It is a privilege to be welcomed back onto Yolŋu Country, where we come as guests with deep respect and humility. Our shared mission is to protect the coast of the Dhimurru Indigenous Protected Area, combining traditional knowledge with modern conservation practice. The Dhimurru Rangers are expert land managers and cultural custodians who know this Country intimately — its nesting turtle sites, seasonal rhythms, sacred places, and where the need for clean-up is most urgent. Sea Shepherd crew bring the grit and determination needed to spend a week hauling ghost nets and picking up plastic, adding extra hands to a crisis the Rangers face year-round — but it is always the Rangers' leadership that guides our actions. 

Despite its isolation, Waṉuwuy is besieged by the global plastic crisis. A never-ending tide of foreign waste — fishing nets tangled with shampoo bottles, cigarette lighters, and toothbrushes — arrives on currents that have carried it thousands of kilometres, smothering a coastline far from where the plastic originated. Dhimurru Rangers have safeguarded this coast for over 30 years and have long warned that marine debris is damaging these sacred coastlines. Plastic was never part of the songlines that tell the story of these beaches, and the damage it is doing to the marine life here is devastating. 

On these beaches, we have found wildlife caught up in pollution — turtles entangled in nets, seabirds with stomachs full of plastic. Ghost nets pose a huge threat: lost or discarded fishing gear, drifting at sea for months or years, becomes a trap for anything unfortunate enough to cross its path. Eventually these nets wash up on shallow reefs or onto the shore, where they remain a danger to nesting turtles and shorebirds in the region. Every net and rope we remove is one less to threaten marine life. At the end of each day, the crew would often stand silently on the beach, reflecting on that reality. 

The clean-up in numbers

These figures tell only part of the story. How we achieved them comes down to the teamwork of the crew and the Rangers, and what each day demanded of them. Because of the remote location, we camp on-site — no power, no facilities, no luxuries. Days start at 6am, before the heat sets in, with the crew already moving out into the pre-dawn light. At Nanjḏuka, the first beach location, 2,169 kg of debris was hauled off just a few hundred metres of coastline — bag after bag filling as the sun climbed higher — before loading the 4WDs and driving over rough terrain to the next site. 

Removing every piece of rubbish by hand is physically demanding, and a painstaking reminder of the consequences of a throw-away culture. Much of this pollution comes from products used for only a few minutes — many of which have easy plastic-free alternatives. 

At the end of each day, the crew sorted a sample of the day's haul, tallying what had come off the beach — data that helps us understand the extent of what's washing up, where it comes from, and what kinds of products are involved. Then, finally, everyone sat down together to eat under a truly spectacular, star-filled sky, untouched by light pollution, with the nearest town two hours' drive away. 

The endless cycle of marine debris washing ashore disrupts a relationship with Country built over generations. The Yolŋu people know this land, and know when it provides for their seasonal harvest. Now, that calendar carries a second rhythm alongside it — not just when to harvest, but when the debris will wash up again. 

It has now been shown that plastic leaches harmful chemicals as it breaks down in the sun and the ocean — chemicals that enter the food chain, directly impacting our own health as well as marine life. 

Moving Forward with Hope and Renewed Determination

The best feeling at the end of these remote clean-up campaigns comes once camp is packed up, the gear is loaded, and the crew drives back over beaches that, only a week earlier, were drowning in plastic waste. The feeling is a mix of pride and resolve. We know this is a cycle — the ocean will bring more plastic, and our work will continue — but rather than discouraging us, it fuels our determination. Each campaign doesn't just reduce the plastic on these beaches; our documentation raises awareness of the scale of the crisis and the need to address it at its source, and strengthens our commitment to solutions that are Indigenous-led and respectful of Country. As we set up camp for our next clean-up, we carry these lessons forward.
