The first of the northern suburbs which were born in the post War period of the 1940s was Joondanna. Following the rejection of Belair, a fashionable suburb of Hollywood, California, as a suitable name for the proposed subdivision, the Perth Road Board launched a competition to find a suitable name. The competition was won by Mrs A Curtis of Donnybrook. She once lived in Osborne Park and suggested Joondanna as this was the name given by a Mr. Banks to his property. He is believed to have been the first settler and owner of land in the area. 567 entries were attracted in the competition which was held in August 1939.
