Yes kiang, it's considerably more difficult for Australian zoos to import Artiodactyl hoofstock than primates or carnivores, due to the danger of accidentally introducing disease to Australia's grazing industries.
There is some official reluctance to allow the import of small carnivores (weasels, for example) which may become feral pests should escapes occur.
