Our History

Next Wave, Next Generation (2025)

While carbon sequestration remains an area of research, we expanded our focus to where seaweed can make the most immediate impact: IMTA, fertilisers, human food, animal feed, and seaweed farm development. With new leadership and a global outlook, our transition from Southern Ocean Carbon to Next Wave Seaweed in early 2025 reflects our broader services, expanded reach and the incredible momentum of the global seaweed industry.

Rooted in Tasmania, Connected to the World

We moved to a new office right by the water at Tasmania's maritime and innovation hub Technopark. We're not far from the Institute for Marine and Antarctic Studies (IMAS), just a couple of hours from the Blue Economy Collaborative Research Centre (BECRC), and surrounded by some of Australia’s largest seaweed product producers. This strategic location places us at the heart of Australia’s thriving seaweed industry, giving us access to world-class research and industry collaboration.
