What You'll Learn
Marsupials: koalas, wombats, kangaroos, and quokkas
Marsupials are mammals that carry their young in a pouch. Australia is home to about 140 species of marsupials, including koalas, wombats, kangaroos, and quokkas.
Koalas are marsupials that typically inhabit open eucalyptus woodland, as the leaves of these trees make up most of their diet. They are largely sedentary and sleep up to 20 hours a day. Baby koalas are called 'joeys' and they hide in their mothers' pouches for the first six to seven months of their lives. Koalas are listed as a vulnerable species by the International Union for Conservation of Nature and are now officially listed as endangered in the Australian Capital Territory, New South Wales, and Queensland.
Wombats are short-legged, muscular marsupials that are native to Australia. They have small, stubby tails and weigh between 20 and 35 kg. They are found in forested, mountainous, and heathland areas of southern and eastern Australia, including Tasmania and central Queensland. Wombats have a distinctive backward-facing pouch, which prevents soil from entering it while digging. They are mainly nocturnal and crepuscular, and they produce cube-shaped faeces to mark their territory.
Kangaroos are another well-known Australian marsupial. They have large, powerful hind legs, large feet adapted for leaping, and a long muscular tail for balance. There are also tree-kangaroos, which inhabit the upper branches of trees in the tropical rainforests of New Guinea, northeastern Queensland, and some islands in the region. Like most marsupials, female kangaroos have a pouch where joeys complete their postnatal development.
Quokkas are small marsupials that resemble kangaroos and are found in a small range in the southwest of Western Australia, including Rottnest Island and Bald Island. They have well-developed hind legs, rounded ears, and a short, broad head. Quokkas are able to climb small trees and shrubs, and they sleep during the day in Acanthocarpus preissii, using the plants' spikes for protection. Females give birth to a single joey, which stays in its mother's pouch for six months.

Reptiles: snakes, saltwater crocodiles, and turtles
Australia is home to a diverse group of reptiles, with over 830 species, 89% of which are endemic. The most species-rich group is Squamata, which includes snakes and lizards.
Snakes
Australia is known for its venomous snakes, which are particularly dangerous due to their venomous bites. However, it is important to note that there are no poisonous snakes in the country. Snakes are especially diverse in the arid regions of Australia, where they find refuge in Spinifex grass, which provides a relatively cool and moist environment.
Saltwater Crocodiles
The saltwater crocodile, or Crocodylus porosus, is the largest reptile in the world and is native to the northern coastal areas of Australia. They are found in coastal rivers and swamps in the northern and northeastern regions of the country. Saltwater crocodiles are known to view humans as prey and have been responsible for several human deaths.
Turtles
Australia attracts all marine turtles except for the Kemps Ridley Turtle. The Flatback Turtle (Natator depressa) is unique to northern Australia and its neighbouring islands. Marine turtles have flippers and live in the sea, while freshwater turtles have swimming legs and live in freshwater habitats. Freshwater turtles can be found in all states and territories of Australia except Tasmania. The most important breeding ground in the Pacific for the green turtle is Raine Island, off the coast of Queensland.

Birds: kookaburras, emus, and parrots
Australia is home to a wide variety of birds, including kookaburras, emus, and parrots.
Kookaburras
Kookaburras are native to Australia and are known for their distinctive call, which resembles human laughter. This call has been widely used in films and television shows, such as Tarzan and the Green Goddess (1938), The Wizard of Oz (1939), and Swiss Family Robinson (1960). There are five species of kookaburra found in Australia, with the laughing and blue-winged species being the most well-known. Kookaburras are sexually dimorphic, with males having blue tails and females having reddish-brown tails. They are carnivorous and feed on mice, snakes, insects, small reptiles, and the young of other birds.
Emus
The emu is a species of flightless bird that is endemic to Australia. It is the tallest native bird in Australia and the second-tallest bird in the world, reaching up to 1.9 meters (6 feet 3 inches) in height. Emus have soft, brown feathers, a long neck, and long legs, and they can run at speeds of up to 48 km/h (30 mph). They are omnivorous and can go for weeks without eating. Emus can be found in various habitats across Australia, including savannah woodlands and sclerophyll forests, but they are less common in heavily populated areas.
Parrots
Australia is known as the land of parrots, with 56 species calling the country home. Australian parrots are large, colourful birds with powerful bills for cracking seeds and nuts. They feed on fruit, nectar, and insects, and many depend on hollows in mature trees to nest. Some of the most common parrot species in Australia include the King-Parrot, the Eastern Rosella, the Western Rosella, the Mulga Parrot, and the various cockatoo species such as the Little Corella and the Yellow-tailed Black-Cockatoo.

