Australia's data centre boom risks climate vulnerabilities without strategic planning

An asset to the energy grid, not a strain
Energy Minister Chris Bowen on what the federal government expects from data centre development.

As artificial intelligence reshapes the global economy, Australia finds itself at a crossroads familiar to any society caught between opportunity and foresight: the nation is building data centres at historic speed, yet the land beneath them is growing less predictable by the decade. Climate scientists and planners are asking a question that echoes through every era of infrastructure expansion — not merely whether we can build, but whether we are building wisely. The window to answer that question well is open now, and it will not remain so indefinitely.

  • Australia's data centre investment has surged from $460 million to $6.8 billion in a single year, driven by AI demand that shows no sign of slowing — and the approvals pipeline is accelerating faster than the planning frameworks meant to guide it.
  • Climate risk analysis reveals that Australia faces some of the steepest increases in infrastructure vulnerability over time, with extreme heat, flooding, and bushfire threatening facilities in NSW, Queensland, and Western Australia.
  • The cooling systems, power grids, water supplies, and telecommunications networks that data centres depend on are all exposed to the same climate disruptions — meaning a single extreme event could cascade across multiple layers of critical infrastructure.
  • Planners and policy experts are urging governments to map ideal data centre locations before the approvals phase accelerates, drawing on the renewable energy zone model as a proven template for strategic front-end planning.
  • Australia's data centre capacity is forecast to more than double by 2030, and the decisions being made right now about siting, engineering standards, and resilience investment will determine whether this infrastructure remains viable — and insurable — for decades to come.

Australia is building data centres at a pace it has never seen before. With 162 already operating and another 90 in development, investment has surged from $460 million in 2023 to $6.8 billion this year alone. The driver is artificial intelligence, which needs vast physical infrastructure to function, and Australia has become an attractive host: land is available, renewable energy potential is strong, and the regulatory environment is stable.

But a critical question is emerging alongside the construction cranes: are these facilities being built in the right places? Analysis by climate risk firm XDI of nearly 2,600 planned data centres worldwide found that roughly 6 percent face serious exposure to climate-related damage. In Southeast Asia, one in five planned centres already sits in a high-risk zone — a figure expected to triple by century's end. Australia ranks 22nd globally for current risk, but faces some of the steepest increases over time. Flooding threatens facilities in New South Wales and Queensland, bushfire poses extreme danger to a planned Western Australian centre, and rising temperatures will strain cooling systems designed around historical climate norms. As XDI's Karl Mallon notes, the infrastructure supporting data centres — power, water, telecommunications — is equally exposed.

The federal government has begun setting expectations: new projects should co-locate renewable energy and battery storage, minimise water use, and build community support. Energy Minister Chris Bowen has framed digital infrastructure as something that should strengthen the energy grid rather than burden it. Most states have agreed that data centres should fully offset their energy consumption with additional renewable generation, though Queensland has asked for more detail before committing.

Planning experts argue the sequencing is wrong. Nicole Bennetts of the Planning Institute of Australia says strategic mapping needs to happen before the approvals process accelerates — identifying locations with grid connectivity, minimal climate risk, and appropriate distance from residential areas. The model already exists: renewable energy zones were identified through exactly this kind of upfront strategic process. Applied to data centres, such planning could actually speed up approvals by giving investors clarity about which locations are viable, without requiring a moratorium.

Australia's data centre capacity stood at 1.4 gigawatts in 2025 and is forecast to exceed 3 gigawatts by 2030. For a country long dependent on mining and resources exports, digital infrastructure represents a rare opportunity to diversify. But seizing it well means building in the right places, with the right protections — while the momentum can still be shaped.

Australia is building data centres at a pace it has never seen before. The country now hosts 162 of them, with another 90 in the works. Investment has exploded from $460 million in 2023 to $6.8 billion so far this year. The reason is straightforward: artificial intelligence needs somewhere to live, and Australia has become an attractive address. The land is there. The renewable energy potential is there. The regulatory environment is stable. The Asia-Pacific region is nearby. But as these facilities come online faster than ever, a critical question is being asked: are we building them in the right places?

Data centres are thirsty, power-hungry machines that run around the clock. They cool servers, store information, stream entertainment, power cloud services. They are essential to modern life. Yet they are also vulnerable to the very climate disruptions that are reshaping the planet. A team at XDI, a company that analyses physical climate risk, examined nearly 2,600 planned data centres worldwide and found that 154 of them—about 6 percent—face serious exposure to climate-related damage or operational failure. In Southeast Asia, the problem is acute: one in five planned data centres already sits in a high-risk zone, a figure expected to at least triple by the end of the century.

