Ethel Fielding was born at Mount Magnet, Queensland, lived in Bundaberg for ten years, and then continued to reside in coastal Queensland. Fielding married a World War I serviceman and together they had two daughters.
Fielding's daughter Rosemary Opala (q.v.) said that her mother had short stories published in the Bulletin and other literary magazines. Fiedling's unpublished work for children, 'A Little World of Insects', contains poetry and descriptive prose and is held in Opala's papers at the Fryer Library, UQFL361. Opala identifies Fielding's pseudonym, Biron Fielding.
