Anthropic has taken its first real step into Australia’s AI infrastructure market. The company signed a long-term lease at a data centre site west of Brisbane, confirmed by the Queensland government on Wednesday. It’s a small piece of a much bigger ambition, and it says a lot about how the Anthropic Australia strategy is unfolding.
Background
Anthropic’s interest in Australia goes back to the National AI Plan agreement it signed with the federal government in March. Dario Amodei flew to Canberra, met with the prime minister, and put his name to a memorandum that talked about safety research, workforce training, and the possibility of local infrastructure investment.
At the time, nothing was locked in. The document didn’t name a single site, a single dollar figure, or a single megawatt of capacity. It was a statement of intent, not a contract.
What followed was months of reporting suggesting Anthropic’s actual ambitions were far bigger than the MoU let on. Internal government emails put the company’s interest in New South Wales alone at up to 5 gigawatts. Industry sources pointed to a national tender worth well over $20 billion. Some estimates floated a total Australian investment figure north of $100 billion.
Details
The confirmed piece of that puzzle is the Western Downs Digital Park, a 2.16-gigawatt project on a 725-hectare site near Dalby, about 250 kilometres from Brisbane. It’s being built by Zerra DC, a Singapore-headquartered developer with a roughly $32 billion budget for the project.
This makes it the largest data centre under development anywhere in the country, and Anthropic’s lease there is its first confirmed, signed commitment in Australia. Everything else so far, including a separate 300 to 500 megawatt contract reportedly being negotiated with CDC Data Centres, remains unsigned.
At full build-out across four phases, the Western Downs site would draw close to 47 gigawatt-hours of electricity a day. Queensland’s entire state currently uses around 170 gigawatt-hours daily, so this one project alone could add somewhere close to a quarter of that on its own.
Quotes
Federal Industry Minister Tim Ayres has described the relationship with Anthropic around the idea of harnessing AI responsibly, tying it back to the National AI Plan framework the government launched in late 2025.
On the Queensland side, Premier Crisafulli has repeatedly said the state, not federal ministers, should decide its own energy mix for projects like this. He has also insisted new data centres need community benefit agreements with local councils before any development application goes ahead, a stance that puts Queensland at odds with the federal government’s push for stricter renewable energy rules.
University of NSW AI researcher Toby Walsh has offered a more sceptical read, arguing that the national security case for hosting AI training operations locally doesn’t really hold up, even as data centre investment gives companies leverage in unrelated policy fights like copyright reform.
Impact
The scale here is genuinely unusual. Australia’s total existing data centre capacity sits at roughly 1.6 gigawatts, according to industry estimates. One project, for one tenant, now proposes to add more than that on a single regional site.
That creates real upside for Queensland: construction jobs, long-term operational employment, and a marquee project other states will be compared against. It also creates real friction. Energy demand at this scale strains grid planning, water use draws scrutiny even with air-cooling designs, and local communities near Dalby will be living next to a facility built at a scale the region has never seen.
There’s a policy angle too. AI companies negotiating multi-billion dollar infrastructure deals gain real weight in conversations happening at the same time, including the government’s ongoing review of copyright settings for AI training data. Groups representing writers and musicians have warned that investment promises shouldn’t be used as leverage to water down creator protections.
Conclusion
One signed lease doesn’t settle where Anthropic’s broader Australian ambitions land. The company is still weighing multiple site options, still reportedly chasing gigawatt-scale capacity in other states, and still hasn’t confirmed the scale of any direct investment it might make of its own.
What Wednesday’s announcement does confirm is that the interest reported over the past year wasn’t just talk. Queensland has aned tenant, a $32 billion project moving forward, and a template other states will now be racing to match.
Frequently Asked Questions
Are Anthropic building data centres in Australia?
Not directly, at least not with this deal. Anthropic has signed on as a long-term tenant at the Western Downs Digital Park, a facility being built and owned by Zerra DC rather than by Anthropic itself. The company’s March memorandum of understanding with the Australian government does leave room for Anthropic to invest directly in local data centre and energy infrastructure in future, and it has been building out a Sydney-based team to manage its Australian compute strategy, but the confirmed activity so far is a lease, not a build.
Where are Anthropic data centers located?
In Australia, Anthropic’s only confirmed site is the Western Downs Digital Park near Dalby, roughly 250 kilometres west of Brisbane in regional Queensland. Globally, Anthropic has previously committed to major US-based infrastructure, including facilities in Texas and New York built through a partnership with Fluidstack, alongside its existing cloud computing arrangements with partners like Amazon and Google. Reports also suggest the company has been exploring additional leasing deals in Europe.
Who is the biggest data center company in Australia?
Established operators like NEXTDC and AirTrunk have historically held the largest footprints among Australia’s data centre companies, built up over years of colocation and hyperscale development across the country. The landscape is changing quickly, though. Zerra DC’s Western Downs Digital Park is now the single largest data centre project in the country by both cost and planned capacity, despite Zerra DC being a relatively recent entrant compared to Australia’s long-established data centre operators.
