Australian reptiles face serious conservation threats from illegal poaching fuelled by international demand and the exotic pet trade. We investigated the extent of illegal trade in a charismatic Australian lizard: the shingleback, also known as the bobtail or sleepy lizard. Using government records, media reports, and online advertisements, we found clear evidence that many shinglebacks have been illegally poached from the wild and are smuggled overseas to be traded as pets. Not only are our findings concerning from a conservation and animal welfare perspective, but they also highlight a major legal loophole. Once shinglebacks are illegally smuggled out of Australia, there are no legal actions available to prevent or regulate overseas trade. To address this, we recommend using an existing and under-utilised legislative tool (Appendix III of CITES, an international treaty) to protect Australian shinglebacks and help to curtail global trade.
