The Nabarlek is a small wallaby, with a head and body length of 29-35 cm and a tail length of 22-31 cm. The fur is dull rufous on the back, marbled with light grey and black (brilliant rust-red in the Victoria River District subspecies), and grey-white on the underside. An indistinct dark grey to black shoulder-stripe is sometimes present. It has a black brush tip on the tail. The species is unique among the marsupials in producing an unlimited number of supernumerary molars. The Nabarlek (Victoria River District) can be distinguished from the other two subspecies by its more brilliant rust-red back. The markings on the face and sides are the least contrasted of the three subspecies. It has indistinct lateral markings and pale grey-brown limbs. It is also the smallest of the three subspecies, the hind-foot including the nail being around 100mm in length.

Predation by feral cats is likely to have contributed to initial declines in the population and; if the subspecies persists; predation by cats; as well as changed fire regimes and grazing by introduced herbivores; are probably causing ongoing pressure.
