New South Wales: At the species level, Bettongia gaimardi is listed as Extinct under the Threatened Species Conservation Act 1995.

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

Scientific name: Bettongia gaimardi gaimardi

Common name: Eastern Bettong (mainland)

Wakefield (1967) consolidated two species (Bettongia cuniculus and B. gaimardi) into a single species with two subspecies: the extant Tasmanian Bettong (Bettongia gaimardi cuniculus) and the extinct Eastern Bettong (mainland) (Bettongia gaimardi gaimardi).

A description of the Eastern Bettong (mainland) is unavailable, however, the closely related Tasmanian Bettong has the longest fur and the lightest coloration (light brown with white flecks) of all Bettongia. The long tail is semi-prehensile and gradually darkens from the base to the tip, but ends with a white tip. The belly is very light in colour (Fisher et al. 2001; Hutchins et al. 2003; Rose 1986, 1987; Rose & Rose 1998; Rose et al. 1998; Wakefield 1967).

Measurements of the Eastern Bettong (mainland) are unavailable, however, the closely related Tasmanian Bettong has a small, compact body, with an average total length of 65 cm. The tail of the Tasmanian Bettong tends to be slightly longer than its head-body measurement, although both range between 32–33 cm in adults. Males are slightly longer and thinner than females, although sexual dimorphism is not pronounced. The Tasmanian Bettong weighs 1.2–2.3 kg (Fisher et al. 2001; Rose 1986, 1987; Rose & Rose 1998; Rose et al. 1998; Wakefield 1967).

The Eastern Bettong (mainland) disappeared around the 1920s (Menkhorst 2008). The Eastern Bettong (mainland) was formerly distributed along the coastal areas of eastern Australia, from south-east Queensland to the south-east tip of South Australia (Wakefield 1967).

Based on studies conducted on the Tasmanian Bettong, it is likely that Eastern Bettongs (mainland) were associated with grassland areas, heathlands and sclerophyll woodland (Rose & Johnson 2008).

Based on studies of the Tasmanian Bettong, the lifespan of the Eastern Bettong (mainland) was likely to be between three and six years (Fisher et al. 2001; Rose 1986).

Based on studies of the Tasmanian Bettong, it could be assumed that male Eastern Bettongs (mainland) did not partake in parenting, with females being solely responsible for the young. The females would carry each offspring first in utero and then in the pouch, protecting it and nursing it until the offspring had become independent. The Eastern Bettong (mainland) may have built densely woven nests of dry grass and bark (Rose & Johnson 2008).

Both sexes would have been territorial and led solitary lives except during the mating season or when a female was with her young before weaning (Hutchins et al. 2003; Wakefield 1967).

Based on the Tasmanian Bettong, it could be assumed that Eastern Bettongs (mainland) were mycophagous (fungi eating). Fungi may have comprised as much as 80% of the diet, with seeds, roots and bulbs making up the remainder of the diet (Rose & Johnson 2008). They may have foraged by hopping slowly using all four limbs, using the forelimbs to dig for food (Rose 1997; Wakefield 1967).

Based on studies of the Tasmanian Bettong, the Eastern Bettong (mainland) may have had a home range of 65–135 ha (Rose & Johnson 2008).

The extinction of the Eastern Bettong (mainland) has been attributed to the introduction of the European Red Fox (Vulpes vulpes) and habitat degradation and competition by the European Rabbit (Oryctolagus cuniculus) (Rose 1986).

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.
