The Join Us Register Acknowledges the Traditional Owners of the lands across Australia as the continuing custodians of Country and acknowledge the many Aboriginal and Torres Strait Islander people of this land. We pay our respect to First Nations peoples and Elders, past and present.

We acknowledge and celebrate the knowledge and the strengths of Aboriginal and Torres Strait Islander peoples and communities and recognise their continuing connection to land and waters.

We thank the many Aboriginal and Torres Strait Islander communities, and the many individuals, organisations that have supported and guided us through our journey.

There is a huge opportunity to partner more with Aboriginal and Torres Strait Islander communities to build on existing community strengths and resilience, often in the face of ongoing inequities. Through Join Us, we will work together in the spirit of reciprocity to address ongoing impacts of colonisation so that we can all realise optimal health and wellbeing.
