Why is Australia called Australia?

I dont know, why is it so?

So none of you Aussies know?
How sad can that be.
No knowledge and less pride…

Thanks for that sweeping generalisation, Johan. What country do you come from so we can apply a derogatory stereotype?

It comes from Terra Australis, being the unknown great southern continent marked on maps before actually located by Euro explorers.

Heck, even I know, it is one of the many pieces of often meaningless trivia rammed down ever school kids throat in this country.
