LeP and Plaz, I read the VOR post I quoted at 228 as attributing the lack of E and the over-use of C in Australia mostly to the intransigence of Australian ATC and pilots rather than the meddling of amateurs.
LeP: What if - heaven forbid - Australia introduced real G instead of ForG and reduced the volume of Class C without replacing it entirely with E? You know - set up airspace in accordance with principle rather than perception.
