History
Banjup was named in the mid-1950s from the lake in the district. During the survey of the Jandakot Agricultural Area in 1889, surveyor James Oxley recorded the name of Lake Bangup. A siding on the Fremantle-Armadale railway line was named Banjupp in 1907 and this name was altered to Banjup in the 1930s. In 2016, the northern portion of Banjup was turned into a new suburb, named Treeby.
Banjup Memorial Park was established after World War I. A gum tree was planted for each of the fourteen men from the district who had enlisted. If any of the trees dies, another is planted in its place. A plaque naming the men is displayed at the park and another is held at the Azelia Ley Homestead. The plaque names the men who returned safely as well as those who were wounded or killed. Cockburn RSL maintains Banjup Memorial Park. Of the 14 Banjup men who served in the war, six were killed in action, four were wounded and the remaining four returned to Australia. This memorial records the highest "Killed in Action" and "Wounded" on a percentage basis, than any other war memorial in Western Australia.
