The Albo government waited until after the conclusion of APEC to let the public know that divers with the Royal Australian Navy suffered injuries after being attacked by sonic pulses from a communist Chinese warship. This attack occurred of the coast of Japan on November 14, before the PM Albo left to attend APEC. This was done in international waters. If the sides were reversed and Australia did this to the Chinese, I expect that it would be seen as an act of war. Wars have started for less.
As Malcolm Roberts rightly points out, it is about time our political leaders started protecting Australian interests, rather than bowing to communist China, in cringing, embarrassing acts of appeasement, which emperor Xi would simply laugh at.
