Australia cracks down on $23 billion illegal fishing industry

Australian authorities are taking action against a widespread black market for seafood, issuing substantial fines and destroying boats used in illegal fishing operations.

A man in Queensland was recently fined $10,000 and had his boat destroyed after being caught poaching mud crabs and other seafood. Graeme Bolton, director-general of Queensland’s Department of Primary Industries, explained that mud crabs are valuable and easily sold illegally.

This illegal fishing extends beyond mud crabs to include other species and encompasses activities like fishing in protected areas, exceeding catch limits, and smuggling. Globally, illegal fishing costs legal fisheries up to $23 billion each year and can be connected to crimes like human rights abuses. In Australia, authorities are seeing a rise in prosecutions, with Western Australia prosecuting 273 people in 2025, compared to a much lower number the year before.

To combat the issue, several states are increasing penalties and investing in new surveillance technology. New South Wales recently passed legislation that increases fines for illegal seafood trade to as much as $44,000. Authorities are also concerned about health risks associated with illegally caught seafood, as improper handling and labeling can create dangerous conditions for consumers. They are working to ensure that seafood is traceable and legally sourced.
