I've heard of a few people lnivig on the Islands up the North Coast of Australia such as Hamilton Island. They usually hire young people to work in the resorts over there during the summer and I'm guessing you'd get cheap accommodation? I'm not 100% sure of the details but I know you get time off to enjoy the Island and you'd meet plenty of other young people that would be doing the same thing. I'd definitely want to do it some time during one of my summer uni breaks!
