Hi Iscashe, you didn't strike me as someone who is jumping into this blindly and have obviously already researched the visa types. I don't know about the process for nursing registration but was wondering where in Oz you might choose to live.
We've been in Adelaide for over 20 years and still consider it Australia's best kept secret. Contrary to popular belief, it does not rain and rain and rain all over the country. We have a Mediterranean climate here, perfect outdoorsy climate for approx 10 months of the year and very family friendly. The beaches are great and there are lots of great diving spots close to the metro area. Also, our dog breeder has recently bought 2.5 acres with 3 bed brick house and shedding for $350k, just a 40 minute drive to Adelaide city centre, 15 to 20 minutes to northern suburbs, 40 minutes to beach.
If Adelaide is on your radar, join http://www.pomsinadelaide.com as well. There are loads of nurses on there who have already made the move.
Best of luck, Kazza
