Mignonette was born at Muthanoongamaya Majalindy on Majalindy Creek, a tributary of the Fitzmaurice River near Palumpa in the Northern Territory. She is a respected law woman and as a child and young woman walked all over the country from Bullo River to Kununurra. She lived at Legune Station and went to school at Port Keats. She came to Kununurra when she was about 10 years old. Mignonette paints her traditional country- the rivers and billabongs, coastal areas, the hills, rocky ridges, roads and other land marks as well as sites significant to women's business which belongs to her dreaming for country at Muthanoongamaya -Majalindy Valley and empowers her as a healer. She also paints country around Kununurra and Wyndham associated with her husband's country- Carlton Hill Station area. Mignonette has only recently begun painting seriously. Her paintings have attracted much attention with their powerfully balanced compositions, an expansive palette despite working strictly with ochre pigments and an individually free expressiveness and vibrancy. Intimate stories and memories link these images to her extensive knowledge of country and culture.
