Australia is known for its unique wildlife, but many of its iconic species are at risk of extinction. The country has the highest mammal extinction rate in the world, with 39 Australian mammals becoming extinct in the last 200 years. Climate change, hunting, habitat loss, and invasive species are some of the key threats to Australian wildlife. To prevent further loss, conservation efforts are being made to protect vulnerable species and restore their habitats. These include improving fire practices, reforestation, and translocating animals to more stable environments.

Koalas, greater gliders, platypuses, wallabies and turtles are among Australia's iconic wildlife
Koalas, greater gliders, platypuses, wallabies and turtles are among Australia's most iconic wildlife. Australia has the highest mammal extinction rate in the world, and many species are under threat. The country has lost 100 endemic species since European colonisation in 1788.
Koalas hold deep cultural significance to Aboriginal Australians and are found in eucalyptus forests along the east coast. They rely on these forests for food and shelter, feeding almost exclusively on eucalyptus leaves. They are loved for their adorable features and sleepy temperament, often attracting visitors to Australian wildlife parks and zoos. WWF Australia is working to double koala numbers across eastern Australia by 2050.
Greater gliders are one of Australia's most unique native animals. This remarkable marsupial uses a furry gliding membrane to glide silently through the forest at night. They are found in eucalypt forests on the east coast, where they nest in big hollow-bearing trees. Over the past two decades, their populations have declined by up to 80% in some places due to habitat destruction.
Platypuses are a recognisable symbol of Australia, featuring on the twenty-cent coin and serving as an emblem of New South Wales. They are important in the study of evolutionary biology and hold cultural significance to several Aboriginal peoples. The species gained legal protection in all states where it occurs by 1912 and is now considered "near threatened".
Wallabies are close relatives of kangaroos, and both are herbivores, mainly eating grass. They spend much of the day resting in the shade and are most active in the early morning and late evening. Wallabies breed throughout the year, and newborn joeys make their way into the mother's pouch unassisted.
All six species of marine turtles found in Australian waters are protected under the Environment Protection and Biodiversity Conservation Act 1999. They are recognised internationally as species of conservation concern and are listed in the IUCN Red List of Threatened Animals. The leatherback, loggerhead and olive ridley turtle are listed as endangered, while the green, hawksbill and flatback turtle are listed as vulnerable.

The Mountain Pygmy-possum is vulnerable to climate change and bushfires
Australia is home to some of the world's most beautiful nature and iconic wildlife. However, this rich biological diversity has been declining since European settlement, with 39 Australian mammals becoming extinct over the past 200 years. The country has the highest mammal extinction rate in the world.
One of the species most vulnerable to climate change in Australia is the Mountain Pygmy-possum. These tiny possums, not much bigger than mice, are only found in alpine and sub-alpine regions of southern Victoria and around Mt Kosciusko in New South Wales. They are Australia's only hibernating marsupial.
The Mountain Pygmy-possum is highly vulnerable to rising temperatures. As snow cover lessens, the possum's hibernation period is shortened, impacting its food foraging activities. The possum relies on the snow for insulation from subzero temperatures, and the rock piles where they hibernate provide shelter from lethal summer temperatures. With the snow cover melting earlier, the possum is forced to emerge from hibernation before its food source, the bogong moth, has reached adequate numbers. The bogong moth is also dwindling in numbers due to drought and climate change.
The Mountain Pygmy-possum has also been severely impacted by bushfires, losing critical habitats as a result. The 2019-2020 bushfires caused significant damage to their range, and the species is now highly vulnerable, with only about 2,000 individuals left in the wild.
Scientists have proposed introducing the Mountain Pygmy-possum to a warmer, lowland rainforest environment to save it from the impacts of climate change. This proposal is based on fossil evidence suggesting that the species lived in a more temperate environment for millions of years.

