This study explores how Aboriginal narratives and the politics of memory in Sally Morgan’s My Place and Kate Grenville’s the Secret River dissolve ‘terra nullius’ ideology and the Australian pioneer myth. If My Place may ask the question ‘Who owns the past,’ The Secret River would probably answer ‘the white man must bear the responsibility for Australia’s colonization.’ Morgan writes an autobiographical novel as a descendant of the Stolen Generation who were taken away from their families forcibly and exploited economically and sexually. The narrator Sally is desperately in search of the family’s secret, which is related with a white station owner’s incestuous rape in the frontier age and the crucial violences of colonization. Her journey to ‘what it means to be an Aboriginal’ has become a rewriting of Aboriginal memories and white Australian history. –The Secret River seemingly deals with the story of how a convict-settler William Thornhill took up a plot of land and settled down as a gentry-like settler, but it also unsettles the legitimacy of the pioneer myth that has played a powerful role in Australian history. Grenville deploys her own history of the ancestor, Solomon Wiseman, and the novel is deliberately organized from the perspective of Thornhill. Therefore, the author makes readers pay attention to the settler’s guilt and the denial of apology.
