Sea The Weed: Ceremony, Science, Snorkel

Hands-on experience opportunity alert! As part of our Ian Potter Foundation project, AIME’s Ocean Ambassadors will lead monthly ‘Sea the Weed: Ceremony, Science and Snorkelling’ events, on the last Friday of every month in 2025. These immersive experiences start with a ceremony grounded in traditional ways, including an in-depth explanation of the science behind kelp restoration and conclude with a guided snorkelling session at a restoration site. 

See below some photos from an event from last year, which was attended by the Operation Crayweed team who provided an update on the project.

Please keep updated on the AIME social channels and the schedule below about where the next event will take place!

Restoration efforts supercharged by The Ian Potter Foundation

We are thrilled to announce that our initiative, Local to Global Strategies for Accelerating Kelp Restoration, has received funding from The Ian Potter Foundation, an Australian philanthropic organisation that provides grants to support initiatives in the arts, environment, education, health, and community wellbeing. This generous support will enable us to implement our plans over the next four years, with a focus on restoring crayweed forests at more critical sites along the Sydney coastline.

In collaboration with the Kelp Forest Alliance, this initiative aims to reconnect crayweed habitats, enhance the rich biodiversity they sustain, and contribute to the global mission of protecting and restoring 4 million hectares of kelp forests by 2040. These efforts will not only help safeguard marine ecosystems but also highlight Australia's role as a leader in marine restoration.

We are also proud to partner with AIME to share our collective story with the broader community. Through this partnership, we aim to foster a deeper connection to our underwater world, inspiring people to value and protect these vital ecosystems.

We are eager to embark on this important work and look forward to sharing our progress with you in the months and years ahead. Thank you for your ongoing support in helping us make a difference for our oceans!

Investa & Operation Crayweed: A successful partnership for restoration

Thanks to the partnership with Investa, Operation Crayweed has recently expanded restoration efforts to three new sites along the Sydney coastline, with inspiring results. Lurline Bay, Dee Why and South Maroubra were planted during the winter of 2024, by the Operation Crayweed team with the help of Investa volunteers.

In December 2024, surveys at the new restoration site in Dee Why revealed 466 crayweed recruits (‘craybies’). At Lurline Bay, first planted in late 2023 and ‘topped up’ in winter 2024, 416 recruits were recorded, up from just 10 last year. The tallest recruit there has already grown to 47 cm! The third site, South Maroubra, will be monitored in January 2025 – so stay tuned on our Instagram @thetrueoperationcrayweed for more news.

Making waves: athletes helping restore Sydney's marine ecosystem

On August 14, we at Operation Crayweed had the privilege of hosting a remarkable event, “The Ultimate Recovery Session,” at South Coogee Beach. Together with Gemba and some of Sydney’s most beloved athletes, we took another significant step toward restoring Sydney’s lost crayweed forests.

Thanks to Gemba’s generous support through their ‘Dividend for the Planet’ initiative, this event was not only possible but also impactful. Gemba allocated 2% of their annual profits to our cause and provided pro-bono services to help us organise this special day.

Athletes from teams like the GWS GIANTS, Sydney FC, and the Sydney Swifts braved the winter waters to assist in planting juvenile crayweed. Winter is the perfect time for crayweed growth, and these efforts are crucial for revitalising marine ecosystems.

We’re incredibly grateful to the athletes, volunteers, and supporters who joined us. As Professor Adriana Vergés highlighted, restoring crayweed brings back entire marine communities, ensuring healthier oceans for future generations.

This event was a testament to what we can achieve together. Thank you for helping us rebuild Sydney’s underwater forests, one crayweed at a time!

Compostable Hoodies to Fund Restoration

In an innovative collaboration, the Regenerators and AIME have introduced one of the world's first custom-designed, fully compostable hoodies made from seaweed. This initiative aims to raise $1 million to support the efforts of Operation Crayweed, by selling 2000 of these hoodies!

