can be both reused and recycled, though strict environmental regulations govern their handling due to global warming and PFAS concerns. Reusing involves filtering and drying recovered fluids for direct application, while recycling and chemical reclamation strip out impurities to restore them to original factory standards.''

''In regions with extreme weather conditions (hot climate, water scarcity), weather fluctuations or where seismic events are regular occurrences, the immersion cooling is the solution of choice for data centers as traditional air cooling cannot maintain performance and reliability.

The composition of the dielectric liquid depends on the cooling technology (single-phase, two-phase or direct-to-chip cooling). Single-phase and two-phase technologies use dielectric liquids which are based on fluorocarbons (HFOs/ HCFOs) blended with other technical fluids. Direct-to-chip cooling is not an immersion cooling per se (even though it is promoted as such) and it can use non-dielectric fluids (e.g. glycols) because the coolant never comes in contact with the component. However, the use of glycols poses major risks in case of leaks and direct contact with the system components, thus dielectric fluids are sometimes used with this technology.''

In a 16 July 2026 article 'What AI data centres really mean for Australia's water supply' by Dr M. Reza Hosseini, University of Melbourne, he points out that 'Farming alone accounts for roughly two-thirds of the water Australia uses each year'.

Under past state and federal governments, rural irrigators water extraction licences have seen water for these prioritised before communities and even river systems themselves, leading to residents of Pittwater, in an initiative led by the Aboriginal Support Group Manly Warringah Pittwater, running water water to them for drinking and for health reasons from late 2018-2019, and campaign for change from 2019-2020 and onwards.

Residents are wondering what guarantees there will be in licences granted to data centres that don't prioritise their profits before people as well.  

Regarding data centres, he states, vis-à-vis Sydney Water:

''...has fielded applications from data centre developers wanting connections of up to 40 million litres a day for a single facility. That's roughly 16 Olympic swimming pools, every day.

But that's a worst-case number. It’s the maximum a connection could supply, not what any centre actually uses today.

Developers often apply for more than they end up building or operating; utilities call this ‘phantom demand’. Even so, it explains why water companies along Australia's east coast are paying close attention.

But if we pull back to look at the national picture, the story shifts.

Industry-commissioned analysis puts direct on-site water use by Australia's data centres, mostly for cooling, at about 5.5 gigalitres (or 5.5 billion litres) a year.

....In Sydney, data centres currently account for about 0.7 per cent of local water supply; in Melbourne, about 0.2 per cent.

Industry forecasts suggest that could rise to about 1.9 per cent in Sydney and 0.9 per cent in Melbourne by 2030. Nationally, direct demand could more than triple from 5.5 gigalitres a year to around 17.

Those are forecasts, not guarantees – and they're contested.

The industry's own modelling can make the numbers look modest. The utilities, with connection applications piling up, see something starker.''

''Sydney Water has told a New South Wales parliamentary inquiry into data centres that if proposed facilities go ahead with water-intensive cooling, cumulative demand could hit 250 megalitres – that’s 250 million litres – a day by 2035.

That's a high-growth scenario, but it's the one utility companies must plan for.

The utilities are upfront that these scenarios are built on the number of connection applications, not confirmed demand that translates into actual consumption.

But what worries them is the shape of it: large customers drawing water continuously in growth corridors already stressed by drought.''

A credible proposal should have to answer five questions before it gets approved:

  1. Where is the water coming from? Drinking supply, recycled water or something else because the source matters as much as the volume.
  2. What happens in a drought? When restrictions hit households, what does the facility do?
  3. What's the peak daily demand? Annual averages hide the days that actually stress the network.
  4. Who pays for the upgrades? New pipes and connections cost money. Is it the developer or everyone else's water bills?
  5. Will the numbers be public? Water use, energy use and above all how much drinking water is being consumed

E-Waste Generated

Data centres generate massive electronic waste (e-waste) as high-density servers, GPUs, and storage drives are replaced every 3 to 5 years. Accelerated upgrades driven by generative AI push this fast-growing waste stream upward, risking millions of metric tonnes of toxic heavy metals and hardware debris globally by 2030.

Human-I-T states:

'Traditional recycling can’t keep pace with data centre e-waste — only 22.3% of global e-waste is properly collected and recycled, and recycling itself perpetuates the production cycle by turning old equipment into new products destined for eventual disposal. Data centre operators should prioritise refurbishment and reuse over recycling to reduce costs, protect the environment, and move toward a genuine circular economy. Contact a certified ITAD provider like Human-I-T that prioritises giving equipment a second life.'

Upper House Inquiry Into Data Centres in NSW

AI companies look to the ocean as a place to put more data centers

The artificial intelligence boom is driving unprecedented demand for data centers, raising concerns about their growing energy consumption, water use and carbon footprint. These challenges are making companies look beyond traditional land-based data centers.

Some developers are now exploring the ocean as a new location for AI infrastructure in the hopes that underwater data centers could improve energy use and cooling efficiency while using less fresh water and land area than onshore buildings.

My research focuses on the societal, organizational and environmental implications of emerging technologies, particularly artificial intelligence and the digital infrastructure – including data centers – that supports its development and deployment. I see underwater data centers as a promising new approach for supporting the growth of AI.

But moving servers into the ocean does not make other underlying environmental challenges such as energy consumption and carbon emissions disappear. And it creates new concerns about harm to the marine environment, as well as questions about how these data centers can be regulated – and how companies can maintain and expand them if needed. Whether underwater data centers can become sustainable alternatives to traditional data centers depends on solving these economic, technical and environmental problems.

The rise of ocean-based AI infrastructure

In 2015, Microsoft launched a research project to explore the feasibility, benefits and challenges of underwater data centers. Part of that effort included setting up a waterproof data center on the seafloor near Scotland’s Orkney Islands in 2018. It contained 864 servers and was connected to shore by an underwater cable.

After two years, Microsoft reported that the servers in the underwater data center failed at about one-eighth the rate of servers in comparable land-based data centers. The company is still studying the possible reasons but hypothesizes that in a sealed underwater environment the equipment is less exposed to oxygen, humidity and temperature fluctuations – as well as less jostling from people working to replace broken components.

However, Microsoft ended the project in 2024 and chose not to build more underwater data centers. The company didn’t say why, but others’ analyses suggest the reasons could include regulatory concerns, including the need for environmental permits, as well as a desire for faster upgrades and replacements for the computer equipment inside.

Instead the company has focused on land-based data centers, which can be larger and easier to expand, and also easier to access to repair or replace equipment.

Others have moved ahead, though. China built what may be the world’s first wind-powered underwater data center in Shanghai. The facility launched in June 2025 and began full commercial operations in May 2026.

The US$226 million project uses seawater as a coolant rather than have to refrigerate fresh water, reducing the electricity required to cool the computers. It uses at least 30% less electricity than traditional data centers, and offshore wind turbines reduce reliance on fossil fuels and cut the data center’s carbon emissions.

Japan is testing a different approach: Data centers housed in containers on floating platforms at sea can use seawater for cooling, have unobstructed conditions for solar panels and wind turbines, and reduce demand for land. In 2025, a data center in shipping containers opened on a floating platform near Yokohama. Its power comes from solar panels installed on the same floating platform, with batteries providing energy storage. The test will continue through March 2027.

Singapore is also moving toward commercial-scale floating data centers. In 2026, infrastructure company Keppel began building a four-story floating data center, scheduled to open in 2028. The project will use seawater for cooling, reducing reliance on treated water and improving cooling efficiency. And the fact that it floats means it won’t take up any of Singapore’s limited land availability.

In 2025, Ulsan, South Korea, began planning an underwater data center that could house more than 100,000 servers and use 30% less power than land-based centers by using seawater for cooling.

In Maine, DeepGreen Western Passage has proposed a submersible AI data center in the Bay of Fundy, powered by tidal turbines designed to harness the area’s strong tidal currents.

Land-based data centers could also take advantage of seawater cooling. In Portugal, the SIN01 AI data center in Sines uses seawater from the Atlantic to cool its servers before returning it to the ocean.

The promise of ocean-based data centers

These various approaches offer ways to reduce demand for grid-supplied electricity for powering data centers’ computers and cooling equipment, as well as using less fresh water.

The distance from people’s homes could also be an advantage for data centers in or on the ocean. A Gallup poll in March 2026 found that 70% of Americans oppose building AI data centers in their communities. However, more than half of the world’s population lives within 120 miles of a coast. Underwater could be another way to keep data centers physically close to users for speedy service.

Maintenance, though, is a major challenge. If a computer fails underwater, it cannot be repaired or replaced on site. The entire sealed data center module may need to be brought to the surface, even if just one computer needs work.

Can the ocean sustain AI?

The main environmental concern about ocean-based data centers involves the seawater used for cooling. Discharging warm or hot water can potentially affect oxygen levels, pH and marine life in the surrounding waters.

That heat is already apparent at the few seaborne data centers now operating. HiCloud, the engineering contractor for China’s Hainan underwater data center, has reported a temperature increase of less than 1 degree Celsius (1.8 degrees Fahrenheit) in the seawater near the facility. SIN01 in Sines, Portugal, also returns seawater about 1 C warmer.

Many marine species depend on stable water temperatures for breeding, feeding and migration, raising concerns that heat released by multiple underwater data centers could create localized thermal pollution and alter marine ecosystems. And the ocean is already under pressure. UNESCO, the United Nations agency for international cooperation, including in conservation, estimates that about 60% of marine ecosystems are already degraded or used unsustainably.

