Heidi has always been an avid lover of nature and the outdoors, so when she was working as a scuba instructor and started finding rubbish everywhere, her only option was to act. In 2004 Heidi co-founded the Tangaroa Blue Foundation as a way of addressing the ever-increasing threat of marine debris in our oceans. Heidi introduced the Australian Marine Debris Initiative, which is a network of communities, schools, industries, government agencies and individuals focused on reducing the amount of marine debris washing into our oceans.
