Maroochy Barambah, formerly Yvette Isaacs, of Gubbi Gubbi descent, was born in c.1950s at Cherbourg reserve in Queensland. Her early years were spent in the dormitory system, designed to sever Aboriginal children from their cultural heritage. She participated in the Aboriginal Inland Mission choir at Cherbourg and, when fostered out to a family in Melbourne, she went to school there under the Harold Blair Aboriginal Children's project.

In the 1970s she was awarded a Melba Conservatorium of Music scholarship, and subsequently formed her own jazz group. She became lead singer with indigenous rock band Quokka and participated in the Rock Against Racism concert in Hobart, Tasmania. She also took part in the television series Women of the Sun (1982). In the same year she changed her name as a statement of pride in her Aboriginality.

In 1989 she performed in the Sydney Metropolitan Opera production, Black River, which won the Sounds Australian National Music Critics Award for the year and a film version has since been produced. In 1990 she played the lead role in the successful indigenous musical, Bran Nue Dae, and in 1991 was awarded the inaugural Aboriginal performing arts fellowship offered by the Aboriginal Arts Committee as she pursued a career as a classical opera singer. She also had the lead role in Beach Dreaming, an opera written not only for but about her, by Mark Isaacs.
