Like Kowaris, an Australian species not exhibited in Australian zoos currently but I would be happy to be corrected. Perth Zoo did have them a while back.
@WhistlingKite24 Not in any zoos that I know of but I saw some juveniles being offered at the VHS Reptile and Amphibian expo here in Melbourne earlier this year so they're definitely around in private hands.
@Yoshistar888 Yes, I have heard of them being in the private trade. Some surprising species out there in private hands here like Emerald Tree Monitors and White-lipped Pythons popping up at Queensland reptile expos for example. Probably with questionable origins.
