Ah, southern wheatbelt. I grew up in Dalwallinu, which is north-east of Perth, usually known as central wheatbelt. Most towns in the area are small and close knit, but can be hard to get to know people in if you're new - be patient and friendly and you'll get there, but don't expect it overnight. If you're running a business or a regular in town it might be a bit easier, I do know it took a while for my mum when we moved because we were on a farming property just out of town and only really went into town every few days or so.

Having family there already will help, and it sounds like a good move for you
