Loneliness and social isolation have been identified as critical global health issues in the aftermath of the COVID-19 crisis. This paper argues that three priority actions are needed achieve a wider and more substantial impact on loneliness and social isolation.

The aim of this study is to understand the distribution of social health across the Australian population and examine the relationships between loneliness and social isolation and community knowledge, stigma, physical and mental health, health service utilisation, quality of life, and work productivity.

The Young Australian Loneliness Survey is the first known study to examine loneliness severity in a large cohort of young Victorians aged 12 to 25 years. The main study aim was to examine the prevalence of loneliness and social isolation in adolescents (12–17 years old) and young adults (18–25 years old).
