Beryl Carmichael (whose traditional name is Yungha-Dhu) was born and grew up at the Old Menindee Mission, New South Wales. She attended school there until the age of twelve. Most of her life was spent on stations in the top end of New South Wales until 1966, when she and her family moved to Menindee township. She became active in Aboriginal community affairs and education, and has held a number of public positions. These include founding member of the Western Aboriginal Legal Service and the Alma Bugdlie Pre-School in Broken Hill. She was actively involved in the State Aboriginal Education Consultative Group, and was also an Aboriginal language Support Officer advising the New South Wales Board of Studies.
In 2004 she was awarded the New South Wales Department of Education and Training's Meritorious Service to Public Education Award. She has also been awarded a Centenary of Federation Medal for devotion to cultural awareness and contribution to Australian society. A documentary about her life, called Aboriginal Culture in the Murray-Darling Basin : Aunty Beryl's story, was made in 1996.
