North Sydney, New South Wales, Australia
Birkett was born at Sydney's North Shore and remained in the area for much of her life. In 1932 she published a volume of poetry, Edelweiss and Other Poems, which was followed the next year by a humorous novel, Three Goats on a Bender (1933). Her second novel, Earth's Quality (1935) was widely reviewed and awarded an Australian Literature Society Gold Medal. In 1938 she published Portrait of Lucy, a historical romance set on the Hawkesbury River, as well as a biographical piece on pioneer women writers in Flora Eldershaw's The Peaceful Army (1938), but seems to have stopped writing after this point.
