At least in Tasmania.
The BBC reports:
Australian wallabies are eating opium poppies and creating crop circles as they hop around "as high as a kite", a government official has said.
Lara Giddings, the attorney general for the island state of Tasmania, said the kangaroo-like marsupials were getting into poppy fields grown for medicine.
She was reporting to a parliamentary hearing on security for poppy crops.
The BBC article does not discuss whether or not the beloved Looney Tunes character "Taz" has been involved in the crop raiding, although they do mention sheep as another culprit.
