Demand for AI and cloud services is driving a new wave of data center investment across Australia, but growing scrutiny around power, water and infrastructure planning is changing how these facilities are developed.

Governments are increasingly positioning digital infrastructure as part of broader economic and AI strategies. In Victoria, the state government recently launched a Sustainable Data Centre Action Plan tied to a reported $25 billion digital infrastructure pipeline, including plans to map future developments against energy and water availability.

At the same time, the NSW Government has moved 15 data center projects through its Investment Delivery Authority as demand for AI and cloud infrastructure accelerates. Tens of billions of dollars of capital have already been committed to future data center projects in Australia, with national capacity projected to more than triple by 2035 as operators continue expanding AI and cloud infrastructure.

As hyperscale developments move through the pipeline, governments are increasingly focused on the pressure growing demand could place on electricity networks, water resources and planning systems.

The new rules shaping data center growth

Australia’s data center sector is entering a new phase of regulatory oversight. The Federal Government’s recently announced national interest framework for data centers and AI infrastructure provides a compass for future regulation, as governments attempt to keep national interests in energy, water and infrastructure at the forefront of the sector.

The framework sets out five key areas developers are expected to address as part of project approvals. These include aligning projects with Australia’s strategic and economic interests, supporting the energy transition, managing water sustainably, investing in local skills and strengthening Australia’s own digital capability.

The framework prioritizes national interests in energy, water and infrastructure as part of data center approvals, particularly as governments respond to the growing resource demands. It also reinforces the focus on sovereign capability to ensure Australia’s own digital capability can be independently controlled from within Australia, avoiding reliance on or influence from other countries.

Energy, water and infrastructure constraints

Access to reliable power is becoming one of the defining challenges in data center development, with many developers exploring alternative power sources and renewable energy to keep projects on track. AI usage is expected to increase power requirements for data centers by 150 to 200 per cent.

The federal framework makes clear that developers are expected to reduce pressure on the electricity grid by underwriting renewable energy, financing grid connections and participating in demand-flexibility programs that shift grid usage depending on network availability.

Water usage is also becoming a more prominent consideration as governments respond to the cooling demands associated with hyperscale facilities and AI infrastructure. The framework states that operators must adopt efficient technologies and practices that promote sustainable water management.

Beyond energy and water, developers are facing broader construction and delivery constraints. Rising construction costs, constrained power access, labor shortages and long lead times for specialized equipment are all affecting how quickly facilities can be delivered.

Land availability and planning regulation are growing areas of concern for developers. Regulatory bodies can take considerable time to issue approvals, while opposition to some data center developments is further slowing construction activity.

Why modular construction is gaining momentum

These pressures are contributing to increased interest in modular construction methods. Rather than relying entirely on conventional on-site construction, modular data centers use prefabricated modules containing structural, electrical, plumbing and cooling systems that are manufactured off-site before installation.

Designing, building and testing modules in controlled environments can reduce delays caused by severe weather conditions, labor shortages and other factors that typically affect conventional on-site construction. Modular construction can provide greater cost predictability and faster project delivery.

Modular construction also allows developers to scale projects incrementally as demand grows. Developers can begin with a base configuration and expand capacity with additional modules, particularly where standardized power and cooling mechanisms can be more easily controlled in prefabricated environments.

The increasing use of modular construction is influencing broader energy strategies around data center development. Off-site construction can support earlier commissioning and improve alignment between renewable energy provision and construction milestones where renewable power sources are available.

While modular construction can improve delivery speed and cost predictability, it does not remove the underlying infrastructure constraints affecting the sector. Developers still need access to sufficient power, land and network capacity, while planning approvals and sustainability requirements are becoming increasingly significant factors in project delivery.

States are taking a more active role

As hyperscale developments and AI infrastructure continue to expand, governments are placing greater focus on the pressure growing demand may place on energy and water resources.

The NSW Government recently announced that 15 data center projects will progress through the NSW Investment Delivery Authority at a time when about half of Australia’s planned data center capacity is clustered in Sydney.

Data center developments now account for approximately 12 per cent of all non-residential building investment in the state. However, around $40 billion worth of projects were not endorsed because they were considered too speculative or lacked sufficient preparedness.

Victoria’s Sustainable Data Centre Action Plan points to a similar policy direction, with Melbourne expected to host around 25 per cent of Australia’s planned data center capacity. State governments are increasingly moving beyond passive infrastructure approvals toward more active coordination of energy, water, planning and workforce settings for AI infrastructure development.

With critical infrastructure projects already moving through the planning process, governments are facing increasing pressure to ensure energy, water and broader state interests remain protected as the sector continues to grow.

As AI and cloud demand continue to accelerate, governments are paying closer attention to how data centers are planned, powered and integrated into existing infrastructure systems.

The next phase of Australia’s data center expansion is likely to depend not only on how quickly projects can be delivered, but on how effectively energy, water and planning systems can support that growth.
