majority = artificial communities? nah.. i think u're confused with surrounding suburbs like dural, oakhill, kellyville, rouse hill, cherrybrook, etc.
i can't see ANY good reason to live in the city.. where will u park? live in a 1 bedroom apartment and pay shitloads for it? nup i wouldn't.
if i was rich, i'd live out towards vaucluse/watsons bay area etc.
but ye, blakehurst, wtf?!
