The Brush-tailed Rock-Wallaby or small-eared rock-wallaby (Petrogale penicillata) is a kind of wallaby, one of several rock-wallabies in the genus Petrogale.

P. penicillata inhabits rock piles and cliff lines along the Great Dividing Range from about 100 km north-west of Brisbane to northern Victoria, in vegetation ranging from rainforest to dry sclerophyll forests.

P. penicillata or Brush-Tailed Rock Wallaby populations have declined in the south and west of its range, but it remains locally common in northern New South Wales and southern Queensland.

Due to a large bushfire event in South-East Australia around 70% of all the wallaby’s habitat has been lost as of January 2020.

A species of Petrogale, rock wallabies have a dense and shaggy pelage that is rufous or grey brown. The tail is 500 to 700 millimetres long.

The color of the tail is brown or black, the fur becoming bushy towards its shaggy, brush-like end. The weight range is from 5 to 8 kilograms.

The upper parts of this wallaby’s pelage is either entirely rufous-brown, or a grey brown over the back and shoulders with brown fur at the thigh and rump.

The paler under parts may feature a white blazon on the chest. Very dark fur covers the lower parts of the limbs, paws and feet, and on the sides beneath the fore limbs of the animal; a whitish stripe may appear along the side of the body.

The P. penicillata or Brush-Tailed Rock Wallaby is able to negotiate difficult rocky terrain with great agility, their compact yet powerful build is assisted by counter-balancing the long tail and feet suited to holding the animal at precarious edges and on inclined surfaces.

The species favors north facing refuges, and while largely nocturnal in venturing out from shelter they will bask in winter sun for short periods.

In 2018, the southern brush-tailed rock wallaby was declared as the official mammal emblem of the Australian Capital Territory (ACT), although it has not been seen in the wild in the ACT since 1959.
