Southern brush-tailed rock-wallaby
(Petrogale penicillata)
The southern brush-tailed rock-wallaby is a small, agile macropod native to southeastern Australia. Once abundant throughout the Great Dividing Range in Victoria, New South Wales, and southeastern Queensland, the species has experienced a severe decline due to a range of threats. Odonata plays an active role in the multi-agency recovery of this critically endangered species in Victoria.
Physical description
This rock-wallaby grows to around 60 cm tall and is known for its bushy, dark-tipped tail and powerful hind legs. Its footpads are specially adapted for gripping rocky surfaces, making it ideally suited for rugged terrain. Their fur is brownish-grey with a paler underside, and their face is marked by a distinct white stripe on the cheek.
Habitat and distribution
Historically, the southern brush-tailed rock-wallaby was found across the Great Dividing Range. It now survives in two wild populations in Victoria—East Gippsland and the Grampians—as well as in captive populations at Mt Rothwell, Tidbinbilla, and newly established sites in the ACT and Victoria. Preferred habitats include steep, rocky escarpments and gorges that offer shelter and protection from predators.
Behaviour and diet
Nocturnal and secretive, rock-wallabies feed primarily on grasses and herbs. They are agile climbers and use rocky outcrops to escape predators. During the day, they rest in caves or crevices. They are social animals, often forming loose groups around preferred shelter sites.
Breeding
Breeding occurs throughout the year, with a peak in spring and summer. Females give birth to a single joey after a gestation of 30–33 days. The joey remains in the pouch for around 6–7 months and is weaned a few months later. Reproduction can occur soon after pouch emergence, allowing for up to three young every two years.
