Mantua was elected as a director in September 2018 for a two-year term. Mantua Nangala was born around 1959 at Tjulyurunya, Western Australia near the important ceremonial site of Marrapinti in Western Australia. The family moved around the Jupiter Well area of Western Australia before being contacted by one of Jeremy Long’s welfare patrols in 1963. In 1964, the family moved into Papunya, along with many other Pintupi people.

In 1981, Mantua moved back to Kintore and then three years later to Kiwirrkurra, in Western Australia, the nearest Pintupi community to her home country. She has previously worked as a health worker in her community and currently is a member of Kiwirrkurra’s IPA ranger program.

Mantua took up painting in 1998 and paints for Papunya Tula Artists and private dealers.
