Australia should build more of its AI data centres in the north. The physical infrastructure that powers AI has become a strategic national security issue, not simply a collection of commercial assets but a critical component of Australia’s future energy, infrastructure and national-security planning. Where that infrastructure is built is now a national decision, not just a commercial one, and concentrating it in Sydney and Melbourne is a growing risk.
Northern Australia, with its energy resources, land, proximity to Indo-Pacific markets and rising strategic weight, is where a meaningful share of it should be located. What Australia lacks is a national siting strategy to make that happen.
The question is now live. In recent weeks, data centres have received increasing attention across the government, industry and the media, along with growing debate about where future facilities should be located and how their effects should be managed. Last week, Prime Minister Anthony Albanese outlined a vision for Australia to develop sovereign AI capability while announcing plans for national standards governing large-scale data centres. A Senate inquiry is examining the effects of AI and data centres, including their implications for energy systems and water resources. In New South Wales, a parliamentary inquiry is investigating the rapid expansion of data centres and the pressure they are placing on electricity networks, planning systems and urban infrastructure. At the same time, the Department of Home Affairs is introducing more prescriptive requirements for high-risk critical infrastructure, including data centres, energy networks and water supplies.
These developments recognise that data centres that power AI are becoming nationally significant infrastructure. But amid the focus on land constraints, planning approvals, electricity demand and environmental impacts, a more fundamental consideration has received less attention: where we should build the digital infrastructure that underpins economic prosperity, sovereign capability and national resilience.
Australia is a significant global data-centre market, supported by political stability, close links to Asia, extensive subsea cable connectivity, land availability and renewable energy potential. But Australia’s data centres, of which there are roughly 290, remain heavily concentrated in Sydney and Melbourne, reflecting historic local commercial factors rather than strategic considerations.
This creates a geographic concentration risk. The New South Wales parliamentary inquiry reflects the consequences of this concentration and projected growth within already constrained urban environments, but the issue is more than finding more space in two big cities; it’s whether critical infrastructure that supports government services, finance, industry, research and defence continue to be concentrated within a limited number of locations.
From a resilience perspective, diversification matters. A more geographically distributed network of data centres could improve Australia’s ability to withstand natural disasters, major power disruptions or cyber incidents. Australia has already recognised the importance of diversification in areas such as fuel security, critical minerals and supply chains. The same logic applies to the infrastructure that powers AI.
Northern Australia is where that diversification should start. Discussions at the Northern Territory Investment Summit, held on 17 July, highlighted how gas from the Beetaloo Basin could support future energy demand. The region’s significant gas reserves, abundant land availability and access to underground water resources have renewed debate about its role in enabling new industrial development. This is an example of where northern Australia’s energy resources can support nationally significant industries.
The Northern Territory offers significant renewable-energy potential, abundant land, proximity to Indo-Pacific markets and increasing strategic importance. It is also central to Australia’s defence posture and is emerging as a hub for critical minerals processing, space activities, undersea communications and industrial development. While each of these investments serves a distinct purpose, together they form a strategic industrial and national-security ecosystem – one that data centres would strengthen and draw strength from.
Locating data centres in the north also puts energy-intensive industries closer to where energy can be produced. Aluminium smelting, liquefied natural gas processing and minerals refining have historically been done near reliable energy sources, minimising the cost of moving the energy. Whether powered by gas, renewables energy or a combination of both, computing capacity should be developed where long-term energy availability is greatest, rather than adding further pressure to already constrained metropolitan electricity networks.
Australia’s debate over AI data centres has reached an important point. The federal and state inquiries, the government’s AI agenda and the growing focus on energy requirements all lead to the conclusion that data centres matter. The missing piece is a strategic framework for where they are built that is based on resilience, energy and strategic grounds, all of which point north.
Northern Australia is often viewed as Australia’s resource frontier. Increasingly, it should also be viewed as a place where Australia’s energy, digital, defence and economic interests converge. As AI reshapes the global economy, Australia has an opportunity to think differently about where the physical foundations of that economy are built. The priority is not simply building more computing capacity but building it in places that strengthen Australia’s resilience, sovereignty and strategic advantage. That means looking north.
