Regent bowerbird, Glossy black cockatoo, Grey-headed flying fox, Mahogany glider, Noisy pitta, Lumholtz's tree kangaroo, Wompoo fruit dove, Striped possum, Northern brown bandicoot, Long-nosed bandicoot, Swamp wallaby, Short-beaked echidna, Boyd's forest dragon, White-lipped tree frog, Double-eyed fig parrot, Mangrove kingfisher, Beach stone-curlew, Pied imperial pigeon.
All in one mix? That would be a huge disaster
First of all: possums will eat birds, chicks, eggs, frogs, smaller mammals (like the gliders) and lizards
Second: Tree kangaroos are pretty prone to stress, and cockatoos and parrots are VERY LOUD
Thirdly: Wallabies could step on the echidnas, as well as on nests
I would separate them into different mixes:
- echidna, forest dragon and tree frog (could theoretically also hold one or two of the smaller brids)
-Possum and bandicoot (Though it's still risky, should be separated when breeding or when babies are present)
-Tree kangaroo and bandicoot (also seperated when babies are present)
-Tree kangaroo and Swamp wallaby could also work, as well as some non-ground-nesting birds, as long as there's plenty of trees and nesting areas where the tree kangaroo can't come
-Gliders would be best in their own enclosure, though could work with echidnas as well
-I'd suggest two seperate aviaries for the rest, as I wouldn't suggest mixing parrots or cockatoos with flying foxes
