Some really good points made. We (myself, wife and three children) are deliberating the big move after securing our visa last year, we went to Perth last October to initiate and pretty much liked what we saw. The thought of "starting again" is very daunting as are the massive initial rental/start up costs. Fortuneatley we don't have too much close family but feel we are scared about missing the whole familliarity thing. The lack of any family/friends already in Perth makes things tricky aswell.
As a few of you have already stated our primary reasons for going is for the kids futures.
Jodipodi you make some fantastic points, I feel we have slowly come to the same conclusions, still have moments of massive doubt though!
