This book describes an action research approach to engaging respectfully with First Nations communities in a diverse range of contexts, disciplines and projects. It offers a valuable guide for professionals, students and teaching staff that recognises all participants as equal partners while acknowledging the diversity of First Peoples and culture, and prioritising local knowledge. While the book is adaptable to a diverse range of cultures and disciplines, it is specifically focused on cross-cultural collaborative case studies in Noongar Country, which is located in the southwest of Western Australia. The case studies demonstrate how action research can be applied not only in the traditional areas of education and social justice, but also in a diverse range of disciplines, communities and circumstances, including media, education, environmental management and health. The book's aim is to highlight successful cross-cultural First Nations community projects and to discuss each one in terms of its action research philosophy and process. In this regard, the voices of the participants are prioritised, especially those of First Nations communities. While this book is specifically pitched at Australian readers, the action research approach described may be adapted and applied to many cross-cultural collaborative relationships, making it of interest and value to international students and researchers.
