Dick,
Yes, I know G without a transponder requirement is OK at places like Broome and Ballina - but upgrade the airspace to E and add a mandatory transponder requirement and it suddenly becomes unsafe.
Get Real!
Get with the program, old chap. The mandatory CTAF is 30nm which covers VFR up to 10,000ft, pretty-well covering jet profiles inbound (even a nice man in the CAGRO there to talk to just like you've always wanted), then above it's mandatory transponders, just like in E. So yes, as much as you hate it, Australian G is safer than E because of the radio use requirement.
Your astounding lack of knowledge of the Aus NAS doesn't put you in a very credible position when you so vehemently want to change it.
