I'll probably move back home after Uni. There's a chance I may move abroad to Denmark for a few years because I'm interested in being forced to learn a different language in everyday living. (However, I don't think my 'disposable income' stretches that far).
To be honest, moving elsewhere seems like a bad career move when I'm "older", so if I'm gonna do it, it will be straight after university.
Edit: My brother has just moved to Australia after getting a Visa and he doesn't find people isolated at all. He lives in Queensland (not sure of exact location) and is absolutely loving it out there and finds the people friendly and way of life very easy-going yet organised.
