I don't agree with the comment about isolation, you can feel isolated anywhere if you have that mindset. It's like you have neighbours in Australia like anywhere, in fact you could say people are very welcoming here, as you have a common bond with fellow ex-pats. There is just too much fun to be had here if you want to do anything, its possible. To me if you want to live your life in the here and now, Australia offers that, every weekend can be an adventure. If you live in UK travel is an option but really people live for those weeks out of the UK in my opinion.
