Why Christmas Island is Google’s Next AI Data Centre Home

Remote island territories are emerging as unexpected locations for AI infrastructure that serves both commercial cloud services and defence intelligence operations. 

This convergence is influencing where tech companies build AI data centres, with strategic geography today weighing as heavily as traditional factors like energy costs and connectivity.

Now, Australia’s Christmas Island, better known for its annual red crab migration than cutting-edge technology, is preparing to host a Google AI data centre.

The bigger picture

The announcement follows a cloud agreement between Google and Australia’s Department of Defence signed in early 2025. 

Military experts claim that a data centre on the island would provide capability for monitoring naval activity in the Indian Ocean, with defence officials viewing the facility as infrastructure for frontline surveillance operations. 

Google is in talks to rent land near the island’s airport to construct the site and negotiate with a local mining company to support energy requirements.

Bryan Clark, a former US Navy strategist, tells Reuters: “The data centre is partly to allow you to do the kinds of AI-enabled command and control that you need to do in the future, especially if you rely on uncrewed systems for surveillance missions and targeting missions and even engagements.

“If you’ve got a data centre on Christmas, you can do a lot of that through cloud infrastructure.”

Defence departments expanding Google cloud partnerships across regions

In July 2025, Australia’s defence department entered a three-year cloud agreement with Google. 

Britain’s military announced a similar deal to enhance intelligence sharing with the US.

These agreements show how defence organisations are shifting classified workloads to commercial cloud providers rather than building dedicated military systems from scratch.

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

The cable would provide the high-bandwidth, low-latency connections that modern data centres require to function as part of global cloud infrastructure.

Christmas Island has historically struggled with poor telecommunications and limited job opportunities. 

The island gained international recognition for its spectacular red crab migrations from rainforest to coast, but economic development has remained constrained by geographic isolation.

Steve Pereira, Shire President of Christmas Island, says his administration is examining what impact the data centre will have on the local community. 

He says: “There is support for it, providing this data centre actually does put back into the community with infrastructure, employment and adding economic value to the island.

“There are many industries on the island we have to protect, all of this will be closely considered for any new projects - whether it be defence or Google.”

How the Indian Ocean offers commercial and military advantages

Two sources from Christmas Island and one from the defence sector indicate the data centre offers commercial advantages for Google due to its strategic Indian Ocean location between Africa, Asia and Australia, alongside potential military applications. 

The island’s position provides geographic proximity to major shipping routes through the Sunda Strait, Lombok Strait and Malacca Straits.

The facility would support AI-enabled command and control systems that process data from autonomous surveillance platforms. 

These systems need low-latency access to computing infrastructure to analyse sensor data and coordinate operations in real time. 

Routing this data to distant cloud regions introduces delays that can compromise mission effectiveness.

In September 2025, Google announced a new AI data centre in the UK as part of a £5bn (US$6.82bn) investment programme. 

Demis Hassabis, Co-founder and CEO at Google DeepMind, says at the time: “We founded DeepMind in London because we knew the UK had the potential and talent to be a global hub for pioneering AI.”

Retired Navy Commodore Peter Leavy tells Reuters: “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.”
