Australia and the UK will sign a 50-year treaty to cement the Aukus submarine pact, even as the major partner in the Aukus agreement, the US, wavers on the deal.
The new treaty will be announced by the foreign affairs minister, Penny Wong, and the defence minister, Richard Marles – alongside the British foreign and defence secretaries, David Lammy and John Healey – after the annual Aukmin talks in Sydney on Friday.
