Google is laying new submarine cables along Australia’s northern and western approaches. The routes will link to a planned Google AI data centre on Christmas Island, likely building on an existing cloud deal with the Australian Department of Defence. The cables also connect to naval base HMAS Stirling, 35 kilometres south-west of Perth, which will host AUKUS partners and nuclear-powered submarines. Together, these moves reflect a shift in Defence planning as senior officials warn that the regional security environment is worsening. Australia’s Chief of Navy Mark Hammond described seabed cables at an address last month as “our lifelines”, noting that their loss would pose “an existential threat to our island and to our people”. His assessment reflects a growing recognition that the integrity of these cables underpins Australia’s economy, military networks and connections to the world.
