By your description, Australia badly needs some kind of colonial overlord to keep it in check. Australia, as you lay it out, is due the geopolitical equivalent of 28 day mandatory confinement in a loony bin before it snaps and randomly hurts somebody.
It is good that for the moment you very definitely do not represent Australia, Bambi.

China delivers yet another attack on Australia and AUKUS
#####
The threat of invasion by China is very real.
I think you underestimate the logistics involved.
It is said that when they invade Taiwan they'll also launch missile attacks and massive cyber attacks against Australia, knocking out all its ability to do anything.
Knock out all the power grids, kill all the software of ships, planes, industry.
Time now to start fighting back...instead of teaching foreign uni students how to hack the place.
The sooner we get some nuke powered, nuke armed subs that can be stationed at sea away from harm, the better.
US and British nuke subs are to rotate thru Perth Western Australia starting soon, my news said.
Hope they're loaded up with nuke missiles ready to fire at a moment's notice.
