On the thread topic, it seems we are agreed Pearce has busy airspace with 2FTS, 79 Squadron and the RSAF flying training unit present. With this loading, and with Pearce being anecdotally "ripe for a mid air," then the question on sending all training to East Sale has been answered. It can't be done because there would be too many aircraft in the airspace thus making it unsafe to operate, especially with those vicious high mountains and the incredibly cold sea nearby!
