Not sure if this has already been made but it should...
Imagine a large paddock with a building in the center. There is a gate to enter the large paddock which is filled with wallabies, kangaroos, and emus. Eucalyptus trees dot the paddock. A path leads from the gate to the center building which is labeled as Australia. There are at least two zookeepers making sure no one does anything stupid. Diverging off the path is a small rest area with benches under a wooden canopy with TV sets highlighting conservation issues in Australia and New Zealand. On one bench is a statue of a wallaby while a statue of an emu guards the rest area. In front of the building is a small pond filled with magpie and cape barren geese.
In the building is an assortment of New Zealand/Australia animals. On the second floor is a restaurant/grill overlooking the kangaroos, emus, and wallabies.
The first floor opens up with a long hallway featuring the small reptiles and amphibians of Australia. The walls are black with a sky light.
The next room is much larger and features the nocturnal animals of Australia (wombats, echidna, and tasmanian devils). All nocturnal animals are exhibited in pits with fake rocks, fake trees, plants, and sand. The wombats have the largest exhibit, tasmanian devils, second largest, and echidnas third largest.
The next room is also nocturnal but it exhibits free flying bats flying around a narrow walkway to the next room.
This next room features four bird exhibits (finches, kiwi, Australian robins, and kookaburra). These four exhibits are situated in a circular black room. In the center of the room is an educational presenter podium for animal ambassadors. This room also has the elevator to the restaurant upstairs.
Another long, black, high ceiling, hallway, this one features two large glass windows into two out door exhibits. Exhibit one is a koala exhibit with three eucalyptus trees and small bushes. Exhibit two is a cassowary exhibit. Both exhibits are not fully enclosed and are separated from the wallaroomu exhibit by moats.
At the end of the hallway is a large aviary for parakeets, guests will be able to purchase feed and feed the parakeets.
The final room in the building is a dark circular room featuring lit up circular pictures of the biodiversity of Australia.
Outside the building is a similar path to the first path leading away from the building and to an exit gate. Bothe gates are marked with large wooden arches.
This is just an idea feel free to add keeper buildings and off exhibit holdings.

Kookaburras tend to be quiet in a perch and would be great acoustical addition to the walkthrough when they laugh loudly
