The cocaine, estimated to have a street value of A$816 million ($572 million), was discovered on June 19 at a semi-rural property in the western Sydney suburb of Londonderry, the Queensland Joint Organised Crime Taskforce said on Monday.

Investigators said the drugs were hidden in plastic tubs buried in underground bunkers accessible through false floors installed inside three shipping containers on the property.

Two Sydney men, aged 21 and 25, were arrested at the scene and charged with possessing a commercial quantity of an illicit drug. If convicted, they face potential life sentences under Australian law.

The seizure surpasses Australia’s previous record cocaine interception of 2.34 metric tons, recovered from a fishing vessel near K’gari, formerly known as Fraser Island, off the Queensland coast in 2024.

Authorities allege the shipment entered Australia through Midge Point in Queensland before being transported approximately 1,800 kilometers by road to Sydney by an organized crime network.

Police believe the drugs originated from the same mother ship linked to an earlier seizure of 178 kilograms of cocaine and 142 kilograms of methamphetamine in Queensland. Six individuals have already been charged in connection with that investigation.

Investigators suspect the vessel involved is the Belize-flagged cargo ship MV Wealth, which has been detained by authorities in the Solomon Islands over suspected links to transnational organized crime activities.

The Solomon Islands lie roughly 2,000 kilometers northeast of Queensland and have increasingly attracted law enforcement attention as authorities monitor trafficking routes across the Pacific region.

Australian Federal Police Commander Stephen Jay said criminal syndicates were increasingly exploiting Queensland’s extensive 13,000-kilometer coastline to import illicit drugs into Australia.

The seizure highlights the continued attraction of the Australian narcotics market to international trafficking organizations. Law enforcement agencies note that Australians pay some of the highest prices globally for cocaine, making the country a highly profitable destination for organized crime groups despite intensified border enforcement and interdiction efforts.

Investigations into the trafficking network and the origins of the shipment remain ongoing.

Wale, elected by lawmakers on Friday after the removal of former prime minister Jeremiah Manele, named former premier Rick Hou as foreign minister and legislator Peter Kenilorea as minister for National Planning and Development Coordination, portfolios central to the country’s foreign aid and diplomatic engagement.

The appointments are being closely watched by regional governments and Western allies as the strategically located Pacific archipelago remains an arena of competition between China and Australia for political and security influence.

Kenilorea is a member of the Inter-Parliamentary Alliance on China, a multinational group critical of Beijing’s policies. James Batley, a former Australian high commissioner to the Solomon Islands, said the appointments suggested a greater emphasis on transparency, although he said it was unlikely Honiara would reverse its 2019 decision to switch diplomatic recognition from Taiwan to China.

Hou, who served as prime minister from 2017 to 2019 before the diplomatic switch, had publicly opposed the move to sever ties with Taiwan. Batley described Hou as experienced in international affairs and unlikely to be easily pressured in diplomatic negotiations.

Chinese Ambassador Cai Weiming and Australian High Commissioner Jeff Roach both met Wale over the weekend as regional powers moved quickly to engage the new administration.

According to a statement from the prime minister’s office, Wale told Cai that the Solomon Islands remained committed to the One China policy and intended to continue cooperation with Beijing to deliver economic benefits.

In separate talks with Australia, Wale said Canberra should adopt a longer-term approach to deepening bilateral ties, while describing Australia as the country’s longstanding development partner.

The government also restored a prohibition on the export of live dolphins, reversing a decision by the previous administration to lift the ban days before its collapse.

Environmental campaigner Lawrence Makili welcomed the move, saying it would help protect both marine life and the international reputation of the Solomon Islands’ tuna industry, one of the country’s largest sources of export revenue.

The issue gained prominence after a company applied to capture and export 50 dolphins, prompting criticism from conservation groups concerned about the impact on marine ecosystems and trade perceptions abroad.

While dolphin hunting in Malaita has historically been tied to traditional practices involving dolphin teeth, the commercial export of dolphins to aquariums in China has drawn increasing scrutiny in recent years.
