I'm not holding my breath and I'm going to make a prediction....
Based on Ten years studies of psychopathic narcissism in management, I believe that you will get the shock of your life when this review is released and you hear the Governments response.
Yes folks, the situation will only get worse. you are about to receive an even bigger dose of the current corruption and regulatory muck. CASA powers will be increased and it will continue its current behaviour totally unchanged. It will then attempt to get revenge on its detractors if they can be identified, probably by enforcing a process of micro management and further prescriptive regulation.
To put that another way, CASA will have argued and it will be accepted that the reason for industry despair is that CASA hasn't got enough resources. The answer therefore is to give CASA more, more staff, more powers, more lawyering, more layers of management, more Boards and more power to tax you for it.
Truss will be fobbed off by the making of cosmetic changes (greeted by CASA with the magic words "This changes everything!") but the iron ring will remain and be given more and deeper powers to regulate you out of existence.
To put that yet another way, Truss is no Frodo Baggins. He will not destroy the ring of power by throwing it into the crater of Mt. Doom.
