Apart from its World Heritage and Ramsar convention listings, Kakadu is also subject to international treaties for the protection of other wildlife and habitats:
- Agreement between the Government of Australia and the Government of Japan for the Protection of Migratory Birds and Birds in Danger of Extinction and their Environment (JAMBA)
Forty-six of the 76 birds listed under this agreement are found in the park
- Agreement between the Government of Australia and the Government of the People's Republic of China for the Protection of Migratory Birds and their Environment (CAMBA)
Fifty of the 81 birds listed under this agreement occur in the park;
- Convention on the Conservation of Migratory Species of Wild Animals (Bonn Convention)
Twenty-one of the species listed under this convention are found in Kakadu;
- Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)
- Convention on Conservation of Nature in the South Pacific (Apia Convention)
Parks Australia is also signatory to a Memorandum of Understanding with the South Pacific Regional Environment Programme (SPREP) to facilitate cooperative nature conservation programs in the South Pacific, which has particular ramifications for marine species that occur in the park.
Kakadu is involved in an international Tri National Wetlands Conservation Project being developed by The World Wide Fund for Nature (WWF) Australia. This project aims to exchange expert knowledge in managing wetlands with local indigenous people.
Parties to the project agreement are the management authorities of:
- Kakadu National Park;
- Wasur National Park in Irian Jaya: and,
- Tonda Wildlife Management Area in Papua New Guinea.
These three areas each have similar wetland habitats and are managed with the local indigenous people. The project aims to develop a cooperative arrangement between the three areas to share experiences in wetland conservation, promote best management options and develop a training program. Wetlands in all three protected areas each form a significant stop-over point in their migration for birds on the East Asian/Australasian Flyway.
