Australia might soon become the latest country to ratify the High Seas Treaty. International waters make up two-thirds of the world’s oceans but these areas have been heavily exploited with almost no protection. This treaty could begin to change that. The agreement enables the creation of marine protected areas in international waters. Additionally, thorough environmental assessments would be required for harmful activities like deep sea mining.
Over 80 countries have formally joined. With 55 more having pledged their commitment, making this one of the most significant global agreements on ocean protection in decades. With the High Seas Biodiversity Bill 2026 just having passed through Senate, Australia’s formal ratification process should be concluded in the months to follow.
The Wire’s Shaun Dourado asked Richard Leck, Head of Oceans at WWF-Australia, about what makes the treaty such a landmark moment in our quest to protect the global marine environment.
