Northern Territory: At the species level, Bettongia penicillata is listed as Extinct under the Territory Parks and Wildlife Conservation Act 2000.

Victoria: At the species level, Bettongia penicillata is listed as Threatened under the Flora and Fauna Guarantee Act 1988.

Scientific name: Bettongia penicillata penicillata

Common name: Brush-tailed Bettong (south-east mainland)

The Brush-tailed Bettong (south-east mainland) was grey-brown in colour with pale yellowish-grey undersides. The sides of the short face and the bases of the ears had a reddish tinge. The base of the long tail was also grey-brown and the last two-thirds were dark brown to black above. The tail had a crested tip. Males and females were similar in appearance and no geographic variation has been reported (Christensen 1983).

Measurements of the Brush-tailed Bettong (south-east mainland) are unavailable, however, the similar Woylie (Bettongia penicillata ogilbyi) is a small, shy, nocturnal marsupial. The head and body length of the Woylie is 300–380 mm, its tail length is 290–360 mm and its weight is 1.1–1.6 kg (Christensen 1983).

This Brush-tailed Bettong (south-east mainland) was able to use its tail, curled around in a prehensile manner, to carry bundles of nesting material (Flannery 1990a).

The Brush-tailed Bettong (south-east mainland) was endemic to south-east mainland Australia (AMMSG 1996). At the time of European colonisation, the species occurred across southern Australia from South Australia, through north-west Victoria to central inland Queensland. The subspecies occurred on the western slopes of the Great Dividing Range and Gould (1863) did not report the subspecies' existence between the NSW coast and the Great Dividing Range. The northern limit of distribution was about 20° S (i.e. around Charters Towers, Queensland) (Finlayson 1963).

The Brush-tailed Bettong (south-east mainland) was described as common in South Australia at the end of the nineteenth century and was gone by 1923. The subspecies has not been recorded in Australia since that time (AMMSG 1996).

The Brush-tailed Bettong (south-east mainland) was associated with grassland, heath and sclerophyll woodland (AMMSG 1996). Other accounts record the subspecies from open eucalypt forest with low woody scrub, tussock grass and occasional bare patches (Flannery 1990a).

The Brush-tailed Bettong (south-east mainland) was adapted to habitat subject to frequent fires. Its food and shelter plants were also well adapted to fire (Flannery 1990a).

The Brush-tailed Bettong (south-east mainland) bred prolifically throughout the year. Like many other kangaroos, it came into heat shortly after giving birth and kept embryos in a kind of suspended animation (called embryonic diapause) until conditions improved. Females were sexually mature at six months. The young spent 90 days in the pouch and there was an interval of about 100 days between each birth. Weaned joeys accompanied the mother at heel until they were displaced when new young left the pouch (Flannery 1990a).

The Brush-tailed Bettong (south-east mainland) had an unusual diet. The bulk of its nutrients (especially in summer and autumn) were derived from the fruiting bodies of underground fungi. The subspecies was also recorded eating bulbs, tubers, seeds, insects and resin. The animal had been seen burying seeds but it was not known if it ever recovered them (Flannery 1990a).

Brush-tailed Bettongs (south-east mainland) foraged from dusk until an hour or two before dawn (Christensen 1983).

Movement information is unavailable for the Brush-tailed Bettong (south-east mainland), however, the similar Woylie occupies distinct individual home ranges of 20–40 ha, which includes a nesting and a feeding area (Animal Diversity Web 2007).

During the day the Brush-tailed Bettong (south-east mainland) rested in a hidden nest in a shallow depression (often under a bush or similar cover) made of grass and shredded bark (Flannery 1990a).

The primary cause of the Brush-tailed Bettong's (south-east mainland) extinction seems to have been land clearing for agriculture (AMMSG 1996), changed fire regimes (Flannery 1990a), hunting (Jones 1924) and feral animal predation.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
