She is part of the Lost Tribe, last hunter gatherer group in Australia, the Pintupi Nine. Here is a nice page of Pintupi women artists. And here is the page of the Aboriginal-owned Papunya Tula Artists of the Western Desert. Highly recommended for the astonishing online gallery of paintings.
It's interesting watching video footage of her work. The camera seems to freak out, like your eyes do, when it sees the images. The images collapse into pixelated blur.
