Malcolm Turnbull, who was behind the French submarine contract that Morrison dramatically tore up in favour of Aukus, said Australia needs to "wake up", realise it's a "bad deal" which the US could renege on at any point, and make other plans before it is too late.

LONDON (Reuters) -Britain said on Thursday it understood a decision by U.S. President Donald Trump's administration to launch a formal review into the AUKUS submarine pact, repeating London's position that the project was crucial to peace and security.

Congressional Democrats condemned the review as casting doubt over the strength of America's alliances with Britain and Australia.
