Anthropic Disclosed Plans for 5 Gigawatt Australian Data Center Buildout by 2030, Four Corners Reports

Anthropic disclosed to Australian government officials that it wants 5 gigawatts of new compute capacity by 2030 and a longer-term target of 20 gigawatts, according to an ABC Four Corners investigation published June 8. The figures, shared by sources close to the industry speaking on condition of anonymity, represent a substantial share of Australia’s total electricity output.

Former Australian chief scientist Alan Finkel told Four Corners the 20-gigawatt ambition “would represent an approximately 60 per cent increase on the electricity generation output of Australia.” He added: “To do that in a decade would be hard. To do that in five years would be extremely difficult.”

The MOU and the Energy Condition

CEO Dario Amodei visited Parliament House in Canberra in April and signed a Memorandum of Understanding with the government to “work together to capture the full benefits of AI for Australians,” according to Four Corners. In that MOU, Anthropic stated it “recognises the importance of expanding Australia’s energy supply and transmission with a focus on firmed renewables.” The agreement is not binding.

Anthropic would not confirm the specific gigawatt figures but told Four Corners it “wants to be an accelerator and a partner in Australia’s energy transition” and plans to “scale our demand, including through new generation; cover our own costs; contribute to grid resiliency through load flexibility; and partner with the community to ensure the benefits are broad and shared.”

The federal government declined to comment on the specifics, saying “discussions are commercial in confidence.”

A Crowded Field

Anthropic is not alone in targeting Australia. Microsoft CEO Satya Nadella announced A$25 billion in AI and cloud infrastructure investment in Australia by 2029, calling it “the largest ever company investment in Australia,” during a visit in April. Amazon has committed $20 billion, and OpenAI has partnered with NextDC on a proposed 650 MW AI facility at Eastern Creek in Sydney, according to the Sydney Morning Herald.

The combined demand is significant. The Climate Council’s June 2026 report found that if every proposed Australian data center project went ahead, combined maximum demand would top 21 gigawatts, more than seven times the capacity of Eraring, Australia’s biggest coal-fired power station. The Australian Energy Market Operator expects data center electricity consumption on the east-coast grid to triple by 2030, per the SMH.

The Energy and Regulation Tradeoff

Helen Toner, former OpenAI board member and now executive director of Georgetown University’s Center for Security and Emerging Technology, told Four Corners that “computing power is going to be a major source of national power” and that hosting significant compute capacity “will give us leverage potentially in the future because it’s such an important resource.”

But the investment comes with conditions the companies may not control. The Climate Council modelling, based on Baringa research, found that meeting data center demand growth with gas rather than renewables could push wholesale electricity prices up 26% in New South Wales and 23% in Victoria by 2035, according to the SMH. Energy ministers from all states except Queensland have agreed data centers should invest in additional renewables to offset their consumption, with rules due in July.

Anthropic is already hiring for the buildout. A job listing for “Data Center Energy Lead, Australia” posted in early June describes the role as “essential to ensuring Anthropic can scale compute capacity efficiently while navigating the complex dynamics of the National Electricity Market.”

The Geopolitical Infrastructure Play

The Four Corners report frames Australia’s attractiveness around four factors: energy access, water access, political stability, and exemption from U.S. chip export restrictions. For Anthropic, which is simultaneously pursuing a $35 billion chip financing deal with Apollo and Blackstone and building custom silicon, geographic diversification of compute is becoming a core competitive strategy alongside model research.

The question for Australia is whether hosting 5 to 20 gigawatts of AI compute translates into strategic leverage or merely into higher electricity bills. The answer depends on whether governments can enforce renewable energy commitments before the data centers come online.
