Never been to Australia, or really felt any great desire to. I know quite a few Aussies and most are great fun (A few seem to have whining down to a fine art though...)
I don't hate the idea of visiting, but it seems an awfully long way to go without a real desire to and there are a lot of places, closer, I'd rather go. If work sends me there I'll be happy to go, but I'll spend my own money elsewhere.
If the opportunity came to live somewhere outside the UK and all the conditions were right, I'd certainly consider it, but the myth that everywhere is better than here is true everywhere
I had the opportunity to move to San Francisco once and it seemed great at first (I do like SF), but the job was 'based' there but all the work was somewhere else, so there seemed little point uprooting my family to live in the US, when I'd spend most of my nights in hotels in shit American cities...
