A landmark half-century defence pact between the UK and Australia is set to be formalised during high-level ministerial talks in Sydney.
Foreign Secretary David Lammy and Defence Secretary John Healey are meeting their Australian counterparts and Prime Minister Anthony Albanese at the yearly Aukmin summit today.
The treaty, spanning five decades, will establish the framework for bilateral cooperation under the Aukus defence alliance.
Following the Sydney discussions, both ministers plan to travel to Melbourne on Saturday for meetings with firms participating in the submarine construction initiative, before heading to Darwin where Royal Navy vessels are arriving.
The Aukus alliance, established in 2021 amongst Britain, America and Australia, centres on developing nuclear-powered attack submarines and broader defence collaboration.
Australia will acquire its first nuclear submarine fleet through the programme.
However, the Trump administration has placed the partnership under review, prompting concerns about potential American withdrawal.
Defence Secretary John Healey emphasised Britain's unwavering support, saying: "Britain's commitment to Australia was 'absolute'."
