Hobsons Bay Wetlands Centre supports and collaborates with Jawbone Marine Sanctuary Care Group. JMSCG comprises volunteers who are interested in learning about the marine environment, assisting in maintaining the Jawbone Marine Sanctuary and generally enjoying the marine sanctuary. Members of the group include snorkelers  and SCUBA divers, and people who are just happy to assist the Group and enjoy the Sanctuary from the shore line.

JMSCG will hold its Annual General Meeting (AGM) on Wednesday 5 November 2025 at the Newport Community Hub, which is located at 13 Mason Street, Newport. Following the AGM, they will order pizza and get to know old and new members better. It is a free event, but JMSCG asks that attendees register online so they know how many pizzas to order..
