Operation DJANGO fighting illegal exotic animal trade

23 October 2026

Agriculture Victoria is continuing its crackdown on the illegal network trading in exotic pest animals, with another investigation resulting in convictions and significant fines.

A Melbourne aquarium business and its director have been convicted and fined a combined $25,000 for offences involving noxious aquatic species and the illegal trade of protected native wildlife. M&R Aquarium Pty Ltd and its director Raymond Mai were convicted at the Sunshine Magistrates’ Court last month, with the company fined $11,000 and Mr Mai fined $14,000.This outcome is the latest from Operation DJANGO, a joint initiative between Agriculture Victoria and the Conservation Regulator, supported by Crime Stoppers Victoria.

In July 2025, Authorised Officers executed search warrants at Maribrynong, Derrimut and Burnside properties connected to the aquarium business, seizing 108 koi carp.

The investigation found more than 600 koi carp had been illegally brought into Victoria from interstate, with other noxious aquatic species also offered for sale.

Koi carp are declared a noxious aquatic species in Victoria and can pose a significant threat to waterways and native fish populations if released into the environment.

The investigation also uncovered offences involving the illegal possession and trade of protected native wildlife without the required wildlife licence.

The investigation involved collaboration between Agriculture Victoria, the Conservation Regulator and the Victorian Fisheries Authority, working together to address illegal animal trade and protect Victoria’s environment and biosecurity.

Operation DJANGO Project Manager Adam Kay said convictions like these help protect Victoria’s biosecurity system and provide an important deterrent to others involved in the illegal animal trade.

‘Operation DJANGO is about disrupting the illegal trade of animals and reducing the risks these activities pose to Victoria’s environment and biosecurity,’ Mr Kay said.

‘This result sends a clear message that people and businesses involved in illegally importing, keeping or selling noxious aquatic species can expect to face enforcement action.’

‘We remain committed to working across government to disrupt the interconnected illegal animal trade, and take appropriate enforcement action against those responsible.’

Conservation Regulator Manager of Wildlife Crime and Intelligence Steph Andreata said efforts to target illegal wildlife trade and hold offenders to account will continue.

‘The illegal trade of native wildlife puts animals at risk and undermines Victoria’s wildlife licensing system. Those who operate outside the law can expect enforcement action.’

Anyone with information about the illegal trade of native wildlife or exotic pests, is encouraged to contact Crime Stoppers Victoria on 1800 333 000 or online. Reports can be anonymous.
