An oldie, but a goodie.
What would be the priority species to bring into Australia at the moment, would it be fresh blood for the likes of bongo, pygmy and common hippo and most antelopes (obviously not possible atm, with the current restrictions).
Perhaps another Francois langur too?
You really know how to work us Aussies up
To be honest, right now I'd like to see more South American species. We have a good range of species to make basic Asian and African exhibits but SA is limited to a few monkeys and macaws pretty much. Melbourne Zoo has been making a bit of an effort recently with the imports of coatis (I especially like that we have another small carnivore) and mara as well as bringing in a Brazilian tapir. I'd especially like one more big cat species (jaguar or cougar), maybe a few more small mammals (jaguarundi, giant otter, etc), and some more tapirs to bump up the small number already here.
Also another bear species for Australians zoos to keep. Ignoring the polar bears and pandas kept at one collection each, the only other representative is sun bears. They fit the bill for being a threatened species, fitting into the south-east Asian theme of most collections, and being endearing but they're just not very impressive. Maybe American black bears so that North America could be a viable themed area with bison and alligators.
