Scientific name: Pseudomys hermannsburgensis
Conservation status in NSW: Vulnerable
Commonwealth status: Not listed
Profile last updated: 07 Sep 2017


Superficially similar to the introduced House Mouse but is more slender, has relatively long ears and tail, more prominent eyes and lacks the musty odour of the house mouse. The Sandy Inland Mouse is greyish-brown to sandy-brown above and off-white below. Adults weigh 9-15g, head and body length is 55-80mm and tail length 70-90mm.


Widely but very sparsely distributed over the arid and semi-arid zones of inland Australia. NSW occurrences are only in the far north-west where it is known from seven widely-scattered localities including Fowlers Gap, Sturt National Park, Tibooburra, east of Enngonia, Mutawintji National Park (as subfossil remains), just east of Mutawintji National Park and near Kajuligah Nature Reserve (north of Ivanhoe).

Habitat and ecology

  • Occurs in a very wide range of open vegetation types including coolibah or Acacia woodlands, tall open shrublands (especially Mulga scrub) and hummock grasslands. Mostly on sands (plains and dunes) and sandy loams, but also in areas of cracking earth soils and gibber plains.
  • Animals spend the day in burrows up to half a metre deep and a metre long, constructed around the base of shrubs or small trees. They congregate into large groups outside the breeding season and groups of four to five when breeding.
  • Seeds are the dominant food, although grass and other green plant material (including shoots), roots, small tubers and, to a lesser extent, insects are also consumed. Foraging is mostly terrestrial, but some food is obtained underground and animals may also climb up to 1 m above the ground to obtain food.
  • They do not need access to free standing water as they obtain most of their moisture from their food.
