Australia was not actively involved in the united nations and by the time they were (1945) many of the European problems with the aborigines had died down.
Australias history can only be dated back to 1606 as the first recorded European landed on the continent naming it New Holland. Before this date, Australia did not exist. The Aborigines never recorded history so they being in the continent really accounted to nothing. They did not build anything, they did not farm, or create any scientific technologies. The Aborigines were nomadic meaning they did not own the land they merely lived off it. The Aborigines didn't even have a name for the continent. So since it is 2011, Australias history dates back 405 years.
