In all fairness, the membership fees for RA Aus are quite well priced. The local RC air club has memberships higher (they claim for insurance...)
I think RA Aus is doing a good job reducing the requirements compared to CASA. I don't need an asic, I don't need medicals, human factors was quite well priced and a good course. The requirements for epirbs and radios, really aren't that expensive compared to the price of an aircraft.
I understand what you are saying but it would appear the gripes you have are more related to CASA issues than RA
