The Nets That Keep Fishing After the Boats Go Home

A fishing boat can leave the horizon while part of its gear keeps working. Lost, abandoned or discarded nets drift through the sea, wash into mangroves and continue catching animals without anybody tending them. The boat goes home. The net stays on shift.

In northern Australia, the bill for that long, ugly shift often lands on remote beaches and the people caring for them. The Gulf of Carpentaria is recognised by Parks Australia as a global hotspot for ghost nets. Some nets travel hundreds of kilometres, weigh tonnes and arrive with enough rope and plastic to turn a beautiful shoreline into a very bad day at the office.

The damage does not stop at the tide line

Ghost gear can entangle turtles, dolphins and other marine life, damage habitats and create hazards for boats. Australian Fisheries Management Authority guidance says most ghost nets found in Australian waters appear along the northern coastline from Broome to the Torres Strait. Many of the net types are not used by Australian Commonwealth fishers, which means currents can carry a distant failure into somebody else’s Sea Country.

That is an environmental problem, but it is also a question of fairness. Communities with the least control over where the gear was lost are left to find it, assess it and drag it from places that may be difficult to reach by road, boat or even on foot. A net on a city beach might bring machinery by lunchtime. A net on a remote Gulf beach may require a drone survey, a winch, a vessel and people who know exactly where the tide will put it next.

Rangers are doing the patient work

Between 2021 and 2025, a federal coastal clean-up project worked with 24 Indigenous ranger groups across northern Australia. The Department of Agriculture says the teams covered 1,725 kilometres of coastline, removed 900 ghost nets and collected 190,000 kilograms of marine debris. More than three quarters of that debris was plastic.

The numbers are impressive, but they can flatten the skill inside the work. Rangers combine knowledge of Country and seasons with boats, drones, mapping and image-recognition tools. Technology helps locate debris hidden along a vast coastline. It does not lift a waterlogged net, read a dangerous shoreline or replace the judgement of the crew standing there.

ABC reporting from 17 June 2025 followed the Numbulwar Numburindi Rangers, whose small team cares for roughly 300 kilometres of remote coast. It also described work by the Anindilyakwa Land and Sea Rangers with Charles Darwin University: a drone survey across 84 kilometres identified 72 ghost nets, some buried so deeply that heavy equipment was needed. There is nothing glamorous about hauling someone else’s plastic out of sand. There is a great deal of value in it.

Removal matters. Prevention matters more.

Australia announced a new $25 million, four-year program in January 2026. Parks Australia says $20.6 million will expand ranger-led work in northern Australia, including removal, recycling and better detection. A further $4.5 million is intended for cooperation with Indonesia, Papua New Guinea and Timor-Leste so fewer nets enter shared waters in the first place.

That second part deserves attention. A clean-up is necessary, but it is not a victory lap. If the same gear keeps arriving, the coast has merely been enrolled in an endless rubbish roster. Tracing likely origins, improving fishing-gear management and working across borders are what turn removal into prevention.

One useful act

If you see a ghost net in or near an Australian Marine Park, do not try to haul it out yourself. From a safe position, note the location, describe what you can see and take photographs only if it is safe. Parks Australia asks the public to report sightings to Marine.Compliance@dcceew.gov.au or its 24-hour line on 1800 852 975. A useful report can help a trained team plan a retrieval without adding another person to the danger.

Then give the ranger-led work its proper name: skilled land-and-sea management, not background scenery for an environmental campaign. The people cleaning these shores are not waiting to be discovered. They are already out there, reading the coast and doing the job.
