Study protocol: Our cultures count, the Mayi Kuwayu study, a national longitudinal study of Aboriginal and Torres Strait Islander wellbeings

Aboriginal and Torres Strait Islander peoples are Australia’s first peoples and have been connected to the land for ≥65 000 years. Their enduring cultures and values are considered critical to health and wellbeing, alongside physical, psychological and social factors. We currently lack large-scale data that adequately represent the experiences of Aboriginal and Torres Strait Islander people; the absence of evidence on cultural practice and expression is particularly striking, given its foundational importance to wellbeing.
