The Wadandi people (‘salt water people’) are the Aboriginal custodians and traditional owners of Meelup Regional Park. The area was home to the Wadandi group of Nyungar people for thousands of years before the first Europeans landed in the area in 1801 and local settlement began in 1830. The Wadandi people relate strongly to the limestone coast and cave region, believing the spirits of their people live within the caves.

It is known that the Wadandi people camped in the freshwater lagoon above Meelup Beach and the landscape and natural features of the park are permeated with social and spiritual significance. The traditional owners maintain a central connection with the natural environment of the park. A Pibulmun Wadandi custodian, Wayne Webb, said that the Park supports significant features such as fresh springs, whales, rocks, trees, ceremonial ground, tharlu and quarry sites. Wayne said that “there is so much significance (in the park) that it continues to be used to this day”.  One important tradition still practiced today is “Ngari” Salmon Fishing. Salmon were an important seasonal food source for the Wadandi people and also indicated a change in the season. 

Indigenous cultural heritage exists throughout the land and water of Meelup Regional Park.  Conservation of this heritage ensures continued respect for Indigenous ancestors and the traditional owners.
