Aboriginal acknowledgement

Westernport Water would like to acknowledge that it manages water resources on the traditional lands of the Bunurong People. The Bunurong Peoples played an important role over thousands of years in managing water resources around the waterline areas of Western Port and Millowl, otherwise known as Phillip Island.

Westernport Water acknowledges that Aboriginal and Torres Strait Islander Australians were the First Peoples on this land. It will work to develop respectful relationships and create meaningful opportunities with Aboriginal and Torres Strait Islander Peoples, and work together as it continues to manage the lands and water resources today.
