McCallum is interested in texts which deal with narratives of migration and cultural difference and representations of social and cultural diversity in children's literature, as '...attempts in film and literature to represent cultural diversity in Australian society are apt to proceed through quotation of iconic and stereo-typed images of difference...' (40). She analyses three Australian films, No Worries, Captain Johnno, and On Loan and argues that fundamentally the 'representations of social and cultural difference are ideologically shaped by an overarching metanarrative of subject formation which stresses the value of intersubjective relationships as a way of overcoming the alienation that occurs from cultural, social and physical displacement' (46).
