It will all come out in a royal commission....people have been saying that ever since the TAAATS transition. What's that - 15 years? You might be waiting a while yet I think.
All that has really happened in that time is 3 or 4 times reshuffling of the management deck chairs - away from Canberra back again and sideways. A few good projects completed. Mindless chasing of false efficiencies by cutting actual ATC numbers whilst at the same time a ballooning (tripling maybe?) of bureaucrats busying themselves with busy work and meetings about finding more efficiencies in the ATC numbers. A crazy scheme to rearrange the whole airspace and management structure and retrain everyone a few times whilst promoting the elite ATC's to ALM (managers). This would some how save heaps of money and be sooooooo efficient for the airlines. Everyone below bureaucrat level was quietly wondering/laughing/eye-rolling about that doozy.
None of that really sounds like good business for anyone but it's not really royal commission stuff either. Just annoying for all concerned. Australian ATC's are actually quite good at their jobs so I would doubt you will see a mid air here. Fingers crossed.
