The existing Class E in Australia is a stupid, pointless waste of time, that is, E base 8500 and above. As usual, the E over D at Avalon has been hijacked with ridiculous Australianisms, hijacked by bedwetters. That's about the only thing Australian aviation does well, bedwetting. (Yes Captain, I've operated IFR there). If Australia could just get off its high horse and allow itself to be educated on this airspace, safety, real safety not the pontificating bull**** that every organisations safety department fabricates would be enhanced. If you don't understand how E base 700 works, get real experts in to educate you.
