I have no idea where the 'official' boundaries are, but in my mind, the extremities would be Engadine in the south, Campbelltown in the south-west, Penrith to the west, Richmond to the north-west, and Hornsby (or Cowan) in the north.
With the way that the population is growing, it will only be a matter of time before we engulf Wollongong, Gosford (or even Newcastle!) and Katoomba.
Camden is not
that far from Campbelltown, and there is a lot of development going on in that area- perhaps one day even that town will enter the 20th century..
