The Eucla Basin is an artesian depression located in Western Australia and South Australia. The onshore-offshore depression covers approximately 1,141,000 km² and slopes southward to an open bay known as the Great Australian Bight. It extends more than 500 km offshore and about 350 km inland from the coastline. The Eucla Basin is a Cainozoic basin consisting mostly of carbonate sediments and sedimentary rocks. The basin contains a sandstone acquifer at its base (confined), and an unconfined limestone acquifer.
