I recently done a RePL through a reputable trainer a few months ago, I was actually very surprised how dangerous drones can be particularly given that anyone with absolutely no idea can buy one off the shelf and have the thing in the air within about 15 minutes if they really wanted to and get up to no good with it very quickly...........
CASA currently have a NPRM out to tighten up the licensing rules which will help, however they aren't targeting the hobby flyers who are the high risk users. The drone manufactures should be locking their software down to prevent idiots flying them near airports, above 400 ft, at night, etc.
Jack the fines up 10 fold with time behind bars might the the way to go!
