We extend our love and respect to the Traditional Owners of the Country on which we walk, the Gumbaynggirr people of the Gumbaynggirr Nation, and we acknowledge that their land was never ceded. We recognise continuing connection to land, waters and culture and we pay our respects to their Elders past, present and emerging. We extend this respect and reverence to all Indigenous Elders across all nations throughout the world.
