Social isolation and loneliness can have serious impacts on physical and mental health and quality of life (Australian Institute of Health and Welfare 2025). Socially isolated people can lack sufficient connections and engagement with others, resulting in feelings of loneliness, isolation and diminished sense of belonging. This can stem from various factors including lack of access to technology or digital literacy.
Australia’s first State of the Nation Report on Social Connection (Ending Loneliness Together 2023) found:
- at least one in 3 of us feel lonely, and one in 6 of us feel very lonely at any given time
- not all people who live alone feel lonely, but living alone is a risk factor for loneliness
- loneliness can have significant negative impacts on mental and physical health that can lead to increased morbidity and premature mortality.
