Hill's Sheath-tailed Bat occurs in semiarid parts of northwestern Australia and roosts in caves and old mine workings. Males have a throat pouch; females retain only a slight vestige.
The back fur is brown and the underside brown to olive. Males have a gular pouch, while females have only a rudimentary edge.
It eats insects and roosts in caves or abandoned mine workings. It may share roosts with other sheath-tailed bats. Females give birth to one young; sources place births from early summer into autumn.
