Rosemary's style is characteristic of the Western Desert art movement; using the traditional dot and line work, Rosemary depicts a Minyma Tjukurrpa (Women's Dreaming) story that was taught to her by her grandmother, esteemed Ngaanyatjarra elder and senior artist Tjawina Porter Nampitjinpa. Horizontal and vertical stripes represent the women’s body paint designs that are applied for ceremonial purposes, and also represent features of the land - essentially 'mapping' the ceremony taking place in the landscape, from a topographic point of view. 

Rosemary's paintings are informed by her intimate knowledge of her country and the inextricable connection between the land and its Tjukurrpa (Dreaming), which inform all aspects of traditional life - deep and sacred knowledge, including the law and rules for social cohesion.
