For those of you having a bit of a wobble about moving over, I would say give it a go. We have friends that have come here and some that went back, but most said it was worth doing even if it was'nt for them.
For us the first 18mths felt a bit as if our family in the UK had all passed away. We spoke to them but was'nt the same as popping round Mums for a coffee. It truly does get better though as you friends network builds up. Eventually you good friends become a sort of surragate family and do the babysitting type of stuff.
Our children were then 4 7 and 9 and said they missed the Uk for a long while but now six short years on there is no way they'd go back!
We are now moving from Coromandel Valley to Cherry Gardens 10 mins down the road and having the wobbles again!!!
Hope that this helps oh and by the way if anyone wants to buy my house.....
