The bilby is found in fragmented populations in Western Australia, including the Tanami Desert, the Great Sandy Desert, and the Pilbara and Kimberley regions
The bilby, a native Australian marsupial, is found in fragmented populations in Western Australia, including the Tanami Desert, the Great Sandy Desert, and the Pilbara and Kimberley regions. The bilby is the largest species in the bandicoot family and has silky grey fur, a long snout, and a slender tongue. They are well-adapted to the semi-arid and arid regions of Australia, with the ability to survive without drinking water regularly, as they get most of their moisture from their food. This makes them well-suited to the desert conditions of Western Australia.
The bilby population in Western Australia is estimated to be fewer than 10,000 individuals, and they are listed as vulnerable to extinction. Their main threats include loss of habitat, competition with introduced species, and predation by feral cats and foxes. These threats have contributed to the decline of the bilby population in Western Australia and across the country.
In Western Australia, the bilby can be found in the following specific regions:
- Tanami Desert: This desert region spans across the Northern Territory and Western Australia, and the bilby population here is fragmented and restricted.
- Great Sandy Desert: The bilby is found in the vast expanse of the Great Sandy Desert, one of the iconic Australian deserts.
- Pilbara Region: The Pilbara region is known for its unique landscape, and the bilby population here is also fragmented.
- Kimberley Region: The Kimberley Region is home to the mighty Fitzroy River and is considered a globally significant biodiversity area. The bilby is found within this diverse and rugged landscape.
Conservation efforts are underway to protect and restore the bilby population in Western Australia. These efforts include captive breeding programs, habitat protection, and partnerships with Traditional Custodians, such as the Martu people, to incorporate Indigenous knowledge into conservation practices. The bilby is an important part of the Australian ecosystem, and these efforts are crucial to ensuring their survival and restoring their population across the fragmented regions of Western Australia.

In southwest Queensland, the bilby can be found in the Mitchell grasslands and some protected areas
The bilby, Australia's answer to the Easter Bunny, is a ground-dwelling marsupial. Once common throughout the Australian mainland, the bilby population has declined significantly over the last century. The bilby is now listed as vulnerable to extinction.
The bilby is well-adapted to the arid conditions of the Mitchell grasslands, with their strong forelimbs and long claws that help them build extensive tunnel networks to shelter from the heat and predators. They are also nocturnal, emerging after dark to forage for food.
The Australian Wildlife Conservancy (AWC) protects the bilby within several feral predator-free areas, including the Yookamurra Wildlife Sanctuary and the Pilliga Conservation Area in NSW. The NAPCo Partnership Area in southwest Queensland also supports some of the bilby's last remaining wild populations.

The bilby has been successfully reintroduced in South Australia, including Thistle Island and the Arid Recovery Reserve near Roxby Downs
The bilby, an iconic Australian marsupial, has faced significant threats to its survival, including habitat destruction, introduced species, and urban development. Once common throughout arid and semi-arid regions of Australia, its range has been reduced due to changes in its habitat. Conservation efforts are crucial for the survival of this vulnerable species.
One successful conservation initiative is the reintroduction of bilbies in South Australia, specifically on Thistle Island and at the Arid Recovery Reserve near Roxby Downs. In October 2020, nine bilbies (four males and five females) were released at the Arid Recovery Reserve with the aim of boosting the gene pool and enhancing the population. This was the third release at the reserve, with previous introductions occurring in 2000 and 2010. The bilbies were humanely captured on Thistle Island, known for its overpopulation of bilbies, using fishing nets.
The Arid Recovery Reserve is a wildlife conservation area located about 550-570 kilometres north of Adelaide, in an area that has faced the challenges of overgrazing by sheep and cattle, as well as the presence of introduced feral rabbits, cats, and foxes. The reserve is focused on the conservation of Australian species and provides a safe haven for threatened species like the bilby.
The reintroduction of bilbies at the Arid Recovery Reserve has been closely monitored by scientists to ensure the bilbies' successful adaptation to their new environment. Radio transmitters were used to track the bilbies to their burrows, and research scientists studied their movements and behaviour. The release was considered a success, demonstrating that bilbies can recolonise their former range in arid zones once threats like rabbits, cats, and foxes are removed.
The bilby's distinctive features, such as its long, silky blue-grey fur, long pink ears, and pointed snout, make it a beloved symbol of Australia's unique wildlife. Through dedicated conservation efforts and the support of organisations like the Australian Wildlife Conservancy, there is hope for the long-term survival and thriving of bilby populations in their natural habitats across Australia.

