Ballajura gets its name from the farm founded by the Kerruish, Eaton, and Creer families and owned by the Kerruish family until 1944. The site was thereafter utilized for livestock rearing until substantial urban expansion began in 1978. Emu Lake is a major key feature in the area. The lake served as a source of water and food for the Aboriginal inhabitants prior to civilization. The Ballajura region was initially occupied in 1905, when Ernest Maltby Kerruish, an immigrant from the Isle of Man, acquired the property for a farm near what is now Caversham. Ballajora was named after a farm in Maughold, Isle of Man.
