• Macquarie Capital, Singapore’s Zerra DC and Dexus-controlled Australian Data Centres have signed Anthropic to a long-term lease at the Western Downs Digital Park near Dalby, Australia’s single largest data centre project at roughly $30 billion.
• That’s about six times Goodman’s A$5 billion Eastern Creek build and fifteen times NextDC’s A$2 billion Port Melbourne project, the next-largest Australian data centre deals still working through approvals and financing. One site at Western Downs is worth close to a fifth of CommBank’s $150 billion forecast for the entire national pipeline through 2030.
• The 725 hectare site, currently a feedlot for 24,000 cattle, was chosen for proximity to three gas plants, a solar farm and existing transmission infrastructure, and its development application allows stage one to run on gas or grid electricity.
• Three weeks after David Crisafulli secured Queensland’s right to a “technology agnostic” energy mix at National Cabinet, the country’s largest data centre project is already built on exactly that flexibility.

Three days ago, writing about BlackRock’s $40 billion Aligned Data Centers deal, I referenced Zerra’s proposed Western Downs project as the Australian mirror of the same story: capital chasing grid access, not land or chips. At the time it was a $31.9 billion proposal with no anchor tenant. It now has one, and it’s the company whose AI platform is powering this analysis.

The size dwarfs everything else in the queue

AEMO’s own count has 5.4GW of data centre capacity working through the east coast transmission queue across 11 projects. Firmus has proposed 1000MW at Tailem Bend and 1300MW at Stirling North in South Australia, backed by a 600MW energy supply agreement. IREN has an 800MW deal tied to Bundey. None of these, added together, gets within range of a single $30 billion site. Western Downs isn’t part of the pipeline. It resets the scale of what the pipeline means.

Location was the deal term, and Crisafulli’s gas bet cashed in early

Fuel flexibility only mattered because Zerra picked a site that could use it. The 725 hectares near Dalby sit next to gas generation, solar and transmission that already exist, which is what let this project move at a normal construction timeline instead of sitting in the multi-year interconnection queues I wrote about in the Aligned piece. Anthropic still needs firmed, round-the-clock power for inference, and regulatory permission to use gas is only valuable next to gas plants that are already built.

That permission is the other half of this story. In late August, Crisafulli told reporters ahead of National Cabinet that Queensland would be “technology agnostic” on data centre power. Canberra initially resisted, but the outcome gave Queensland and the Northern Territory a pathway the rest of the country doesn’t have. Three weeks later, that pathway isn’t theoretical. Western Downs’s own development application has stage one running on gas or grid electricity, with renewable PPAs for wind, solar and storage layered on top rather than as the sole supply. That’s the win Crisafulli was arguing for, landing faster and bigger than his own numbers suggested.

The social license fight is the part he hasn’t won yet

Queensland residents have told state parliament they’re worried about water use, electricity draw and the loss of the area’s rural character. In Tasmania, Firmus is separately arguing in the state’s civil tribunal that a council’s limit on 276 backup diesel generators at its Bell Bay project is “unreasonable.” Western Downs plans to store 186,336 litres of diesel across 20 generators of its own. Crisafulli has won the energy argument. He hasn’t yet had to defend the generator fight that tends to come with it.

The question worth asking about Western Downs isn’t whether Queensland’s gas strategy can attract a $30 billion tenant. Anthropic just answered that emphatically. It’s whether the state can hold the social license for gas-backed, diesel-backstopped power at this scale through construction and 1,400 permanent jobs, or whether it inherits the same generator dispute Firmus is currently fighting in Tasmania.