The ocean is already warming along with the atmosphere, without additional waste heat from data centers. That additional heat is already threatening coral reef and mangrove ecosystems, seagrasses and other aspects of the marine food web. As that warming continues, ocean waters will be less useful for cooling electronic equipment in some regions.

Underwater data centers could help AI grow while easing some of the pressure on land, energy and water. But the real test is whether the ocean can become AI’s next computing frontier without becoming its next environmental problem.The Conversation

Additional H5 positive birds confirmed in Narooma and Merimbula

Announced: Thursday 20 August 2026

H5 avian influenza (bird flu) has been confirmed in seven birds in Narooma and Merimbula, across six different bird flu events on the NSW South Coast.

Given the spread of bird flu across Australia, NSW is now moving to the nationally consistent reporting system of events rather than individual cases. An event is a single investigation that may involve one or more birds. It considers factors such as location, timing, species and other investigation findings, the state government has said

To date, eleven H5 bird flu events have been reported in NSW, including eight on the Far South Coast.

Bird flu events so far in NSW are as follows:

  • Event one: Giant Petrel near Hawks Nest
  • Event two: Giant Petrel near Hawks Nest
  • Event three: Greater Crested Tern near Narooma
  • Event four: Greater Crested Tern near Wentworth
  • Event five: Greater Crested Tern near Eden

New events announced today:

  • Event six: Greater Crested Terns near Narooma
  • Event seven: Greater Crested Terns near Narooma
  • Event eight: Giant Petrel near Narooma
  • Event nine: Two Greater Crested Terns near Merimbula
  • Event ten: Greater Crested Terns near Merimbula
  • Event eleven: Greater Crested Terns near Merimbula

The NSW Government is progressing plans to vaccinate priority captive native species as part of efforts to protect vulnerable wildlife populations from H5 bird flu.

Species identified as priorities for potential vaccination include little penguins and regent honeyeaters.  

Decisions on vaccinating other species will be made on a case-by-case basis, guided by the latest science and evidence, and considering factors such as disease risk, conservation significance and the practicalities of vaccine delivery.

While vaccination is an important tool, it is not a standalone solution and forms just one part of the broader response to H5 bird flu.

Since June, a national surveillance program has strengthened Australia's ability to detect H5 bird flu early and respond quickly, with the latest detection triggering enhanced surveillance in the surrounding area, including monitoring by ground crews, drones and on waterways.

Public reporting is a critical part of the response, with calls to the Emergency Animal Disease Hotline helping to support detection efforts.

Bird flu has not been detected in commercial poultry flocks or captive birds anywhere in Australia and the risk to human health remains low.

If you encounter a suspected sick bird or marine mammal, avoid contact, record what you see and report it immediately to the Emergency Animal Disease Hotline on 1800 675 888.

Minister for the Environment Penny Sharpe said:

“These new events are very disturbing but we’re continuing to prepare for further impacts of bird flu.  

“We are undertaking surveillance and we are working closely with wildlife groups to share as much information as possible.  

“NSW is also progressing plans for vaccinations and how we could expand the program.”

Minister for Agriculture, Regional and Western NSW Tara Moriarty said:

“As H5 bird flu is detected in wild birds, our focus is on early detection, rapid response and protecting vulnerable wildlife.

“We will use every tool available, including surveillance, preparedness planning and targeted vaccination programs, to strengthen our response.

“While there have been no detections of H5 bird flu in commercial poultry flocks anywhere in Australia, producers and industry are prepared and the NSW Government continues to undertake surveillance activities.”

A major push is underway to catch and vaccinate more than 5,000 little penguins in Victoria to protect them against the virulent H5N1 bird flu.

Victorian wildlife officers will carry out vaccinations at little penguin colonies at Phillip Island and St Kilda, in what the state government says is the world’s largest program to target wild birds. One little penguin at Phillip Island has already died of bird flu.

Capturing wildlife for vaccination is difficult, particularly because they may need two or more doses of the vaccine. So, how will this unprecedented program help little penguins?

A significant threat

Little penguins (Eudyptula minor) are the world’s smallest penguin, reaching a height of about 30 centimetres and weighing around 1.5 kilograms. These charismatic birds live on the southern coast of Western Australia, South Australia, Victoria and New South Wales, as well as Tasmania and New Zealand.

Famously, they can be found on Philip Island in Victoria, where more than 700,000 people come each year to see them emerge from the ocean at sunset and waddle up the beach to their burrows in the “penguin parade”.

The colonies at Philip Island and St Kilda are home to around 40,000 penguins. Because large numbers of birds live close together and the virus is highly infectious, bird flu poses a significant threat.

Capturing wildlife to vaccinate them is difficult, particularly because the bird flu vaccination requires they be caught twice, for two doses. However, little penguins are flightless, live in colonies and return at night to the same burrow, making them easier to capture and vaccinate.

Birds affected by H5N1 may be unable to stand or fly, or may appear lethargic. They may have an unusual head or neck posture, or die suddenly in large numbers without any signs at all.

Little penguins are already under pressure from invasive predators such as cats and foxes, artificial light, roads and overfishing. Climate change is also taking a toll, with warming oceans reducing fish numbers. A popular tourist attraction in Bicheno, Tasmania, recently had to temporarily close due to adults failing to return to shore and abandoning chicks. Ecologists believed it was linked to a sudden rise in sea temperature.

Other birds also being vaccinated

While the scale of Victoria’s vaccination program of wild birds is unprecedented, New Zealand – the land of birds – is also vaccinating around 300 captive (or flightless) individuals from five species. These include the critically endangered kākāpō (Strigops habroptilus), and endangered South Island takahē (Porphyrio hochstetteri).

Endangered captive birds in Australian zoos are being vaccinated too, including the regent honeyeater (Anthochaera phrygia), orange-bellied parrot (Neophema chrysogaster) and Western Australia’s black cockatoos.

The federal government recently authorised the use of H5N1 vaccines for priority native bird species. The inactivated viral vaccine (made of dead virus particles) had not been tested on any native birds, much less little penguins, until recently.

Why two doses are needed

Just like many of the vaccines we humans receive, this H5N1 vaccine requires a booster shot.

After the initial vaccination, the vaccinated animal’s immune system can detect foreign viral particles and develop antibodies. The first vaccine shot also produces specialised cells called memory B cells, which remember the protein makeup of the virus when they meet it again.

A second or booster vaccine is often required as part of a vaccination regime, typically after several weeks. This leads to a rapid increase in the number of antibody molecules in the blood because the memory B cells recognise the virus and trigger a wave of antibody production.

Having higher levels of antibodies in the blood increases the chances of them locating a virus in the blood stream, ultimately stopping the virus infecting the penguin.

Vaccines essential to response

Vaccines are not guaranteed to prevent an infection every time, and we cannot vaccinate all the penguins. But they are an important tools we can use to reduce the impact of bird flu on precious wildlife, and protect other animals.

The bird flu virus will continue to evolve and adapt to outsmart the host immune systems, much like COVID. Climate change will put even more stress on wildlife and induce virus adaption. Over time, new vaccines will need to be developed for new virus strains.

For now, bird flu is here and vaccines are an essential part of the fight.

Please not approach or touch birds that are unwell or dead. Report to the Emergency Animal Disease Hotline (1800 675 888).The Conversation

From the coasts to the plains, bird flu could threaten not just birds – but their homes

Penny Olsen, Australian National University

Yesterday, I woke to a cold, damp Canberra morning – and silence. The trees around my home were empty of feathered silhouettes. Even the usual bright-eyed, warble-voiced magpies were absent.

The next morning, they were back. I don’t know why they went AWOL. But their absence felt like a taste of what might come as the lethal H5N1 strain of bird flu spreads in Australia, affecting both birds and mammals.

Conservationists once asked: what is a bird without a tree to nest in?

This year, we may well wonder the grim inverse – what is a tree without a bird to nest in it? I can tell you. A tree without a bird is a miserable thing – and in a broader ecological sense, a tree without a bird could be in trouble.

In Australia, birds act in many roles that mammals or insects might fill elsewhere, from pollinating flowers to spreading seeds to keeping trees free of sap-sucking insects.

Bird flu doesn’t just threaten birds and mammals – it could well affect entire ecosystems.

Why birds matter so much

Australia’s birds play vital roles in most ecosystems.

As honeyeaters squabble in the canopy, mound-builders such as orange-footed scrubfowls and Australian brush-turkeys turn over vast volumes of soil and leaf litter on the forest floor, as they look for bugs or make their giant mounds.

Their digging loosens and aerates the soil, giving seeds a better chance of germinating and encouraging leaf litter to break down.

In more open woodlands and shrublands, this work is done by birds such as malleefowl, quail-thrushes and babblers.

In Australia’s wetlands, plant-eating waterbirds such as black swans and whistling ducks disperse seeds and help balance plant growth, while insect eaters such as musk ducks do the same for aquatic invertebrates. As foraging herons and pink-eared ducks stir up mud at the bottom to flush out insects, they boost oxygen levels and circulate nutrients.

As seabirds and shorebirds move between coral reefs, mudflats, islands and oceans, they deposit nutrients. Guano and other organic matter from raucous seabird colonies supply nitrogen and phosphorus for a host of species – not least fish hatchlings.

My favourite group are the falcons. These swift predators cull sick and weak prey, keeping the species fitter and helping keep the lid on pest species such as starlings, rodents and locusts.

What will happen if bird numbers plummet?

