Basically the law is so badly constructed that it is meaningless.
CASA can ramp you and do as it likes. You are always guilty of something.
Therefore completely disengage with CASA. This is why I don't attend events like fly ins , the Birdsville races, etc. I do not wish to come into any form of contact with these CASA creatures.
For example, I go diving with Mike Ball on a live aboard dive boat every year. The trip either starts of finishes with a flight to or from Lizard Island.
These flights are timed like clockwork and their schedule is known at least a year in advance - yet other operators have been closed down for precisely the same type of operation when they were deemed to be "stealth" RPT.
