Wombats are stubby, nocturnal marsupials native to Australia. They are closely related to koalas and are found throughout the eastern and south-eastern states of the country, particularly in the drier areas of South Australia and the southern parts of Western Australia. Wombats are known for their burrowing habits, digging tunnels and designated sleeping chambers in well-drained soil near waterways. They are herbivores, feeding on native grasses, tree bark, and shrub roots. Wombats are solitary creatures, but they sometimes share burrows with other wombats, creating complex networks of tunnels and chambers. While they are iconic in Australia, wombats were declared a pest species in 1906, and their populations have been impacted by competition for food with introduced species such as cattle, sheep, and rabbits.

What You'll Learn
Wombats are nocturnal and herbivorous
Wombats are native to Australia and are among the largest burrowing mammals in the world. They are short-legged, muscular quadrupeds of the family Vombatidae. They are heavily built and have small eyes, short ears, and virtually no tails. Wombats are nocturnal and herbivorous, feeding on grasses, shoots, roots, shrubs, and the inner bark of trees. They have a very slow metabolism, taking around 8 to 14 days to complete digestion, which helps them survive in arid conditions.
Wombats are excellent diggers, with short, muscular legs and sharp claws. They use their digging skills to create extensive burrow systems, which serve as shelter and protection from predators. The backward-facing pouch of a female wombat is also adapted for digging, preventing soil from entering and covering her young. Wombats are known for their distinctive cubic faeces, which they use to mark their territory. By arranging their scat in stacks, wombats avoid the risk of them rolling away and ensure their territorial markers stay put.
As nocturnal creatures, wombats are most active at night, foraging for food and travelling up to 3 km in search of grass, roots, and shrubs to eat. They rely on their sense of smell to navigate and find food, as their eyesight is relatively poor. During the day, wombats typically rest in their burrows, though they may occasionally venture out to feed on cool or overcast days.
The common wombat (Vombatus ursinus) is found in woodlands of hilly country along the Dividing Range in southeastern Australia, from southeastern Queensland through New South Wales and Victoria into South Australia, and in Tasmania. The hairy-nosed wombat (genus Lasiorhinus) is another well-known species, which includes the Southern hairy-nosed wombat (L. latifrons) and the Queensland, or Northern, hairy-nosed wombat (L. barnardi). The Southern hairy-nosed wombat is smaller and lives in semi-arid regions of South Australia, extending into Western Australia. The Northern hairy-nosed wombat is larger and is critically endangered, with a population of only 60 to 80 remaining in Epping Forest National Park in central Queensland.

They are closely related to koalas
Wombats are indeed only found in Australia. They are native to the country, and are considered Australia's favourite stubby marsupial.
Wombats and Koalas: Close Cousins
Wombats and koalas are closely related types of marsupials. They are so closely related, in fact, that they share some unique characteristics. For example, both have backward-facing pouches, which protect their young from dirt as they dig and burrow.
The koala is a member of the koala family, and the wombat is part of the wombat family. Despite being in different families, they are still close cousins in the animal kingdom. They differ in size, with koalas reaching 24 to 33 inches in length and weighing 9 to 33 pounds, while wombats can reach up to 39 inches and weigh between 44 and 77 pounds.
Wombats have short, stubby legs with strong claws for digging, while koalas have sharp claws that facilitate climbing trees. The koala is an arboreal creature, spending its life in the trees, while the wombat is a ground-dwelling animal, living in underground burrows and tunnels.
The koala's diet is highly specialised, consisting of only 30 out of 600 available species of eucalyptus leaves. In contrast, the wombat enjoys a much more diverse diet.
Both wombats and koalas are beloved symbols of Australia, with wombats known for their tough butts and cube-shaped scat, and koalas adored for their fluffy ears and spoon-shaped noses.

