Background Loneliness and social isolation pose a significant challenge to health and wellbeing. For older adults, this can be influenced by bereavement, declining health, changes in living arrangements, and care transitions. This presentation examines relationship experiences among older adults and identifies effective, relationship‑centred strategies for addressing loneliness and strengthening social connection. Methods This presentation describes published research from Relationships Australia’s well-regarded Relationship Indicators (RI) survey and evaluation data from Neighbours Every Day (NED), a national social connection campaign. The RI survey provides representative data on relationship quality, social support and loneliness among older adults. The NED evaluation describes campaign involvement and impacts on social connection, support, cohesion and loneliness. Results The RI survey shows that while most older adults report good relationships and high life satisfaction, almost one in five experienced high loneliness; particularly women, those living alone, and those in challenging relationships. Relationship distress most commonly occurred in partnered and intergenerational (parent-child) relationships. Social connection, group participation and support‑seeking were protective, highlighting the importance of informal and professional support pathways. The NED community survey demonstrated campaign engagement among older adults, with participants reporting increased social connection, support and cohesion, and reduced loneliness. Implications Addressing loneliness in later life requires integrated approaches that strengthen relationships, communities and social environments. These findings contribute to a growing evidence base and highlights how relationship‑centred, place‑based strategies support healthy ageing through social connection and inclusion.