The bilby is also found in the Northern Territory, including the Sturt National Park and the Newhaven Wildlife Sanctuary
The bilby is found in the Northern Territory of Australia, including the Sturt National Park and the Newhaven Wildlife Sanctuary.
The bilby, also known as Australia's Easter Bunny, is a ground-dwelling marsupial. Once common throughout the arid and semi-arid regions of the Australian mainland, changes to their habitat have reduced their range. The bilby population in the Northern Territory is found within the Tanami Desert.
The Sturt National Park is a protected national park located in the arid north-western corner of New South Wales, in eastern Australia. It was established in 1972 and named in honour of colonial explorer Charles Sturt. The park covers 325,329 hectares and features typical outback scenery of flat, reddish-brown landscapes. It is home to a variety of terrestrial mammals, including the dingo, emu, stripe-faced dunnart, and several species of kangaroo and bat. The bilby was reintroduced to the park in 2020 through the Wild Deserts Program, with 10 bilbies released into a 2,000-hectare protected area. This conservation program aims to increase the bilby population in New South Wales by 17%.
The Newhaven Wildlife Sanctuary is one of Australia's largest non-government protected areas, covering almost 262,000 hectares of central Australia. It is located near Alice Springs and supports a diverse range of habitats, including mulga woodlands, spinifex sandplains, and desert oaks. The sanctuary is home to threatened species such as the Black-footed Rock-wallaby, Brush-tailed Mulgara, and Great Desert Skink, as well as over 175 species of birds. The bilby was reintroduced to Newhaven in 2022, and the sanctuary offers self-guided tours for visitors to explore the arid landscape and observe the wildlife.

The bilby once occupied 70% of the Australian mainland, but its range has been reduced due to habitat loss and predation
The bilby, a native Australian marsupial, once occupied 70% of the Australian mainland. However, due to habitat loss and predation, its range has significantly reduced over time. Bilbies are known for their long ears and pointed snouts, with silky blue-grey fur. They are ground-dwelling, burrowing creatures, well-adapted to digging with their strong forelimbs and long claws.
Historically, bilbies were widespread in arid, semi-arid, and relatively fertile regions across Australia. They could be found in a range of habitats, from arid rocky soils to semi-arid shrublands and woodlands. However, the introduction of invasive species and the impact of human activities have led to a decline in their population. Today, bilbies are classified as a vulnerable and endangered species.
Their range has contracted primarily to remote northern desert areas, such as the Tanami Desert in the Northern Territory, the Great Sandy and Gibson Deserts, and parts of the Pilbara and Kimberley regions in Western Australia. Some populations are also found in southwestern Queensland, including the Mitchell grasslands and Astrebla Downs and Diamantina National Parks.
The main threats to bilbies include predation by feral cats and foxes, habitat destruction, and competition with introduced species such as rabbits. Human activities, such as inappropriate fire regimes and agricultural land use, have also contributed to their decline. As a result, bilbies now occupy only a fraction of their former range, estimated at around 10%.
Conservation efforts are underway to protect and restore bilby populations. Organisations like the Australian Wildlife Conservancy and the Nature Conservancy Australia are working to establish predator-free sanctuaries and national parks to support bilby habitats. Reintroduction programs, captive breeding initiatives, and monitoring efforts are also in place to help ensure the survival of this iconic Australian species.

Frequently asked questions
The bilby is native to Australia and was once found on 70% of the Australian mainland. Today, the remaining wild populations are fragmented and restricted to areas in the Tanami Desert in the Northern Territory, the Great Sandy Desert, Pilbara and Kimberley regions of Western Australia, and southwestern Queensland.
Bilbies are found in a range of habitats from arid rocky soils with little ground cover to semi-arid shrublands and woodlands. They are now most often found in Spinifex, tussock grasslands, and acacia scrublands. They make their homes in burrows that spiral down to make it harder for predators to get in.
Bilbies are nocturnal omnivores that do not need to drink water as they get all the moisture they need from their food. They feed on insects and their larvae, seeds, spiders, termites, bulbs, fruit, and fungi.
The greatest threat to the bilby is predation by feral cats and foxes. Other threats include habitat loss, disease, competition with European rabbits, and inappropriate fire regimes.
