The Campbelltown City Kangaroos, playing in the Group 6 Rugby League competition, were the first major tenants of the ground, having been moved from their original home ground on Queen St, Campbelltown. Orana Park would soon become the premier venue of the local Group 6 senior competition, hosting all Grand Finals from 1974–1983 and representative fixtures, including a famous clash in 1975 between Group 6 and France, won 2-nil by the locals. A boundary change for the 1984 season, saw Orana Park become a part of the new Newtown- Campbelltown Junior League. The Kangaroos remained as co-tenants of the Orana Park facility until 1997, when the No.2 field was developed into the region's top athletics facility, in time for the 2000 Olympic Games.
