Hi Kerry,
The test consists of writting, listening ,reading and oral test. The reading consists of reading a piece of text and extracting information from it to answer some questions. The listening exam, you listen to a tape recording then answer some multiple choice questions based on what you just heard. For the reading part, I would swat up on punctuation, spelling, and how to correctly set out a letter. I think I had to write a letter to my local council complaining about the rubbish, I also had to write a short essay on my thoughts for and against children being left home alone. They are looking for you to display good reasoning skills and a good range of vocabulary so plenty of big words!! For the oral test, I had to talk about myself, where I lived, any local issues and about my personal views on issues such as climate change and the global economy etc. the exams are pretty much like when you were at school, no talking or looking around the room, put your pen down when told etc. The oral test was easy and the assessors are really nice and will put you at ease.
Do you have any preferences on which suburbs you would like to live in? North or South of Adelaide etc? My daughter was 16 when we arrived in January so I don't know much about primary schools etc, but others will be able to help more if you have an idea of where you would to settle.
