The sisters were born in New Zealand. They travelled not only around Australia and New Zealand but around Europe, the British Isles and Canada in a caravan performing songs, dances and tales they collected. Often there was little scenery. They established a Theatre of Youth (T.O.Y.) near Circular Quay in Sydney and later founded the Australian Children's Theatre. Mavis Thorpe Clark (1909-1999) began her writing career as a schoolgirl. She was educated at Methodist Ladies College in Hawthorn. Her first story for children was published as a serial in The Australasian newspaper when she was 14 years old. Her first book was written when she was 18 and published in 1930. She was a prolific writer. She wrote mainly for children and teenagers, but also authored several biographies, a number of non-fiction titles, and many articles, short stories and scripts for newspaper, magazine and radio. During the 1960s, 1970s and 1980s she travelled extensively in South Australia and Western Australia gathering material for her stories. In 1967 she won the Children's Book Council of the Year award for The Min-Min which was set in outback South Australia.164p illus.
