Something that wasn't addressed in the show was how inconsistent CASA is across the country. They hammer some operators for all sorts of minor non issues yet don't take action on others. From what I've seen if you are game enough to challenge CASA in court they will tend to back off.
However I wasn't impressed by the father's call for the old 'world's best practice' in that senate committee meeting. That is not going to solve anything in this country.
