I'd be suprized if Bankstown does survive, everything it does can be consolidated to WSI, it's current location is squeezed in the middle of the two and with very little airspace. It would make more sense to add a short, second runway to WSI for GA types and send the private/freight/aeromeds there. Training is definitely doomed with a training area more than 30 minutes transit, I can't see YSBK surviving with that sort of cost impost on students and operators.
