Telstra has launched the longest route in its next-generation Aura fibre network, establishing a high-capacity connection between Perth and Sydney as demand from cloud computing, artificial intelligence and data centres accelerates.
The new route forms part of Telstra’s wider A$1.8 billion investment in national digital infrastructure and connects Western Australia with major technology and data centre hubs on the east coast.
It also provides a link between eastern Australian markets and international subsea cables landing in Perth, strengthening Australia’s east-west digital corridor.
AI drives demand for capacity
AI is dramatically increasing the volume of information moving between data centres.
Training and operating large models requires vast quantities of data to be transferred between computing facilities, cloud platforms and customers, putting pressure on existing telecommunications networks.
Telstra’s Aura network has been designed to provide greater capacity, lower latency and additional redundancy across major intercity routes.
The Perth-Sydney connection is particularly significant because Western Australia is becoming increasingly important as a gateway to international markets through subsea cables connecting Australia with Asia, the Middle East and Europe.
The infrastructure also supports the rapid expansion of domestic data centres.
Billions of dollars are being committed to new Australian computing facilities, but the sector requires more than electricity, land and cooling systems.
High-capacity fibre connections are essential for moving information between those facilities.
That means Australia’s AI investment boom is increasingly flowing through to another layer of infrastructure: the telecommunications networks connecting the country’s growing computing capacity together.
