No invasion would be needed.

All thats needed is to get several thousand armed people to take control of Canberra, Sydney and Melbourne parliament and hold all the politicians under lock and key. And whilst Australia is too stunned to work out what has just happened, land ships and troops in Sydney then Melbourne.

There you have it - control of Australia.

All we need to do is put a bell on the cat!

Several thousand armed people acting in concert without detection?

The Australian military would also still exist even if such a thing could be done.

Not to mention that then landing ships in Sydney and Melbourne would not be allowed by the US.

The Australian populace wouldn't just take it either.

The US may decide that we are past our best before date and choose to cut and run rather than take on a land war in Asia.

You haven't heard of tourists?

You just described a (shitty and likely to fail) invasion.
