Who’s “they”?
It seems like the regulator (CASA) is now so bereft of expertise that it won’t do anything unless a proposal is submitted to it by (in this case) Airservices.
Must be terribly frustrating for CASA to be sitting there, chewing its corporate finger nails, unable to make a regulatory decision unless someone outside the regulator recommends the decision be made.
The subsequent inquiry will be comedy gold, albeit predictable.
