CASA did "seek to publish" and, alas, appears not to have found how to.
If anything is eventually published, my prediction is that it will say something like CASA was already taking measures to reduce, where appropriate, the regulatory burden on GA.
The 'expectation' is rendered practically meaningless by "where appropriate". That means whatever CASA decides is "appropriate". There is no external benchmark against which to measure that. (And the Minister won't do squat, anyway, if the 'expectation' isn't met.)
