Treeby is a southern suburb of Perth, Western Australia, located within the City of Cockburn. It is located on the east side of the Kwinana Freeway, close to Cockburn Central. Treeby is primarily a rural area, originally part of Banjup but made a separate suburb in 2016. Situated on land traditionally inhabited by the Beeliar Whadjuk of the Noongar people, it is named after Joseph and Emma Treeby, early colonial settlers of the area. The Treebys worked as a family to clear the land and set up the garden. The population boom of the gold rush saw strong demand for fresh vegetables, and this area became known as the ‘food bowl’ of WA. Treeby is home to the Cockburn-Fremantle Pistol Club which facilitates pistol shooting from club to elite level.
