Hi guys
I am looking at moving to sydney from Newcastle due to a new job .
My job will  be in greystane area 
My wife is working at Macquarie park area
I can drive where as my wife is dependent on public transport
I have no idea about sydney and its demographics therefore would like some suggestions .
thanks
Edit
I received amazing responses from this community , more than i expected . I tried thanking every comment maker but soon i realised there' too many of them ( which is amazing )
I think so far below seems to make a lot of sense
MacPark 
Marsefiled 
Epping 
Meadowbank
once again thanks heaps for you valuable comments . I love OZbargain




Epping - no changing trains for wife, within striking distance of Parra region.
check train/bus routes into Maq park area. Changing trains can be annoying to some.
