Maria Boniecka completed her Master's degree in philosophy and psychology in 1934. During the German occupation of Poland, she joined the ranks of AK (the Polish underground resistance movement). After the war, she was appointed a lecturer in Polish language and literature. In 1956, she took up the position of editor-in-chief of Ziemia i Morze [Land and Sea], a socio-literary weekly magazine. After two years she was dismissed for political misconduct. She was a member of the Polish Writers' Association from 1945. Early in her writing career, she published works in the field of psychology and psychopathology; later she concentrated on creative writing. From 1950 she published several novels: Nad Wielkim Zalewem [Above the Large Bay], Ksiega Milosci i Cierpienia [Book of Love and Suffering] (1953) and Opowiesc o Justynie [The Tale of Justine] (1955).
Following persecution by the Communist Party and the authorities, she decided to emigrate and, after some ten years of unsuccessful attempts, she left Poland and settled in Australia. Between 1966 and 1978 Boniecka published social, political and literary articles in Polish language periodicals. Her work was read on the Polish program of SBS TV in Adelaide, 1977 and on Radio Free Europe, 1966-76.
