Oh, Veronica, that's my dream trip!!! Welcome to the board, I hope you have a blast!! I will check with my son, he went a few years ago during high school, but I'm sure he remembers some of the things he did or thought about. Can't remember if he went to Melbourne but I know he was in Sydney.
I sure hope you will post your trip report and any pics when you get back. We would all love to see them, me especially!!! We love to travel, vicariously if necessary!!
