Adam, any time you fancy the REAL Australia, just let me know.
Contrary to what you saw, "dunnie" is only a nickname here.
I have only one warning to Americans (and Canadians, but they usually have more sense in this matter)..DO NOT be tempted to try Vegemite, it's foul stuff, worse than (traditional) haggis.

I went into an Australian Goods shop in San Antonio last year. It was funny to see what the Americans considered dinky di aussie to sell.
