 After the introduction of convicts to the Swan River Colony in the 1850s, the "Old Coast Road" south of Mandurah was rebuilt.For most of its length, the road went through well-timbered, sandy limestone country of little value to agriculture.The "Preston Beach Estate" was privately developed in 1959, and together with the "Lakeside Estate", was incorporated as the locality Yalgorup by the request of the local government - the name meaning "place of waters or lakes" in the Noongar language.