The Numbat is hunted by feral cats, foxes, dingoes and birds of prey
Australia is home to some of the world's most beautiful nature and iconic wildlife. Unfortunately, more than 570 of its native animals are at risk of being lost forever. The Numbat, a small to medium-sized marsupial, is one of them. It is the faunal emblem of Western Australia and survives in two naturally occurring populations in the southwest of the state. The Numbat is under threat from habitat loss and introduced predators. With fewer than 1,000 individuals left in the wild, Numbats are even rarer than Sumatran orangutans and Giant Pandas in Asia.
The Numbat is particularly vulnerable to predation by feral cats, foxes, dingoes, and birds of prey. Its small size makes it an easy target for these predators. Numbats spend their nights hiding in hollow logs or burrows that are too narrow for these predators to enter. They prefer habitats with a certain amount of grassy understorey and hollow logs, dominated by Wandoo, a type of eucalyptus. Numbats have a highly specialised diet that consists almost exclusively of termites, which they find in open areas near the cover of shrubs.
The presence of Numbats is determined by the availability of termites, their primary food source. Therefore, they do not occur in areas that are too wet or too cold for termites to flourish. Numbats are also vulnerable to native reptiles and birds, such as pythons, goannas, and chuditch, which sometimes prey on adults and joeys. While they have evolved alongside these predators, making them more adept at escaping, the introduction of clever predators like feral cats and foxes has tipped the scales against the Numbat.
To protect Numbats, predator control methods such as poison baiting and shooting, as well as predator exclusion through fenced sanctuaries, are necessary. Additionally, habitat destruction poses a significant threat to Numbats when woodland habitats are cleared for farming, development, mining, and human settlements. Land management practices, such as carefully managing fires to prevent large bushfires, are crucial for the survival of this endangered species. Conservation efforts, including captive breeding programs at the Perth Zoo, aim to boost the wild population and prevent the Numbat from disappearing forever.

The Eastern Quoll is susceptible to cane toad toxins, fire and introduced predators
Australia is home to some of the world's most beautiful nature and wildlife, with many plants and animals unique to the country. However, this rich biological diversity has declined since European settlement, with 39 Australian mammals becoming extinct over the past 200 years. The country now has the highest mammal extinction rate in the world.
The Eastern Quoll, a spotted carnivorous marsupial native to northern Australia, is among the threatened species. They feed on invertebrates, fleshy fruits, and a range of vertebrates, including small mammals, birds, lizards, snakes, and frogs. Eastern Quolls living in rocky habitats are larger than those in savanna habitats, such as the Kimberley.
Unfortunately, the Eastern Quoll is susceptible to several threats, including cane toad toxins, fire, and introduced predators. Cane toads (Bufo marinus) were introduced to Australia in 1935 to control destructive beetles in Queensland's sugarcane crops. The toads produce toxins from glands, especially when provoked, and these poisons act on the heart and central nervous system. While some native predators have learned to avoid the poison, others, including the Eastern Quoll, are vulnerable and can die after ingesting the toads. The arrival of cane toads in Kakadu National Park was linked to a decline in some native predators, notably the Northern Quoll, a close relative of the Eastern Quoll.
Fire is another significant threat to the Eastern Quoll. Extensive wildfires, along with habitat degradation from overgrazing and urban development, reduce ground cover and shelter for these small mammals. The impacts of fires are exacerbated by the presence of feral animals, making the Eastern Quoll more vulnerable to introduced predators such as foxes and cats.
To protect the Eastern Quoll, efforts are being made to provide refuge and improve fire management practices. While controlling cane toad numbers across Australia is challenging, localised control methods, such as collecting eggs or humanely disposing of adult toads, can help protect vulnerable wildlife in specific areas.

The Regent Honeyeater population has dropped by over 80% in three generations
Australia is home to some of the world's most beautiful nature and iconic wildlife, with geographical isolation creating animals and plants unique to the country. However, this rich biological diversity has been declining since European settlement. Sadly, Australia has the highest mammal extinction rate in the world.
One such species that has been driven to the brink of extinction is the Regent Honeyeater (Anthochaera phrygia). This medium-sized bird, commonly considered a flagship species, is endemic to southeastern Australia. It feeds primarily on the nectar of a small number of eucalypt plant species and can be found in eucalypt forests and woodlands. The honeyeater is known for its soft, metallic chiming call.
Conservation efforts are underway to protect and recover the Regent Honeyeater population. A National Recovery Plan was formulated in 2016, and captive breeding and release programs have been implemented since 1995. Melbourne Zoo and Taronga Zoo are actively involved in breeding Regent Honeyeaters as part of the captive release program led by the Taronga Conservation Society. Additionally, Birdlife Australia, DEPI, Parks Victoria, and affiliated institutions are also part of the national Regent Honeyeater Recovery Team.
