I should have stated in the post that Melbourne is where we are thinking.
Thanks for the honest response, I have spoken to quite a few people who have already made the move and on the whole their opinions have been in favour of Australia, but its good to hear other honest opinions also. I had been advised joiner jobs are a plenty and fairly well paid in Victoria, but perhaps this is not the case. As I said above it is the early stages for us and I am keen to do as much research and gather as much info as possible before actually progressing. Thanks again.
