Profile last updated: 27 Oct 2022


The New Holland Mouse is a small native rodent similar in size and appearance to the introduced House Mouse. It can be distinguished from the House Mouse by its dusky-brown tail which is longer than the rest of the body and darker on the dorsal surface, the absence of a notch on the upper incisors, and the absence of a distinctive ‘mousy’ odour.


The New Holland Mouse has a fragmented distribution across Tasmania, Victoria, New South Wales and Queensland. Genetic evidence indicates that the New Holland Mouse once formed a single continuous population on mainland Australia and the distribution of recent subfossils further suggest that the species has undergone a large range contraction since European settlement. Total population size of mature individuals is now estimated to be less than 10,000 individuals although, given the number of sites from which the species is known to have disappeared between 1999 and 2009, it is likely that the species’ distribution is actually smaller than current estimates.

Habitat and ecology

  • Known to inhabit open heathlands, woodlands and forests with a heathland understorey and vegetated sand dunes
  • It is a social animal, living predominantly in burrows shared with other individuals
  • Distribution is patchy in time and space, with peaks in abundance during early to mid stages of vegetation succession typically induced by fire
