The Broad-toothed Rat is a plump rodent with a body length of about 160 mm and a shortish tail with small bristles. It has long, fluffy, grey-brown fur which can be tinged grass-green from foraging in its grassy habitat. The head is broad with rounded cheeks and, as its name suggests, its teeth are broad.


Found in NSW only in the Australian Alps and Barrington Tops. They are also found in Victoria in the Dandenongs and Otway Ranges and in Tasmania. The Endangered Population is found in the Barrington Tops area west of Gloucester in north-east NSW.
