I'm going to agree with Glastokitty (pretty sure I always do on these Oz threads), but I emigrated to Perth too, also with no jobs and having never visited before and best thing we ever did. Had been to Sydney a number of times, but believed Perth would suit us better. As a sporty, active family Perth does give us a much better lifestyle. We can drive to a pretty much empty beach, with free parking in 5 mins. I live a fair way out, about 30km, from CBD where I work, but the trains run on time, and regularly, so can be door to door in 30 mins. In mornings they're every 5 mins, coming home every 10 mins.
Working is more relaxed than it was in UK for me, and much, much better paid than I was working in North of England - almost twice as well paid, even taking into consideration higher cost of living. We do have a bigger house, swimming pool, big yard for the kids for about the same as we paid for a 3 bed semi with a tiny back garden, so it is feasible if you're flexible about where you live.
And those are ridiculous stereotypes about Aussie men, I run a team that happens to be all male, and they're all professional, respectful and highly intelligent. Some like sport, but so what, so do I! It's not some weird failing, I've found the Aussie approach to sport, particularly at the level my children are at to be much more healthy and inclusive than when they played soccer in UK.
And yes, it's not year round sunshine, very definite seasons (have been wishing for more sun this past winter). WA itself is such a huge state, even within it the climate is so different. I personally love Margaret river, with the beautiful Boranup forests, vineyards and beaches but slightly cooler, but up North is equally spectacular when you see the Kimberleys etc.
Not to say there aren't issues, I do worry about the use of drugs here that may impact my kids as they grow up, but UK certainly not immune to that problem either, so no regrets here, and you couldn't drag me back to UK.
