Truthfully, I think one of the big issues with Australian sections in zoos is that not many zoos are investing in the region. While I can name plenty of zoos who have invested in new African, Asian, or Neotropical complexes in recent years, I can only think of a few who have done the same with Australian complexes. Really, if zoos put as much effort into building Australian exhibits, we'd be having a much different conversation, but for now let's talk about the ones being built: most Australian exhibits being built don't focus on Australian wildlife as a whole, but are just focused on providing an exhibit for one common animal: the kangaroo. Granted, oftentimes these kangaroos are mixed with other macropods and/or emus, and perhaps a few aviaries are thrown in with cockatoos and kookaburras, but the focus of a good Australian habitat should be on much more than this, as there are other Australian species around in decent numbers, with one caveat: they aren't typically exhibited outdoors. Therefore, a good Australian complex should feature both indoor and outdoor sections. Outdoors, there can be a kangaroo/wallaby walk-through exhibit (I for one stand by these as being good exhibits when done correctly, they're popular with guests and allow a unique way of seeing the macropods), but try to incorporate at least one species other than red kangaroo and bennett's wallaby. Try to exhibit some of the rarer macropods, such as grey kangaroos, or parma, swamp, yellow-footed rock, and tammar wallabies. But, most of the Australian species can be housed in an indoor area, as the following are all well-represented in zoos:
- a number of Australian parrot species including eclectus parrots, multiple cockatoo species, etc.
- laughing kookaburras
- tawny frogmouths
- masked lapwing
- Australian wood ducks and spotted whistling ducks
- blue-faced honeyeaters
- green tree pythons
- woma pythons
- bearded dragons and frilled lizards
- carpet pythons
- fly river turtles and australian snake-necked turtles
- white's tree frogs
amongst other birds and herps also found in decent numbers in the region. This is what is necessary to develop a good Australian exhibit, ideally featuring at least one more small mammal if possible, such as koalas, or an underrepresented personal favorite: the little blue penguin!
Overall, however, rather than focus on Australia, I'd rather see zoos focus on habitats of Australasian wildlife, which in addition to those species above opens up some more options from nearby islands:
- Crowned Pigeons, Matschie's Tree Kangaroos, and Birds-of-Paradise of New Guinea
- Northern Brown Kiwi of New Zealand
- various fruit dove species
- northern sulawesi babirusa
and various other Australasian, but not Australian wildlife.
