Reported 16 Sept 2026 Infrastructure

Anthropic signed for an Australian data centre of up to 2.16 gigawatts, and it will run on coal and gas.

On September 16 Anthropic signed an agreement to take capacity at Western Downs Digital Park, a 32 billion Australian dollar campus near Dalby in inland Queensland developed by the Singapore-based firm Zerra DC, with peak capacity of up to 2.16 gigawatts and first use targeted for 2027. It is the company's first Australian site and its largest announced outside the United States.

The caveat is the power: Queensland's government negotiated for the campus to draw on the existing coal and gas grid rather than waiting for renewables, and the state premier is selling it as a way to drive down power prices, four days after Anthropic's chief executive published an essay arguing the industry should slow the pace of frontier development.

Until now

Anthropic's compute was an American story with a European edge, and its public argument was about pacing the frontier.

Now

Treat Anthropic as a global site developer whose next gigawatts are contracted on a coal and gas grid, and read pacing as a claim about model releases rather than about buildout.

On September 12 Anthropic's chief executive published an essay arguing that the industry should slow down at the frontier, and the company committed to giving outside evaluators desks and laptops. On September 16 the same company signed for 2.16 gigawatts of peak capacity on a 725 hectare site in inland Queensland, at a campus carrying a 32 billion Australian dollar figure, staged over four to six years and coming online from 2027. It is the largest site Anthropic has attached its name to outside the United States. The workload is inference rather than training, which is the part of the business that grows with customers, and the state premier greeted it as a way to put more energy into Queensland's grid and drive down power prices.

The power is the part worth reading twice. Queensland did not require the campus to wait for renewables. It negotiated the opposite: the site draws on the existing coal and gas grid until new generation is built, which for a load of this size means years of fossil generation running harder than it otherwise would. No new transmission is needed and Anthropic pays the full connection cost, which is exactly the arrangement the United States House voted 417 to 3 to make a federal standard on the same day, and the same day Anthropic joined an alliance whose founding idea is that data centres should reduce demand when the grid is tight. None of that is contradiction on its face. A company can hold that models should be released slowly and that serving capacity should be built fast, and Anthropic has never said otherwise. But the two arguments now have different units. One is measured in evaluation access and release dates. The other is measured in gigawatts on a coal grid in 2027. Treat Anthropic as a global site developer whose next gigawatts are contracted on a coal and gas grid, and read pacing as a claim about model releases rather than about buildout.

Sep 16
Anthropic signs for capacity at the Queensland campus, subject to Foreign Investment Review Board review, on a grid the state negotiated to keep on coal and gas until renewables arrive.
Who has to react
The Foreign Investment Review Board and the Australian Treasurer, who can stop this; the Queensland Premier, who has staked a price promise on it; the Western Downs Regional Council, sitting on the development application; AEMO and the Queensland generators who will be asked to firm a constant multi-hundred megawatt load; every Australian household told this will lower their bill; the climate groups who will read the coal and gas line first; Google, Fortum and the Finnish nuclear arrangement carded in Edition 017, which is the counterexample; and Anthropic's own evaluators, whose remit covers models and not megawatts.

The evidence

The agreement is reported by the Australian Broadcasting Corporation, Capital Brief and the trade press, and the site's development application is on file with the Western Downs Regional Council. Anthropic's newsroom carries nothing dated September 15, 16 or 17; we found no Queensland government release and no Zerra DC statement. Verification event, October 31, 2026: an Anthropic newsroom post naming the Queensland site, a Zerra DC or Australian Data Centres announcement, a Queensland government media statement, or a Foreign Investment Review Board record of the transaction. Absent one of those, this stays Reported and we will say so.

ObservedWednesday September 16, 2026. Anthropic signed an agreement to lease capacity at Western Downs Digital Park, a site of about 725 hectares near Dalby in the Western Downs region of Queensland, Australia.

