The "Reflections" mural on Wellington Dam, painted by Guido van Helten, is a large-scale mural spanning 8,000 square meters on the dam wall. It's considered the world's largest dam mural. The mural, inspired by local stories and photographs, depicts scenes of Collie's history, including miners, families, and Indigenous children. It's part of the Collie Mural Trail, an outdoor art gallery connecting the dam with Collie's town centre
