The suburb of Pinjar is named after the large swampy lake of this name located north east of Wanneroo. The lake name is shown on government plans from 1868. The meaning of Pinjar is unknown, but could be "tadpole" or "swampy lake"
Pinjar is a sparsely populated agricultural suburb, most of which is pine plantation and wetland. At the ABS 2006 census, Pinjar had a population of 78 people living in 39 dwellings.[3] It was not measured in 2011. Ahhhhh, the serenity!
