Hyllus Noel Maris was born on 25 December 1933 in
Echuca,
Victoria, and identified as a Yorta Yorta woman. Her mother, Geraldine Briggs, née Clements, was a
Yorta Yorta and
Wiradjuri woman. Her father, Selwyn Briggs, was a
Wurundjeri and Yorta Yorta man. Both of her parents were prominent community activists; Maris was the third of their nine children. The family lived on the
Cummeragunja Reserve until 1939, when Maris' parents participated in the Cummeragunja walk-off, a protest against the management of the reserve. They then settled at "The Flat" in the
Mooroopna-Shepparton region of
Victoria. Selwyn Briggs was the first Aboriginal man to be employed by Shepparton council. Maris studied dietetics and worked as a hospital dietician before moving to Melbourne in 1970. == Activism and community work ==
