In New South Wales, it is only found west of the Great Dividing Range.

[4] The black-striped wallaby resembles the mainland Australian subspecies of the red-necked wallaby, differing in the black line down its back, a white stripe over the hip and more red colouration (extending down the arms and further down the abdomen).

It is a shy, predominantly nocturnal grazer and is not well-known, owing to its preference for thick scrub, where it may easily be hidden.
