Australia was never high on my list because it’s one of the least different places from the US culturally but wow! Sydney is truly awesome, what a quality of life. Seems to combine the best of San Diego (weather, beaches), Portland (coffee, coffee, and more coffee) and San Francisco (vibrant downtown and cozy late-Victorian neighborhoods) in one, with friendliness, health, social welfare and a great attitude to life. It seems very prosperous here right now. Plus they are getting all the good immigrants due to sensible immigration policies. Only downside so far: strong currency, so very expensive for us.
