Personally I do think you are mad. Is your life that dreadful in the uk to want to move to the other end of the earth with your son and leave behind family support and friends. You'd still have the same daily life routine here. Same **** different country as such. I've been here almost 2 years. I live in Sydney and I do like it for diversity, city and beach life along with the stunning Blue Mountains. On the other hand I miss the beauty of the U.K. Local woodlands beautiful countryside. Culture and depth of history. The build up to Christmas, coming home to snuggle up in front of the fire. Which you can still do here June-August. I'm in a new build now but still miss having double glazing and insulation. I'm lucky as we haven't put down permanent roots and both wish to move back home at some point. But for now we are appreciating Sydney life as its a great City in my opinion.
