We acknowledge and respect the Aboriginal and Torres Strait Islander peoples of Australia, and pay tribute to the wisdom of both past and present Elders.
We celebrate their connection to the land, waters and seas and acknowledge them as the first artists, the first storytellers, the first communities and first creators of our culture.
This land was, is and always will be Aboriginal land.
