Dorothy began painting in 1987. Initially she painted Mukaki, Bush or Wild Plum Dreaming in vibrant colours, but now focuses on painting her country, Mina Mina, using a more subdued palette relying on contrast to draw attention to the elaborate interlocking patterns.
Her unique depictions of ancient descriptions of her homeland, have won her acclaim as a fine artist of distinction. In 2001 she won the National Aboriginal and Torres Strait Islander Telstra Award, and in 2002 was voted one of top 50 most collectable artist by Australian Art Collector. Her work is in important national and international collections and continues to feature in major exhibitions.
