I don't this this is a symmetric relationship. Since Trump can't into office, the US has taken an extremely aggressive stance towards China and has sought to intensify the conflict over a whole range of areas (initiating the trade war, making wild accusations of genocide, moving towards recognition of Taiwan, pushing conspiracy theories about CoVID-19), while China has tried to avoid escalation and has almost never gone beyond reciprocal actions. Australia has aligned itself fully with the US in most of these actions, leading the charge against Huawei, funding a prominent think tank that churns out anti-Chinese propaganda, pushing the lab-leak conspiracy theory, inserting itself into disputes in the South China Sea, etc. I think there's a clear aggressor in this situation. The US believes that China is a threat to the unipolar order that has prevailed since the dissolution of the Soviet Union, and has embarked on a confrontational policy towards China. Australia, caught between its military ally and its top economic partner, has decided to throw itself entirely behind its military ally.
