Hi, I am a qualified teacher here in Brisbane, made the move 6 years ago. You do indeed need 4 years uni education in order to teach here. Also make sure you have all your university transcripts, as you will need these along with your degree certificate to certify your qualifications to teach here. All in all it probably took me 4 months to get all the paper work together before they would even consider me to be registered here. Relief is a good way into teaching here, in fact after 6 years I am going back to doing relief in one specific school as I love the flexibility of work. Good luck with it all, it certainly is different teaching over here.
