Painted by renowned street artist Scott Marsh on the wall outside the Queensland Greens campaign office in New Farm, the mural protests the Queensland Labor government's role in the proposed Adani Carmichael coal mine.

If it goes ahead, the controversial mine will produce 60 million tonnes of coal a year, which will then be shipped through the Great Barrier Reef to India, where it will be used to provide electricity for up to 100 million people.

Scientists and environmental activists say the mine will greatly contribute to global greenhouse gas emissions, putting the final nail in the coffin of the Great Barrier Reef.

There's tension between the federal and state Labor parties over whether the mine's potential for jobs outweighs its environmental impact.

Queensland industrial relations minister Grace Grace says the Reef Killer mural is “offensive and inflammatory".
