Australia’s oldest winter swimming club, Bondi Icebergs Club is taking part in this years’ Ocean Lovers Festival for a second consecutive year.

Sea Science @ Bondi Icebergs: The Live Ocean Revival Experience will see Sydney’s iconic Bondi Icebergs’ Pool host an interactive installation by official festival partners, Sydney Institute of Marine Science (SIMS), and presented by Volvo.

Running from Friday 20th – Sunday 22nd March 2020, the installation, which is free to attend and open to all, allows budding oceanographers to dive into the famous Bondi Icebergs’ pool and swim through an underwater Crayweed Forest and Living Seawall display!

Chat with the scientists and learn all the importance of crayweed and restoring the ecology of Sydney’s coastline and harbour. It’s ‘Science in your Swimmers’ for both adults and the kids!

FREE entry for ticket holders from 9am to 3pm, Friday 20th March – Sunday 22nd March. To register, please visit

Vast underwater forests have gone missing from the Sydney coastline, with repercussions for local fish, abalone, crayfish and coastal marine biodiversity!

Seaweeds may not be the most glamorous of sea creatures, but they’re among the most important, providing critical food and habitat that supports hundreds of species. Just like trees on the land, seaweeds form vast underwater forests that underpin coastal food webs, all while quietly capturing atmospheric carbon and producing precious oxygen.

Crayweed provides food and habitat to a huge diversity of fish and invertebrates, including economically important abalone and crayfish. Other species of seaweed do not play the same role in Sydney’s marine environment, so losing crayweed is bad news for our local marine biodiversity!

Crayweed used to also be very abundant along the Sydney coastline, but sometime during the 1980s it disappeared completely from the metropolitan area between Palm Beach and Cronulla. The high volumes of poorly treated sewage that were pumped directly onto Sydney’s beaches and bays before the 1990s likely caused this decline. The problem is that although water quality in Sydney has improved dramatically since the establishment of deep ocean sewage outfalls, the crayweed forests have not returned.

Sea Science @ Bondi Icebergs: The Live Ocean Revival Experience installation by the Sydney Institute of Marine Science will showcase current research projects focused on restoring the ecology of Sydney’s coastline and harbour.

Keen to learn more? The SIMS team with Volvo will give a free talk at Bondi Icebergs Club about the project on Saturday 21st March, 10 – 11am.
