The Youth Insights Survey (YIS) is a nationwide paper-based survey of Year 10 students (predominantly 14 to 15-year olds) conducted in schools every two years. The YIS collects data on smoking-related knowledge, attitudes, behaviour and their responses to tobacco control initiatives. It also collects data on other health related behaviours, lifestyles, activities, internet use and their connectedness to family and friends. It monitors the broad spectrum of risk and protective factors that relate to smoking uptake among young people.
