I spoke to some Aussies while I was down there. They had been moving around some Chinese/Thai Gear. They nearly got nailed for dealing. Just as they knew they were about to be searched, their buddies packed everything in promoboxes for noname companies. The cops didn't really believe their claims that they got the stuff by accident, but since the guys were respectful and cooperative they got off on some kind of probation and all their potential gear was seized. They also said that if you don't have a prescription to use needles and syringes, you get fines and jail for two years even without posession. Farms, Hospitals, and Vet clinics are places exempt from most of these penalties and searches.
