I wouldn’t be quite that bullish.

Yes Aus in particular is a lapdog for the US and has been for decades, NZ are our weaker smaller brother in that same dynamic.

But China has their hooks in to Aus in a way that we can’t unshackle now, not without massive changes that no-one in their country is prepared for.

If the choice is between changing to China / BRICS+ or sticking with The West and the dollar and US security it’s obvious the latter is preferred but I could see a situation where we flip.

If we had to call the US bluff on invasion of Australia for example (ie they want to false flag us to get Aus aligned in war) I could see that being a line to switch allegiances for example.
