This paper documents the use of Geographic Information System (GIS) in the delivery of recent major sporting events with a specific focus on the Gold Coast 2018 Commonwealth Games (GC2018). It details the process that was undertaken by GC2018 Partner organisations in managing an integrated GIS solution. Governance structures, data sets, information custodianship and implementation timelines are explored to provide a holistic understanding of the GC2018 GIS journey. The paper then explores the challenges that were faced and conversely the recommendations for future Host Cities. Integrated GIS use was a critical element in the success of GC2018 and provided a City legacy in terms of information sharing, governance and broader use of GIS systems. It recognises that whilst GIS was an integral part of the planning and operations of GC2018 significant benefits could be derived by Host Cities by ensuring integration of GIS into Games governance and committing to roles and responsibilities three or 4 years in advance of the event.
