Basically anything you buy over a counter here costs more than the UK, so be prepared for a shock when you do the grocery shopping and so on. WA sounds ideal for you though if you like it reasonably quiet and simple. Greta place to bring up kids too. We are Rockingham area (down south) and wife works in the city (45 min by clean, on-time and plentiful) train and I work locally at a school. Wish we had done it 20 years ago, the reduction in stress vs the UK would probably have added 10 years to my life expectancy. Day care can be expensive and hard to find but like a lot of things it really depends on the situation where you are. We have a daycare centre at our school and it has a waiting list but as they are building a lot of houses I hear that a new one is opening soon, so there will be more places than needed. thats how it goes in a lot of the growth areas, I guess it is harder in the more established areas. PM me if you want any more help. Cheers.
