Australia Sets New Rules: Data Centres Must Serve the Public
The Australian federal government has released expectations that will reshape how data centres are approved. Companies seeking faster federal sign-off must demonstrate their projects support Australia's national interest, back the clean energy transition, use water responsibly, create local jobs, and build local capability.
Assistant Minister for Science, Technology and the Digital Economy Andrew Charlton said the government will prioritise projects aligned with those goals to ensure AI growth remains sustainable and maintains social license.
This marks a fundamental shift in how Australia treats data centres. They're no longer viewed as routine property or tech investments. They're now classified as major infrastructure with direct effects on power grids, water systems, land use and local communities.
Why this matters for government
Data centres are large facilities packed with computing equipment that stores, processes and moves data. They power cloud services, video calls, online banking, research and AI tools.
A single AI-focused data centre can consume as much electricity as 100,000 households. The largest ones under construction could use 20 times that amount.
Australia has over 250 data centres today. That number will grow as AI demand accelerates. These facilities bring jobs and investment, but they also create real costs for nearby communities.
The electricity problem
Data centres in Sydney already use about 4% of New South Wales' grid-supplied electricity. By 2030, that could reach 11%.
Nationally, the Clean Energy Finance Corporation estimates data centres could account for up to 11% of Australia's total electricity use by 2035. Meeting that demand would require another 3.2 gigawatts of renewable electricity generation and 1.9 gigawatts of battery storage to avoid price rises and extra emissions.
Data centres aren't automatically bad for the energy system. They could fund new renewable energy and grid upgrades-but only if government enforces the right rules.
The water challenge
Water demand depends heavily on cooling systems and water sources. Current estimates for Sydney range from 1.9% of water supply by 2030 to 15-20% by 2035.
Developers are already seeking between 5 to 40 million litres a day. Current use sits below 0.1% of Australia's total water, but future demand will depend on cooling choices and available sources.
The new federal expectations require data centres to use water sustainably, work early with utilities and communities, use non-potable water where possible, pay their share of infrastructure costs, and report water use transparently.
Land use conflicts
Data centres locate in major cities because they need strong power, fibre links, water and site access. This puts them in direct competition for industrial land already needed for logistics, urban services and housing supply chains.
New South Wales launched a parliamentary inquiry into data centres in January. It's examining electricity demand, grid impacts, water use, drought risk, noise, heat, traffic and whether data centre resource demands reduce housing supply.
The inquiry also asks who benefits and who bears the costs. Other states may need similar reviews because federal expectations alone cannot resolve state planning conflicts.
What the new policy requires
The new expectations should end the assumption that any data centre is acceptable simply because it brings private investment.
Under the new rules, data centre projects should bring their own clean power or fund it. They should use water efficiently and prefer recycled or non-drinking water. They should create genuine local jobs and skills. And they should be transparent about energy, water and environmental performance.
The path forward is not to block data centres-Australia will need more of them. The answer is to be selective about location, power source, cooling method and what they contribute to communities.
Essential infrastructure must meet the same test as any other major public works: serve the public, not just the market.
