Join Chloe, Coast and Seas Officer at Green Adelaide and City of Marion staff, for a discovery walk along Hallett Cove beach.

During this walk, you will learn about:

  • The Great Southern Reef (what it is and why it is important)
  • Why we have historically lost seagrass and kelp forests along the metropolitan coast
  • What action you can take (community restoration programs)
  • What species you observe on your beach walk

This event is run in collaboration with Green Adelaide and is supported by the Resilient South Climate Partnership, including the Cities of Holdfast Bay, Marion, Mitcham, and Onkaparinga.
