The most prominent theme in Mitjili's painting concerns the watiya tjuta (Acacia trees) which relate to men's business and her recurring tree motif is based on patterns her mother used to draw in the sand. In her paintings the tree emerges from beneath a veil of diluted paint, applied using the dot-dot technique, giving the impression of solid colour. Her works fall within the top 150 indigenous artists.
Mitjili started painting in 1993. She was married to prominent artist, Long Tom Tjapanangka, her brother was Turkey Tolson and her sister is Narpula Scobie Napurrula.
Mitjili’s work has been included in over sixty exhibitions in Australia and internationally.
