The ocean is the pumping heart of our planet. It provides us with oxygen, regulates our global climate through highways of moving currents, and provides food for people and marine wildlife alike. But our ocean is under threat from human impacts such as litter and other pollutants, which kill and injure wildlife, and pose a threat to human health.

CVA is committed to playing our part in improving the health of our ocean, wetlands and rivers.

Help us #SeaTheChange!

Committed to empowering action

In the last 3 years alone we have mobilised 11,000 volunteers to locate and remove over 19,000 kgs of litter. That’s more than 380,000 pieces of litter with 299,300 of those life-threatening plastics taken from beaches and rivers around Australia.

Over the next 5 years, we are committing to activating a community of people to remove 30 tonnes of rubbish from entering the environment as we continue to work with CSIRO to expand their National Plastic Pollution Baseline Survey across the country.

"About 80 per cent of the marine turtles that come to the Taronga Wildlife Hospital are affected by plastic waste."

For ocean health

Since 2020, powered by the volunteer efforts of tens of thousands of Australians, our partnership with CSIRO has provided insights into the sources of waste entering our waterways. 50 of the country’s largest businesses have also joined us to locate and remove marine litter from beaches, preventing it reaching or re-entering the ocean. In 2024, under the banner of “Sea the Change”, we are working with key partners and communities to not only remove harmful plastic pollution, but to highlight and influence the behaviours and systems that allow it to become a problem in the first place.

For wetlands and rivers

It is estimated that 80% of the plastics in our ocean enter through our river systems with rivers and wetlands equally impacted by litter and other pollutants. Together, we can help restore and protect important wetlands across Australia so they can retain their function as natural water filters and havens for aquatic life in their own right. We also target urban rivers and creeks, removing gross pollutants to prevent them from ever reaching the sea.

For stopping litter at the source

Much of the plastic pollution that impacts ocean, wetlands and rivers finds its way there from urban areas. Streets, parks, industrial zones, and shopping strips – our work with CSIRO tells us that these are all significant sources of ocean pollution. Available via our CVA app, the #SeaToSource Plastic Waste Challenge is a fun and engaging way to help identify and reduce anyone’s plastic footprint. SeaToSource is a national citizen science project that helps tackle marine pollution at the source.
