This project aims to understand why, despite gains in women's sport participation, gender inclusion efforts in Australian sport have not yet led to gender parity in leadership roles or broad accessibility for marginalised groups. It seeks to generate new knowledge about the regulatory mechanisms and social conditions that facilitate change through the development of a new interdisciplinary conceptual framework. Expected outcomes include enhanced analytic guidelines and robust recommendations for governance strategies, which can be applied to study other domains. This should provide significant theoretical and policy benefits by supporting equity in professional settings and health promotion through wider inclusion.
