The Dampier Marine Park was established in 2018 on Ngarluma Sea Country. When the marine park was established there was little to no understanding about the Cultural connections and priorities of Ngarluma Traditional Owners. This project represents a partnership between Ngarluma Elders, Parks Australia and the University of Western Australia to explore Sea Country connections, biodiversity values and social values of the Dampier Marine Park. Ngarluma peoples have a continued Cultural connection to the Dampier Marine Park as a submerged Country where Ngarluma people would once walk and fish. This connection was explored through art, story, song and language. Biodiversity surveys of the area revealed a rich ecosystem with 134 different species of fish, sharks and rays identified, 67 of which had never been recorded in the Dampier Marine Park. The highest diversity of fish and habitats were associated with recently submerged old-coastline features in the inshore region of the marine park.
