Questions about Autralian theatre from a Canadian girl.

Hello, I am a Canadian girl who is about to move to Australia; to eventually become citizen.(one of those who met an Ozzy while traveling) I did a three year program in design for the theatre at John Abbott College and would like to study further in costume making to become a costume teacher. I can move anywhere in Australia so I can pick a school. So far I found NIDA, WAAPA, Melbourne Fashion school and TAFE who each offer costume for performing arts. I would like to know what is the best to get some costume/wardrobe work in the industry. Anybody from those school? And also what city is the best for theatre scene? Melbourne or Sydney? Fourth question: Do you have any part time and or shorter course on cutting, millinery or period making costume? Thanks any information is appreciate! Have a great day
