The brush-tailed rock-wallaby can be found in fragmented populations roughly following the Great Dividing Range from southeast Queensland to Western Victoria's Grampians. They live on rocky escarpments, granite outcrops and cliffs, which have caves and ledges for shelter and face north for warmth
They graze on native grasses found in surrounding habitat at dawn and dusk. They also feed on the foliage and fruits of shrubs and trees as well as roots and bark
Brush-tailed rock wallabies are highly territorial over their home range, which is about 15 hectares. They are social wallabies and live in family groups consisting of two to five adults with juveniles and joeys.
The brush-tailed rock wallabies' most notable feature, as their name implies, is the distinctively bushy tail. They are medium-sized wallabies with the adults ranging from six to eight kilograms. They are very agile, moving confidently and swiftly around their rocky habitat using their long, thickly furred tail for balance and padded feet for grip
Brush-tailed rock-wallabies have very distinctive facial markings with a white cheek stripe and a black stripe from the eye to the back of the head. Their bodies are brown with grey shoulders and darker feet. This allows them to camouflage themselves well in their habitat and they are often hard to spot
The introduction of foxes has had a major impact on brush-tailed rock wallabies. Foxes were introduced into Australia soon after European settlement and are now well established over most of the non-tropical mainland, including in rock wallaby habitat. They are believed to have contributed to the extinction of several small mammal species.
