In the long term, an estimated A$30b is expected to be spent on the facility.
“The transformation underway at Osborne shows Australia is on track to deliver the sovereign capability to build our nuclear-powered submarines for decades to come,” he said.
The investment in the Submarine Construction Yard “is critical to delivering Australia’s conventionally armed, nuclear-powered submarines”, Prime Minister Anthony Albanese said in a statement.
“We are accelerating Aukus opportunities to secure Australia’s future defence capability and create lasting prosperity and jobs for the state,” he added.
In September, Canberra also revealed a US$8b investment to be spent over a decade to transform a shipbuilding and maintenance precinct in Perth, Western Australia, into facilities for a future fleet of nuclear-powered submarines.
Australia had a major bust-up with France in 2021 when it cancelled a multi-billion-dollar deal to buy a fleet of diesel-powered submarines from Paris and went with the Aukus programme instead.
The pact was thrown into doubt last June when Washington said it was launching a review into whether it aligned with US President Donald Trump’s “America First” agenda.
In December, the Pentagon said it had cleared that hurdle and that Trump had ordered it “full steam ahead”.
