you can buy stuff there,just not animals.
there will be plenty of breeders with stalls at the expo,so if there is something you like,take a buisness card or get their contact details and call them after the expo.i know that there will be plenty of "available" reptiles on display,and some high quality ones as well.one stall holder is selling most of his collection, and they are top notch animals and they will be on display. we just have to do everything legal to keep the EPA happy, so no reptiles can be advertised or sold at the expo itself ,but you can do what you like the next day.but if the EPA catch anyone doing the wrong thing,there will be no more Expo and also ruin further chances of other expos starting up in Queensland.
