Ultralights, you raise an important issue regarding self regulation, and it, in turn raises a question about our own regulation.
Due to the fact that we are not able to self-regulate, it is necessary for us to face sky rocketing insurance premiums to make up for the Seaview Airs out there. Just as American operators have been asked to curtail pay for training programs by their insurance companies.
Once you see an aircraft like a EMB-145 snapped in two after a "training" flight, it will make you a believer that we are incapable of drawing a line on these things.
One thing that Australian Authorities used to be good at was learning from the mistakes of the Americas. Now it seems they are only good at repeating them, as is the case with standards on theory examination and flight crew testing through the bogus ATO system.
