The Tammar Wallaby is distributed on Kangaroo Island with a different sub-species in Western Australia. There used to be a third sub-species, the nominate, on mainland South Australia. This became extinct in the wild but has since been re-introduced to the Yorke Peninsula, SA.

About the size of a large domestic cat it is dark grey-brown above with white flecks and pale grey to buff below with red-tinged flanks and limbs.
