This shouldn't be a surprise to any commercial pilot / operator, the new regulations have been under development for over 10 years.
Being a "Professional " aviator is more than just getting an aeroplane from point A to B in one piece. Keeping track of changes in the industry and taking the time to provide input to the various consultation processes are professional traits. It's too late to whine about regulations being unreasonable at the 11th hour. If CASA receive only a handful of responses to NPRMs the results are going to be no better than the flight crew licencing debacle. A debacle from both CASA and industry perspectives. That's why there's always an outcry from GA that airlines get a better deal, it's because the airlines participate in the development and feedback processes, whereas GA only complain after the event and then only on forums and in bars.

This will kill whatever there is left of GA Charter.
