Tangaroa Blue Foundation is an Australian-wide not-for-profit organisation dedicated to the removal and prevention of marine debris, one of the major environmental issues worldwide. To assist in solving the problem, we created the Australian Marine Debris Initiative (AMDI), an on-ground network of volunteers, communities, organisations and partners that contribute data from rubbish collected during beach and river clean-up events to the AMDI Database, and then work on solutions to stop the flow of litter at the source. The AMDI helps communities look after their coastal environment by providing resources and support programs, and collaborates with industry and government to create change on a large scale.
