Australia’s AI infrastructure race has taken another major step, with Claude maker Anthropic signing its first Australian data-centre lease for capacity at a proposed giant computing campus in Queensland’s Western Downs.
The agreement puts one of the world’s best-known AI companies behind a project planned for farmland roughly 250 kilometres west of Brisbane. The wider campus is designed for up to 2.16 gigawatts of capacity, placing it among the largest proposed computing developments of its kind.
For Australia, the significance goes well beyond another overseas technology company opening an office. The physical infrastructure required to run advanced AI is starting to move closer to Australian users — and with it comes a much bigger debate about electricity, investment, local communities and who pays for the infrastructure needed to support the AI boom.
What Anthropic has agreed to in Queensland
Reuters reported on September 16 that Anthropic has signed a lease covering capacity at a data-centre campus being developed by Singapore-based Zerra DC. The proposed Western Downs facility is expected to begin coming online in 2027, although the deal remains subject to Foreign Investment Review Board approval.
ABC News separately reported that the proposed development near Dalby has been valued at around A$32 billion and is expected to become Australia’s largest data-centre facility if completed as planned.
Current reporting indicates Anthropic intends to use the Queensland capacity for AI inference rather than training. In practical terms, that means computing power would be used to run already-trained models, such as processing requests and generating responses, rather than carrying out the enormous training runs used to create new frontier models.
Why a 2.16GW AI campus matters
The number that immediately stands out is 2.16 gigawatts. That is the planned capacity of the broader campus rather than a statement that Anthropic will consume all of it from day one, but it illustrates how dramatically the scale of AI infrastructure is changing.
ABC News reported that the facility’s potential power draw is comparable with the average requirements of about 1.5 million Australian households. That comparison explains why data centres are quickly becoming an energy-policy issue as well as a technology story.
Reuters reported that the developer plans to source renewable power through purchase agreements and cover grid-connection costs, while the facility is expected to use a closed-loop, air-cooled system designed to reduce demand for clean water.
Australia is becoming part of the global AI infrastructure race
Until recently, much of the public AI conversation in Australia centred on access to services such as Claude, ChatGPT and Gemini. Increasingly, the more consequential story is what sits behind those services.
AI companies need enormous amounts of specialised computing hardware, land and reliable electricity. As established data-centre markets face tighter power and land constraints, Australia’s combination of available land, energy resources and political interest in technology investment is attracting attention.
Anthropic had already signalled that interest. Earlier in 2026, the company signed a memorandum of understanding with the Australian Government covering AI capability, safety, research and potential infrastructure investment. The Department of Industry said Anthropic planned to open a Sydney office during 2026 and explore further investment in the country.
The Queensland agreement turns some of that interest into a much more concrete infrastructure commitment.
What it could mean for Australian AI users
A large domestic inference facility does not automatically mean Claude will suddenly become faster or cheaper for every Australian user. Data-centre capacity is only one part of a complex global network, and the Queensland project still has approvals and construction milestones ahead of it.
But bringing more AI compute into Australia could give companies greater options for serving local workloads and potentially support businesses with requirements around latency, resilience or where data is processed.
It also raises questions that will become increasingly difficult to separate from the technology itself. Australia wants the investment, jobs and computing capacity associated with the AI boom, but hyperscale facilities require extraordinary amounts of energy.
That makes the real story bigger than Anthropic or Claude. Australia is positioning itself to host more of the infrastructure powering the AI era. The next question is how quickly it can build that infrastructure without shifting unreasonable energy, water or network costs onto surrounding communities.
What happens next
The Anthropic lease is subject to Foreign Investment Review Board approval, and the Western Downs project still needs to move through its broader development and construction process. Current plans point to the facility beginning to come online in 2027 rather than appearing all at once.
That distinction is important. This is a major agreement for a proposed facility, not a completed 2.16GW data centre.
Even so, the direction is increasingly clear: the global AI infrastructure race is reaching Australia, and Queensland now has one of its biggest proposed projects at the centre of it.
