Australia Cracks Down on $23 Billion Illegal Fishing Industry

Australia's seafood industry is under threat from widespread illegal fishing, with authorities cracking down on the black market trade in a bid to protect marine ecosystems and the livelihoods of legitimate fishermen.

Illegal fishing, which includes poaching in protected areas, ignoring catch quotas, and smuggling, is estimated to cost the global industry up to $23 billion annually. In Australia, the domestic illicit seafood trade involves both recreational and commercial anglers selling stolen seafood on the black market, often directly to restaurants, markets, and street vendors.

The Crackdown on Illegal Fishing

In Queensland, authorities have been targeting those involved in the illicit trade, with 1,809 reports of illegal fishing investigated between 2024 and 2025, and 14 matters prosecuted in the Magistrates Court. One 43-year-old man was caught poaching mud crabs and selling them on the black market, earning up to $64 per kilo for high-quality crabs.

"Mud crabs can retail anywhere up to $64 a kilo for high-quality, top-grade mud crabs," said Graeme Bolton, director-general of Queensland's Department of Primary Industries. "So they're high value, they're easy to transport, and readily sold on the black market."

In one case, a 46-year-old Gold Coast man was caught hiding crabs in his boat, and his vessel was subsequently crushed. Another man was convicted and fined $10,000, and his boat was destroyed.

"This is really to send a very clear message that unlawful activity in Queensland will not go unpunished," Mr Bolton said. "People try to hide fish and crabs underneath floorboards or ... within the boat or cars, [sometimes even] dropping fish and crabs in the bush somewhere."

The Impact on Legitimate Fishermen

The black market trade not only threatens marine ecosystems but also erodes the ability for legitimate fishermen to make a living. According to Peter Jenkins, a wholesaler from Victoria, he has lost count of the number of times he has been offered illegal seafood.

"The population's getting greater and the fishermen are getting less, and of course everything's worth fairly big money now," Mr Jenkins said.

Roy Palmer, a safe seafood consumer advocate, says incorrect labelling of seafood could mean the fish has been illegally caught and may pose serious health risks.

"That's why we license fishermen," Mr Palmer said. "We license fishermen because they have to understand how the system works and that they must follow protocols to get the product through to the consumer."

New Legislation and Enforcement

In New South Wales, new legislation has been introduced, including increased fines of up to $44,000 for those caught engaging in the illicit seafood trade. Authorities are also investing in new technology to track offenders.

"We want people to know that they can't get away with this behaviour in NSW," state Minister for Agriculture Tara Moriarty said.

The crackdown on illegal fishing is a significant step towards protecting Australia's seafood industry and marine ecosystems.
