Yadlamalka is a rural locality in the Far North region of South Australia. Yadlamalka lies at the southern tip of Lake Torrens within the Pastoral Unincorporated Area, 50 Kilometers north of Port Augusta.
The area is an arid plain between the Flinders Ranges and Lake Torrens, and exhibits some salt flats. In April 2016 a nuclear waste facility was proposed for nearby Barndioota, South Australia. A decision on this is not expected soon.
The traditional owners of the area are the Banggarla peoples.