Bird flu is likely to hit some bird and mammal species very hard, but leave many others much less affected, if at all. Authorities estimate about 30% of Australian bird species are at high to extreme risk. Those at high risk face a “severe reduction” in population size, while the five species at extreme risk are potentially unable to survive.

Overseas, the virus killed millions of black-headed gulls, who live in big colonies. In the United States, a population of coastal peregrine falcons fell by more than half after the virus arrived. Waterbirds have been hard hit overseas.

The virus only arrived in Australia in June. To date, the main casualties on the mainland have been petrels and crested terns. It’s too early to predict what this might mean for Australian ecosystems.

If the virus led to insect-eating bird populations falling sharply, it could result in large trees dying. This is because eucalypts – particularly those already under stress – can gradually wither and die if birds don’t eat sap-sucking psyllids and leaf-eating weevils.

In Queensland’s tropical rainforests, cassowaries, pigeons and doves eat the fruit of trees and spread them in their fertilising dung. If these species were hard hit, the trees would be less widespread and fewer seeds would germinate.

In dry central Australia, emus, pigeons, parrots and finches play similar roles in spreading the seeds of grasses and shrubs. If their populations plummet, some plant species would gradually disappear from some areas and their genetic diversity would fall.

Uniquely in the world, a great many of Australia’s trees and shrubs have co-evolved with honeyeaters. Species such as the hummingbird-like eastern spinebill drink the nectar and act as pollinators.

If the numbers of sugar-seeking birds such as honeyeaters and lorikeets drop sharply, it would mean less cross-pollination. The plants are then forced to rely on pollination by wind or less mobile mammals and insects over much shorter distances, which results in inbreeding and a drastic drop in fruit and seed production.

It’s often claimed scavengers help stop the spread of disease. Unfortunately, bird flu can infect scavengers and predators.

What future for the land of birds?

Around 850 species of birds are found in Australia – and close to half are found nowhere else.

Birds play vital roles, from waste disposers to seed dispersers to pollinators and pruners. Birds control pests, produce fertiliser and engineer ecosystems through their digging. They can be predators and prey. They can be long-distant migrants, linking us to the rest of the world, or ultra local.

This is why I and the many others who love birds are so grieved by the threat posed by bird flu – even though we do not yet know which species will be worst affected.

After a morning with no birds, I’m buoyed by the sight of close to sixty galahs on the lawns of the National Library. I watch as they deftly extract and eat the corms of onion grass, an invasive weed.

I take some hope in the fact Australian birds are resilient, having carved out niches on the driest inhabited continent for many millions of years. It was here the world’s songbirds and parrots evolved before spreading across the globe.

Bird flu will do much damage. But we can help them recover by tackling other threats. There will always be birds. There must always be birds.The Conversation

Hundreds of dead birds are now being reported as the lethal H5N1 strain of bird flu begins to spread across Australia. Government reports show the virus is circulating in resident birds.

It was a long time coming. The current outbreak emerged in 2020. By late 2021, it was spreading widely, leaving a widespread trail of devastation among wildlife species across Europe and the Americas. Even as Antarctic birds and mammals began suffering over 2024 and 2025, Australia – and New Zealand – remained free of this viral strain. Until now.

It’s easy to picture bird flu as an unstoppable wave set to decimate Australian birds and mammals. But that’s not set in stone. Overseas evidence shows the first wave tends to be by far the worst. And deaths from the first wave can vary greatly, with many populations and individuals surviving.

That’s good news for some – but it won’t save vulnerable species who may lose a large proportion of their global population. For them, recovery is likely to take decades – if at all.

The first wave is devastating

In 1996, a new highly pathogenic strain of bird flu emerged in poultry in China. Periodic outbreaks forced mass poultry culls and sporadic die-offs in wild birds.

In 2020, a new variant – formally known as H5N1 clade 2.3.4.4b – was detected. Soon, it was sweeping through Europe and North America.

It was immediately clear the virus had become more devastating.

Less dangerous strains of bird flu (termed low pathogenic avian influenza viruses) tend to replicate in a bird’s gastrointestinal tract, while earlier high pathogenic strains tended to replicate in the respiratory tract.

But this new strain could infect both. Not only that, it was able to infect the central nervous system, leading to neurological disease and death.

The strain has evolved many new variants since 2021. These can now infect over 500 wild bird species, of which over 50% had not had infections previously recorded.

Then came reports of fatal infections in mammals, from scavengers such as foxes to herbivores such as deer and marine mammals such as sea lions. Many had never had bird flu before. The virus was even able to infect livestock such as cattle. Human infections are thankfully rare, with no reports of the virus spreading between people so far.

Across western Europe and North America, deaths of breeding-age adult birds were as high as 25–76% in the worst-hit species. Many populations had near-complete breeding failures.

In 2023, it hit South America. Some bird species lost up to 50% of their global population, while marine mammals suffered their first mass deaths. In Argentina, 17,000 elephant seals died in a single colony.

What happened next?

While mass deaths of wildlife made global headlines, little media coverage has focused on what happened next.

Mass deaths don’t seem to strike the same populations year after year, even though the virus is still circulating.

Adult sandwich terns in western Europe died in droves in 2022. But in 2023, mortality rates in adults fell by 96%. That year’s chicks were hit hard, but those hatching in 2024 did far better.

Why? Older, more vulnerable birds all died off in the first wave, and surviving terns gained some immune resistance. Younger birds previously shut out from breeding took advantage of the situation, while chicks benefited from reduced competition for food.

Overall, sandwich tern numbers only fell modestly. Even so, the species is projected to take almost 20 years to recover to its pre-outbreak level.

Not all populations or individuals were affected equally – even in the first wave. Atlantic seabirds breeding in large, dense colonies were hit hard. Gannets, terns and skuas all saw mass deaths. But neighbouring petrels, puffins and shearwaters nesting in burrows had far fewer deaths.

This may give some protection to Australia’s burrowing little penguins. Authorities are also moving to vaccinate thousands of these penguins.

For many species, bird flu is made worse by other threats. In 2024, Adéle penguins in Antarctica had to battle both bird flu and deadly avian cholera, leading to many losses. Similarly, bird flu hit African penguins already in trouble from the collapse of sardine fisheries.

We can’t directly extrapolate from overseas experience. Many Australian birds and mammals are unique. Some, such as black swans, lack crucial immune defences against influenza.

The death toll is not set

Official estimates suggest about 20% of bird and 10% of mammal populations in Australia are at high to extreme risk of population impacts from this strain.

But catastrophic destruction is not guaranteed. Whether a species is hit hard or barely touched will depend on three things: level of exposure to the virus, how well it can resist infection and how well it can cope with being infected.

Before this strain arrived, experts evaluated the risk for all Australian bird and mammal species, developed action plans for important sites and expanded surveillance and diagnostic systems to monitor outbreaks and viral evolution. These measures are globally recognised as the most important tools.

Australia is now following New Zealand in vaccinating captive and closely-managed populations.

Worldwide, no species has suffered 100% losses. That means some individuals likely survived the infection. Generally, animals can cope better with infection if they’re well fed, in a good habitat and aren’t exposed to pollution or stress.

The biggest lever we can pull is tackling these other pressures, from habitat loss and plastic pollution to invasive species.

We have a chance to try relieving these pressures on wildlife to give them more of a fighting chance – but the window is shrinking.The Conversation

National Parks protect Southern Right Whales with new ‘stay away’ distance of up to 500 metres

The NSW National Parks and Wildlife Service (NPWS) has issued a Special Order for all vessels to stay at least 500 metres, and swimmers 100m, away from all Southern Right Whales in NSW waters.

The Order will be in place until 30 November 2026, when the breeding and calving season ends in NSW.

Southern Right Whales attract a lot of attention as they stay close to beaches and move slowly on the surface. Although incredibly rare, they are easily spotted when they visit.

The Order comes after a mother and calf were recently spotted off Sydney, with curious boaters and locals venturing close to the pair.

The NPWS citizen science project ‘Right Whale ID’ has tracked individual whales through their unique white facial callosities for the past 6 years. Research has found that even a single swimmer approaching too enthusiastically can trigger a significant negative behavioural response in the whale.

Identifying one of the handful or so Southern Right Whales off the NSW Coast each whale season, as opposed to one of the 40,000 humpback whales, is fairly simple.

Any slow-moving, 14-16 metre long whale which is 500m or less off an ocean beach could be a Southern Right Whale.

Identifying features include:

  • a distinctive V-shaped blow when they exhale
  • large broad body size, absence of a dorsal fin
  • white markings (skin growths) on their faces and heads known as ‘callosities’
  • the tail/fluke is geometrically angular and usually black on both top and bottom sides.

Southern Right Whales have a distinctive V-shaped blow when they exhale

Unlike Humpbacks, mother and calf Southern Right Whales spend more than 90 per cent of their time in waters shallower than 20m, and often less than 500m from shore. While nursing , they move very slowly, engaging in a still, energy-saving behaviour called ‘logging’, which is floating at the surface for long periods.

These behaviours make them highly susceptible to disturbance from overly curious people swimming, paddling or boating too close for the mum’s comfort.

Disturbances can cost the animals precious energy budget as their responses often include significant increases in swim distances as they try to evade them. The disturbance effect is seen in tracking data over subsequent days.

NPWS asks people to comply with the keep-away distances to help protect these mammals.

