Blaxland, in the lower Blue Mountains west of Sydney. With the Great Western, it's only 1hr from the guts of the big smoke to my place (as long as you don't try to travel with the peak hour traffick)
You'd be doing well to get a train that'll get you here in 1 hour. I always find I get to the station just after ones left, so I have to sit for an hour before the next one!
