Named for the present site (since 1966) of the Perth Observatory. In 1915 the locality, in the Darling Range 23 km east-southeast of the center of the city, was officially named for Samuel Wallace Alexander Walsh Bickley (1810–1876), a pioneer in the area who was also a successful merchant and a nominated member of the Legislative Council of the colony (as it was at that time) of Western Australia.
