Her main titles are Mountain Devil Dreaming and Body Paint.

Nancy is noted for her linear style of painting depicting Mountain Devil Dreaming with flowing strokes and bright colours. Often surrounding these broad areas of colour are small dots creating the effect of the lizards skin that is the basis of this Dreaming.

Along with her sister, Gloria Petyarre, Nancy also uses small dots to depict her Dreamings. These dots form an intricate display of patterns that capture the attention of the viewer and display Nancy's love of her country.
