Buzz words is interesting as you will realise once you start TRT (the Aussie word for supply work) - temporary relief teacher; what areas are key focuses for schools here. You could begin researching Play is the Way and Natural Maths. I know my school is a Jolly Phonics school.
Also are you aware that we have 4 terms throughout the year each approx. 10 weeks long? decd schools start term 1 on 27th January 2015.
Where are you thinking of residing in Adelaide? Some schools work collectively as a scheme so you sign up with the scheme/area to TRT and they ring you in the morning if they need a TRT. So the school rings the scheme and they source the TRT, once your name is out then they would possibly request you etc. It depends how the schools where you are living etc work. I hope that makes sense.
I'll gladly help if I can as only now do I feel things make sense; when I first arrived it was sooooo different (obviously!)
