Slang terms like that aren't used commonly in Aus anymore despite how we are portrayed in commercials.
Racism (and Fosters <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />) just isn't tolerated.
Most Australians dont even know what a septic tank is let alone that is is rhyming slang for the British term Yank.

So you dont have to accept that we Aussies "just talk like that" because we dont, if someone is using those terms it is because they are trying to get a rise out of you.
