Australia and the United States have mutual interests and investments in the Pacific. Underlying this is a sense of shared cultural values and shared legacy as former British colonies.

To act as if the United States is sticking its nose in Australia as if it's Venezuela or something shows a rather pedestrian understanding of Australian history and geopolitics.

If the United States retreats from the world the Australian people will be among those who suffer the most. The interest in each other is mutual.

Edit: I'm not endorsing any particular intervention I'm merely pointing out the parent comment's framing (basically Australia should just ignore the United States or vice-versa) is silly given the reality of the relationship between the two countries, especially right now given how Australia views the present risks associated with the growing threat of Chinese hegemony in the Pacific.
