just wait until a nil wind CAVOK saturday morning at YSBK, getting a 1 hr delay start if your lucky! oh, and the average 30 min wait in the runup bay for circuits now. and 50% of my entries back into the zone now are met with, clearance not available.
i have heard rumours already of 2 reputable small schools seriously considering throwing in the towel altogether as it not even worth moving interstate now.
IMO GA in OZ is already dead, its no longer self sustainable. in a few yrs YSBk will be back to its self again, not due to traffic leaving, but businesses simply walking away.
