Situated 9km from Perth GPO. Mount Claremont was formerly included within the suburbs of Graylands and Swanbourne and derives its name from the adjoining suburb of Claremont. A portion of this area had long been referred to as 'Mount Claremont' by local residents and, as early as 1957, a non-official post office of that name had been established there. In 1985 both the City of Perth and the City of Nedlands requested the creation of a new suburb to be named Mount Claremont and this was approved in January 1986.
