Australian Police Seize 2.7 Tonnes of Cocaine from Underground Bunkers in Sydney, Largest Bust in Country's History

2.7 Tonnes. Three Underground Bunkers. A$816 Million Street Value.

On June 19, Australian Federal Police executed a search warrant at a semi-rural property in Londonderry, a suburb on Sydney's northwestern edge. Inside three shipping containers near the rear of the site, officers found false floors concealing access to underground bunkers packed with plastic tubs of cocaine. The haul weighed 2.7 metric tonnes, according to the AFP.

That is the largest cocaine seizure in Australian history, surpassing the previous record of 2.34 metric tonnes seized in 2024 from a fishing boat near K'gari (formerly Fraser Island) off Queensland's coast, according to the Associated Press via NPR. It is the biggest Australian drug bust in nearly 20 years, second only to the seizure of 4.5 tonnes of MDMA in Melbourne in 2007, according to The Guardian.

How the Operation Unfolded

Operation Minjiang, run by the Queensland Joint Organised Crime Taskforce in partnership with the AFP, began in May after Queensland Police responded to reports of a burned-out flatbed truck near Midge Point, a small town on the sparsely populated Queensland tropical coast. Officers found 40 kilograms of cocaine floating in the water near a boat ramp there.

Investigators traced the truck's owner, launched searches across north and southeast Queensland, and eventually followed the supply chain 1,800 kilometers (about 1,100 miles) south to the Londonderry property in Sydney, according to Hindustan Times. The cocaine allegedly was landed by boat at Midge Point and transported by road to Sydney on the orders of a Sydney organized crime group.

The Guardian reported that police sources allege the two arrested men were foot soldiers for a syndicate called the Coconut Cartel, which allegedly includes former members of a prominent Sydney crime family.

The alleged mother vessel, MV Wealth, a Belize-flagged cargo ship, has been seized by authorities in Solomon Islands, roughly 2,000 kilometers northeast of Queensland, according to the AP via NPR. Solomon Islands authorities are holding it on suspicion of involvement in transnational organized crime.

Who Was Arrested

Two Sydney men, aged 21 and 25, allegedly tried to flee on foot when police arrived. Both were caught, charged with possessing a commercial quantity of an unlawfully imported border-controlled drug, and remanded in custody after appearing in court on Saturday. Their next scheduled court appearance is on August 13 at Penrith Local Court, according to The Guardian.

The maximum penalty under Australian law is life imprisonment.

Beyond those two, a 32-year-old man and a 32-year-old woman from Petrie, Queensland, have been charged with attempting to possess a commercial quantity of a border-controlled drug. Investigators allege the woman lived at a suspected safehouse linked to the operation, according to Hindustan Times. Six additional people had already been charged in Queensland and New South Wales for their roles in earlier seizures connected to Operation Minjiang, including 178 kilograms of cocaine and 142 kilograms of methamphetamine.

Why Australia, and Why Now

Australia is one of the world's most profitable cocaine markets. Cocaine typically fetches around A$300 per gram there, according to an illegal drugs monitoring system run by the University of New South Wales, cited by BBC. The UN World Drug Report noted last year that Australians and New Zealanders have the highest cocaine use rates in the world.

AFP Commander Stephen Jay put it plainly: "This alleged plot to distribute nearly three tonnes of cocaine demonstrates how highly organised and determined these criminal networks are, and the extreme lengths they are willing to go to in pursuit of profit." Jay also added, pointedly, that the syndicate will be doing "some soul-searching, no doubt, about losing Australia's largest quantity of cocaine."

The Fair Concern Worth Raising

Critics of Australia's drug enforcement approach will argue that record seizures are a lagging indicator of a growing market, not evidence that supply is being controlled. When the previous record haul of 2.34 tonnes was set just two years ago in 2024, and that record has already been shattered, the trajectory points upward. The argument that interdiction alone cannot suppress demand has real empirical weight, and the UN data on Australian cocaine use rates supports it. Those concerns deserve honest engagement.

What the Londonderry bust does establish is that a specific syndicate has now lost an enormous investment, two of its alleged foot soldiers face life imprisonment, its alleged mother vessel is impounded in the Solomon Islands, and additional people across Queensland and New South Wales face serious charges. That represents a measurable operational disruption, even if it does not resolve the broader demand problem.

What Comes Next

Investigations into the origin of the drugs remain ongoing, according to AFP Commander Jay. The MV Wealth's seizure in Solomon Islands is the most concrete international thread still unresolved. Authorities have not yet publicly identified or charged the parties who allegedly loaded the vessel or directed the importation. The question of who organized and financed the shipment before it ever reached Australian waters is the one Operation Minjiang has not yet answered on the record.
