Cockburn Sound Coastal Alliance

What is the Cockburn Sound Coastal Alliance?

The Cockburn Sound Coastal Alliance (CSCA) is a partnership between the cities of Cockburn, Fremantle, Kwinana and Rockingham and Perth Region NRM. The CSCA receives support from the Departments of Transport, Planning, Environment and Regulation and the Cockburn Sound Management Council and Department of Defence. 

What does the Cockburn Sound Coastal Alliance do?

The CSCA was formed to respond to climate change impacts along the Cockburn Sound coastline, including coastal erosion and inundation. The CSCA recognises that coastal issues are common problems that cross local government boundaries and require integrated and collaborative approaches and solutions, including:

  • Building and sharing knowledge relating to the climate change impacts affecting the Owen Anchorage and Cockburn Sound such as sea level rise, erosion and inundation
  • Developing strategies to help address climate change impacts
  • Developing Coastal Adaptation Plans for its member councils

What area does the Cockburn Sound Coastal Alliance cover?

The project area incorporates the Owen Anchorage and Cockburn Sound (OACS) coast and extends for approximately 45Km from the South Groyne of Fremantle Harbour in the north to the Garden Island Causeway in the south, including the eastern side of Garden Island.

What work has the Cockburn Sound Coastal Alliance completed?

The CSCA has taken a staged approach to climate change adaptation along the Cockburn Coast, which includes:

  • Study brief (completed in 2010)
  • Coastal Vulnerability Study (completed in 2013)
  • Coastal values and Risk Assessment Study (completed in 2014)
  • Coastal Adaptation Plans (completed in 2016)
View the Coastal Adaptation Plans below.

Each local government is now individually responsible for managing the implementation of coastal adaptation measures as it sees fit.
