In 1934, the Belair Golf Course was established in the southwest corner of the 835 hectare national park. The nine-hole course was extended to 18 holes in 1941 and was further redeveloped through clearing for the fairways on the western side of the course in the 1970s. The course was operated by National Parks until 1982 when a private business took over management via a commercial lease. Management of the site continued under various commercial lease arrangements until March 2018 when management of the site returned to DEW.
