tinkybelle or ozstamps,

While in Sydney and Melbourne for my Olympics trip in September I will be doing all I can to not be the idiotic tourist. To help, I have read several travel books and visited many web sites to gather information on your cities/country. Any pearls of wisdom that either of you can pass on to me??? Words/gestures/phrases which might have a very different meaning to Australians that will get me laughed at/beat up/put in jail??

When tourists come to my hometown, Juneau, many get off the cruise ships and ask what elevation they are at. As you look over the edge of the dock at the ocean, the common answer is "How tall are you?" before you start laughing.

Thanks in advance.
