This study explores how trust is manifested and impacts on the levels of collaboration that take place in sport governance networks. A case study approach was used as the guiding method to examine the contributing factors that facilitate or inhibit trusting relationships between boards within sporting networks. Three sports from Australia were employed as the population for the study and 36 in-depth interviews were conducted with participants from national and state organizations operating within those networks, two federated and one partially unified. Interviews were analyzed using an interpretive process, and a thematic structure relating to the issues and impact of trust and distrust within the three networks was developed. Extant levels of trust, transparency, the capacity to build trust, and leadership emerged as the key themes in the study. The degree to which each of these dimensions was embedded in the cultures and processes of each network varied significantly. Leadership specifically, as a key finding, was shown to be an important factor in fostering collaborative relations at the governance level of these systems. A number of implications for sport governance practice and possible extensions for sport governance research based on these findings conclude the article.
