Profile last updated: 13 Aug 2021


The Crescent Nailtail Wallaby (Onychogalea lunata), known also as the Lunated Nailtail Wallaby, is now presumed extinct.

It was marginally smaller than the Bridled Nailtail Wallaby, mainly attributable to a shorter tail. The Crescent Nailtail Wallaby was a medium-sized macropod with a body mass of up to 3.5 kg. It also possessed an ill-defined, pale hip stripe and a 'nail' at the tip of the tail.

The upperparts of the Crescent Nailtail Wallaby were ash-grey with a rufous wash on the shoulders and across onto the flanks. A distinct white crescent spread from the shoulder blades down to the chest, with another white patch along the thigh.


The Crescent Nailtail Wallaby was once quite common in a variety of habitats throughout much of central, southern and south-western Australia, but was unable to withstand the changes wrought by European settlement.

The wallaby remained common, even in agricultural districts in the south-west of Western Australia, until about 1900. It had begun a steep decline by 1908, when the last wallaby was caught in the area. The last specimen of this wallaby to be collected alive was caught in a dingo trap on the Nullarbor Plain in 1928. It to Taronga Zoo in Sydney and the animal ended up in the Australian Museum.

Habitat and ecology

  • The biology of the Crescent Nailtail Wallaby is poorly known. It occupied woodland and shrublands, especially those dominated by Mulga, and ate grass. During the day, it sheltered below trees and shrubs.
