Charles Darwin University (CDU) and the Anindilyakwa Land and Sea Rangers are employing advanced drone technology to combat the persistent problem of ghost nets along the Northern Territory's coastline. These abandoned fishing nets pose a significant danger to marine ecosystems, trapping vulnerable species such as endangered turtles and dugongs. The initiative has involved drones equipped with hyperspectral sensors surveying 83.74 kilometers of remote coastline within the Anindilyakwa Indigenous Protected Area. This aerial method is more efficient and cost-effective than traditional helicopter surveys, which are often hampered by difficult weather conditions and high expenses. The hyperspectral technology enables detailed identification of debris, even in remote and inaccessible areas.
As of June 2025, this targeted drone surveillance has identified 72 ghost nets, ranging in size from small fragments to substantial nets exceeding five meters in length. The precise location data provided by the drones is crucial for the Rangers to plan and execute effective, localized removal operations. Ghost nets continue to indiscriminately "fish," causing significant harm to marine life and contributing to the breakdown of marine ecosystems into microplastics. The project also focuses on building capacity within the Anindilyakwa community, with ten Anindilyakwa Rangers having obtained a Certificate III in Aviation (Remote Pilot), equipping them with the skills to operate drones safely and in compliance with aviation regulations. This local empowerment ensures that the benefits of this conservation effort remain within the community, promoting long-term stewardship. This collaborative project demonstrates how cutting-edge aviation technology can significantly enhance environmental conservation, particularly in Australia's vast and remote regions. The involvement of the Anindilyakwa Land and Sea Rangers highlights a model for community-led, technology-assisted marine debris management, offering a scalable solution for similar global challenges. The initiative is supported by the Australian Government through Parks Australia's Ghost Nets Innovative Solutions Grant.
