We made the move back to the uk after spending 5 years in oz. First year novelty, after that we realised we'd made a massive mistake. Moved back to oz and honestly couldn't wait to get back! It's not perfect, nowhere is, but as much as I like the uk, I just don't like living there. We went back for a visit in November which confirmed we'd made the right decision. We had citizenship so easy for us to return. Good luck, hope you'll be happier on your return.
