The 2025-26 harmful algal bloom reset our coastal ecosystems, but divers are observing incredible resilience and beauty on our reefs. We have strong evidence now of the return of tunicates, sponges and octocorals on jetties and wrecks, and the reemergence of nudibranches, goblin fish and other wonderful marine creatures. There is much to celebrate in SA waters!
The role of the Scuba Divers Federation of SA
Our Federation brings together SA’s recreational scuba diving shops, clubs, related NGOs and individual divers, snorkellers and free divers. We work with the State, local councils and others to ensure the enjoyment and preservation of our unique underwater world. Our priorities include opening or improving dive sites, jetty maintenance, navigation trails, marine life protection, and dive community support through events and information sharing.
