Sorry HBG should have been HBB which is the Syd Harbour Bridge.
So track is YSBK-PRT-HBB-YWOL
You can't actually get that airways clearance off Bankstown groundfor this route, depart as you normally would via Crosswind and call Syd Radar on 124.55 approaching parramatta for a clearance. They'll pass you off to Departures.
It is really important that you put a flight plan into NAIPS for this route at least 30 mins before you takeoff to be sure that you'll get it.
Cheers
