Helicopter Dude,
We have CTAFs in Australia too; this isn't CTAF.
This is closing high level sectors and approach/tower units and using specific procedures, TIBA, which I guess could be likened to CTAF procedures in terms of broadcasting positions and self separation.
TIBA is not for Aerodromes exactly, it's for airspace which would normally have an ATC service and that service isn't available.
It's becoming clear that ASA and Australia are unique in the modern world using this procedure; all the while CASA says safe and won't review because there is no need; WTF, get on with it CASA at least have a safety audit/review.
Byron you are a disgrace, Russell, there are no words I can use.
