Key Points
US downgrades AUKUS offer to three secondhand submarines, saving Australia money on maintenance and training.
Greens warn nuclear submarines risk drawing Australia into US-China conflict and threaten sovereignty.
PM Albanese insists AUKUS continues full speed ahead despite renewed political opposition.
Labor backbenchers Ed Husic and Peter Garrett join criticism, questioning whether Australia should defend distant sea lanes.
Australia’s $368 billion AUKUS nuclear submarine agreement faces fresh political pressure after the US amended its offer to provide three secondhand Virginia-class submarines rather than a mix of used and new vessels. The Greens and Labor backbenchers are now questioning whether the deal risks Australian sovereignty and draws the nation into a potential conflict with China. Prime Minister Anthony Albanese insists the program continues “full steam ahead.”
Why the Deal Changed
The US shifted its offer to provide three in-service Virginia-class submarines instead of the original plan for two used and one new boat. The government says this saves money on acquisition, maintenance, and training costs. The change has reignited scrutiny over the multi-decade agreement, which was signed to deepen military ties between Australia, the United States, and the United Kingdom.
Opposition Arguments Against the Submarines
Greens defence spokesman David Shoebridge warned the deal risks war with China and said Australia would become an “interoperable” part of the US military. He argued Australia is too small to defend distant sea lanes like the Strait of Malacca and should focus on defending its own borders with conventional submarines. Labor backbencher Ed Husic and former minister Peter Garrett have also criticised the agreement, saying Australia should not be drawn into “someone else’s knife fight.”
Government’s Defence of the Program
Prime Minister Albanese told reporters the submarines make sense for an island continent and are beneficial both economically and strategically. Defence Minister Richard Marles has said nuclear-powered submarines are needed to protect Australia’s sea trade and project force across the region. Critics say the government is losing sovereignty to Washington through the revised deal, but officials maintain the program remains on track.
What Comes Next
Shoebridge said there remains a window for Australia to abandon AUKUS and buy conventional submarines instead. However, with the US having downgraded the deal to secondhand vessels, Australia’s options to exit have narrowed significantly. The debate reflects broader tension over how Australia should balance its relationship with the US against regional concerns about China.
Final Thoughts
Australia’s $368 billion AUKUS submarine deal faces political headwinds over sovereignty and war risks, but PM Albanese remains committed to the program. Opposition pressure is unlikely to derail the agreement, though debate over Australia’s defence strategy will persist.
FAQs
The US switched to three secondhand Virginia-class submarines to reduce Australia’s acquisition, maintenance, and training costs versus the original mixed vessel proposal.
