Brush-tailed rock-wallaby range

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. It 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 sclerophyl forests. Populations have declined seriously in the south and west of its range, but it remains locally common in northern New South Wales and southern Queensland.[3]

Introductions

As part of the acclimatisation movement of the late 1800s, governor Grey introduced this and four other species of wallabies (including the rare parma wallaby) to islands in Hauraki Gulf, near Auckland, New Zealand, where they became well-established. In modern times, these populations have come to be viewed as exotic pests, with severe impacts on the indigenous flora and fauna. As a result, eradication is being undertaken, after initial protection for review of their Australian populations and the return of some wallabies to Australia. Between 1967 and 1975, 210 rock-wallabies were captured on Kawau Island and returned to Australia, along with thousands of other wallabies.[4] Rock-wallabies were removed from Rangitoto and Motutapu Islands during the 1990s, and eradication is now underway on Kawau. Another thirty-three rock-wallabies were captured on Kawau during the 2000s, and returned to Australia, before eradication began.[5][6]

In 2003 some Kawau brush-tails were relocated to the Waterfall Springs Conservation Park north of Sydney, New South Wales, for captive breeding purposes.

Due to an escape of a pair in 1916, a small breeding population of the brush-tailed rock-wallabies also exists on the island of Oahu in Hawaii.

Attempts at reintroduction into the Grampians National Park during 2008-12 were not successful, largely due to fox predation.[7] Nevertheless, March 2017 saw the emergence of a fourth offspring, bringing the total number of rock–wallabies present within the Grampians National Park to eight.[8]