By purchasing one of these seaweed hoodies, you directly contribute to the reforestation of Sydney's underwater ecosystems. Each sale brings the project closer to its $1 million target, which will contribute to facilitating the re-establishment of crayweed in Sydney. This initiative not only offers a sustainable fashion choice, but also provides an opportunity to play a part in restoring Sydney's marine ecosystems. Huge thanks to AIME and the Regenerators for their unique and ambitious partnership, and to Damon Gameau for the fantastic video below!

Science Meets Art at Balgowlah North Public School

A group of talented Year 4 students from Balgowlah North Public School have teamed up with artists Jennifer Turpin and Michaelie Crawford, curator Christiane Statham (Turpin + Crawford Studio), filmmakers from Lightwell Studio, and musician Ben Fink to create a unique animated film about Operation Crayweed.

The journey began with hands-on excursions to the Long Reef rock platform and the Sydney Institute of Marine Science (SIMS)’s Marine Lab in Chowder Bay, where the students discovered the science behind crayweed restoration. Inspired by their learning, they brought the project to life through drawing, songwriting, singing, and dancing, transforming marine science into a creative and engaging film.

This short film is the latest in an ongoing series of art and science collaborations between Turpin + Crawford Studio and Operation Crayweed. By blending creativity with environmental education, the project aimed at empowering young people to become ambassadors for ocean health, and at raising awareness about the vital role of restoring crayweed for the wellbeing of Sydney’s underwater ecosystems.

This project was supported by the John T Reid Foundation.

We are bringing crayweed back to Cabbage Tree Bay, in Manly!

Since starting our underwater gardening in 2011, Operation Crayweed has had the privilege of working at many beautiful coastal locations around Sydney. Now, Operation Crayweed has been given access to a very special and stunning location: the Cabbage Tree Bay Aquatic Reserve, in Manly. Designated as a sanctuary zone in 2002 where no fishing is allowed, Cabbage Tree Bay is the first aquatic reserve we have worked in.

Volunteers from Friends of Cabbage Tree Bay assist with the sorting and measuring of crayweed before it is transplanted.

Cabbage Tree Bay is a spectacular place in many regards. The traditional custodians of Cabbage Tree Bay, the Kameraigal clan, revered the bay for plentiful fishing and perfectly protected camping. Since the instalment of deep ocean outfalls and since becoming protected from fishing, Cabbage Tree bay has become one of the most diverse marine communities in Sydney, with over 50 invertebrate species and 160 fish species having been identified.

Nowadays Cabbage Tree bay has become famous for its dusky whalers congregations over Easter, the giant cuttlefish mating displays through the winter, and the vibrant and diverse fish communities all through the year.

Now, for the first time in roughly forty years, crayweed is one of the species found at
Cabbage Tree Bay.

It is through members of the local community that Operation Crayweed has been given the opportunity to bring crayweed back to the bay. Dorset Sutton and Jenny Lim (The Sutton-Lim Initiative) have partnered with Operation Crayweed and The Sydney Institute of Marine Science, with the shared goal of further enhancing the already vibrant underwater-scape of Cabbage Tree Bay.  

With their help we have been able to ‘plant’ crayweed at three different locations around the bay, and now eagerly await the appearance of ‘craybies’.

The people that watch over Cabbage Tree Bay are a big part of what makes it such a special place, including the Friends of Cabbage Tree Bay community and the Bold & Beautiful swimming groups, who are present every day, protecting it and educating visitors. 

The exciting task of preparing and planting crayweed was documented by the team at Grumpy Turtle Design. We are thrilled to have so many Cabbage Tree Bay locals, and marine enthusiasts join us in the project.

Operation Crayweed would also like to thank John T Reid Charitable Trusts for their ongoing contribution to this project.

The Future of the Pacific and its Societies

In June 2017, UNSW Sydney hosted the 21st Presidents Meeting & CEO Summit "The Future of the Pacific and its Societies".

This meeting brought together leaders from the Association of Pacific Rim Universities (APRU) network to discuss issues affecting our region and to develop strategies that can have a meaningful impact on our region's future.

To mark the occasion, the Operation Crayweed team planted a new underwater crayweed forest in iconic Bondi Beach on behalf of all APRU delegates.
