The Management Council comprises 23 members who represent the community; recreation and conservation groups; industry; and Commonwealth, State and local governments.

The Council was established in response to increasing pressures on Cockburn Sound, which is the most intensively used marine embayment in Western Australia.

Just south of Perth, the sheltered waters of Cockburn Sound support diverse marine life and recreational and commercial activities.

Recently, the Council has received additional funding from the government to extend its roles and responsibilities into the area known as Owen Anchorage.

The adjacent map highlights the management area of CSMC, including both the waters of Cockburn Sound and Owen Anchorage as well as their catchments.

An established sub - committee of the CSMC, known as the Owen Anchorage Sub Committee (OASC), will direct the coordination of environmental management for Owen Anchorage. The key focus of the OASC will be to prepare an Environmental Management Plan for Owen Anchorage and its catchment.
