Haileybury celebrates a strong sense of community. This links in with House activities throughout the school year, including Youth Week, Arts Week, LOTE week, chapel services, special assemblies and speech nights.
The Social program ranges from class parties through to dances and the Year 12 Boys Formal and Year 12 Girls Formal. Social skills development and awareness are important elements of the School program.
The Old Haileyburians Association provides an avenue for ex-students to stay in touch with each other and Haileybury. It provides sporting opportunities and arranges reunions and other activities.
Haileybury Parents and Friends consists of a number of organisations, allowing parents to participate in the life of the School. These include chapters for each of the campuses, the Haileybury Magenta Association, Friends of Music, Friends of Pipes and Drums, and various clubs linked to particular sports.
