YPJT, yes, the devil is indeed in the detail but the "detail" has to depend on The Act. You can't write detail without referring to The Act. The reason we are in such a mess is because the current Act is deliberately loosely written to maximise CASA's ability to do what it wants with no responsibility for outcomes.
If you get a new Act right, then the detail you ask for will automatically reflect common sense.
By getting "the Act right", I mean framing it in outcome based terms that are amenable to measurement - without that there can be no accountability. The current act deliberately talks about "safety" which is a meaningless nominative word.
