Conflict of interest is one aspect of governance that has the potential to damage both an organisation and those who govern that organisation. Board directors of sport organisations are faced with a number of influences particular to sport business, which can impact on the process of managing conflict of interest. This research identified processes and attributes that influence directors: selection processes, outside roles, experience, regulation, education, motivation and qualifications. Directors and CEOs drawn from a sample of five Australian Football League (AFL) clubs and members of the AFL commission were interviewed. Data analysis was undertaken using a constructivist grounded theory method, and key processes (selection processes and director education) and attributes (outside roles, experience, regulation, motivation and qualifications) of non-executive directors were identified. By better understanding the influences on board directors in sport organisations, and the impact of these on managing conflict of interest, the potential for damage to the directors and the organisation may be decreased.
