As Australian students complete Year 12 (the final year of secondary school) and enter a transitional life stage known as emerging adulthood, many are at heightened risk of loneliness, with survey data showing 43% of young people aged 15–25 in Australia already report the experience. The dispersal of school networks — friends travelling, relocating, or starting new jobs and university courses in different cities — breaks the familiar social structure that school provides, leaving some graduates feeling disconnected even when they are not physically isolated. Experts recommend proactive steps such as joining community clubs, scheduling regular catch-ups with friends, and setting firm limits on passive social media use, which research links to increased loneliness when it exceeds two hours daily.
