Australia's AI Infrastructure Moment: $100 Billion Bet on Sovereign Compute

Australia has become ground zero for Asia-Pacific AI infrastructure investment. OpenAI launched its "OpenAI for Countries" program with a $7 billion Sydney campus, marking the company's first major APAC initiative.¹ Amazon announced the largest technology investment in Australian history at $20 billion for AWS expansion.² Google quietly negotiated to build an AI data center on Christmas Island following a defense agreement.³ And Project Southgate aims to deploy 1.6 GW of NVIDIA-powered capacity across four Australian capitals.⁴

The convergence reflects a strategic shift: major AI companies now view sovereign compute capability—infrastructure that keeps sensitive data within national borders—as essential infrastructure for government, defense, and enterprise customers. Australia's positioning as a stable democracy with strong institutions, favorable geography, and growing renewable energy capacity makes it the natural hub for APAC sovereign AI workloads.

The OpenAI for Australia Initiative

OpenAI signed a Memorandum of Understanding with NEXTDC in December 2025 to develop Australia's first sovereign AI infrastructure partnership.⁵ The collaboration centers on NEXTDC's S7 site in Eastern Creek, Western Sydney, where the companies will develop a next-generation hyperscale AI campus and large-scale GPU supercluster.⁶

Location	Eastern Creek, Western Sydney
Capacity	650 MW (upgraded from initial 550 MW)
Phase 1	H2 2027
Status	Pending approvals

The 650 MW capacity would surpass CDC's recently approved 504 MW site, making S7 potentially the most powerful data center in the Southern Hemisphere.⁷ NEXTDC CEO Craig Scroggie characterized the facility as an "AI factory" that will establish Australia's position in global AI infrastructure.⁸

OpenAI for Countries Framework

The Australia partnership represents OpenAI's expansion of its national infrastructure program to the Asia-Pacific region.⁹ The "OpenAI for Countries" model addresses critical concerns that limit AI adoption in government and enterprise sectors:

Data Sovereignty: Sensitive workloads remain within Australian borders, satisfying regulatory requirements for government, defense, and financial services data.¹⁰

Latency Optimization: Local inference reduces round-trip times for Australian users compared to routing through US or Asian data centers.¹¹

National Security: Sovereign compute enables AI applications for defense and intelligence that cannot be hosted on shared international infrastructure.¹²

Economic Development: Local AI infrastructure drives investment, employment, and technology transfer.¹³

Target Workloads

The S7 facility will serve mission-critical applications across sectors:¹⁴

Sector	Applications
Government	Federal and state agency AI deployments
Defense	Australian Department of Defence applications
Finance	Banking, insurance, trading systems
Research	Academic and scientific computing

The Christmas Island Project

Google's planned data center on Christmas Island represents the most strategically significant AI infrastructure project in Australian territory.

Defense Connection

In July 2025, Australia's Department of Defence entered a three-year cloud computing agreement with Google.²² Shortly after, Google began negotiating to build an AI data center on Christmas Island, Australia's remote territory in the Indian Ocean approximately 350 kilometers south of Indonesia.²³

Facility Specifications

Aspect	Details
Location	Near airport, Christmas Island
Initial capacity	7 MW
Power source	Diesel and renewables
Connectivity	New subsea cable to Darwin
Status	Environmental approvals pending

In October 2025, Google applied for Australian environmental approvals to build the first subsea cable connecting Christmas Island and Darwin, a city where US Marine Corps are based for half of each year.²⁴

Strategic Implications

The location offers significant military intelligence value. Christmas Island provides optimal positioning for monitoring naval activity through critical maritime chokepoints:²⁵

• Sunda Strait
• Lombok Strait
• Malacca Straits

Retired Navy Commodore Peter Leavy explained: "Christmas Island is quite well positioned to at least monitor what is going through Sunda Strait, Lombok Strait, Malacca Straits. It is a really good location."²⁶

Bryan Clark, a former US Navy strategist, noted that a forward data node could support AI-enabled command-and-control activities, including management of uncrewed systems.²⁷ The subsea cable ensures bandwidth and reliability superior to satellite connections, which could be targeted during crises.²⁸

Google's Official Position

Google officially downplayed the project's scope: "We are not constructing 'a large artificial intelligence data center' on Christmas Island. This is a continuation of our Australia Connect work to deliver subsea cable infrastructure."²⁹

The careful phrasing—denying construction of a "large" facility while not denying any data center construction—leaves room for the modest 7 MW facility reported in negotiations.³⁰
