Ghost nets are abandoned fishing nets that make up 30-50% of the world's ocean plastic. They move around via the currents and harm marine life and coral in the process. They take 600 years to break down, and shed microplastics the entire time.

In Australia, most ghost nets end up in the Gulf of Carpentaria, where they impact upon dugong and turtle populations and often wash up on the shores of Arnhem Land. In Numbulwar, artists harvest these ghost nets from the beach to continue their weaving traditions which have been carried out for thousands of years. Each piece of fibre art is completely unique, and draws upon the ancient cultural heritage of the Wubuy and Nunggubuyu speaking clans of the Yolngu nation.
