Australia could be an issue given the temperatures and the need to haul water! There is a good book about the perimeter loop....crocodiles and cold beer or something. The crocs weren't as much of an issue as some of the wide open hotter'n hades spaces. That being said..my wife and I worked like dogs our whole life planning for a golden retirement. We never took more than 3 consecutive days off from work, cashed our unused vacation when we changed jobs. Monday will be the firs anniversary of Carol's death from breast cancer at 52. I wish we had just gone and done it. GO DO IT!!!
