Not much I can add that hasn't already been said. Sounds like somewhere in the inner west would ideal for you given your reasons for moving but yeah, gotta weigh up the financials of that. If you look at the cityrail map, I live about a 5 minute drive from Seven Hills station on the Western Line. I got a train to Town Hall in the cbd last night, takes about 50 minutes from here, but that was also a stop-at-every-stupid-backwater-station-non-express-train...

Be keen to catch up at some point when you're around too.
