I'm Australian, and I WISH we could ride kangaroos! But, as mentioned, they aren't big enough or strong enough. Also, could be uncomfortable. 
As for everything being poisonous, well... yeah, a lot of it is. But it usually leaves you alone. I live in the suburbs and yes, you do have to stomp the dangerous spiders once in a while, but thats all. I think i've seen about three wild snakes in my life (20 years old).
And last but not least, it is true that our most famous historical figure was a criminal (Ned Kelly for those who don't know).
The beer's good though.

Not very realistic, but hilarious.
