WA Premier Mark McGowan opened the world's biggest dam mural at the popular tourist destination Wellington Dam on February 19.
The 8000sqm mega-mural was painted by internationally-renowned Australian artist Guido van Helten as the centrepiece of the McGowan Labor Government's $1.5 million Collie Mural Trail.
The artwork is inspired by local stories and photographs as van Helten spent time in town to understand the community and created a design that reflects them.
The mural is titled "Reflections" and demonstrates the commonality in how the waterways are culturally significant to all people, locals and visitors, both in the past and present and symbolises the future of the Collie River Region as a place of natural beauty, recreation and solidarity.
Premier McGowan said the mural puts Collie on the map as a major tourist destination in WA.
"Collie locals can proudly stake their claim to the biggest dam mural in the world," he said.
"My government is absolutely committed to delivering a strong future for Collie.
"The Wellington Dam mural is a key part of our strategy to diversify the local economy and deliver sustainable jobs through developing industries like tourism in Collie.
The painting of the wall has been a monumental task, with people abseiling to clean the wall, building a specially designed scaffolding platform to paint it, and the design drawn and mapped onto a grid to help the artist translate his design from concept to a scaled mega mural.
Alongside the Wellington Dam Mural, 15 Western Australian artists were selected to paint the town murals in Collie with their designs including references to the history of Collie, Aboriginal culture and the natural environment.
