The Australian naval base HMAS Stirling, the future hub of the AUKUS network, is about to be quietly connected to three new high-capacity submarine internet cables, built by Google (Alphabet) and the operator SUBCO, according to documents obtained by Reuters. These new links, which will connect Australia to Africa, Asia, and the Indian Ocean, will place the base at the heart of a rapidly expanding strategic digital network.
From 2027, HMAS Stirling will host four American nuclear attack submarines on a rotational basis. Virginia and a British submarine. This increased presence of US forces at the entrance to the Indian Ocean is part of a broader effort to strengthen the monitoring of Chinese underwater activities. The new digital infrastructure is designed to enhance the resilience of military communications and support Australia's ambitions in artificial intelligence.
SUBCO has confirmed that a new cable linking Australia's east and west coasts will include a direct branch to HMAS Stirling, although public documents only mention a landing at Perth. Google also plans two transoceanic cables, one to Christmas Island, Australia's strategic outpost in the Indian Ocean, and the other to Africa, both arriving in the immediate vicinity of the base.
These projects are part of a broader trend: the proliferation of submarine cables to secure the Indo-Pacific region. Google itself acknowledges in its environmental documents that "geostrategic changes" influence its infrastructure choices.
For Canberra, connectivity has become a matter of national security. The American forces, with more than 1,000 personnel expected next year, will need a robust and redundant network; for their part, the Australian authorities point out that cables are both a vital resource and a major vulnerability, as acts of sabotage increase worldwide.
These new underwater routes would therefore improve the country's resilience, while strengthening technological integration among AUKUS allies. The projects are, however, subject to strict environmental assessments, particularly concerning endangered marine species, but Google assures it intends to comply with all requirements.
According to experts, the whole could transform the western Australian coastline into a true strategic data hub, essential for future autonomous operations, long-range drones and AI systems shared between allies.
