Gee, Capt; I figured you were at least 20 with all that experience and advice that you espouse (probably off your P plates soon).
LoG once you finish HS and your CPL get out there and grab a single by the horns. I can't recommend Kununurra highly enough but then again maybe the Top End will suit you more. Look into MAF. On your initial question I know absolutely nothing about flying jobs in NSW and even less about commuter stuff. Keep PPRuNe-ing.
