May I respectfully suggest that if the vast majority of pilots have rejected CASA's edict, then they are part of the problem? You would have a much stronger safety case for changing CASA's direction if pilots complied with the direction and it subsequently causes problems on ATC frequencies. At the moment, your case is based on little more than speculation.
Dick seems not to be able to entertain the possibility that the vast majority of pilots actually understand that there are no mandatory broadcast requirements at unmarked, uncertified, unlicensed strips under the 'J curve' or at cattle stations in the middle of nowhere.
This may be because Dick spends most of his life in "transmit" rather than "receive". (But that's just speculation on my part.)
