About the project


In 2019 the Fisheries Research and Development Corporation funded research which aimed to increase the understanding of the social and economic values of man-made marine structures. In Western Australia, we conservatively estimate that there are at least 6000 man-made structures in the marine environment. These include shipwrecks, jetties, marinas, harbours, seawalls, boat ramps, navigation aids and markers, tide stations, artificial reefs, oil and gas platforms, wellheads and oil and gas pipelines.

Man-made marine structures are inhabited by a diverse array of marine life, and are used by recreational and commercial fishers, scuba divers, snorkelers and tourists. As a consequence, these structures have a range of economic and social values reflecting the different user groups.

This webinar provides an overview of identified economic and social values associated with different types of structures and discusses the issues and opportunities associated with people’s values and perceptions. This information will be of use to regulators, proponents and other stakeholders who have an interest in the social and economic values of existing and potential man-made marine structures.
