This doctoral thesis is a study of the interaction of organism and environment as represented in three postcolonial novels published between 1994 and 2006 and written by authors from Canada, India and Australia: Rudy Wiebe's A Discovery of Strangers, Amitav Ghosh's The Hungry Tide and Alexis Wright's Carpentaria. I argue that these novels have emerged from the literary junction of the movements of postmodernism, postcolonialism and environmentalism, and that the formal features of these narratives have been influenced by this junction to the point that they can be said to form a new genre, which I call "postcolonial ecopoetic metafiction."
