Depends what you mean. Our government has a very long standing relationship with the US, and it would probably be difficult to extricate ourselves from that in any meaningful way in the short term. Whether or not individual people have a choice - not really. I expect the majority of Australian's welcome the (perhaps illusionary) security afforded by our relationship with the US.

China has been at least a consumer of Australian produce if not an "ally", but they've shown a willingness to bully us economically over minor political disagreements. If a military relationship is a gateway to any sort of economic relationship with the US then it's probably a good thing. They already gave us submarine tech which will provide us some economic benefits as we manufacture them and sell to our allies.
