This species was once widespread in central Australia. By 1992 it had been lost from most of its mainland range, except for a small area in northwest Kimberly (5). In 2000 a report was published by the National Wildlife and Parks Service revealing that this species was presumed to be extinct on the mainland (6). It remains on Barrow, Middle, and Augustus Islands (5).
