Anthropic has signed an Australia data center lease covering capacity at Zerra DC’s planned 2.16-gigawatt Western Downs campus in Queensland, according to Reuters and Australian reporting. The agreement would give the Claude developer its first data-center foothold in the country.

 

The scale is substantial, but the project is not yet an operating facility. Construction and foreign-investment approvals remain outstanding, the campus is expected to start coming online in 2027, and the full 2.16GW would be delivered in stages rather than switched on at once.

 

The reported agreement has four defining terms:

  • Capacity at a planned 2.16GW campus near Dalby, Queensland.
  • Compute intended for Claude inference rather than model training.
  • A phased start targeted for 2027.
  • Completion subject to regulatory and development approvals.

 

Anthropic Australia Data Center Lease Covers 2.16GW

Reuters reported the lease based on two people familiar with the agreement. Anthropic and Singapore-based developer Zerra DC declined to comment, an important qualification for a transaction whose commercial terms and delivery commitments have not been published.

 

The Western Downs Digital Park is proposed for farmland roughly 250 kilometers from Brisbane and about 37 kilometers from Dalby. Earlier development reporting describes a campus of four large data-center buildings on approximately 725 hectares, built across four stages over several years.

 

Local reports value the broader project at about A$31.9 billion. That figure refers to the proposed campus, not a disclosed payment by Anthropic, and it should not be treated as the lease value. Reuters said the agreement covers planned capacity but did not publish its price or duration.

 

The facility would process inference workloads: the rapid calculations used when Claude responds to customer prompts. Training frontier models requires a different pattern of intensive, long-running computation, and Reuters’ sources said the Queensland site would not be used for that purpose.

 

Western Downs Still Faces Multiple Approvals

The campus is subject to review by Australia’s Foreign Investment Review Board and must progress through local planning and infrastructure processes. A lease for future capacity therefore does not guarantee that every phase will be approved, financed or connected to the grid on the proposed timetable.

 

Zerra’s plan places the campus near the Braemar generation hub and substation. The developer is expected to fund required grid connections and upgrades rather than passing those costs directly to existing electricity customers, according to people cited by Reuters.

 

Power sourcing is likely to receive close scrutiny. Reuters said Zerra would use renewable power-purchase agreements, while Australian reporting has raised questions about whether early stages could rely partly on gas before additional wind, solar and storage projects are available.

 

Water use is another regulatory focus. The proposed design uses air cooling and a closed-loop system intended to reduce demand for clean water. Local authorities are nevertheless setting tougher expectations as communities question how hyperscale facilities may affect regional power, water, roads and agricultural land.

Australia Competes for Frontier AI Infrastructure

Australia is pitching abundant land and renewable-energy potential to AI companies seeking capacity outside congested American and Asian markets. OpenAI reached an offtake agreement for a Sydney data center last year, and Nvidia recently outlined partnerships that could add as much as 2GW of Australian AI capacity.

 

Anthropic already has a formal relationship with the federal government. In March, the company signed an AI-safety memorandum covering model evaluations, research collaboration and economic data, alongside A$3 million in Claude credits for Australian institutions.

 

The lease would add physical infrastructure to that policy relationship. Locating inference capacity in Australia can reduce distance to customers in the region, diversify the company’s compute footprint and place more processing under Australian jurisdiction, though the available reporting does not specify data-residency guarantees.

 

Australia’s government continues to court data-center investment while promising tighter resource standards from 2027. Economists cited by Reuters estimate the investment pipeline could reach A$150 billion by 2030, increasing pressure on regulators to balance economic gains with grid and environmental constraints.

 

Claude Demand Moves From Models to Megawatts

For Anthropic, the agreement reflects a shift from buying individual clusters toward securing entire campuses. Model companies increasingly compete not only on software performance but also on access to power, land, network connections and facilities capable of hosting large quantities of accelerators.

 

A 2.16GW headline does not describe hardware installed on day one. It represents the campus’s proposed maximum capacity, and actual Anthropic usage will depend on phased construction, equipment delivery, grid availability and customer demand. Those variables can change over a multi-year build.

 

The next concrete milestones are regulatory approval, a confirmed construction schedule and details on the first capacity tranche. Until those emerge, the lease is best understood as a strategic reservation of future inference capacity at one of Australia’s most ambitious proposed computing sites.
