On Wednesday, US President Joe Biden, Australian Prime Minister Scott Morrison, and his UK counterpart Boris Johnson unveiled the AUKUS security alliance "to protect and defend" the three countries' "shared interests in the Indo-Pacific".

Washington and Canberra have agreed on bolstering bilateral military collaboration that will include the "rotational deployment" of all types of American warplanes to Australia.

The move comes a day after the two countries along with the UK announced the creation of the so-called AUKUS defence alliance, which, in particular, stipulates arming Australia with a nuclear-powered submarine fleet.
