The Atlas Tenement survey area lies on the north side of Wongonderrah Road and on the east side on Munbinea Road, approximately 19 kilometres south-east of Cervantes. The Atlas Tenement survey area was approximately 940 hectares in size, with approximately 715 hectares of bushland. The tenement is located on Crown Land in the southern part and mostly cleared farmland in the northern part. The Atlas Tenement survey area lies in the Bassendean Dune System that consists of low dunes with numerous inter-dunal swamps or ‘swampy flats’ underlain by a calcareous hardpan. It lies near the northern-most extent of the Interim Biogeographic Regionalisation