Members of the public, partner organisations and NPWS staff will collect witness accounts when people venture too close to Southern Right Whales and proceed with investigations where warranted. Non-compliance could result in fines or court appearances.

If anyone spots a Southern Right Whale, please report to NPWS or ORRCA hotlines on 1300 072 757 (13000 PARKS) or (02) 9415 3333 immediately, which allows the Right Whale ID team to get on site as soon as possible.

NSW National Parks and Wildlife Service Marine Wildlife Project Officer Andy Marshall said:

“Doing the right thing by Southern Right Whales means the southeast Australian population has a better chance of recovering.

“I would like to think that future generations will be able to see these incredible animals and be awed by them, in the same way we are today.”

Distances prescribed under the Special Protection Approach Distance Order

Vessels, aircraft, swimmers - Special Protection Approach Distance

  • For vessels including jet skis, surfboards- Stay away 500 metres
  • Operating a crewed aircraft- Stay 610m away – either above or to the side of the whale
  • When swimming including snorkelling and diving- Stay away 100 metres

Dedicated alpine weather page part of latest BOM website improvements

The Bureau of Meteorology has delivered its latest website update.

In this release navigation has improved, there’s a new dedicated alpine weather page in time for the ski season, and the weather map has more place names.

Bureau of Meteorology CEO Dr Stuart Minchin said the update was a direct response to community feedback.

“Since launch, we've had requests for more locations to be added to the weather map,” Dr Minchin said.

“Our website is there to serve all Australians. We've now added more than 100 place names, primarily in the Northern Territory and Queensland.

“We'll be adding hundreds more in the months ahead.”

The weather map will now remember users’ most recent pan and zoom position, keeping the settings the same for the next time the page is viewed.

For example, if your last visit was a maximum zoomed-in view of Mount Isa, Queensland, this is the view you'll see next time you visit the rain radar.

“Changes like these will make it easier for everyone to find what they need,” Dr Minchin said.

Other changes include the UV Index being restored to the hourly forecast and updating the presentation of flood warnings.

A new alpine weather page provides weather map layers for snow, wind and temperature, and forecasts for snow resorts, towns, and remote areas in Australia's alpine regions in one page.

The updated Alpine regions page provides weather maps and forecasts for snow resorts, towns, and remote areas in Australia's alpine regions.

Alpine regions offers information across 2 tabs:

  • Forecasts – alpine districts and locations
  • Map – 3 hourly snow, wind and temperature forecasts.

Navigating the website has become easier with changes to tabs and page layouts on a number of key pages such as Forecasts and observations, Coasts and Oceans and state, territory and district pages.

“People have told us that navigating to forecasts and observations for districts and states was hard,” Dr Minchin said.

“We’ve paid close attention to this feedback.

“Combined with last month's search improvements, this will make it easier for regional web users to find out if their district is expecting rain or sunshine.”

Updates will continue to be made to the website in response to the feedback received from the community.

Information about recent changes is available at bom.gov.au/website-help/website-updates

The ski season starts on the June long weekend and runs until October's long weekend in NSW.

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.

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.

Mountain Bike Incidents On Public Land: Survey

This survey aims to document mountain bike related incidents on public land, available at: https://www.surveymonkey.com/r/K88PSNP

Sent in by Pittwater resident Academic for future report- study. 

Report fox sightings

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?

The world’s biggest trees could hold the secret to coping with drought

Amy Bennett, University of Leeds

Rising more than 70 metres above the rainforest canopy, a giant skyscraper of a tropical tree can seem almost invincible. Some have survived centuries of storms, droughts and competition.

Large trees face a formidable engineering challenge, lifting water tens of metres from the soil to leaves high above the forest floor. A challenge which intensifies during drought.

But are giant trees uniquely vulnerable to drought or could they help forests remain resilient as temperatures rise?

Research in this area over the last decade shows there is no single way tropical forests respond to drought. In some forests large trees die disproportionately; in others they appear surprisingly resilient.

In 2015, my colleagues and I analysed how drought affected forests around the world. We found that, during drought, larger trees were more likely to die or have stunted growth than smaller trees.

It seemed logical to us. Larger trees must transport water over greater vertical distances. They are more exposed to sunlight and atmospheric demands. Their crowns sit above the canopy where temperatures are higher and conditions are harsher.

Hydraulic theory pointed in the same direction. Trees move water from roots to leaves through a continuous column under tension, like drinking through a straw. During severe drought that column can break, causing hydraulic failure and potentially tree death. In 2012, researchers showed that many tree species operate very close to the limits of their water transport systems during drought.

So, large trees look to be particularly vulnerable.

Drought in the Amazon during the warm phase of the very strong El Niño event in 2015-16 appeared to confirm the pattern. Working with colleagues across tropical South America, we measured more than half a million trees to try to understand forest responses to drought. The region’s forest has acted as a net carbon sink, by absorbing more carbon than it emits. But the sink effectively disappeared and more trees of all sizes died, with the increase greatest for the largest trees.

Interestingly, the forests most affected were not necessarily those in the wettest environments. Instead, the strongest consequences occurred in forests already growing in relatively dry conditions, particularly around the edges of the Amazon.

These forests contain tree species that routinely cope with seasonal drought. Yet they still proved highly vulnerable to extreme heat and water stress. Adaptation to regular drought doesn’t necessarily protect forests from unusually intense heat and water stress.

Trees with less dense wood were also more vulnerable, a result that matched expectations from hydraulic theory. A 2023 study demonstrated that hydraulic traits can directly predict drought mortality risk in Amazon forests.

Together these findings appeared to strengthen the case that drought vulnerability is tightly linked to the hydraulic challenges faced by large trees.

But the impacts of drought in African tropical forests told a different story during the same El Niño.

Rather than large trees suffering the most, growth declines were strongest among smaller trees. The largest trees appeared comparatively buffered from drought stress.

The contrasting responses demonstrate that not all trees or forests respond to drought in the same way. There may not be a universal link between drought and tree mortality. The major cause of death may differ among forests, in some hydraulic failure may dominate, while in others competition, carbon limitation or disturbance may be more important.

We’re no longer asking whether large trees are vulnerable, but under what conditions do they become vulnerable?

A recent study published in Nature across a rainfall gradient in Puerto Rico adds another layer. Researchers found that drought-resistance traits varied, even within species, with trees in drier forests having greater resistance to hydraulic failure.

Forest resilience may depend not only on which species are present, but also on the capacity of species to adapt to local drought conditions.

Dipterocarps are the giants of the forest. Trees in this family grow to massive sizes, have high wood density and therefore store large amounts of carbon. They often emerge high above the canopy like skyscrapers. Dipterocarps dominate many Southeast Asian forests and include some of the tallest tropical trees on Earth. Measuring them is extraordinarily difficult.

Having worked in these forests in Borneo, I know how hard these trees are to study. The terrain is steep, the trees enormous and often buttressed. Making physiological measurements throughout trees so tall is an extraordinary achievement.

A recent study found that these giant trees appear able to compensate for the hydraulic challenge of height through anatomical and physiological adjustments, maintaining hydraulic function despite their great size.

Size might not be everything

The findings suggest that, in these forests, size alone does not necessarily increase drought vulnerability.

One implication is that size itself may not drive vulnerability. Instead, size may simply be a proxy for exposure to brighter, hotter and drier canopy conditions.

In many studies, large trees are more vulnerable because they experience these harsher conditions. But if a species or individual tree can compensate physiologically, as dipterocarps on the island of Borneo appear able to, the relationship between size and vulnerability becomes more complicated.

Truly giant trees are rare. Surprisingly little is still known about them.

In most long-term forest inventory plots, the largest trees are only a handful of stems. The so-called large trees in many datasets are often much smaller than the skyscraper trees found in places such as Borneo.

Are dipterocarps exceptional? Or have we simply under-sampled resilience among giant trees globally? At the moment, scientists don’t know.

What is becoming clearer is that there is no single rule to predict the drought responses of forests.The Conversation

We’re building a New York‑sized city every month. That’s worrying for our climate

Each of us needs of a roof over our head, classrooms to learn in and offices or space to work from.

To meet this unprecedented demand for new buildings, globally we’re constructing the equivalent of an entire New York City every month.

This provides us with vital infrastructure, but also generates an enormous amount of world-warming emissions.

So how can we build what we need, without harming our planet? Our new research provides some answers.

The need to build

Creating new buildings benefits communities, cities and countries, and eases housing pressure. That’s why Australia’s National Housing Accord is aiming to construct 1.2 million new, well-located homes between 2024 and 2029.

But this Australian effort is dwarfed by the 96,000 new and affordable homes needed worldwide every single day. Tragically, hundreds of millions of people around the world endure homelessness. One in four are living in harmful conditions.

However, construction comes with a climate cost. Each time we build, we use materials and construction processes that release large amounts of greenhouse gas emissions – known as “embodied carbon”.

To understand the scale of embodied carbon, picture a square metre of floor space. Constructing that square metre would release around half a tonne of greenhouse gas emissions. Now scale that up to building a whole New York-sized city every month!

What we studied

Our new study examined trends in office building construction in Australia. We currently have about 170 million square metres of office space across the country, and are set to build a further 100 million square metres by 2049.

To investigate what effect these buildings have on global warming, we modelled their greenhouse gas emissions. We measured both their embodied carbon and operating carbon – the emissions from everyday heating, lighting, cooling and appliances.

We found Australian office buildings are projected to release 138 million tonnes of greenhouse gas emissions between 2024 and 2049. This number is equivalent to the annual emissions of 36 coal-fired power stations. Given offices make up just 20% of all commercial buildings in Australia, this is only a fraction of our total urban emissions.

