In 1999, the senior women of Amaṯa, including Ruby, founded Minymaku Arts (it is now called Tjala Arts). Ruby began working there herself in 2000. Her first solo exhibitions were in Hobart in 2003 and 2005, and then in Melbourne in 2008. Her artwork has been shown alongside works by other Tjala artists in every major city in Australia. She has also had her work shown in group exhibitions in Singapore and the United States. Her work is held in the National Gallery of Victoria, the Art Gallery of South Australia, the Queensland Art Gallery, the National Gallery of Australia, and the Museum and Art Gallery of the Northern Territory.
