There is a lot more community spirit in smaller towns. I lived in Brisbane for 3.5 years and made 1 friend the whole time. I have now lived in rural NZ for the same amount of time and I know dozens of people - every supermarket trip I bump into at least 3 people that I know! There are heaps of other SAHM's around (because there aren't many jobs lol) so there are heaps of kid activities and a lot of parent participation in the kindy and school.

Downside: supermarket is small so it doesn't have a full range i.e. only the expensive brands so we pay more for groceries and the fruit and veges never get really cheap during the season like they do in the city. Can also be a bit boring when the weather is bad because most of the stuff to do here is outdoors - bush walks, river, 4wding, camping, fishing etc but you can't just go to the mall if it is raining here. Kid sports is a bit of an issue too, the town has teams but they need to travel over an hour for any matches.

Obviously the job front is something you would need to look in to and would depend on your DH's profession.
