Google and Telstra on Tuesday announced a landmark infrastructure partnership that merges terrestrial fibre and subsea cable capacity across Australia and the Asia-Pacific region, marking one of the most significant digital infrastructure deals in the region as artificial intelligence (AI) workloads drive surging demand for high-capacity connectivity.
The partnership was jointly announced by Bikash Koley, Vice President of Global Infrastructure at Google, and Steven Worrall, Chief Executive Officer of Telstra Digital Infrastructure.
Under the agreement, Google will secure inter-city dark fibre capacity on Telstra’s Aura Network, while Telstra gains access to fibre pairs on Google’s Tabua, Proa and Bulikula subsea cable systems through Google’s Pacific Connect and Australia Connect initiatives. Those cables connect Australia to Japan, the Pacific Islands and the United States.
The deal is structured as a mutual capacity exchange rather than a conventional commercial transaction, with each party gaining access to infrastructure the other has built. The Aura Network represents a USD 1.6 billion investment spanning over 2,205 kilometres of new fibre and offers 35 times the capacity of legacy routes, delivering up to 83.6 terabits per second on dark fibre.
More than 8,000 kilometres of the Aura Network have already been laid across Australia, including new coastal routes linking Melbourne, Canberra and Sydney, with the full rollout projected to reach 14,000 kilometres on completion.
Both companies say the core strategic benefit is resilience. By combining terrestrial and subsea pathways, they eliminate single points of failure and create redundant routing for enterprise, cloud and AI traffic that previously relied on more limited network paths.
The three subsea cable systems involved are all set to come online before the end of 2026, giving Telstra more diverse and secure international pathways at precisely the moment AI-driven data flows are accelerating across the Pacific.
Worrall framed the deal in national strategic terms. “The partnership is about enhancing our national capability and ensuring that Australia remains seamlessly connected to the global economy,” he said.
Both parties stated that as AI applications and workloads continue to grow rapidly, the underlying infrastructure must evolve to securely and reliably support data flows not only within Australia but also across key international corridors.