Australia ranks 22nd globally for climate risk to data centre infrastructure, which might sound reassuring until you learn the rest: the country is experiencing one of the steepest increases in risk over time. The threats are specific and varied. Flooding could disable facilities in New South Wales and Queensland. Bushfires pose extreme danger to a planned centre in Western Australia. But the most pressing challenge is heat. As temperatures climb, the cooling systems designed around historical temperature ranges will struggle. "We design them on what our normal temperature range is," Karl Mallon, the director of science and technology at XDI, explained. "Our temperatures are going to go up quite a lot and therefore we need to be thinking about extreme heat and extremely hot days as being something that we need to plan for." The problem extends beyond the data centres themselves. The electricity supply, telecommunications connections, and water systems that support them are equally at risk.

The appeal of Australia to investors is real and understandable. The United States, home to more than 5,000 data centres, is running into constraints around energy availability and suitable locations. Global demand for digital infrastructure remains high. Australia offers what others cannot easily provide: abundant land, renewable energy potential, and a regulatory framework that welcomes investment. Melbourne and Sydney have emerged as the primary hubs, with facilities clustering in industrial areas on the urban fringe where power, fibre, water, and workforce access converge. Some operators are now using artificial intelligence itself to help choose where to build, factoring in climate risk and community concerns into their site selection models.

But the speed of development is outpacing the depth of planning. The federal government has issued expectations for new data centre projects: they should co-locate renewable energy and battery storage, minimise water use through innovative solutions, and build community support. Last month, energy and climate ministers from all states except Queensland agreed that data centres should fully offset their energy consumption with additional renewable generation. The Energy Minister, Chris Bowen, framed it plainly: digital infrastructure should be "an asset to the energy grid, not a strain." Queensland pushed back, asking for more detail on costs and risks before committing to a national standard.

Planning experts are sounding an alarm about the sequence of decisions being made. Nicole Bennetts, head of policy and advocacy at the Planning Institute of Australia, argues that strategic planning needs to happen before the approvals process accelerates. "It's about doing the strategic planning at the front end so that we can say these are the best locations for data centres," she said. The model exists: renewable energy zones were identified through an upfront strategic process that mapped the best locations for wind and solar generation. A similar approach for data centres could identify areas with grid connectivity, minimal climate risk, and appropriate distance from residential zones. This would not require a moratorium like Singapore imposed in 2019, but rather a deliberate mapping of where these facilities should go, done in parallel with assessing individual proposals. Such planning could actually speed up approvals by giving investors certainty about which locations are viable.

Australia's data centre capacity stood at 1.4 gigawatts in 2025 and is forecast to exceed 3 gigawatts by 2030. Beyond that, the forecast becomes uncertain, dependent on large projects clearing the planning stage. The window for shaping this infrastructure is open now. The decisions made today about site selection, engineering standards, and resilience investment will determine whether these assets remain operational, insurable, and economically viable over their intended lifespans. For Australia, the stakes are high. Digital infrastructure represents what some see as a once-in-a-generation opportunity to diversify an economy long dependent on mining and resources exports. But seizing that opportunity requires building in the right places, with the right protections, before the momentum becomes too difficult to redirect.

The question is no longer simply where the next generation of digital infrastructure gets built, but whether those assets can remain operational, insurable and economically resilient over their intended life.

Why does it matter where a data centre gets built? They all do the same job, don't they?

Model

They do the same job, but not in the same conditions. A data centre in a flood zone or a bushfire corridor faces real operational risk. If it floods, it stops working. If the cooling water runs out during a drought, it stops working. If extreme heat overwhelms the cooling system, it stops working. And when it stops, so does everything it supports—cloud services, streaming, AI applications. The location determines resilience.

Inventor

But Australia seems like a safe choice. It's stable, it has renewable energy, it's not like it's a war zone.

Model

That's true, and that's why investors are coming. But climate change is rewriting the risk map. Australia isn't facing the same hazards as Southeast Asia, but it's facing steeper increases in risk over time. Extreme heat is the key one. The cooling systems are designed for historical temperatures. When temperatures exceed those ranges, the infrastructure becomes vulnerable.

Inventor

So why not just build better cooling systems?

Model

You can, but it costs more, and it requires planning ahead. If you're rushing to approve sites without thinking about climate exposure, you end up building in places where you'll need to spend extra money on resilience later—or where the infrastructure becomes uninsurable. That's the real risk.

Inventor

Is Australia actually rushing, or is this just a precaution?

Model

The numbers suggest rushing. Investment jumped from $460 million to $6.8 billion in three years. Ninety new data centres are in the pipeline. The federal government is setting expectations, but there's no comprehensive map of where these should go. Queensland is resisting a national energy offset requirement. It feels like the approvals are moving faster than the strategic thinking.

Inventor

What would strategic thinking look like?

Model

Identifying zones where data centres make sense—where there's grid connectivity, renewable energy potential, minimal climate risk, and distance from homes. Then assessing individual proposals against that map. It's what they did with renewable energy zones. It would actually speed up approvals because investors would know which locations are viable before they invest in planning applications.