A mixed picture

Most surprisingly, operating emissions represented 85% of the total in 2024, but are set to drop to just 15% by 2049. This is because Australia is decarbonising our energy sector by shifting from fossil fuels to solar, wind and other renewables.

However, if we keep building at our current speed and scale, our annual embodied emissions will remain at similar levels. Compared to operating emissions, it’s more difficult to lower embodied carbon because many material supply chains rely on fossil fuels and carbon-intensive practices. The process of manufacturing cement, for example, is responsible for 8% of all global carbon dioxide emissions.

We also compared office building emissions in Australia with emission pathways that would limit the sector’s contribution to global warming below 1.5°C or 2.0°C. However, we found cumulative emissions from offices are over 40% above these pathways. This means office buildings will likely blow their carbon budgets within a matter of years. We found Tasmania – which runs almost entirely on renewable energy and has fewer office buildings per capita – is the only state or territory with annual emissions that sit consistently below the 1.5°C pathway.

Cutting carbon

Our study measured several ways to reduce embodied carbon in office buildings, summarised below:

We found combining these strategies could reduce total emissions by over 47 million tonnes, putting the office sector far closer to the 2.0°C emissions pathway target.

These results show the importance of “sufficiency” measures, such as refurbishing existing buildings and constructing smaller, or fewer, new buildings.

Research shows sufficiency strategies work. Consider Sydney’s Quay Quarter Tower. This tower was originally built in 1976 but, by the late 2010s, was older and less useful. Rather than demolish it, architects 3XN and BVN extended the tower to the north and upcycled two-thirds of the original structure. This increased office space while saving around 8,000 tonnes of embodied carbon.

More work ahead

Our study suggests embodied carbon will, in the next decade, overtake operating carbon as the leading source of building emissions. This is problematic because most countries don’t impose limits on embodied carbon. As a first step, Australia must regulate embodied carbon emissions as other countries – including Denmark, Finland, France, the Netherlands and Sweden – have already done.

We should also offer incentives for the construction sector to refurbish older buildings. Several councils in the United Kingdom have adopted “retrofit first” policies, where builders must at least consider options for refurbishing buildings before simply demolishing or replacing them.

Our ever-growing global population demands millions of new homes, workplaces and community spaces. But to truly tackle climate change, we must find better ways to balance society’s need for new space with a commitment to curb emissions.The Conversation

Australia’s EV sales are skyrocketing. Our charging infrastructure may soon struggle to keep up

Electric vehicles (EVs) seem to be popping up everywhere.

In the first half of 2026, sales of battery-powered EVs nearly tripled, and July’s figures suggest this trend will continue.

However, our cumulative research reveals Australia’s charging network may soon fail to keep up with the booming EV market.

Behind the boom

Over the past six months, sales of battery-powered EVs have surged to represent 23.4% of the new car market, up from 8.4% in January. And this growth is showing no signs of slowing.

Combined data from the Electric Vehicle Council and the Federal Chamber of Automotive Industries shows more than 108,000 new cars hit the road in July, of which more than a fifth were battery-powered EVs.

Major EV manufacturers Tesla and Polestar alone delivered more than four times as many new vehicles in July as they did in the same month last year. BYD, which sells EVs and hybrid cars, is now Australia’s second best-selling brand overall behind Toyota. It upped its new car sales by 70.5% year-on-year.

Until recently, Australia appeared to be a laggard in the uptake of EVs. This is despite a large and growing appetite for home electrification technology, including rooftop solar and home batteries.

This year, EVs seem to have become just as popular. In July, sales of petrol and diesel cars fell sharply as fuel prices climbed. Meanwhile, plug-in hybrid sales surged by 157%. This suggests new segments of the EV market are now opening up and attracting different types of customers.

Rapid rollout

Retailers and fuel companies are racing to meet this unprecedented demand for EVs with increasingly high-powered chargers.

Coles, in partnership with Evie Networks, is installing 200-kilowatt fast chargers at up to 30 supermarkets in Victoria and Queensland over the next two years.

Ampol has just switched on its first 400-kilowatt chargers as it aims to establish the country’s leading charging network by 2030. BP is building a 24-bay charging hub at Melbourne Airport, adding to the nearly 300 bays it has installed nationally since 2022.

The National Roads and Motorists’ Association is expanding its highway charging network, building 35 new sites in 2025 after receiving nearly A$40 million in federal funding.

Soon, EV fast chargers may be a common sight at places like your local supermarket and servo.

Where the problem lies

Governments are quick to fund new chargers, but this money often disappears after the ribbon is cut.

Chargefox, Australia’s largest charging network, owns very little of the hardware it relies on. It’s a network of networks, bundling chargers owned by other charging networks, councils, businesses and energy companies into one app. This means EV drivers may struggle to know who is responsible for a flawed or broken charger.

Having one dominant charger operator creates other issues. One study found Chargefox controls 83% of Tasmania’s public chargers and 58% of those in Western Australia. In such a concentrated market, one company’s bad month rapidly becomes a state-wide outage.

In WA, the Royal Automobile Club quietly wound up its decade-old Electric Highway project last year. It established 16 charging locations from Monkey Mia to Esperance, and was one of the first networks of its kind in Australia.

The project is now in the hands of local councils, many of which lack the resources and skills to manage such complex infrastructure. Several councils have decommissioned broken units rather than repair them. Others have pulled out chargers altogether, creating complete gaps in the network.

Not just Australia

Other countries are trying to ensure their public charger rollout keeps pace with surging EV demand.

In the United States, federal standards apply only to chargers built with federal funding. Individual states, such as California and Hawaii, require any charger connecting to the grid to meet their own technical standards.

In the United Kingdom, the government mandates that all public rapid chargers have 99% uptime. Uptime is a measure of how often a charger is available and working. But operators are required to self-report their uptime figures, which are rarely tested by government or an independent body.

The European Union has stronger enforcement, requiring charger companies to share their uptime and payment data with authorities.

However, these approaches have failed to close the gap between reported uptime and what drivers actually experience.

A landmark study of San Francisco’s public chargers found only 73% worked when tested, compared to operator claims of 95% to 98% uptime. We observed the same pattern in our recent analysis of chargers funded by the Californian government.

Despite these challenges, most mature EV markets do have some kind of national strategy for EV charging infrastructure, delivered through local means.

What we can do

We can strengthen Australia’s charging network by:

  • applying federal minimum operating standards, that currently require 98% uptime for chargers built with taxpayer dollars, to privately funded chargers

  • linking charger funding to performance rather than just installation, as the US does, so operators are incentivised to maintain reliability

  • ensuring networks in rural and remote regions are carefully planned and positioned along key highways

  • requiring charging companies and car manufacturers to disclose data, including how quickly cars charge, how often chargers fail and where, and which sites are charging hotspots to identify potential bottlenecks.

For now, Australia’s charging network is growing fast enough to meet the needs of EV owners. But that could soon change if we keep building new chargers while leaving existing ones to break down or simply disappear.The Conversation

Parasite linked to ‘mushy fish’ could be much more widespread than thought

Jessica Tout-Lyon, Charles Sturt University

If you’re a keen angler and regularly catch yellowtail kingfish (Seriola lalandi), you may have encountered instances of the fish’s flesh turning mushy and unpalatable once cooked. Some have said it’s a bit like trying to eat wet newspaper.

This can be disappointing for the angler and for the hungry guests you’ve invited to dinner. It is also a waste of food – and of the fish’s life.

It’s often hard to pinpoint which fish will turn mushy when cooked as they can look, smell and taste the same when raw, such as when served as sashimi. The issue only appears once the fish is cooked or prepared as ceviche. In other words, you need heat or a pH change for the problem to reveal itself.

The mushy flesh problem is associated with the parasite Unicapsula seriolae but it’s too soon to say it’s definitely the cause – that research hasn’t been done yet.

What we do know is that this parasite shows up in a lot of kingfish that turn mushy when cooked.

Now, our research suggests infection with Unicapsula seriolae may be more widespread than first thought.

In fact, we found even flesh that doesn’t go mushy after cooking can still be infected.

Mushy kingfish and parasite infection in NSW

I’ve been fascinated by the mushy kingfish problem for over 15 years now, following my own encounters in the waters off Sydney, the mid north coast of New South Wales, and at the dinner table.

There are reports dating back to the 1990s of people in NSW catching kingfish that later turns mushy when cooked.

But our research wanted to go beyond anecdotal evidence, so we scientifically tested for and detected this parasite in kingfish caught in NSW. For the first time, we show it is present in kingfish from NSW.

Scientists had previously only tested for and detected this parasite in kingfish caught in Queensland and Western Australia, and in aquaculture settings in Western Australia.

Our recent research involved working closely with NSW-based anglers, spearfishers and charter operators to obtain donations of kingfish tissue in 2024 and 2025.

We tested for the presence of microscopic parasites in kingfish by:

  • looking at samples under the microscope

  • doing polymerase chain reaction (PCR) testing and

  • DNA sequencing.

In the samples we tested, we found 38.9% of fish were infected with the myxosporean parasite, Unicapsula seriolae. This falls within the range of infections in wild kingfish in previous Australian reports, which put the figure at between at 29.3% and 80%.

But crucially, we also showed that a larger proportion of infected fish (71.4%) did not develop mushy flesh when cooked, or were asymptomatic.

