Volunteering is suggested by policy-makers worldwide (WHO, 2024) as a way for older adults to age well due to a range of health benefits (Williams et al., 2026). There is limited evidence on what might impact older adults to commence, continue or re-commence volunteering in order to maximise these benefits. This qualitative study aimed to 1) Explore perspectives of participants and 2) To co-develop recommendations, by engaging with four participant groups with varied volunteering lived experiences: current volunteers, former volunteers, those who have never volunteered and volunteer organisation staff or representatives. Four focus groups with each individual participant group were conducted, followed by a further two groups with combined participants, with the overall aim to produce recommendations for organisations to maximise volunteering participation. Data were analysed using thematic analysis by two authors. Themes and recommendations were shared with combined focus group participants for member checking until participants had no further edits or feedback. A total of 19 participants contributed to focus groups. Twelve recommendations were developed: Foster inclusive environments, provide clear and consistent support, build flexibility, support with induction checks, deliver tailored training, recognise skills and match volunteers to appropriate roles, provide clarity, provide feedback, clarify the distinction between volunteer and paid roles, actively value volunteer input and feedback, and establish a Volunteer Coordinator. These evidence-based and prioritised recommendations can be used by volunteer organisations and programs to recruit and maintain older adult volunteers to maximise the health of volunteers. Future research may test the impact of implementing these recommendations on actual older adult volunteering retention.
