Sorry to be so negative but..... all aviationists in the Land of Oz should know by now that CAsA the free range and lawful state unto itself, the great money and time waster is IRREPARABLE in its current form.
Since Governments are ignorant of , and happy to have CAsA as 'firewall' in the event of a major accident, why change things?
So it is, and will be ever thus.
And those that wish to continue flying will just have to put up with the BS, shelfware extrodinaire. inconsistencies, cronyism and corruption, unethical and immoral thinking of the bureaucratic class, who are after all keeping us the ignorant av-peasantry and the population at large "safe" for falling aeroplanes and bad headlines.
