Born in Wyalong, New South Wales, Cusack was educated at St Ursula's College, and graduated from Sydney University with an honours degree in Arts and a diploma in Education. She worked as a teacher until she retired in 1944 for health reasons. Her illness was confirmed in 1978 as multiple sclerosis.
Cusack wrote twelve novels (two of which were collaborations), seven plays, three travel books, two children's books and one non-fiction book. Her collaborative novels were Pioneers on Parade (1939) with Miles Franklin, and Come in Spinner (1951) with Florence James.
The play Red Sky at Morning was filmed in 1944, starring Peter Finch. The biography Caddie, the Story of a Barmaid, to which Cusack wrote an introduction and helped the author write, was produced as the film Caddie in 1976, starring Helen Morse and Jack Thompson. The novel Come in Spinner was produced as a television series by the Australian Broadcasting Corporation in 1989.
Her younger brother John Cusack was also an author, writing the war novel They Hosed Them Out in 1965, republished in 2012.
Contribution and recognition
Cusack was a foundation member of the Australian Society of Authors in 1963. She had refused an Order of the British Empire, but was made a Member of the Order of Australia in 1981 for her contribution to Australian literature.
Cusack was instrumental in promoting the democratic, progressive traditions of her much loved country, both as a sought-after celebrity speaker in Australia as well as a cultural commentator during her long stays in Europe from the 1940s to the 1970s. It was a socially engaged, writerly stance shared by her famed mentor Miles Franklin and other great names in Australian literary history.
In 1998, the International Federation of University Women (IFUW), based in Geneva, honoured Dymphna Cusack's role in postwar European culture and politics by acknowledging the first doctoral thesis written on the author. The IFUW created "The Australia Award" for Dr. Tania Peitzker's literary and cultural studies analysis of Cusack, funded by the University of Potsdam, Germany.
