When I visited Sydney in late 2017- early 2018 for a week, I visited three zoos: Taronga Zoo, WILD LIFE Sydney Zoo, and Featherdale Wildlife Park. What I noticed about each one was that they mainly or only displayed native animals. Taronga Zoo had some exotic animals like giraffes, Featherdale had only animals native to Australia except for a few parrots and raptors, and WILD LIFE had exclusively native species. This is completely contrasted to North America, where zoos there keep mostly exotic animals, and native species like coyotes, moose, white-tailed deer, native songbirds, etc are pretty uncommon. I heard recently that birds from other parts of the world may bring disease to Australia if imported there, but does that apply to other animals? Also, why do most zoos in North America try to focus more on exotic species, instead of native ones?
