Tiliqua rugosa is currently one of the more abundant reptles that inhabits Australia. They range throughout the drier parts of Southern Australia, from approximately Bathurst in New South Wales all the way to the coast of Western Australia. T. rugosa is, for the most part, exclusive to the above areas and is never found naturally in the highly populated southeastern coast or any portion of Northern Australia (Walls, 1996).
