Nine governments, one rulebook: National Cabinet backs mandatory AI and data centre standards

This affirmation provides an opportunity for developers, investors and operators across the energy, technology and infrastructure sectors, to plan ahead, even if much of the detail remains to be settled before legislation lands in early 2027.

What National Cabinet endorsed

First Ministers agreed that large data centres bring material energy, water and land-use impacts that need to be managed, and backed the Commonwealth's framework, announced by the Prime Minister on 15 July 2026, to set minimum requirements for large data centres through a nationally consistent regulatory framework.

The key features of the affirmation are as follows:

• The Commonwealth committing to work with State and Territory governments to develop consistent mandatory standards for data centre energy, water and land-use and to support skills and training opportunities. This is the first time all Governments have committed to a common set of mandatory standards.

• The Commonwealth confirming its legislation is designed to complement (not duplicate) State and Territory planning and approval processes. In other words, the national standards are intended to sit on top of existing planning regimes, not replace them. Accordingly, proponents will be required to comply with both Commonwealth standards on energy, water and land-use, plus usual state planning and environmental approvals.

• The Commonwealth affirming its intention to legislate the AI standards in early 2027, including conditions 'associated with delivering AI training', though it is not clear as to what this refers based on available information.

Inside the proposed mandatory data centre standards

The standards build directly on the Commonwealth's Expectations of data centres and AI infrastructure developers, released in March 2026, and are expected to apply to large-scale facilities, co-location sites, hyperscale operations and large-scale AI compute centres (rather than small edge or on-site enterprise data centres). Final coverage and thresholds will be confirmed through consultation.

National Cabinet endorsed three key aspects in relation to data centre impact and use, which we discuss below:

• Energy. The Government has signalled that large data centre operators must:

1. underwrite new power supply, effectively acting as "net generators" by adding at least as much energy to the grid as they draw from it;

2. pay their full share of transmission and distribution connection costs, so the cost of servicing data centres is not passed through to household and business energy bills;

3. adopt efficiency measures to minimise energy demand and emissions; and

4. support grid stability by reducing or shifting load when the system is under strain, through demand flexibility and peak-load management.

These obligations align closely with the tighter grid-connection settings already under development by the Australian Energy Market Commission, which we examined in Data centres and the grid: proposed reforms signal tighter connection rules. Operators should expect the national standards and the National Electricity Market reforms to reinforce one another.

In practice, these obligations are likely to be enforced by making compliance a precondition to entering the connection agreements needed to access the transmission network. NSW has flagged that it will legislate this, and the NSW transmission network service provider has already adopted a policy making compliance with several of the proposed obligations a precondition to grid connection.

However, after previously stating that data centres should be powered exclusively by renewables, the Commonwealth has agreed to a more energy-agnostic approach requested by Queensland and the Northern Territory, which have State-owned generation. While Minister for Climate Change and Energy Chris Bowen had consistently maintained the Commonwealth could 'override' States who were unwilling to require data centres to add firmed renewable generation, it is not clear whether this would have been possible.

• Water. Large facilities can place significant demand on local water systems for cooling. The standards are expected to require operators to minimise water usage, maximise water efficiency and pay for any additional water infrastructure their sites need. At State level, New South Wales has asked the Independent Pricing and Regulatory Tribunal to review water pricing for data centres so that charges better reflect the full cost of servicing them - a signal of where cost-recovery settings are heading nationally.

• Land use. The land-use pillar is the newest addition and the least developed. The Government's concern is that very large facilities should be located appropriately and should not crowd out competing land uses such as housing. Industry should expect the standards to steer large data centres toward suitable locations and to reinforce the importance of early, genuine community engagement - a theme running through the NSW parliamentary inquiry we discussed in Data centre of attention: unpacking NSW's Data Centre Inquiry's possible moves.

What this means for developers, investors and operators

The Government will consult closely with industry and trading partners on the design of the framework, with the Office of AI the primary point of coordination.

In practice, industry participants should treat the emerging standards not as a distant compliance hurdle, but as the framework for the next generation of Australian digital infrastructure. In particular:

• Energy sector. Generators, retailers, storage developers and network businesses should expect data centre demand to be tied tightly to new supply. The "net generator" obligation creates genuine commercial opportunities - long-term offtake, co-located generation and storage and behind-the-meter arrangements, but it also concentrates counterparty and delivery risk. Power purchase agreements, connection agreements and revenue models should be stress-tested against the proposed obligations and the parallel National Electricity Market reforms.

• Technology sector. Boards should ensure AI governance, third-party risk and procurement controls can withstand regulatory scrutiny. The "conditions associated with delivering AI training" flagged in the communiqué are a space to watch closely, as they may extend the framework beyond physical infrastructure.

• Infrastructure sector and investors. Developers, funds and financiers should continue to build the energy, water and land-use requirements into site selection, feasibility, financing and valuation work now, rather than waiting for the legislation. Foreign investors should also factor the framework into Foreign Investment Review Board planning, given the national interest framing the Government has consistently attached to these reforms.
