The organisation operates throughout the Australasia region (Australia, New Zealand, Papua New Guinea and the Pacific).

As an association, ZAA brings its members together to facilitate shared knowledge and continuous improvement in conservation, welfare, biosecurity, science, research, social and community programs.

Using the Five Domains Model,[4] ZAA grants accreditation to zoos and aquariums that demonstrate a commitment to positive animal welfare.

Australian state and territory laws require zoos and aquariums to meet minimum standards for animal welfare.

[7] ZAA acts as a focal point for unifying the efforts of zoos and aquariums in contributing to wildlife conservation.
