Thanks for all your input, so far.
We'd have to move about 4ish suburbs out to get an affordable decent house and land.
It just feels like when I drive through those suburbs, I never see anyone on the street, and the shops are full of old greek ladies (I have nothing against them, just not in replacement of young mums). I wonder where everyone is? Are there groups of mums having awesome catch ups hidden in back yards? Or are there community halls on back streets where mums hang out? Or is everyone working? Have they driven back to my suburb for some good coffee? Or do other mums just stay home with their kids all day? I'm just not sure if my expectations are realistic...
I just don't want to end up being stuck in a big house with a big yard, with two kids and no friends!
