Australian carrier Telstra has launched the Perth-Sydney route of its Aura Network.

The route is the longest within the network that links Australia's east-west digital corridor and connects major cloud, data center, and business hubs of Australia's eastern states to Perth, into the western global subsea cable networks.

Aura Network, originally known as the Intercity Fibre Network, is a high-capacity city-to-city fiber system that is set to span 14,000km (8,699 miles).

It is set to link Perth, Sydney, Adelaide, Melbourne, Canberra, Darwin, and Brisbane. The Sydney to Melbourne coastal route launched in October 2025.

To date, 9,000km (5,592 miles) of this planned build have been built, with active routes across Sydney, Melbourne and Canberra. According to Telstra, it is designed to provide up to 35 times more fiber capacity per path and greater resilience than conventional fiber routes.

Steven Worrall, CEO, Telstra Digital Infrastructure, highlighted the importance of the latest Perth-Sydney route, noting the automated mining and industrial operations in Western Australia.

“As these industries become increasingly data-driven, the connectivity linking them to customers, partners, cloud and compute is becoming just as important as the technology deployed on the ground," said Worrall.

“The Perth-Sydney route adds another high-capacity pathway between Australia's west and east, helping businesses move data more reliably across the country and strengthening the connections between WA's growing digital economy and global markets.

The latest route is part of Telstra's wider AU$1.8 billion (US$1.25bn) investment into building Australia's digital infrastructure.
