Oz is a lot like the US in terms of the look of their streets and the tv they watch, I thought.
Oz has two principal immigrant (as opposed to the indigenous aboriginal) cultures: the puritans and the larrikins, two cultures that are descended from British settlers.:-
The larrikins are like Crocodile Dundee, they don't give a damn about rules or what anyone says. Their culture comes from the prisoners that Britain sent to Australia in exile, as part of their sentences for stealing and stuff like that.
The puritans meanwhile, are i charge, and love making officious laws, like banning porn on the internet and stuff, and their culture is descended from the prison guards and military officers that Britain sent to oversee the prisoners in the colonies.
These two cultures are alive and well today, meaning that Australian laws are out of control crazy controlling, but Aussie larrikin defiance of being told what to do is equally tough.
We Brits have a lot to answer for! LOL
