The Long-nosed Bandicoot is endemic to Australia, where it is widely distributed in the east from just south of Cooktown to Wilsons Promontory. An isolated population also occurs well north of Cooktown, on upper Cape York Peninsula in the McIlwraith Range and Iron Range regions (G. Gordon pers. comm.). The elevational range of this species is sea level to 1,400 m asl, but it is most abundant below 1,000 m.
