Great post, welcome to Perth..all I will say is, moving IS an option. Your experience will be based mostly on where you settle. Cut your losses before the kids are really, really settled, theyve moved halfway across the world, get the location right and you'll be laughing. Think about as rural as you can get and still go to work, or the best suburb you can afford and really research your schools. That way contact with the antisocial minority will be minimised,ever so important for your kids, and you will thrive. Good luck with it all!
