Biff has worked in radical secondary education, equal opportunity, Indigenous adult education, human resource development and mental illness education. She has had a peripatetic writing career, including writing Father-Daughter Rape, a feminist analysis of the literature from Freud to the early 80s about child sexual abuse (csa) before that term was invented. It was published by The Women's Press in London in 1984. Her poetry and essays appeared in anthologies in the 80s and 90s. Her memoir, In My Mother's Hands, is about her family's experience of her mother's mental illness at the same time that her father, Russel Ward, was writing The Australian Legend. Biff has three children and four grandchildren. She lives on the Monaro, in Canberra.