Marine life: reef sharks, rays, and whale sharks
Australia is home to a diverse range of marine life, including harmless reef sharks, rays, and whale sharks. The Great Barrier Reef, one of Australia's iconic natural wonders, is a haven for marine creatures. It is home to approximately 1,625 fish species and six of the world's seven types of sea turtles. The reef also hosts harmless reef sharks and rays, as well as an array of other marine life.
While some shark species are known to be dangerous to humans, such as the white shark, tiger shark, and bull shark, it's important to remember that shark attacks are rare. The Australian government is committed to conserving shark species and has implemented measures to protect them, including prohibiting shark finning in commercial fisheries.
The Ningaloo Reef in Western Australia is another hotspot for marine life. It attracts whale sharks, which are the world's largest living fish, growing up to 18 meters in length and weighing up to 34 tonnes. Whale sharks gather at Ningaloo Reef from April to July, offering tourists a unique opportunity to swim with these gentle giants. The reef is also home to humpback whales, and tourists can join them on their migration journey, following sustainable practices that respect the whales' behaviour.
Australia's coastline offers a range of thrilling experiences, such as swimming with dolphins, cage diving with sharks, and snorkelling with manta rays. The Neptune Islands, off the coast of South Australia, provide an adrenaline-pumping experience of diving with great white sharks in a secure underwater enclosure.
The conservation of marine life is a priority in Australia, as evidenced by the EPBC Act, which prohibits harming or disturbing listed threatened species without a permit. Additionally, several shark and ray species in Australian waters are protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Endangered species: Tasmanian devils, northern hairy-nosed wombats, and eastern quolls
Australia is home to a diverse range of unique animals, including iconic species such as kangaroos, koalas, and platypuses. However, some Australian species are facing the threat of extinction. Here, we will focus on three endangered species native to Australia: Tasmanian devils, northern hairy-nosed wombats, and eastern quolls.
Tasmanian Devils
Tasmanian devils (Sarcophilus harrisii) are the largest carnivorous marsupials in the world. They are endemic to the island of Tasmania, located off the southern coast of Australia. Tasmanian devils are stocky, with powerful legs, and can weigh between 4 kg and 14 kg. They have distinct dark brown to black fur, sometimes with hints of red-brown, and a large white stripe across their breasts. These nocturnal creatures are known for their powerful jaws and teeth, which give them one of the most powerful bites of any mammal relative to their size.
Tasmanian devils were once targeted by farmers who believed they were killing livestock, leading to a significant decline in their population. While they are now a protected species, they face new threats. A contagious, tumorous cancer, known as Devil Facial Tumour Disease (DFTD), has caused the deaths of tens of thousands of individuals and is the primary reason for their endangered status. Additionally, habitat destruction and roadkill incidents further contribute to their population decline.
Northern Hairy-Nosed Wombats
Northern hairy-nosed wombats (Lasiorhinus krefftii) are one of the rarest land mammals in the world and are critically endangered. They are native to Australia and were once found across New South Wales, Victoria, and Queensland. By the 1930s, their population had drastically decreased, and they were believed to be extinct. However, a small group of around 30 individuals was discovered in Queensland's Epping Forest National Park.
These wombats have soft, grey fur and are distinguished by the fur on their noses, longer pointed ears, and broader muzzles compared to other wombat species. They require deep sandy soils to dig their burrows and depend on a year-round supply of grass as their primary food source. Northern hairy-nosed wombats face threats such as wild dogs, fire, flood, and disease. Conservation efforts have been implemented, including the construction of a predator-proof fence around their habitat at Epping Forest National Park.
Eastern Quolls
Eastern quolls (Dasyurus viverrinus), also known as eastern native cats, are medium-sized carnivorous marsupials. They were once found across southeastern mainland Australia but are now considered extinct on the mainland, with their range restricted to Tasmania and Bruny Island. Eastern quolls inhabit a variety of environments, including rainforests, heathlands, alpine areas, and scrublands, but they prefer dry grasslands and forest mosaics.
Eastern quolls are solitary hunters, primarily feeding on insects, small mammals, birds, and reptiles. They are nocturnal and spend their days resting in dens or natural crevices. The species is facing threats from predation by introduced predators like red foxes and feral cats, as well as unseasonal weather events. Conservation efforts have led to the reintroduction of eastern quolls to fox-proof fenced sanctuaries in Victoria and the Australian Capital Territory.
