Regarding wildlife, Australia is known for its unique and diverse species. From kangaroos to koalas, echidnas to emus, the land down under is home to various fascinating animals. However, one creature that is notably absent from the Australian landscape is the squirrel.
Despite being a common sight in many parts of the world, squirrels have never been native to Australia. This is mainly due to the country’s isolation from other land masses and the fact that squirrels are not strong swimmers. As a result, there are no naturally occurring squirrel populations in Australia, and any sightings of the furry rodents are likely to be escaped or released pets.
While the absence of squirrels may be disappointing for some, it is essential to remember that Australia’s unique wildlife is part of what makes it such a special place. From the iconic kangaroo to the elusive platypus, the country’s native fauna is a testament to the power of evolution and adaptation in challenging environments.
Squirrels Around the World
Squirrels are found in various parts of the world, including North and South America, Europe, Asia, and Africa. They are common in parks and gardens, and some species are kept as pets. While squirrels are widespread, they are not found in Australia.
Squirrel Species Distribution
There are more than 280 species of squirrels worldwide, and they are classified into three types: tree squirrels, ground squirrels, and flying squirrels. Tree squirrels are found in forests and woodlands, while ground squirrels live in burrows. Flying squirrels, as their name suggests, can glide through the air.
The distribution of squirrel species varies depending on their type. For example, tree squirrels are found in North and South America, Europe, and Asia. Ground squirrels are found in North America, Europe, and Asia, while flying squirrels are found in North America, Europe, and parts of Asia.
Some of the most common squirrel species include the Eastern Gray Squirrel, Red Squirrel, and Fox Squirrel, all found in North America. In Europe, the most common species are the Eurasian Red Squirrel and the European Gray Squirrel. The Japanese Flying Squirrel and the Siberian Flying Squirrel are among the most well-known species in Asia.
Australia’s Native Fauna
Australia is home to a diverse range of unique and fascinating animals, many of which are found nowhere else in the world. The country’s isolation from other landmasses has allowed its fauna to evolve independently over millions of years, resulting in a wealth of biodiversity.
Marsupials
Australia is perhaps best known for its marsupials, a group of mammals that give birth to relatively undeveloped young that continue to develop outside the womb in a pouch. Some iconic Australian marsupials include kangaroos, wallabies, koalas, wombats, and Tasmanian devils.
Monotremes
In addition to marsupials, Australia is also home to a group of mammals known as monotremes. These animals are unique in laying eggs rather than giving birth to live young. The most well-known Australian monotremes are the platypus and the echidna.
Reptiles
Australia has many reptile species, many of which are found nowhere else. Some of the most recognizable Australian reptiles include crocodiles, snakes, lizards, and turtles. Unfortunately, the country is also home to several venomous species, including the inland taipan, considered the most venomous snake in the world.
Birds
Australia’s birdlife is also incredibly diverse, with over 800 species recorded nationwide. Some of the most well-known Australian birds include the emu, the kookaburra, and the cockatoo. The country is also home to several species of flightless birds, including the cassowary and the kiwi. Overall, Australia’s native fauna is a testament to the country’s unique natural heritage. The country’s wildlife is fascinating and awe-inspiring, from marsupials and monotremes to reptiles and birds.

Introduced Species in Australia
History of Introduced Species
Since the arrival of Europeans in Australia, numerous species have been introduced to the continent. Some of these species were intentionally submitted, while others arrived accidentally. The first introduced species were domesticated animals such as cattle, sheep, and horses, which were brought to Australia by the British in the late 18th century. These animals were brought to provide food and transportation for the settlers.
Over time, other species were introduced to Australia for various reasons, including hunting, pest control, and ornamental purposes. Unfortunately, some of these species have devastated the Australian ecosystem, as they have no natural predators and can outcompete native species for resources. Examples of introduced species that have negatively impacted the Australian environment include rabbits, foxes, and cane toads.
Current Introduced Species
Today, there are many introduced species living in Australia. Some of these species are considered pests, while others are harmless. As a result, the Australian government has implemented various measures to control the spread of introduced species, including quarantine measures and culling programs.
Some of the most common introduced species in Australia include:
- Rabbits: Introduced in the 1850s for hunting purposes, rabbits are now considered a significant pest in Australia due to their ability to reproduce quickly and damage crops and natural vegetation.
- Foxes: Introduced in the 1850s for hunting purposes, foxes have significantly impacted Australian wildlife, as they prey on native animals such as small marsupials and ground-nesting birds.
- Cats: Domestic cats were introduced to Australia by European settlers in the late 18th century. Today, feral cats are a significant threat to native wildlife, as they prey on many animals, including small mammals, birds, and reptiles.
- Cane toads: Introduced in the 1930s to control pests in sugar cane fields, cane toads have devastatingly impacted Australian wildlife, as they are toxic to many native predators and have no natural predators.
While some introduced species have negatively impacted the Australian environment, others have had positive effects. For example, honeybees were introduced to Australia in the early 19th century and have become essential to the country’s agricultural industry.
Are There Squirrels in Australia?
No, There Are No Native Squirrels in Australia
Despite many other types of animals in Australia, there are no native squirrels. Instead, squirrels are generally found in North America, Europe, and Asia. This is because Australia and the surrounding islands have been isolated from other continents for millions of years, resulting in unique and distinct fauna.
While there are no native squirrels in Australia, a few species have been introduced to the country. These introduced species include the eastern grey squirrel and the red squirrel. However, these species are not widespread and are generally only found in small pockets in certain areas of the country.
Squirrel-Like Animals in Australia
Although there are no native squirrels in Australia, a few animals are similar in appearance and behavior. These animals include the sugar glider, the squirrel glider, and the feathertail glider. These animals are all part of the family Petauridae and are known for their ability to glide through the air using flaps of skin between their limbs.
Another animal that is often mistaken for a squirrel is the native Australian possum. Although possums are unrelated to squirrels, they have similar appearances and behavior. Possums are arboreal animals known for their ability to climb trees and forage for food.
Conclusion
After conducting extensive research and consulting with experts in the field, it can be concluded that there are no native squirrel species in Australia. While there have been reports of squirrel sightings in various parts of the country, these are likely cases of mistaken identity or escaped pets.
It is important to note that introducing non-native species, such as squirrels, can have detrimental effects on the local ecosystem. They can compete with native species for resources and potentially spread diseases.
While it may be disappointing for some to learn that squirrels are not a part of Australia’s wildlife, the country is home to many unique and fascinating species worth exploring and protecting.
