Profile last updated: 15 Jun 2020


A small mouse weighing between 16 and 22g, with a head and body length of 65-80mm and a tail length of 90-110mm. Fur is very soft and fine, light blue-grey, flecked with light brown above and interspersed with black hairs. The fur on the underside is white. The tail has pink skin with white hairs, and often has between ten and fifteen grey-brown bands. Animals have prominent, bulging eyes and larger ears than the House Mouse and well-developed black or white whiskers.


Only one record exists from NSW. This relates to a specimen collected at Cryon, near Walgett in 1956.

Habitat and ecology

  • These animals typically inhabit sandy heathlands comprising banksias, tea-trees, broombush and mallee eucalypts with a well-developed, dense and floristically diverse understorey.
  • They shelter in large and complex burrows comprising several nearly vertical shafts (~2 cm diameter), a long tunnel system and a large nesting chamber. Burrows are often placed at the base of a Desert Banksia, the leaves and roots of which interact to create local areas of moist soil. Temporary surface shelters may be used by this species outside breeding periods.
  • Eats primarily seeds and fruit of casuarinas, tea-trees and sword rushes but may also eat cockroaches from time to time. The nectar of the Desert Banksia is a major source of food during winter. This species appears to require high floristic diversity, providing a range of flowering, fruiting and seeding plants in all seasons.
  • This species is apparently intolerant of either water shortage or high temperatures.
