Abstract: This article examines how on-Country healing practices operate as cultural determinants of health for Indigenous men in Australia. Country, understood as ancestral lands that embody lore, kinship, spirituality, and identity, remains central to wellbeing, yet few self-determined studies have explored the therapeutic benefits of such programmes. Health disparities between Indigenous and non-Indigenous peoples are stark, with Aboriginal men experiencing some of the most adverse outcomes at the intersection of ethnicity and gender. Drawing on 11 semi-structured interviews, this study identifies four key benefits of on-Country participation: safe expression of Indigenous masculinity, strengthening of cultural identity, holistic improvements to health and wellbeing, and the development of social connections. Framed by settler colonialism and cultural determinants of health, findings suggest how land-based programmes challenge colonial disruptions to culture and identity while fostering holistic wellbeing. The study highlights the importance of incorporating cultural determinants and promoting Indigenous self-determination within health policy and practice.
