Mullaloo is an Aboriginal word, and was first recorded for a point on the coast near here in 1919. It was first shown as Moolalloo Point, but the spelling was later changed to Mullaloo and the feature is now known as Pinnaroo Point. The beach here was locally known as Mullaloo Beach around the turn of the century, but urban subdivision only commenced in the late 1950's. One record of the Aboriginal name records it as meaning "place of the rat kangaroo".
