Is Anthropic building Australia’s largest data centre?

Green Street News reported on 11 June 2026 that Anthropic is courting developers and operators to deliver the largest digital infrastructure facility in Australia. The report names no capacity, site or operator, and Certified Strategic has not independently verified those specifics. Anthropic has not announced a facility or a capex figure. The report is consistent with Anthropic’s disclosed move to lease and operate its own Australian capacity, and with its Sydney hiring, which now spans six live data centre roles including a dedicated energy lead.

How large would a facility need to be to be Australia’s largest?

It would need to exceed the projects already in the pipeline. AirTrunk’s proposed SYD4 campus at Kemps Creek is planned at 1.2GW and would be the first Australian data centre to pass 1GW. CDC’s Marsden Park campus is 504MW, described on approval as the largest in the southern hemisphere, and NEXTDC’s OpenAI-anchored Western Sydney facility sits near 550MW. A facility marketed as Australia’s largest therefore implies gigawatt-scale capacity.

Which Australian operators could land an Anthropic facility?

NEXTDC, AirTrunk and CDC Data Centres are the three operators Anthropic met during its April 2026 National AI Plan visit. NEXTDC anchors the largest disclosed AI-lab tenancy in Australia through OpenAI. AirTrunk operates the highest-capacity proposed campus at 1.2GW SYD4. CDC holds Hosting Certification Framework Strategic-tier status for Commonwealth and regulated workloads. A multi-operator approach, matching Anthropic’s United States model, is also consistent with its hiring.

Anthropic courts developers to build Australia’s largest data centre as its Sydney roster doubles

At a glance

Green Street News reported on 11 June 2026 that Anthropic is courting developers and operators to deliver what would be the largest data centre in Australia.
Anthropic’s Sydney data centre roster has grown from three roles to six in a fortnight. All six are live on its Greenhouse board as of 11 June 2026, inside the Compute organisation.
The newest of the six is a Data Center Energy Lead, Australia, briefed to secure multi-hundred megawatt power capacity and structure power purchase agreements across the National Electricity Market, the Wholesale Electricity Market and the Northern Territory Electricity Market.
To be Australia’s largest, any Anthropic facility would have to clear AirTrunk’s proposed 1.2GW SYD4 campus at Kemps Creek, the largest data centre yet proposed in the country.
The procurement lands in a grid that AEMO now forecasts will carry 12.0TWh of data centre load by 2030, and where connection requests already outstrip deliverable supply across New South Wales and Victoria.

What Green Street reported

Green Street News reported on 11 June 2026, under the byline of Nelson Yap, that Anthropic “is courting developers and operators to deliver the largest digital infrastructure facility Down Under.” The report is behind Green Street’s Australia subscription, and the published summary carries no capacity figure, no named site and no named operator. Certified Strategic has not independently confirmed those details.

In a post promoting the report, Yap framed the proposed facility as positioning Australia as a global digital infrastructure hub, at a scale he described as rivalling Snowy 2.0, the nation’s largest renewable energy project, in cost, and exceeding the combined value of Australia’s most expensive office towers. Snowy 2.0 was officially budgeted near A$12 billion before well-documented overruns. Those comparisons are the reporter’s characterisation of scale rather than disclosed figures, and the capacity and capital numbers behind the search remain unpublished.

The claim is consistent with Anthropic’s disclosed posture. Data Center Dynamics reported on 20 April 2026 that Anthropic was seeking data centre leasing deals in Australia and Europe and building an internal data centre team after years of buying compute through cloud providers. In April, Anthropic met the chief executives of NEXTDC, AirTrunk and CDC Data Centres alongside the signing of its National AI Plan memorandum of understanding. What the Green Street report adds is scale: a search framed around the largest facility in the country, rather than incremental capacity through a third-party cloud.

The evidence in Anthropic’s Sydney hiring

The signal Certified Strategic can verify directly sits on Anthropic’s careers board. As we reported on 18 May, Anthropic posted its first three Sydney data centre operations roles in mid-May. Three more have gone live since. All six are open on Anthropic’s Greenhouse board as of 11 June 2026, inside the Compute organisation.

