One further comment after a bit of reflection.
Another big reason Australia would never choose China over the US is that the US treats Australia as an equal. China never would. We’ve done our time as colonies. We’re not going back to that.
The bottom lines is in the headline ‘China Warns Australia - Choose Between us or the United States’.
The United States would never demand we make a choice like that. If we chose to cut ties with America, then America would accept that (unless we somehow became a threat to America or Americans). We have a voluntary relationship with the US based on mutual advantage, support, and respect. That’s the only type of relationship with another nation we want.
I find that a little airey-fairey. Take it for what it's worth, but my view is that the seeds of Albion will always hang together, bound as they are by ties of blood, culture and language. I believe the ABCA group is way more tightly-bound than NATO even though it's not a formal alliance.
