That's an unfair stereotype, alright? All we do with kangaroos is cull 'em, eat 'em and crash our Utes into 'em.
I'd say without the ever watchful eye of other nations on us we would turn into a bunch of drunk maniacs who beat and rape anyone that couldn't be identified within three seconds..
Most parts of central Australia are already like that. Australians are basically the Orks of our species. And proud of it.
Excuse me, those are called aboriginals and they are NOT human, nor are they Orks because Orks at least have some sort of motivation to do anything.
Because back when australia was a big thunderdome/prison island, the ugliest males won the right to mate with the best looking females through combat, but because of countless generations of incest and the fact that all aussie women looked like car crash victims to begin with australia is now inhabited by rat-like monsters that the teenage mutant ninja turtles have to fight, apparently.
would you like a somalian kiss? its like a regular kiss except afterwards we rape you, burn your house down, and slaughter you children like dogs
