Here’s something that might surprise you: no, Australia doesn’t have wild populations of true squirrels. That odd fact really shapes what you’ll see in the treetops and which animals scurry around up there.
Let’s get into why marsupials like possums and gliders end up filling the squirrel role in Australia. You’ll also find out why attempts to introduce squirrels flopped, and where you might spot one if you’re really keen.
If you’re curious about which Aussie critters act like squirrels, why imports never took off, or where a few introduced squirrels popped up, keep reading — it’s all below.
Are There Squirrels in Australia?
You won’t find native tree or ground squirrels anywhere on the Australian mainland. People introduced a few non-native squirrels back in the late 1800s and early 1900s, but those populations didn’t last.
Native Squirrel Species in Australia
No squirrel species are native to Australia. The continent split off from Eurasia and the Americas millions of years ago, so true squirrels (family Sciuridae) never made it over.
Instead, you’ll spot marsupials that sort of look or act like squirrels, like the squirrel glider and sugar glider. They’re not squirrels—just small marsupials with pouches and different diets.
If you’re looking for classic bushy-tailed squirrels in the wild, you’re out of luck. Zoos or private collections are your only shot at seeing one in Australia.
History of Introduced Squirrel Species
European records mention a few attempts to bring in non-native squirrels to Australian cities in the late 19th century. People reported grey squirrels (Sciurus carolinensis) around Melbourne and Ballarat, and small palm squirrels turned up near Perth and Sydney in a few cases.
Most of these squirrels escaped from zoos or private homes. Local authorities and naturalists tracked sightings and removed many of the animals.
By the early 20th century, people had wiped out or lost track of almost all introduced squirrel populations. A few captive colonies stayed in zoos for a while, but wild, self-sustaining populations never spread across Australia.
Legal Status of Squirrels in Australia
Australian law classifies many introduced mammals as pests if they threaten native ecosystems. In several states, you can’t release or keep non-native squirrels without special permission.
Wildlife and biosecurity agencies work hard to block new squirrel introductions. Tree and ground squirrels could compete with native animals or spread disease.
If you spot a squirrel out in the wild, local wildlife authorities want you to report it. They’ll tell you what to do next and might follow up to make sure no invasive population takes hold.

Native Australian Animals Often Mistaken for Squirrels
Australia has several small, tree-dwelling mammals that look or act a bit like squirrels. They use tree hollows, leap between branches, and munch on fruits, nectar, or insects.
Marsupial Gliders: Sugar Gliders and Squirrel Gliders
Sugar gliders and squirrel gliders are small, nocturnal marsupials that glide on skin flaps between their front and back legs. Sugar gliders (Petaurus breviceps) are pretty common in eastern Australia. They’ve got grey coats and a dark stripe down their backs.
Squirrel gliders (Petaurus norfolcensis) are a bit bigger and have a slightly reddish tint to their fur.
You might see them launch themselves from tree limbs, spreading out to glide up to 50 metres. They’ll eat sap, nectar, insects, and small fruits.
Unlike squirrels, these guys carry their young in a pouch and come out at night. You’ll find them in zoos and wildlife parks, but you might also spot them at dusk in eucalyptus forests.
Possums and Brush-tailed Phascogales
Possums include species like the common brushtail possum and several ringtail possums. The common brushtail possum (Trichosurus vulpecula) has a bushy tail and sometimes visits suburban gardens.
Ringtail possums are smaller, have curled tails, and nest up in the tree foliage.
Brush-tailed phascogales (Phascogale tapoatafa) are carnivorous, mouse-sized marsupials that hunt insects and small vertebrates. They’ve got a thin, brush-like tail and live in tree hollows.
At a quick glance, you might mistake them for small rodents, but they’re marsupials with different diets and reproductive systems. Possums and phascogales are mostly nocturnal, using tree hollows for shelter and playing a similar ecological role to squirrels.
Other Notable Native Fauna
You might also confuse some small native mammals like antechinuses or native rodents with squirrels, but most of the well-known Aussie animals are nothing like them. Wombats, kangaroos, koalas, platypus, Tasmanian devils, and echidnas don’t look or act like squirrels at all.
Koalas stay high in eucalyptus trees and eat leaves. Platypus swim in rivers, and echidnas forage on the ground for ants and termites.
Some little tree-dwelling mammals, like brush-tailed phascogales and tiny native rodents, have that quick, “squirrel-like” movement. Still, they belong to totally different families and have unique features—like pouches or different teeth—that set them apart from true squirrels.
Ecological Roles in the Australian Ecosystem
Native species in Australia actually fill a bunch of the same roles that squirrels do in other places. Gliders, for example, pollinate eucalyptus and banksia as they move from flower to flower, searching for nectar.
Possums and phascogales take care of seed dispersal and help control insect numbers. When they nest in tree hollows, they shape hollow availability for other wildlife—it’s a subtle but important influence.
It’s interesting to note that many Australian tree mammals are nocturnal, while squirrels in other regions often come out during the day. This shift changes when these mammals feed and which predators go after them.
Their presence keeps forests healthy. Strict biosecurity measures also block non-native squirrels from entering and upsetting these delicate balances. If you want to dig deeper, here’s an explanation of squirrels in Australia and why they aren’t native.
