Looks like you have the "Bug".
Some real plus points are a secure job offer and your wife is an Aussie which is a huge bonus.
It takes around two years to start to feel fully settled and about 4 years to catch up financially - with your plus points you should be able to trim those times down.
The emotional side is another thing - which only you can really deal with.
A lot of people live with that "what if" in their lives or would love to take the leap but cannot.
You have some cards stacked your way but no one else can tell you what to do.
We really came here because we could and looking for a lifestyle change / challenge. Been here 14 years now.
Thanks for all the useful posts :)
we have decided to make the move!! Shall arrive in mid-Nov and quite excited - but LOADS to do!
Fab to hear you've decided.
Mid Nov should give you plenty of time to get organised your end. Its quite a nice timeframe actually. Arrive here to warmer weather, have a bit of time before the Christmas holidays to find your feet.
Good luck with all the moving.