The whole observation, as recorded

The developer is Zerra DC, headquartered in Singapore, with Macquarie Capital and the Dexus-backed Australian Data Centres in the consortium. The headline figure carried by the Australian Broadcasting Corporation is 32 billion Australian dollars, about 21 billion US dollars at current rates. Peak campus capacity is reported at up to 2.16 gigawatts, a draw the ABC compared to 1.5 million average Australian households. The documentation covers the first stage only; build-out is staged over four to six years with capacity coming online from 2027, and Anthropic is targeting operational use in 2027. About 1,000 ongoing jobs are attached to the project. The development application was lodged with the local council last month, and the lease is subject to review by Australia's Foreign Investment Review Board. On power: Capital Brief reports the campus will run on coal and gas until renewables are built, after the Queensland government negotiated for a mixed supply rather than a renewables-only condition. No new transmission is required and Anthropic covers the full cost of grid connection, which is the arrangement the United States House voted for on the same day. Queensland Premier David Crisafulli: this is a major win that will deliver more jobs, put more energy into Queensland's grid and drive down power prices. The site is for inference, the serving of answers to users, rather than for training. Against the company's own record: Dario Amodei published the pacing essay on September 12, carded in Edition 020; Anthropic committed to embedded outside evaluators the same day; its last published compute expansion is the Google and Broadcom agreement of April 6, 2026, which named multiple gigawatts of TPU capacity from 2027 and said the vast majority would sit in the United States; a reported 35 billion dollar compute agreement was carded in Edition 007. Anthropic also joined the AI Energy Management Alliance launched the same day, recorded below.

Established

The Australian Broadcasting Corporation reported on September 16, 2026 that Anthropic signed an agreement for capacity at a 32 billion Australian dollar data centre near Dalby, Queensland, developed by Zerra DC.
The campus has a reported peak capacity of up to 2.16 gigawatts, is about 725 hectares, and is staged from 2027 over four to six years.
Capital Brief reported the campus will run on coal and gas power until renewables are built, following negotiation with the Queensland government.
The lease is subject to Foreign Investment Review Board review and the development application is before the Western Downs Regional Council.

Not established

That Anthropic has committed 32 billion Australian dollars. The figure is the campus, the documentation covers the first stage, and no Anthropic share has been published.
That 2.16 gigawatts will be built. It is a peak ceiling for a fully built campus, and staged projects routinely stop short.
That Anthropic has abandoned clean power. The company has not published anything about this site, including its supply arrangements after the first stage.
That pacing was insincere. Release pacing and capacity building are different decisions, and nothing here contradicts what the company actually said on September 12.

Why it weighs this much

CostHigh

CommitmentMedium

ReversibilityMedium

PersistenceYears

Cost is high. A campus of this size is a capital commitment measured in tens of billions and a grid connection paid for by the tenant, and signing a first-stage lease puts a name on the development application. Commitment is medium rather than high because the documentation covers the first stage only, the headline figure belongs to the whole campus rather than to Anthropic's share, and none of it is final until the Foreign Investment Review Board is done. Reversibility is medium: staged leases can be walked away from between stages, and regulatory review can end it outright, but the site and the connection studies persist whoever occupies them. Persistence is years, because generation and interconnection decisions made for a load like this outlive any tenant. The bars would be higher if Anthropic had published anything about it.

What to watch

strengthens The Foreign Investment Review Board clears the lease and the Western Downs Regional Council approves the development application, or Zerra DC announces the first-stage energy supply arrangement, by March 31, 2027.
weakens The agreement lapses or is refused on review, or Anthropic publishes a renewables-only or nuclear supply commitment covering the Queensland site, by March 31, 2027.

The words

Inference: Running a finished model to answer users, as opposed to training, which builds it. Inference is the part of the workload that grows with customers rather than with research, and it has to sit near demand.
Peak campus capacity: The most electricity the whole site could draw when fully built. It is a ceiling across all stages, not what the first building will use.
Foreign Investment Review Board: The Australian body that screens foreign purchases and leases of Australian assets and advises the Treasurer, who can block them. Its review is why this agreement is not yet final.
Firming: The dispatchable generation, usually gas or coal, that keeps a grid steady when wind and solar are not producing. A constant industrial load like a data centre needs it around the clock.
