Dick,
I have long thought that CASA does not want more people flying unless it is in a proper high-capacity airliner. Something they can understand - they have no hope of understanding GA so they would rather it didn't exist
You’d be surprised.
When part 61 came into force a couple of years’ ago the airlines (and the FOI’s who inspected them) were astonished to learn that the whole of part 61 was written for GA. It included zero understanding of the way airlines run check and training. This has caused quite a lot of disruption to airline check and training, and is currently not scheduled to be resolved until mid 2019.
