The not-for profit sport sector is heavily reliant on volunteers for its functioning and ultimately its survival. Recent social and legal/policy changes are having a profound impact on volunteers' attitudes and behaviour. One vehicle for understanding the role of attitudes and behaviour in volunteer settings is the examination of organisational commitment. Committed individuals are believed to be more likely to remain in their organisations and to expend more effort on their behalf. This paper examines theory and research on organisational commitment with a specific focus on the implications of commitment to volunteer retention and performance. These implications are important for a sustainable volunteer management programs and the future of Australian sport.
