If this animal can turn up in Australia, what else could be out there that some game park/farm etc lost.
And the NT govt has no idea what/where etc regarding which animals have been sold/lost etc.
Now if a pygmy hippo was out there..what about top of the line predators that are renowned for being elusive..