This indicates that relying on fish turning mushy once cooked will mean most infections get missed.

This microscopic marine parasite is similar in size to the human red blood cell, making it impossible to spot with the naked eye. Only some fish will develop signs of infection in the form of black cysts that can be seen with the naked eye.

We also found the parasite in fish caught throughout the year, even though the issue of flesh turning mushy when cooked only usually shows up in fish caught in summer and spring.

This might suggest there’s a temperature link that causes this issue to become more prevalent in warmer months, but it’s too soon to say for sure.

How does this parasite affect fish health and human health?

Scientists don’t yet fully understand the impacts this parasite can have on the health of kingfish. But we do know that in aquaculture settings outside of NSW this parasite has been associated with mass-mortality events (when other pathogens are also present).

Despite this, we still do not know the exact role the parasite plays in the health and physiology of wild kingfish.

Scientists are also unsure what the consumption of raw Unicapsula seriolae-infected kingfish means for human health.

Currently, there is no evidence to suggest it causes food-borne illnesses here in Australia. In Japan, the same parasite has been linked to cases of food-borne illnesses in people who ate raw greater amberjack (Seriola dumerili) – a species closely related to the yellowtail kingfish.

We do not have any accounts of similar cases here in Australia. More research is required to investigate the impacts to human health, if there are any.

All in all, we found most infected kingfish from NSW waters do not become mushy when cooked. And we still do not exactly know why the flesh turns mushy when cooked for some infected kingfish but not others.

Further research is required to understand the significance and consequence of infection, and to develop improved rapid detection methods.

Although sample sizes were small, we are continuing our work to better understand infection.

People are more likely to ditch the car and use an e‑bike if they feel confident and safe

Jennifer L. Kent, University of Sydney

Finally, Australians are being encouraged to swap four wheels for two. Governments are investing in cycling infrastructure, and calls for e-bike subsidies are growing louder.

But our research suggests there’s a missing piece in this puzzle.

Giving people access to an e-bike is important. Building safer cycling infrastructure is fundamental. Yet neither is likely to change travel behaviour on its own. If we want people to leave their cars at home, they also need the skills, confidence and support to ride.

That was the clearest lesson from our study of 42 Western Sydney residents who took part in an eight-week supported e-bike program. The bike opened the door – but it was training, guided rides and social connection that gave people the confidence to walk through it.

Interested in cycling, but intimidated

Transport is Australia’s fastest-growing source of emissions, while car dependence places increasing financial pressure on households and contributes to congestion, inequity and poorer health outcomes.

For many policymakers, e-bikes appear to offer a promising solution. Unlike conventional bicycles, e-bikes make longer distances, hills and hot weather much easier to manage. They can replace short car trips, connect people to public transport, improve health and reduce transport costs. Around the world, governments have responded with subsidy programs designed to make e-bikes more affordable.

But there is an assumption built into many of these programs: if people have access to an e-bike, they will automatically use it.

Our research suggests that’s not always the case.

Many Australians are interested in cycling but feel intimidated by riding in traffic. Others are uncertain about route planning, road rules or cycling infrastructure. In highly car-dependent places, cycling can feel unfamiliar, risky or at odds with car-related norms. Simply providing technology and infrastructure does not overcome this.

What if we combine e-bikes with support?

The Transformers Project, delivered in Western Sydney during 2025, tested a different approach.

Participants received subsidised access to an e-bike for eight weeks. But they also took part in guided rides around their local area and practical education sessions on bike-handling, storage and maintenance. In addition, they were given opportunities to connect with other riders online and face-to-face.

The results were striking.

Participants covered over 3,000 kilometres during the trial. They used e-bikes for commuting, shopping, recreation, volunteering and social activities.

Survey results showed:

  • 75% increased cycling for transport

  • 92% reported greater riding confidence

  • 71% said travel had become more enjoyable.

But the numbers only tell part of the story.

Through in-depth interviews, participants spoke in excited detail about increased independence, improved mental wellbeing, stronger community connections, and greater confidence in engaging with their local environment.

One participant, Florence, said:

The endorphins from riding[ … ]and seeing all these different places that I had either driven past and never really looked at or noticed it was so amazing[ … ]it’s brought me so much joy.

And with each story came a key reflection: although access to the bike and safe cycling infrastructure laid the foundations for change, it was the program’s support that made participants feel confident to sustain it.

Belonging and confidence matter

Participants consistently praised separated cycleways and safer cycling infrastructure. Many were surprised to discover just how much cycling infrastructure already existed in their local area.

Yet they also pointed out something transport planners often overlook.

Travel behaviour is shaped not only by roads, paths and parking facilities, but by beliefs about what feels normal, safe and socially acceptable.

In highly car-dependent places, cycling can feel like stepping outside the norm. Participants often described feeling out of place when they first began riding. Some worried about their skills, while others worried about how family members, motorists or strangers might view them.

Mai, for example, valued the independence the e-bike offered but only felt comfortable riding in a group. Shirley said her family worried about her cycling and were not particularly supportive.

Even confident riders sometimes felt self-conscious when combining cycling with public transport. Ryan told us:

Going on public transport is intimidating with the e-bike because you feel that people[…]will have an issue with it.

These stories highlight challenges rarely captured in transport models. People are not simply making rational decisions about time and cost. They are also responding to fears and cultural assumptions about who belongs on the road.

The program helped normalise cycling. Over time, cycling became less of a risk and more of a routine.

Cycling needs to be a social practice

Countries with high cycling rates did not achieve them through infrastructure alone.

Places such as the Netherlands and Denmark broken link combine infrastructure investment with cycling education, social programs and training that begins in childhood. Cycling is supported as a social practice as much as a transport mode.

Australia’s investment in cycling infrastructure remains essential. We need safer bike lanes, secure parking and better integration with public transport. But our findings suggest governments should also view behaviour change programs as transport infrastructure. Education and mentoring are not optional extras.

The lesson from Western Sydney is simple.

Give people a bike and some may ride. Give them a bike, the skills to use it, the confidence to try and a community to support them, and many more will leave the car at home.The Conversation

Want to fully electrify your house? Don’t start with a battery

Many Australians want to go fully electric. But it’s often hard to know where to start. Solar? A home battery? Or quitting gas?

To find the best way to make the shift, we modelled three pathways for a three-bedroom house in Melbourne’s western suburbs.

These pathways show it’s important to do things in the right order. It’s best to start by lowering energy demand through better insulation and stopping draughts, and then switch from gas heating to an efficient reverse-cycle air conditioner. Home batteries should ideally be done last.

What did we do?

We used benchmark data to model a household with ducted gas heating, gas hot water and cooktop, common electric household appliances and a petrol car.

Each year this household uses 5,300 kilowatt-hours of electricity, just under 50 gigajoules of gas, and about 1,230 litres of petrol (to drive 11,100 kilometres). This costs A$2,477 for electricity, $1,494 for gas and $2,255 for petrol. Total energy costs are $6,226 a year.

We modelled replacing these with a 10-kilowatt ducted reverse-cycle air conditioner, a hot water heat pump and an induction cooktop.

We model two further options: one where the household switches to a mid-range EV with a battery of about 60kWh and another where the household keeps its petrol car.

Which pathway?

We tested three pathways to going electric. These don’t include rebates or the cost of the EV.

Pathway 1a – all electric, no battery, EV

Here, the household adds a large 11.76kW solar array, gets off gas and replaces its petrol car with an EV.

Although total electricity use rises, the grid electricity bill falls due to solar. The new electricity bill would be about $1,800. Because gas and petrol costs fall to zero, the household saves about $4,400 yearly.

Total cost: about $32,600.

Pathway 2a – all electric, medium home battery, EV

This pathway mirrors the first, but adds a 13.5kWh home battery at the end. The power bill falls to about $950. Savings would be about $5,300.

Total cost: about $48,100.

Pathway 3a – all electric, large home battery, EV

Here, the household doubles storage to 27kWh. The power bill drops to about $600. It doesn’t reach zero due to low solar over some periods and annual supply charges. Annual savings: about $5,900.

Total cost: about $56,400.

We also model three scenarios (1b, 2b and 3b) where the household keeps its petrol car.

These figures combine the prices in Victoria’s official guide with advertised price benchmarks for installed appliances as of June 2026. The hot water heat pump is costed after an upfront discount. These pathways don’t directly hold for other regions, due to factors such as climatic difference and government incentives.

Stacking rebates

Governments offer a range of rebates and subsidies for households to go electric.

Federal incentives

Pathway 1: Applying a solar rebate means the cost falls to just under $30,000.

Pathway 2: Using solar and battery rebates, the cost falls to about $41,700.

Pathway 3: After both rebates, the cost falls to $47,800.

State rebates

In Victoria, the maximum possible state support comes to just over $6,000.

This includes $1,400 for solar, $1,400 for locally made hot water, and indicative discounts of about $2,500 to replace ducted gas with a 10kW reverse cycle air conditioner, $560 to switch from gas hot water to electric and $140 for induction cooktops. These are maximums, not entitlements, and there are eligibility requirements.

If the household was eligible for all federal and Victorian rebates, the total cost would fall to about $23,900, $35,800 and $41,800 for the three pathways, respectively.

Electrify in the right order

Our modelling suggests an optimal order for going electric.

1. Reduce demand

The first step is making the house more energy efficient by sealing gaps, boosting insulation and adding shading to stop direct sun. This can make it possible to install smaller appliances.

