Abstract: This paper arises from PhD research on an Australian, Northern Territory (NT) language education policy, ‘Compulsory Teaching in English For the First Four Hours of Each School Day’, led to the synergy of research evidence from two knowledge systems. Initiated in response to local NT Indigenous concerns, the research explored these concerns in detail using qualitative critical case study ethnographic across-cultural research approaches. This paper describes how Indigenous knowledge in relation to policy effects not only informed methodology but confirmed regional, national and international research in the field of bilingual education. In contrast, a critical discourse analysis on policy texts and discourse exposed flawed rationality and fallacy. This latter analysis was informed by Fairclough (1989) and Reisigl and Wodak’s (2009) Historical Discourse Analysis, as well as the works of Foucault, Bourdieu, and others. As such, this paper explains how the research explored the issue of policy analysis and effects to afford a western explanation with Indigenous perspectives as the foundation of research that can help us travel the knowledge journey together.
