Morno,
Strangely, every major Australian operator, including the one who employed me for so many years, has supported Australia complying with ICAO SARPs, rather than having unique Australian procedures.
At the time, some years ago now, when the policy decision was taken to move towards ICAO compliance in this area, it was significant that AIPA supported the proposition, but AFAP were vehemently opposed.
Another example of the difference between those with some knowledge of the big wide world of aviation, versus those mentally confined within our 12 mile limit.
