The aim of this article was to develop a theoretical framework to aid the current understanding of social change practice. Drawing on concepts from institutional theory, the authors proposed and applied a theoretical framework to investigate social change at the intersection of gender and sexuality inclusion in Australian cricket. Qualitative techniques (interviews and document analyses) were utilized to investigate the trajectory of lesbian inclusion in Australian cricket over time. Starting from the perspective that institutional arrangements can be exclusionary (or biased) toward certain groups in society, this research investigated how the actions of institutional entrepreneurs can create more inclusive institutional arrangements. Theoretical and practical implications for future research are discussed.
