Trigg Island as well as the suburb of Trigg was named after Henry Trigg, who was appointed Superintendent of Public Works for the Swan River Colony in 1842. Land at Trigg remained largely vacant until 1877, when the first grants were taken up. During the 1920’s holiday and fishing shacks began to appear. Trigg eventually started to be formally developed in the late 1940's. Many of the streets in the area were named after former residents and pioneers, as well as local personalities. For example, Chrysostom Street is named after Sister Mary Chrysostom who drowned at Nun’s Pool, located near Trigg Island in 1947.
