Ghost gear — the term we use for fishing nets, traps, and lines that have been lost or abandoned at sea — is one of the most stubborn problems in marine conservation. Not because we don’t know it’s a problem. Everyone knows it’s a problem. The challenge is that the gear keeps fishing whether or not anyone’s holding the other end. A monofilament gillnet can drift for decades through the water column, catching fish, sea turtles, sharks, dugongs, and seabirds, until it eventually fragments into smaller pieces that continue causing harm in different ways.

Australia has been working on ghost gear recovery seriously for about fifteen years now, with the bulk of effort concentrated across the Gulf of Carpentaria, the Arafura Sea, the Top End coastline, and select areas of the Great Barrier Reef. I want to take stock of where these programs are at in 2026, because the picture is more nuanced than the success-story framing some media coverage adopts.

Where the Gear Comes From

A common misconception is that all ghost gear is Australian fishing gear that’s been lost locally. Tracking studies done by the Northern Australia Marine Debris Initiative and various university research groups show the picture is much more complex. A substantial portion of the gear washing up on beaches in the Northern Territory and Queensland’s Cape York originates from foreign fishing fleets — Indonesian, Vietnamese, Chinese, and others — operating in or near Australian waters or in the broader Arafura-Coral Sea system.

This matters for management. Australian fisheries are well-regulated, with mandatory gear marking, logbook reporting of lost gear, and a generally strong compliance culture. The bulk of the ghost gear problem we’re trying to solve isn’t an Australian fishing fleet problem in the first instance; it’s a regional problem with international dimensions.

What’s Working: Indigenous Ranger Programs

The single most important development in ghost gear recovery in the last decade has been the expansion of Indigenous ranger programs across northern Australia. Groups like the Dhimurru Aboriginal Corporation in Arnhem Land, Yanyuwa rangers in the Gulf, and various Cape York ranger groups now systematically patrol remote beaches that previously saw almost no debris removal.

The scale of recovery is significant. A single coordinated removal campaign on a remote stretch of NT coastline can pull tonnes of net out of mangroves and dunes in a few weeks. The data these programs collect — origin marking, gear type, location, condition — feeds directly into international fishery management discussions and is some of the best ghost-gear evidence anywhere globally.

The Australian Marine Conservation Society has been a strong partner of these ranger programs, and the data is also informing work through the Indo-Pacific regional fisheries forums.

What’s Working: GhostNets Australia and Successor Programs

GhostNets Australia, originally a project under the World Wildlife Fund, became a model program for collaborative net recovery. After its formal conclusion, successor partnerships and programs continued the methodology. Tagged-net studies have given us actual data on net drift patterns through the Gulf, which has been used to predict where new debris will accumulate after monsoon season — a kind of intelligence-led recovery that’s far more efficient than randomly walking beaches.

The retrieved nets have a second life: many are processed into recycled material in partnership with companies like Net-Works. The economics aren’t large, but the symbolism — and the fact that recovered gear has measurable value — supports community engagement.

What’s Less Working: At-Sea Recovery

Beach-based recovery is relatively cost-effective. Recovering ghost gear from open water is much harder. Sonar detection of nets in the water column is technically possible but expensive. Surface debris is detectable from aircraft and satellite, but most ghost gear is sub-surface or entangled in coral and other structure. Active recovery operations from vessels are limited to specific known sites — wrecks, FAD lines that have failed, reef areas where divers can work — and they’re slow and labour-intensive.

The honest assessment is that at-sea recovery handles a small fraction of what’s lost annually. Most ghost gear that gets recovered, gets recovered after it’s already washed ashore, and after it’s already done a portion of its damage.

What’s Less Working: Prevention Through Marking

Mandatory gear marking — physically labelling every piece of fishing gear so lost equipment can be traced to an owner — is a sensible policy. Australia has it. It works for Australian fleets. It does not work for foreign vessels operating in the broader region without similar regulation. There’s been progress through bodies like the Indian Ocean Tuna Commission and various regional fishery management organisations, but enforcement is the chronic challenge.

I’ve worked with researchers looking at gear marking compliance through visual inspection of recovered nets, and the rate of properly marked foreign gear is depressingly low.

The Wildlife Cost

The animals affected by ghost gear are well-documented. Marine turtles — particularly olive ridleys and flatbacks in the north — feature heavily in entanglement records. Dugongs less commonly, but the cases are usually fatal. Sawfish and various shark species are caught in lost gillnets. Dolphins and dugongs entangled in trap rope. Seabirds caught up in floating debris. The Great Barrier Reef Marine Park Authority keeps incident data on entanglements within the marine park area, and the patterns are consistent.

What 2026 Looks Like

The current funding environment for ranger programs is reasonable. The Indigenous Protected Areas program continues to support ranger groups across northern Australia. State-level funding through the NT and QLD governments adds capacity. Federal contributions through the Marine Debris Initiative and successor frameworks are stable, though never large.

What I’d like to see — and what the field is moving toward, slowly — is more coordinated international engagement. Ghost gear is fundamentally a regional issue. No amount of beach cleanup in northern Australia will fix a problem driven by net loss in the Java Sea. Diplomatic and technical engagement with neighbouring fishery management bodies is where the real influence sits.

For Australians wanting to support the work, donations to the Tangaroa Blue network or to local ranger groups are direct. Beachcombers reporting found gear (don’t move it; photograph and report) help build the long-term dataset.

It’s slow, unglamorous work. The animals it saves don’t generate headlines until something dramatic happens. But every net pulled out of a remote NT bay is a net that won’t kill another turtle next year. That’s the math, and it’s worth doing.