2. Go solar

Solar is a no-brainer almost everywhere. When choosing the size, it’s best to go bigger to power a future all-electric home.

In Melbourne, a 11.76kW array would produce about 15,400kWh a year. Set hot water systems, appliances and EV chargers to run during the day to maximise use of solar. Our modelled all-electric household with an EV uses 8,500kWh a year in total, including 1,800kWh for EV charging.

3. Get off gas

First, replace expensive older gas heaters with a correctly sized reverse-cycle air conditioner. This will bring immediate savings and can also cool in summer.

Next, replace gas hot water with a quiet, efficient heat pump.

Then replace gas cooktops with induction. These can be expensive, so consider trialling a portable induction hob. Finally, abolish the meter.

4. Consider a battery

Batteries should only be installed if they are useful. The most common use is releasing stored power from solar to avoid peak evening rates.

Home batteries are more valuable once gas appliances and petrol cars have been replaced and the home is fully electric. In our model, the first battery saves about $852 a year, while doubling storage saves only another $355 a year. This is why they should be done last if possible.

How quickly does this pay off?

Unlike other home improvements, householders can often recoup the cost of going electric. But payback time differs a lot. Quitting gas can rapidly pay itself off, while oversized home batteries can take much longer.

For our three pathways for a household with an EV, simple payback takes 5.4, 6.8 and 7.4 years respectively. Zero- or low-interest loans offered by some governments can reduce upfront cost, but will push payback time back roughly 2–3 years.

To optimise payback, it’s best to begin by improving the building to reduce energy use, shift away from gas to efficient electric appliances, use solar directly if available and then buy a home battery if warranted.The Conversation

Hydrogen microgrids could help power remote communities – but beware the hype

Md Alamgir Hossain, University of Southern Queensland

In remote towns, what happens when the sun fails to shine, the wind barely blows and batteries begin to run low?

Too often, the answer is another costly diesel delivery.

Australia is already investing in regional and remote microgrids, including two First Nations-led microgrid projects in the Northern Territory. Microgrids are small, controllable electricity systems that are powered by renewable energy and can operate independently of the national network.

Meanwhile, the federal government is exploring what opportunities renewable hydrogen may offer. Globally, we consume about 100 million tonnes of hydrogen each year – most of it fossil fuel-based – to produce everything from fertiliser to margarine. But Australia’s hydrogen ambitions have been shaken by cancelled projects and high costs. Internationally, uncertain demand and a lack of infrastructure are holding back hydrogen development worldwide.

Our recent study takes a practical look beyond the “hydrogen hype”. It suggests hydrogen could work alongside batteries in some remote microgrids.

Not just a replacement

Solar panels and wind turbines produce renewable electricity. Batteries store any surplus energy for later use, making them particularly useful when the sky is cloudy, winds ease or demand suddenly rises.

If more electricity is generated than the battery can store, a device called an electrolyser can split water into oxygen and hydrogen. The hydrogen is then stored and later fed into a fuel cell, which uses it to generate electricity. This allows renewable energy to be stored for longer periods and used when needed.

But this process has its downsides. Converting electricity into hydrogen and back again loses more energy than storing electricity in a battery. Hydrogen equipment is also expensive.

So hydrogen is not a replacement for batteries, but offers another option when longer storage is needed, diesel deliveries are costly, or several days of backup power are essential.

Combining forces

In our recent study, we tested an automatically controlled experimental microgrid. The system used real batteries and equipment that acted like renewable power sources, an electrolyser and a fuel cell.

We examined its performance under different scenarios to assess:

  • how the electrolyser responded to surplus power

  • how the fuel cell responded to a power shortage

  • how the whole microgrid handled changing demand.

Our results showed the system could respond to shifts in supply and demand while keeping the microgrid’s voltage close to its target of 380 volts. This is an important step in bringing this technology from the lab to the field.

Australia has also built a related field demonstration. The Denham project in Western Australia is the country’s first remote renewable hydrogen microgrid. It became operational in 2024 and was designed to store excess solar electricity as hydrogen for later use.

The Australian Renewable Energy Agency described this trial as a success. But it also identified challenges in delivering the project and making the hydrogen equipment work with other technologies.

Where to from here

Hydrogen microgrids may be most useful in places where reliable power is expensive or difficult to get, such as remote communities, islands and offshore operations. These locations often rely on diesel delivered by truck, ship or barge. And it can be costly to connect these communities to the main electricity grid.

But hydrogen microgrids won’t suit every remote community. Producing hydrogen requires purified water. In dry or offshore locations, supplying this water requires extra equipment, uses more energy and increases costs. Communities may also lack the resources or skills to keep electrolysers and fuel cells running.

Communities must first decide what level of reliability they need and what risks they are willing to accept. Possible risks include higher upfront costs, extra pressure on scarce water supplies, and delays in sourcing specialist parts or repairs. They should also consider whether public money would be better spent on another technology, such as larger batteries, pumped hydro or stronger transmission links.

Any proposed microgrid should be designed with local conditions in mind. The European Union’s REMOTE project tested three combined hydrogen-and-battery systems at isolated sites in Spain, Greece and Norway. The projects showed technical promise, but each site required a different design to match its energy supply and the needs of local customers.

Hydrogen is unlikely to replace batteries any time soon, but could be valuable in places where longer storage is essential. However, it’s ultimately up to communities to decide whether hydrogen is worth the investment – or is just another hyped-up technology.The Conversation

Australian beekeepers can’t tackle Varroa mite alone. Here’s how we can help

A close-up view of young bee with a Varroa mite on its abdomen.

For decades, Australia was the last inhabited continent free of the bee-killing Varroa mite (Varroa destructor).

That all changed in June 2022, when Varroa was detected near Newcastle and rapidly spread along the coast of eastern Australia. By September 2023, authorities had abandoned attempts to completely eradicate the tiny parasite.

So Varroa is here to stay. For beekeepers across Australia, that means learning to live with the risks of infested hives, lower production and lost income.

So, how are we currently managing Varroa? And what needs to change?

A deadly mite

The Varroa mite is a tiny parasite that attaches to honeybees and feeds on them, impairing their development, immunity and behaviour. These mites can also carry various bee-killing pathogens.

Varroa mites can wipe out entire colonies if left untreated. For this reason, they are considered the foremost threat to managed honeybee colonies worldwide.

Varroa can rapidly spread through human intervention, such as when a person moves infested hives or equipment between two sites. But these mites largely jump between hives through normal bee activities including “drifting”, where confused bees enter the wrong hive. “Robbing”, where bees from a strong colony plunder a weaker one for resources, is another common way Varroa spreads.

Australia’s response

In Australia, authorities have sought to bolster the industry and slow Varroa’s spread under a national management program, introduced in early 2024. Today, the scale of the problem varies from state to state.

Queensland, New South Wales and the Australian Capital Territory now have well-established Varroa populations. In these states, local apiarists have largely shifted to routine management, which involves regularly monitoring and managing mite levels through various treatments.

Varroa has been detected in multiple parts of Victoria and South Australia. However, both states are on high alert and are bracing for more widespread infestations this spring.

Western Australia, Tasmania and the Northern Territory are currently free of Varroa. To stay that way, they are strengthening early detection and border monitoring efforts.

How do we currently treat Varroa?

Effective Varroa management relies on three key principles.

1. Monitoring

Regular monitoring typically involves taking about 300 bees from a hive and washing them in alcohol or soapy water. This process kills the bees, but is a small and necessary sacrifice. It allows beekeepers to identify and count any mites, before deciding whether further treatment is needed.

2. Treatment

Varroa treatments can be costly and complicated. Finding miticides – a type of pesticide specifically designed to kill ticks and mites – that are toxic to the mite but do not harm bees is a tough task. Current chemical treatments can harm bees by reducing adult and brood survival or impairing how well adults function.

Some miticides can’t be used above certain temperatures or during nectar flows – the period when local plants bloom and produce lots of nectar. Most worryingly, Varroa mites can quickly become miticide-resistant. In the past three years, mites in most states have developed resistance to pyrethroid- and formamidine-based treatments.

Due to these limitations, many apiarists might view chemical treatment as a last resort and may first turn to chemical-free or biotechnical approaches. Biotechnical strategies disrupt the mites’ reproductive cycle by interrupting the production of bee brood – the eggs and larvae of honeybees – or trapping mites to be physically removed. However, many traditional biotechnical approaches require time and experience and may hamper the growth of the bee colony.

3. Post-treatment

Beekeepers can slow the spread of Varroa by keeping colonies well fed to prevent robbing. To reduce drifting, apiarists can also place hives further apart and face hive entrances in different directions.

Backing our beekeepers

We can better support our beekeepers by:

  • offering training and mentorship opportunities to help them share Varroa management knowledge and skills

  • splitting or donating colonies to apiarists who have lost hives

  • listening to industry-level concerns about the economic and operational pressures commercial beekeepers face and consider providing financial support, such as covering the costs of ongoing treatment and travel during pollination season

  • protecting and restoring forests to provide bees nectar and pollen.

Without support, the Australian Honeybee Council estimates almost 40% of commercial beekeepers will leave the sector in the coming years. This means there will be fewer bees pollinating crops – putting our farming communities and food security at risk.

Where to from here

Current Varroa management guidelines are largely based on data from other countries. So we urgently need more research to understand which management strategies work best in Australian conditions. We should also investigate ways to make biotechnical methods faster and easier to use.

