My parents immigrated here many years ago, I have been in and out of the country living in britain, the us and india. Things have changed over the years ozzies do love to have a go, but most of the time there's nothing malicious about it. They think they are being funny, it works when you're feeling okay, but can be upsetting when you are having a tough time. They even do this when they live overseas themselves, so just learn to ignore it or laugh with them. Adelaide in particular is a city of immigrants, if your next door neighbour hasn't come from elsewhere, you can bet your boots that their parents or grandparents did (no many true ozzies around), it has helped to build a state of workers, most of us working hard because our parents went without for us to get where we have. Adelaide is a small city, very different to Melbourne, I am sure that you will enjoy it and make lots of friends. I have friends you have come over as electricians and they have found work and some even started own businesses which are going well. If however, and I am sure you are, you are worried about the licensing situation, look into it well before you go so that you do not get any surprises. With regards to education my son and wife were here and also my daughter in laws sisters, they did get moved down when returning to the US (but of course that is not britain). They returned to the US and wish that they had stayed here, miss the wonderful lifestyle and the friends and the home that they had here. Would come back but my son has started his own business and now it would be too difficult to move. For what it was worth, they did keep their house here, and we also in turn have kept our home when we have been working elsewhere around the world. We knew that we always had somewhere to go to in an emergency. I believe in the UK you can get a decent rent for properties, if you can afford to rent your house out there and rent a property here for a year until you are sure where you want to settle it could be a good move. It is always good to suss out even suburbs before you make your move to buying a house, and also to check out the schools neighborhoods etcetera. I am sure you will make the right decision, don't let people rain on your parade.
