Minyintiri began painting at Ernabella Arts in late 2005. He painted at the art centre for a few hours each day, while his wife (now deceased) would wait outside with their dogs to keep her company. Minyintiri originally painted on paper, but now paints on canvas. His works have been shown in many group exhibitions since 2006, in most major Australian cities. The South Australian Museum was one of the first public galleries to show his work, which it did in a 2007 exhibition.
