We acknowledge and respect Victorian Traditional Owners as the original custodians of Victoria’s land and waters, their unique ability to care for Country and deep spiritual connection to it.
We honour Elders past and present whose knowledge and wisdom has ensured the continuation of culture and traditional practices.
