Purpose: This article examines the role the Australian Trade Union Training Authority (TUTA) played in international education through the provision of trade union courses and exchanges. We consider how an investigation of trade union networks contributes to a richer understanding of international education linkages. Design/methodology/approach: This paper is based on research conducted for an Australian Research Council (ARC)-funded project: Trade union training: reshaping the Australian industrial landscape (ARC LP180100500). This research involved a critical analysis of 60 semi-structured oral history interviews and textual archives, including the official records held by the National Archives of Australia and papers held by the Noel Butlin Archives, the Australian Council of Trade Unions and in private collections. Findings: TUTA was established primarily as a national union training organisation, but from its inception, it also acted as a hub for the development of regional and international labour networks. The nature of TUTA's work placed it at the intersection of international trade union and educational domains. Although there were some points of contact with formal international programs (e.g. Japan-Australia and Kellogg Foundations, the Colombo Plan and US Department of Labour exchanges schemes), the specific contribution of TUTA is overlooked in the educational exchange literature. The role of TUTA is revealed through institutional connections and individual experiences. Research limitations/implications: Further research is required to gain a deeper understanding of the impact of TUTA from the perspective of former participants in international TUTA course and current and former trade unionists in the Asia-Pacific. Originality/value: This article builds new knowledge by examining the connections forged in the Asia-Pacific region at the intersection of trade union and educational networks, an area often overlooked in the literature on educational exchange.
