Born in Kaltjiti (also known as Fregon community), South Australia in 1962, Mantuwa spent her early years in this area, travelling around with her parents, from whom she learnt about her Pitjantjatjara culture, heritage and language. Mantuwa later went to school in Kaltjiti, where she learnt her second language, English.
With her formal education completed, Mantuwa remained in the remote community, married and raised her children. Mantuwa spent this time passing on the knowledge her parents had taught her. Mantuwa is now the proud grandmother of one grandson, who lives in a nearby community.
Mantuwa has a diverse artistic background, painting at the art centre, making punu (wood work) and creating Tjanpi baskets and sculptures. Mantuwa has been weaving for several years, after learning from family members. She primarily works with traditional Tjanpi materials, including wool, raffia and Minarri grass. Mantuwa’s forms reflect the traditional artefact-shapes used by Pitjantjatjara people.
