Oceania is known for its unique wildlife. It has the world’s highest concentration of marsupials, animals like the kangaroo, koala, and wombat that carry their young in a pouch. Monotremes also live in this area. They are the only mammals in the world that lay eggs instead of giving birth to live young.
Tropical weather makes Oceania suitable for many parrots and other colorful birds. Some of the islands are home to birds of paradise, the males of which have bright colors, long, usual feathers, and elaborate mating dances. Flightless birds include the large emu and cassowary and the small brown kiwi.
Oceania is also home to some of the most dangerous wildlife in the world. In the oceans are sharks, poisonous fish and octopi, and jellyfish. On land are venomous snakes and spiders. The toothy saltwater crocodile inhabits both realms.

Oceania is made up of many countries, each of which has its own national animals. In Australia, the national animal is the red kangaroo, and the national bird is the emu. In Indonesia, the Komodo dragon is the national animal. Indonesia’s national bird is the mythical garuda, which could be based on the kite or eagle. New Zealand’s national animal is the kiwi, and Papua New Guinea’s is the dugong.
Red kangaroos, the largest species of kangaroo, are commonly found in the open plains of inland Australia. These amazing creatures are known for their remarkable ability to survive on very little water. Males have a distinctive maroon coat with a white face and belly, while females have a bluish-gray coat and are smaller and faster than their male counterparts.
Red kangaroos are a fascinating species, and their impressive adaptations to their environment have made them an icon of Australian wildlife.

Where to Find the Top Wild Animals in Oceania

Each winter, as many as 10,000 humpback whales travel from Alaska to Hawaii. This incredible animal migration starts in November and lasts until around May. They are often seen in the Oceania region.

One of the best things about Oceania is that you can see wildlife everywhere. In Australia, for example, grey kangaroos and wallabies commonly wander into suburban backyards. Lorikeets, cockatoos, and butcher birds may perch overhead as you dine at an outdoor cafe. At certain times of the year, you can view humpback whales from the beach. A huge huntsman spider may even run across the window of your car! In Papua New Guinea, don’t be surprised to find a gecko in your hotel room or a flock of flying foxes in the trees above.
You can also visit zoos or hiking trails to see specific animals. Australia Zoo is a popular attraction that allows you to view many species native to Australia, Oceania, and continents around the world. Oceanic species include fresh and saltwater crocodiles, wombats, dingoes, echidnas, and Tasmanian devils. You can even feed and pet grey kangaroos! Australia Zoo was famously founded by Steve Irwin, the Crocodile Hunter, and it is still operated by his wife and children.
Other fantastic zoos and wildlife parks are located throughout Oceania. In Port Moresby, Papua New Guinea, for example, there are two fine wildlife parks – the Port Moresby Nature Park and Adventure Park PNG. Wild flying fox bats roost overhead. Aviaries are filled with birds of paradise and giant Victoria-crowned pigeons. You can also view crocodiles feeding, cassowaries, and rare tree kangaroos.

Oceania is famous for its host of dangerous animals. In the ocean, watch out for saltwater crocodiles, great white sharks, blue-ringed octopus, stonefish, lionfish, cone shells, box jellyfish, and man-o-wars.
On land, there are venomous animals that vary depending on the location. Some include the common brown snake, tiger snake, Sydney funnel-web spider, redback spider, and jack-jumper ants.
The cassowary has been called the “world’s most dangerous bird,” and the Komodo dragon has also been responsible for human fatalities.
While many dangerous animals call Oceania home, keep in mind that wildlife attacks are still rare. When people are educated about native wildlife and potential dangers, they are usually able to keep a safe distance and live in peace with the animals.
Endangered Animals In Oceania

Many Oceania animal species are endemic or native to just one or a few small islands. With limited range and habitat, these animals can easily become endangered of becoming extinct.
Tasmania, for example, is a refuge for many endangered species that once roamed Australia. This southern, heart-shaped island avoided colonization by some invasive species, such as the dingo. Without competition from feral animals, endangered Tasmanian devils, wedge-tailed eagles, and others continue to survive.
The island of New Guinea is also home to many endangered species, including rare and beautiful birds. Endangered tree kangaroos, pademelons, and the Queen Alexandra birdwing butterfly – the largest butterfly in the world – also live there.
There are also a number of famous extinct animals from Oceania. The thylacine or Tasmanian tiger is perhaps the most famous.
Other well-known extinct animals from this region include the Moa, dwarf emu, dodo bird, and numerous reptiles, bats, birds, and mollusks.
