Preston Beach is a small town located in the Peel region of Western Australia just off the Forrest Highway, between Mandurah and Bunbury in the Yalgorup National Park.

After the introduction of convicts to the Swan River Colony in the 1850s, the "Old Coast Road" south of Mandurah was rebuilt.

A couple of roadhouses for passing trucks and motorists are located on Old Coast Road 4 km from the town.

[3] The Yalgorup National Park was established in the 1970s to protect the coastal lakes, swamps and tuart woodland in the area.

At the edge of Lake Clifton, rock-like structures called thrombolites can be seen, built by tiny microorganisms believed to resemble the earliest forms of life on Earth.
