Greens warn nuclear submarines deal risks war with China as Albanese says Aukus ‘full-steam ahead’

David Shoebridge says Australia could become embroiled in a US war with China if purchase of Virginia-class attack submarines proceeds

Anthony Albanese has reiterated that Aukus is “full-steam ahead” after the Greens renewed calls to cancel the nuclear-powered submarines deal, which the minor party warned could draw Australia into a potential US war with China.

Debate over the security pact has resurfaced after the announcement that Australia would buy secondhand Virginia-class submarines from the US, rather than a mix of old and new vessels.

The Greens have seized on the development to re-prosecute the case for the government to abandon the multi-decade, $368bn agreement.

Appearing on ABC’s Insiders program on Sunday, the Greens’ defence spokesperson, David Shoebridge, said the focus of Australia’s military assets should be on defending the nation’s borders.

He suggested that could be done with conventional submarines and other weapons, rejecting the need for capabilities designed to operate “thousands of thousands of kilometres from our shore” – such as the nuclear-powered vessels.

Shoebridge said buying the Virginia-class submarines would make Australia an “interoperable” part of the US military, drawing the country into a potential conflict with China.

“Nuclear submarines are pretty much a disaster on every front,” he said.

“Why are we inviting ourselves to a US war with China by buying this weapons platforms and making our defence an interoperable part of the US?”

Shoebridge said the greatest strategic threat facing the country was not China’s military buildup or disruptions to key shipping lanes.

Rather, it was the risk of Canberra losing its sovereignty to Washington, as he said occurred with the revised deal to send three secondhand submarines to Australia.

The government this week insisted it was always its preference to buy so-called “in-service” Virginia-class submarines from the US, saving money on acquisition, maintenance and training costs.

Shoebridge said there was a still a window of opportunity for Australia to dump Aukus and buy conventionally armed submarines from countries such as Japan, South Korea or Sweden without leaving a capability cap after the retirement of the Collins-class vessels.

He claimed the US was the world’s least-reliable supplier of submarines given the slow rate of production from its shipyards.

Shoebridge’s suggestion that Australia could acquire a different class of submarine appears to jar with the Greens’ own defence policy, which proposes to axe “unstrategic projects” including the Collins-class program.

Albanese brushed off Shoebridge’s criticisms when asked about them later on Sunday, declaring Aukus was “full-steam ahead”.

“We won’t be taking advice on defence from the Greens political party with respect,” the prime minister said at a press conference in Caloundra on the Queensland Sunshine Coast.

“What we’ll be doing is providing Australia with the defence assets that we need. Our alliance with the US is an important one but we promote peace and security in our region and the relationship with China is a very constructive one.”

The Aukus agreement – which also includes the UK – is expected to be on the agenda when the defence minister, Richard Marles, and the foreign affairs minister, Penny Wong, hold talks with their British counterparts next week.

Marles and Wong are scheduled to meet with the UK defence secretary, John Healey, and the UK foreign secretary, Yvette Cooper on Wednesday as part of a round of talks in Britain and Europe.

The Australian ministers will also sit down with their German counterparts for the first meeting of its kind since 2021.

Wong will also meet the French foreign affairs minister in Paris and Marles will hold talks with his Finnish counterpart during the trip.

“While geographically distant, Australia and Europe’s interests are increasingly interconnected which is why we must focus our partnerships on reinforcing collective deterrence,” Marles said.

“In complex and uncertain times, the United Kingdom remains a critical partner for Australia and we continue to strengthen and modernise our partnership including through the Aukus partnership.”
