Folks,
An almost insurmountable problem is the very large number of "drones" that arrive mail order from China or elsewhere ---- what percentage of total sales, I do not know, but in numbers it is in the tens, probably hundreds of thousands for quite advanced RPV --- how do I know --- because I was once associated with a company in China, one of who's divisions did huge mail order /E-Bay/Amazon/AliBaba business with Australia, and he was one of many.
Getting the message across about rules and restrictions to most of his customers would be a thankless task.
Tootle pip!!
