Spain planned to 'invade' Australia in the 1790s with 100-vessel armada

Its an extremely stable state. I would be reluctant to think it would still be fought over today if Spain did try to take it.
In fact the British actually used to attack Spanish settlements at the time, and supported piracy against the Spanish Armada.
It has very little to do with actual Australia. It were the British who invaded Australia, killing most of the native population.
Go around Australia and see how many non whites there are. See who has all the wealth on the country.
I wish your statement of fact on this issue had been as well placed as your sentiments.
