Aboriginals in Queensland can harvest wildlife under the native title legislation for traditional purposes. The big question that used to be was, did the state wildlife protection laws over ride native title. This question was taken to task by the DEH in regards to the harvest a spearing of a crocodile by a native in the Gulf. From memory I am sure that the High ruled that state wild life acts did not. In view of this ruling, Queensland Parks and wild life or DEH publicly stated that they would no longer prosecute aboriginal people. This included dropping the current charges against an aboriginal who raided huge amounts of eggs from a protected marine rockery of Cairns.
There are many tricky areas yet tested by law in regards to the transfer of wildlife property previously legally harvested. You will more than likely find that once you receive a reptile from a person who has taken fauna under native title you are then breaching the state wild life act for receiving protected fauna.. If you were a guest in their house at the time and ate it with them you probably would be covered.
The law can be a nightmare and can often seem to be unfair. Take for example the fact that you can buy and own a reptile in Victoria but when you legally import that reptile into Queensland under the DEH wildlife act, that fauna is now deemed to be the property of the crown.
