Google, SUBCO Cables Converge at Australia's AUKUS Submarine Base
13 Nov
Summary
- New undersea internet cables planned by Google and SUBCO to connect Australia's coasts and regions
- Cables to land near HMAS Stirling naval base, home of U.S. Virginia submarines from 2027
- Cables seen as critical for Australia's military digital resilience and AI ambitions
As of November 13, 2025, Australia's AUKUS submarine fleet base and its vicinity are quietly being connected to three powerful new undersea internet cables planned by Alphabet's Google and local company SUBCO. The HMAS Stirling naval base on Australia's west coast will house four U.S.-commanded Virginia submarines from 2027, placing the U.S. Navy on the Indian Ocean's rim as Washington and Canberra step up surveillance of Chinese submarine activity.
The superfast cables being built by Google and SUBCO will span the Indian Ocean to Africa and Asia, and connect Australia's east and west coasts, with landing points near HMAS Stirling. This places the base at the center of a rapidly expanding network as Australia seeks to bolster its digital resilience for military purposes. SUBCO says a new high-capacity cable connecting Australia's coasts will include a branch to HMAS Stirling, while Google's plans include cables to Australia's Christmas Island and across the Indian Ocean to Africa.
Experts say militaries need high-speed data connectivity between installations and allies, and the new cables will provide better resilience against incidents of cable sabotage globally.
