Missingtheseasons

My husband and I have been in Oz for over 12 years and are considering the move back to the UK. I personally, miss family and friends, the country pubs, the history, the changing seasons (we live in Cairns where there are two seasons; hot and wet and hot and not so wet), the gentleness of the wildlife, Marks and Sparks, Tesco (yes really). My husband has never really settled and misses Scotland. Our concern is the kids who are 12 and 10 years old. They have been on holiday to the UK and absolutely loved it. I know if we told them we're thinking about going back, they'd be thrilled. However, they only have what they experienced during four weeks of holiday and more than anything (and they were in the UK in January/February) Im worried they will hate the weather and the cold. OK, there's plenty of rain where we live but its warm rain and we live five minutes from the beach. Has anyone in a similar situation made a successful and happy move back?
