Historically speaking, the US might even be a larger risk to Australia than China is. The US alliance goes back a long way, and so does the opposition to US influence. Since the Whitlam government, MPs are generally fearful of US retaliation, rendering much of our politics hostage to US influence. Of course, some PMs have openly embraced the US so this feeling isn't universal. But many of our issues are directly tied to the US.

China has been far more beneficial to Australia by comparison, with the downside being the encroaching influence of CCP propaganda. Many of our strengths are tied to our relationships with Southeast Asia.

Paul Keating has famously declared US as an "aggressive ally", "our colonial masters", AUKUS as our "worst international decision", and that "our future is in Southeast Asia". This was under Biden too.

So the situation is much more complicated, and the feelings on the ground right now is that the US are not our friends (of course, the CCP is not great either).

You don't even need to step foot on US soil for the US to be a risk to you
