Telstra launches Perth-Sydney fibre route, the longest in its Aura Network
Telstra has switched on the Perth-Sydney route of its Aura fibre network, its longest leg, with 9,000km of a planned 14,000km now built. WA operators placing AI and cloud workloads now have a second east-west path to bring into this quarter's capacity and redundancy reviews.

What happened
- The same research credits Aura's committed Perth-Sydney and Perth-Adelaide routes with supporting about $3.7 billion of WA gross state product and 10,500 jobs by FY40.
- Those estimates rise to about $6.4 billion and 18,500 jobs only if a potential Darwin-Perth route goes ahead.
- Telstra counts the route as part of a broader $1.8 billion investment that includes network expansion in the Pilbara.

Why it matters
- constraint The route runs on Telstra's own network, so an operator whose primary east-west link is already Telstra's gains a path but not a second carrier.
- exposure Planners who budget against the $89.1 billion figure are adopting, as their base case, the accelerated scenario of a study Telstra commissioned.
- precedent With a minister already citing 10,500 jobs as a given, FY40 results will be judged against a figure the research only says the network could support.
- capability East-coast businesses get another Telstra land path to Perth's subsea cable links and the overseas data and compute platforms those cables reach.
To decide where AI or cloud workloads should run, an operator needs four figures from any new link: capacity, latency, physical path and price. Telstra's release says the route offers "greater capacity, resilience and speed" [4]. It also says the route will help WA organisations reach computing infrastructure and meet demand for AI and cloud [3]. The release does not include any of the four figures. Steven Worrall, chief executive of Telstra Digital Infrastructure, spoke about the WA businesses already on the network: "Now, with access to the Aura Network, these organisations can build on that momentum, improving connectivity with customers and partners across Australia, unlocking more growth, innovation and investment in WA." [8]
A skeptic would say the launch is a press release and the economics come from a study Telstra paid for. On the economics, the skeptic has a point. Oxford Economics produced the $89.1 billion figure for Telstra under an accelerated digital adoption scenario [11]. Getting there from $16.8 billion in FY25 takes growth of about 11.8% a year, compounded for fifteen years [15]. The route is different. It is live [1], and an operator can test what it is worth with a quote and a service specification this quarter.
Officials are already quoting the job estimate without the study's hedge. The research says the committed routes "could support" around 10,500 jobs by FY40 [12]. Patrick Gorman, Assistant Minister to the Prime Minister and Member for Perth, said: "This is a major investment for Australia and in Western Australian workers. Supporting 10,500 jobs by 2040." [14] The study's larger estimate adds 8,000 jobs and $2.7 billion of gross state product, and those depend on a Darwin-Perth route the release still calls potential [13][16].
The rest of the network will take longer. About 64% of the planned length is built, and 5,000km is still to come [9][10]. The leg that went live this week is one route. The GSP and jobs figures are outcomes for FY40 [12]. For a WA operator, this quarter's choice is whether to add Perth-Sydney to capacity and redundancy reviews as a candidate path and ask Telstra for its specifications. I think that is justified now. Rebuilding the redundancy plan around the route should wait until the path and capacity figures are on paper, because next quarter's commitments to east-coast cloud regions will depend on them.
What to watch
- Whether Telstra publishes capacity, latency or wholesale pricing for the Perth-Sydney route, the figures a WA redundancy design would need.
- Whether the potential Darwin-Perth route becomes a committed one, the condition for the study's 18,500-jobs estimate.
- Progress on the remaining 5,000km of the planned network, including when the committed Perth-Adelaide route goes live.
