Australia and Britain have signed a new defence and security agreement that facilitates easier cooperation between their defence forces in each other's countries. The agreement was signed during talks in Adelaide between British Foreign Secretary David Cameron, Defence Secretary Grant Shapps, and their Australian counterparts. The treaty requires the nations to consult each other in the event of a threat. Under the AUKUS agreement, Australia has chosen BAE Systems to assist in building new nuclear submarines, marking a significant development in Australia's defence capabilities.
