Well picked up Stooge but at least in Tasmania and I am pretty sure the rest of Australia is the same no licence is required any longer. There is ATAS which is an accreditation scheme through AFTA which is voluntary and just a money grab. We are not affiliated with it as we are full IATA and are audited by them and have guarantees in place.
So there are no restriction and no watchdog.
Brave new World!!
