Australia is famous for unique animals like Kangaroos, Koalas, Wombats, Platypuses, Echidnas, Tasmanian Devils, and Quokkas, all marsupials or monotremes (egg-laying mammals) found nowhere else, alongside iconic birds like the Emu and reptiles like the Thorny Devil, showcasing incredible evolutionary isolation.
More than 80% of our plants, mammals, reptiles and frogs are unique to Australia and are found nowhere else in the world. Some of our Australian animals are very well known like kangaroos, dingos, wallabies and wombats and of course the koala, platypus and echidna.
10 of Australia's most unique animals
The fauna of Australia consists of a large variety of animals; some 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles that inhabit the continent are endemic to it.
First recorded in 1840 by the collector John Gilbert, from whom it takes its scientific name, Gilbert's Potoroo was once thought to be extinct. Today, it holds the critical distinction of being the world's rarest marsupial and Australia's rarest mammal.
The vaquita is the most endangered cetacean in the world. With as few as around 10 left, the species will become extinct without a fully enforced gillnet ban throughout their entire habitat.
It's rare to see a quokka without a big 'smile' on their face! This, along with their friendly and endearing personalities, has earned them a reputation as the happiest animal in the world.
Australia's largest terrestrial predator is the Dingo, a native canine that acts as an apex predator, managing herbivore populations and benefiting ecosystem health, though the marine saltwater crocodile is the continent's largest overall reptile predator, while the extinct Thylacoleo carnifex (marsupial lion) was Australia's largest-ever mammalian predator.
The largest species, the spotted-tailed native cat (D. maculatus, also called the tiger cat), has a length of 75 to 130 cm, including its 35- to 55-cm tail. This species occurs in the dense, moist forests of Tasmania and eastern Australia.
The Vaquita (Phocoena sinus), a small porpoise from the Gulf of California, is widely considered the world's rarest animal, with only around 10 individuals left, pushed to extinction by illegal gillnet fishing for other species like the totoaba. Other contenders for rarest include the Northern White Rhino (only two females remain) and the elusive Saola (Asian Unicorn), though population numbers for many extremely rare animals are uncertain.
The quokka is a small marsupial native to Western Australia, often called the “world's happiest animal” because of its adorable, smiling face. 🥺 About the size of a domestic cat, quokkas have round bodies, short tails, and soft brown fur. They are friendly and curious, often approaching humans without fear.
Australia is full of weird facts, including having more kangaroos than people, the world's longest golf course (850+ miles!), pink lakes, a "Dingo Fence" longer than the Great Wall of China, and unique wildlife like the venomous male platypus and egg-laying mammals (platypus & echidna). Kangaroos and emus can't walk backward, symbolizing progress, while the continent hosts the oldest rainforest (Daintree) and is the only one without active volcanoes.
Most scientists believe the chimpanzee is the “smartest animal in the world,” behind humans.
Arguably the most famous Aussie animal of all, the kangaroo can be spotted just about anywhere across the country, but how can we go past a location named after these iconic creatures?
The largest brain on Earth belongs to the sperm whale. The adult sperm whale brain is 8000 cm3, which is more than five times the volume of ours, a comparably small 1300 cm3. A sperm whale's brain weighs up to 9kg (almost 20lbs) which is 6 times heavier than a human brain.
10 Native Australian Animals
The Tasmanian tiger, also called the thylacine, was a meat-eating marsupial that was driven extinct by European colonisers. It once lived across mainland Australia and New Guinea, but its range was limited to the island of Tasmania by the time of British occupation.
Taylor Swift's cats, Meredith Grey and Olivia Benson, are Scottish Folds, known for their folded ears, while her third cat, Benjamin Button, is a Ragdoll, a large, fluffy breed. The Scottish Fold's ear fold comes from a genetic mutation causing cartilage issues, leading to health concerns like arthritis, prompting animal welfare experts to urge caution with the breed despite their popularity.
The kangaroo, Australia's most dangerous animal
Fortunately, the chance that you will come into contact with one of the above animals is small. When driving at night in very remote areas, a kangaroo may appear in front of your car from out of the bush.
Understanding Australia's Megafauna
Australia was once home to a diverse range of large animals, known as megafauna. These included giant marsupials, enormous reptiles, and massive flightless birds. Some notable examples were: Procoptodon goliah: A giant kangaroo.
Dingoes are not a breed of dog. While they may have been domesticated at some point (uncertain) in Asia and were brought to Australia, they are no longer considered domestic.
15 interesting facts about Australia
Quokkas have earned a global reputation for themselves as “the happiest animal in the world”. But it's not just their perpetually smiling appearance that makes them seem cheerful - a result of the shape of their face and panting habit - but also their idyllic island home.
You can't touch quokkas because they are wild animals, and physical contact can spread diseases (like salmonella) to both humans and quokkas, potentially causing mothers to abandon their young due to unfamiliar scents, and they can bite if they feel threatened, despite their friendly appearance. It's also illegal on Rottnest Island, with fines for doing so, to protect their well-being and encourage safe viewing from a distance.
