Employment Search Help

I am a student at a prominant university in Chicago studying costuming. I have professional experience both backstage and performing and spent last summer with Feld Entertainment, working on costumes for the international touring productions of Disney on Ice. I am very interested in spending my next summer (June-September) working/interning in Australia. However, I'm unsure where to begin my search. Any recommendations as to theater employment websites or companies that may be interested in my skills would be highly appreciated. Thanks!
