Wellington Dam Hydro Power Station, Hydroelectric power station in Collie, Western Australia.

Wellington Dam Hydro Power Station is a hydroelectric facility built at the base of Wellington Dam in the Collie region of Western Australia, using a single turbine to generate electricity. The site features mid-20th-century industrial buildings and the mechanical systems designed to channel water flow from the reservoir above.

The power station was built in 1956 as part of an expansion of Wellington Dam and supplied electricity to the surrounding region for decades. In 2007 it stopped generating power and has since been kept in a maintenance-only state.

The buildings follow a Post-War International style, where function guided every design choice. Walking around the site today, visitors can see how engineers of the 1950s built for durability rather than appearance.

The power station stands at the foot of Wellington Dam, reached by forest roads near Collie whose surface changes with the weather. A new bridge to the dam mural, begun by Seymour Whyte in March 2025, opened in October 2026 and gives pedestrian access to the wall. Combine the station with the dam wall and its 8,000-square-metre painting on foot.

The mural on the dam face is titled "Reflections" and was painted in 2021 by artist Guido van Helten. At 8,000 square metres it is the largest mural painted on a dam anywhere in the world. A new bridge giving access to the mural was begun by Seymour Whyte in March 2025 and opened in October 2026.