There’s no silver bullet in the fight against Varroa. But in Australia, we have the benefit of time. As the world’s last major honey-producing country to detect Varroa, we can draw on three decades of global expertise and tailor strategies to our conditions. The future of our bees and beekeepers depends on it.The Conversation

Poor genetic health threatens many species – but it’s fixable

By the early 1990s, there were only around 20 Florida Panthers left on the planet.

A distinct and isolated population of the widespread Puma (Puma concolor), the Florida Panther was pushed to the edge of extinction by a range of threats. One major issue was their poor genetic health, a measure of how diverse an individual or population’s genes are and how related everyone is.

In 1995, researchers performed a daring “genetic rescue”. They introduced a handful of Texan Pumas to the Florida Panther population. These animals then interbred and helped the Panther population bounce back by bringing in new genetic material.

This example illustrates why genetic health matters. However, poor genetic health often gets overshadowed by other threats such as land clearing, invasive species, disease and climate change. That’s despite decades of research highlighting it as a crucial piece in the conservation puzzle.

A genetic health check

Scientists assess a species’ genetic health by taking small samples from individuals – of blood or hair for example – to compare the similarities and differences in their DNA.

This information helps us understand a species’ genetic makeup, including its levels of genetic diversity and inbreeding. These factors can indicate whether a species is more likely to flourish or go extinct.

The more genetic diversity a species has, the better. Diversity helps individuals and populations survive environmental changes such as disease, invasive species, bushfires and floods. A diverse population is more likely to already have individuals that can cope with the new conditions. Hence they pass down those very versions of genes that have helped them. This is the process of natural selection.

A related issue is inbreeding, where close relatives mate and produce offspring. Close relatives tend to carry the same harmful mutations in their genes, so their offspring can end up with no working copies of those genes. As shown by some historical royal families, the results can be disastrous – developmental problems, disease, lower fertility and early death.

These two factors – low genetic diversity and high inbreeding – combine to produce fewer offspring generation after generation.

A threat to many species

Poor genetic health can dramatically increase a species’ risk of going extinct. Studies of common non-threatened species – mammals, birds and plants alike – show inbred individuals have fewer surviving offspring than non-inbred ones.

Experimental studies confirm this too. In 1998, researchers established new populations of the Glanville Fritillary Butterfly (Melitaea cinxia) in empty meadows in Finland. Two-thirds of the populations with good genetic health survived their first winter, while populations with poor genetic health were all wiped out.

In general, threatened species are at greatest risk of poor genetic health. These species often live in small, isolated populations that lose genetic diversity much faster than larger ones. Within a small population, there are also fewer options for mating, so it’s not long before relatives interbreed.

Poor genetic health is a significant issue on its own. But it can also worsen other threats. For example, a series of heatwaves may drive a species into decline, triggering the loss of genetic diversity and an increase in inbreeding. This then means species may be less able to survive the next heatwave and so on, in a downward spiral towards extinction.

Despite this, genetic health is often overlooked in global recovery plans and conservation policies. This may be because of the perception that genetics is too complex or just isn’t relevant to conservation.

Not managing genetic health, due to inaction or legislative hurdles, can lead to extinction. Consider the Dusky Seaside Sparrow (Ammospiza maritima nigrescens). By the 1980s, only males remained, and they were successfully crossed with females of a related subspecies. But conservation legislation did not recognise the resulting “hybrid” offspring, meaning this conservation effort was abandoned. This sub-species is now extinct.

So, what can we do?

The case of the Florida Panther shows extinction is avoidable if we act before it’s too late. So do other examples such as the Helmeted Honeyeater (Lichenostomus melanops cassidix) and Mountain Pygmy Possum (Burramys parvus) in Australia. In each case, scientists carefully chose which individuals to move between distinct populations. The result was more offspring, better survival and populations starting to grow again.

To prioritise the genetic health of our most vulnerable plants and animals, threatened species managers should:

  • recognise the importance of genetic health, as outlined in our recent article

  • assess whether a species has poor, moderate or good genetic health. This helps identify which populations are most at risk, and what strategies will most effectively boost their genetic diversity

  • move small numbers of individuals between populations to reduce inbreeding and enhance genetic diversity, but only between populations of the same species that are from similar habitats. If their gene pools are too different, they won’t breed well. When done correctly, this simple action can have large and reliable benefits for survival and reproduction

  • create habitat corridors so individuals can move between different populations and limit inbreeding, effectively performing their own genetic rescues.

The public can contribute by:

  • getting involved with an environmental group or conservation organisation, and ensuring genetic health is part of any species recovery plan

  • advocating for habitat protection and government investment in species recovery.

We share our planet with a spectacular array of plants and animals. To help them thrive, it’s time we prioritise their genetic health and put it at the core of our conservation efforts.

Crocodiles can’t fly. Birds can. Scientists have finally figured out why

An egret and a crocodile

Roger S. Seymour, Adelaide University

The closest living relatives of crocodiles and alligators are, perhaps surprisingly, birds. They are both archosauriforms, a group of species that originated about 250 million years ago near the beginning of the Triassic period.

The group soon split into two lineages: one led to crocodiles (Pseudosuchia), while the other led to dinosaurs and then birds (Avemetatarsalia). This means there is a combined 500 million years of evolutionary change between modern birds and crocodiles.

The aeons have erased almost all evidence of shared ancestry. Crocodiles are cold-blooded (called ectotherms by physiologists). Their body temperatures are determined by the environment, and they have low metabolic rates (the speed at which their bodies turn food into energy). They appear sluggish, except for occasional brief flurries of powerful activity while drowning prey or fighting among themselves.

Birds are warm-blooded (or endotherms). They have high metabolic rates, producing energy quickly enough to warm and stabilise their body temperatures and to undertake sustainable, strenuous exercise of flight. Birds don’t fatigue and fall out of the sky.

Even if crocodiles somehow had wings, the metabolic difference in power alone would mean they could never fly.

How did birds and crocodiles become so different? The conventional assumption has been that their common ancestor was more like a crocodile than a bird – but our new research shows the opposite is most likely the truth.

The conventional picture

Scientists have assumed that warm-blooded animals evolved from cold-blooded ones, not the reverse. As warm-blooded creatures ourselves, we have had a habit of thinking warm-blooded animals are physiologically superior to cold-blooded ones.

By this logic, if a group of animals evolved to become warm-blooded, it could never revert to a cold-blooded state without quickly going extinct.

From this view, it makes sense to believe the crocodile lineage had been cold-blooded all the way from its origin. Scientists thought warm-bloodedness had appeared only in the dinosaur-bird lineage.

The conventional view: the common ancestor of crocodiles and birds was cold-blooded (or endothermic) rather than warm-blooded (ectothermic). Roger Seymour, CC BY

The new picture

Our first clue that the crocodile lineage was originally warm-blooded was that living crocodiles have four-chambered hearts. The only other groups with such hearts are warm-blooded birds and mammals, and there is a functional connection with warm-bloodedness.

High metabolic rates in warm-blooded animals require high rates of blood flow and high blood pressure. Four-chambered hearts completely separate low-pressure blood, going through pulmonary arteries to the lungs, from high-pressure blood travelling through systemic arteries to the rest of the body.

This pressure separation is vital to prevent high-pressure blood from reaching the lungs. If it does, it can cause a potentially fatal buildup of fluid which blocks oxygen uptake.

New research suggests both the crocodile and dinosaur-avian lineages started out warm-blooded, but the crocodiles reverted to cold-bloodedness relatively recently. Roger Seymour, CC BY

So modern crocodiles have a warm-blooded-style heart but produce the low blood-flow rates and pressures we would expect for their cold-blooded nature. This suggests their hearts were once evolved for warm-blooded life.

Because warm-bloodedness is associated with high rates of blood flow, we searched for fossil evidence of large blood vessels to accommodate high flow. We had earlier found that the holes in the the leg bones that pass blood vessels through the bones of living mammals were relatively much larger than those in living cold-blooded reptiles.

We checked this against these holes in ten species of dinosaurs, and confirmed that they too were warm-blooded. But we had no measurements from the earliest archosaurs, nor any from ancient members of the crocodile lineage.

Our new study of the hole size in fossil leg bones focused on the earliest archosaur relatives from both lineages we could find. Starting in 2018, we assembled data from 81 species, which showed that both the crocodile and dinosaur-bird lineages had high metabolic rates until relatively recently – perhaps around 66 million years ago, at the time most dinosaurs died out – when crocodiles abandoned it in favour of a cold-blooded metabolism.

These results are consistent with several other lines of evidence regarding the evolution of metabolism in the crocodile and dinosaur-bird lineages and also among mammals.

From active land-dwellers to watery ambush predators

The new view of the history of the crocodile lineage starts in the Triassic period, with them as active land-dwelling warm-blooded animals, in many cases even running on two legs. They diversified into hundreds of species over the Jurassic and Cretaceous periods, living on land, in salt and fresh water, and in between. However, they apparently remained warm-blooded until recently.

Why did their metabolisms slow down? We think it may have been related to their current behaviour as ambush predators in water. The low metabolic rates that come with being cold-blooded allow them to hold their breath longer to remain hidden while waiting for prey animals, and while drowning them.

There are no warm-blooded ambush predators in water alive today. Warm-blooded animals simply cannot hold their breath long enough.

Reversion to a cold-blooded metabolism may have saved the crocodile lineage from extinction 66 million years ago when an asteroid ended the lines of most dinosaurs, except, of course, the birds.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. 

Australian Native Foods website: http://www.anfil.org.au/

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.
