Oh just one other thing I though of. If you are coming to do the course over here or I guess even to go straight into a job make sure all your vaccines are up to date. I knew I had had vaccines as a child and as a nurse but didn't think about the fact I would be asked for proof. I have had to have serology done for mumps, measles, rubella, tetanus, diptheria, pertussis, hep b, varicella zoster. I also had to have a mantoux even though I have had a bcg in the past and a chest xray as part of my medical to get in the country!! My mantoux was therefore positive resulting in having to have yet another xray. Thankfully I have managed to have all this done for free using medicare (apart from having to buy one vaccine as for some reason had no immunity for mumps).
So I guess what I'm saying is get it done before you come over cos its a right hassle. Although it hasn't really cost me, it has taken 4 visits to GP, one visit to radiology, visit to pharmacy, and all in an area I don't know, and am car less as staying with a host family while doing this course in Melbourne.