The roster now runs from commercial delivery through live operations, building engineering and power. The Sydney Transaction Principal that sourced sites has closed since the last refresh, while the other six roles remain live. As we set out on 18 May, Sydney carries Anthropic’s deepest data centre operations footprint outside the United States. On the company’s careers board as of 11 June 2026, the facility, hardware and capacity delivery leads, now joined by the energy lead, are listed in Sydney and no other office in the Asia Pacific or Europe. Tokyo lists a data centre electrical engineer and a transaction principal.

The Energy Lead role is the one that maps to a gigawatt-scale ambition. The job description tasks it with securing power capacity “for our rapidly expanding AI compute footprint across the region,” leading “multi-hundred megawatt procurement efforts” and building relationships with transmission and distribution network operators and regulators across multiple Australian jurisdictions. It calls for 15 or more years in energy procurement, experience securing 100MW or more of capacity, and expertise across the National Electricity Market, the Wholesale Electricity Market and the Northern Territory Electricity Market, including power purchase agreements and connection-queue strategy.

What Australia’s largest data centre looks like today

For an Anthropic facility to be the largest in Australia, it would have to clear the projects already in the national pipeline. The current benchmark is set by three campuses.

Facility	Operator	Capacity	Investment	Status
SYD4, Kemps Creek (Mamre Road)	AirTrunk	1.2GW	A$5 billion plus	State Significant Development assessment
Western Sydney hyperscale AI facility	NEXTDC	~550MW	~A$7 billion	OpenAI anchor customer
Marsden Park campus	CDC Data Centres	504MW (scalable to 1GW)	A$3.1 billion	Approved Nov 2025

AirTrunk’s SYD4 at Kemps Creek, on the IFM Investors-owned Summit site, would be the first Australian data centre to pass the 1GW mark, at a planned 1.2GW. CDC’s 504MW Marsden Park campus was described on approval as the largest in the southern hemisphere, and NEXTDC’s Western Sydney AI facility, anchored by OpenAI, sits near 550MW. A facility marketed as Australia’s largest therefore implies the gigawatt class, which is the scale that makes the energy lead’s multi-hundred megawatt procurement brief read as a floor rather than a ceiling.

The grid any gigawatt-scale build has to navigate

A gigawatt-scale facility lands in a grid that now counts data centres as a category of their own. AEMO’s July 2025 data centre energy demand report put data centre consumption at 3.9TWh in the 2025 financial year, around 2% of National Electricity Market grid-supplied demand, and forecast growth of 25.1% a year to 12.0TWh by 2030, near 6% of the NEM. AEMO logged 44GW of data centre connection requests in its 2025 planning inputs against roughly 6GW of prospective capacity its central scenario requires.

New South Wales has logged more than 10GW of data centre connection requests over 18 months, more than half the state’s peak demand, per submissions to its parliamentary inquiry. Victoria’s AusNet has reported more than 8GW of load enquiries. The AEMC has proposed new connection standards for large data centres, raising the threshold for stricter technical requirements from 5MW to 30MW and adding ride-through obligations, with submissions closed on 7 May 2026 and a final rule expected mid-2026.

What it means for NEXTDC, AirTrunk and CDC

NEXTDC, AirTrunk and CDC Data Centres are the three operators named in Anthropic’s April meeting record, and each is the kind of partner a gigawatt-scale search would test. NEXTDC carries the largest disclosed AI-lab tenancy in Australia, with OpenAI anchoring its Western Sydney facility. AirTrunk operates the highest-capacity proposed campus in the country at SYD4 and is itself hiring a Senior Manager, Renewable and Carbon Procurement in Melbourne to source renewable PPAs. CDC Data Centres holds Hosting Certification Framework Strategic-tier accreditation and is recruiting a utilities services manager to lead grid connections across its Victorian portfolio.

Both sides of the table are staffing the utility-interface function at once. The capacity conversation between Anthropic and an Australian developer now seats power-procurement specialists on each side alongside the commercial and leasing teams.
