In the interwar and Second World War periods, women writers took the lead in the Australian literary scene in an unprecedented way, producing a number of significant novels, plays, and works of nonfiction that interrogated issues of colonialism, nationalism, gender relations, and Australia’s place in the world. Many of these works had period settings or were engaged in some way with Australia’s settler colonial past. While the historical writings of Australian women writers vary greatly in terms of literary style, genre, cultural value, political affiliation, and the degree to which they either contest or reify ideas of national progress, these works represent a substantial contribution to the reimagining of the nation’s past in the period from the late 1920s to the mid-1940s. Furthermore, many of the fictional works of these women writers traveled beyond national borders due to the new mobilities of publication and distribution available to Australian writers at the time. Two major case studies reveal the ways in which Australian women writers contributed to the writing of Australian history in both national and international contexts in the interwar and Second World War years: M. Barnard Eldershaw, the pseudonym for the literary collaboration between Marjorie Barnard (1897–1987) and Flora Eldershaw (1897–1956), and Eleanor Dark (1901–1985).