Wombats are found in the eastern and south-eastern states of Australia
Wombats are indeed found only in Australia, specifically in the eastern and south-eastern states. They are a nocturnal species of marsupial, closely related to koalas, and are known for their burrowing habits and tough butts. Wombats are solitary creatures, but they often share extensive burrow systems with other wombats, creating complex networks of tunnels and sleeping chambers. These burrows are usually dug near waterways, in well-drained soil.
There are three known species of wombat: the bare-nosed wombat, the southern hairy-nosed wombat, and the northern hairy-nosed wombat, which is one of the rarest land mammals in the world. The northern hairy-nosed wombat is the largest of the three species and can weigh up to 40 kg, though the average weight is around 32 kg. This species is also critically endangered and is now only found in one location: Epping Forest National Park in Queensland.
The southern hairy-nosed wombat and bare-nosed wombat have a more widespread distribution across the eastern and south-eastern states of Australia, including South Australia and Western Australia. Wombats are herbivores and feed on native vegetation such as grasses, tree bark, and shrub roots. They are very territorial with their feeding grounds, marking their territory with scent trails and unique cube-shaped droppings.
Wombats are skilled diggers, using their strong forelegs and long claws to shovel through hard soil. Their backwards-facing pouch is an adaptation that prevents dirt from entering the pouch while the female wombat is digging. Female wombats, or "jill," can reproduce once every two years, giving birth to a tiny newborn, or "joey," that weighs around 1 gram and is less than 3 cm long. The joey must crawl into the mother's pouch, where it will remain safe and continue to feed for at least six months.

They are extremely skilled diggers
Wombats are extremely skilled diggers, a fact that is central to their survival. They are native to Australia and inhabit a variety of habitats, including forests, alpine, heathlands, coastal shrublands, grasslands, eucalyptus forests, semi-arid plains, and arid regions. The type of soil is a critical factor in wombat habitat selection, as it determines their ability to dig the extensive burrows essential for their survival.
Wombats have powerful claws and muscular limbs that enable them to dig through various soil types. They use their front claws to dig, pushing loose soil backward with their hind feet and rumps as they back out of their burrows. A wombat may dig with one front paw for about five minutes before switching to the other. They will use their incisors to cut through obstacles like roots and can excavate several feet of tunnel in a single night. One report mentions a wombat digging through six feet of hard soil in an hour.
The burrows provide shelter, stable temperatures, and protection from predators. They can be 3 to 30 meters (10 to 100 feet) long and up to 3.5 meters (11.5 feet) deep, with multiple entrances and sleeping quarters. The sleeping chamber is typically 2 to 3 meters (6 to 12 feet) from the burrow's entrance, situated in half-light. Wombats may have up to twelve burrows in their home range, with three to four being the main burrows.
The different wombat species have specific soil preferences. Common wombats favour loamy or clay soils found in forested or grassland areas. In contrast, hairy-nosed wombats, especially those in arid environments, prefer sandy or compact soils that retain moisture and support their complex burrow systems. These warrens can extend up to 100 feet in length and often consist of interconnected tunnels and multiple entrances, providing ventilation and shared living spaces.
Wombats' burrowing behaviour not only benefits them but also creates microhabitats that benefit other species. By digging burrows, wombats contribute to soil aeration and nutrient cycling, positively impacting the ecosystems they inhabit.

Wombats are marsupials
Wombats are indeed marsupials, and they are native to Australia. They are short-legged, muscular quadrupeds of the family Vombatidae, and they can grow to around 1 metre in length, with weights ranging from 20 to 35 kilograms. They have small, stubby tails and short ears, with small eyes. Wombats are heavily built and virtually tailless, with fur that varies in colour from sandy to brown, grey, or black.
Wombats are known for their distinctive cubic faeces, which they use to mark their territory and attract mates. The cube shape prevents the faeces from rolling away and ensures they stay put in precarious locations. Wombats are also skilled diggers, able to shovel through several feet of hard soil in a single night. Their backward-facing pouch is an adaptation that prevents soil from entering and covering their young while they dig.
Wombats are nocturnal and strictly herbivorous, feeding on grasses, sedges, herbs, bark, and roots. Their teeth are adapted for gnawing on tough vegetation, with two incisor teeth in each jaw that resemble those of rodents. Unlike other marsupials, wombats have continuously growing rootless teeth, well-suited to their hard-wearing diet.
Female wombats typically give birth to a single young after a gestation period of 20 to 30 days, which then develops in the wombat's pouch for around five to seven months. Wombats are considered sexually mature at around 18 months to two years of age, depending on the species. They are solitary creatures, but the hairy-nosed wombat subspecies is more sociable, sharing large underground burrows with several other individuals.
