Please.................Australia wouldn't evne last as long as Taiwan.
I wouldn't be so quick to dismiss the Aussies, "even if your spelling is good". They have good equipment across the board and play the game in a very high level. Most of all in submarine operations, other naval OPs, and maritime strike. Could they make a contribution that would stop the Chinese? No! But they could make a contribution that the Chinese couldn't afford to dismiss. A Aussie task force wheeling around out in the South China sea, Collins class boats heavy, would be a threat big enough the Chinese would have to divert resources to counter. Even if the Aussies didn't actually fight, a show of force would have some significance. Especially as diplomatic efforst picked up steam.
For Taiwan it would simply be a matter of survival until some kind of help arrived.
Unless you meant, "Please.................Australia wouldn't evne last as long as Taiwan.", that Australia would be invaded and conquered even faster then Taiwan?? If that's what you meant then you are quite mad. Outside the range of their land based air the RAN and the RAAF would slaughter the PLAN piecemeal before they ever got close enough to fire a shot. We've already gone over this so I wont even mention the systems, training, and expertise they have in the Australian service.
