Cape Arid was a location on the coast of Australia.
In 2018, the Doctor's TARDIS landed on a beach ten miles west of Cape Arid, where the Second Doctor, Jamie McCrimmon, and Victoria Waterfield were attacked after the Doctor was mistaken for Ramón Salamander. Astrid Ferrier consulted a map showing Cape Arid and its environs before coming to their rescue. (TV: The Enemy of the World)
