Yeah, don't think so. To really make a scam like that work you'd need to have a quiet network get the word around that a certain flight, departing at a certain time will be landing at a certain port every day/ week. Wouldn't take long before CASA are waiting at the other end.
The US actually nominates a category known as Commercial Air Tours and for mine, it appears to be very effective as a way to further business opportunities.
This is not about common safety standards (Part 135) btw, its about smarter regulation to unlock business opportunity for GA operators.
