Australian Federal Police seized approximately 2.7 tonnes [1] of cocaine from a semi-rural property in Londonderry, Greater Western Sydney, this week.

The operation marks the largest cocaine seizure in Australian history, disrupting a massive supply chain and removing a significant volume of narcotics from the streets.

Officers discovered the haul on Friday, June 20, 2026 [2]. The drugs were hidden within plastic tubs, and underground bunkers located on the property [3]. The seizure occurred as part of an ongoing drug-trafficking investigation [3].

The estimated street value of the shipment is reported between $800 million [1] and $816 million [4].

Authorities arrested two men in connection with the discovery. One suspect is a 21-year-old man from Plumpton, and the second is a 25-year-old man from Liverpool [1].

Police officials said the record-breaking operation occurred Monday, June 22, 2026 [2]. The investigation into the origin and intended distribution of the cocaine continues as authorities work to dismantle the associated trafficking network.

The largest cocaine seizure in Australian history

The scale of this seizure indicates a sophisticated logistics operation capable of moving multi-tonne shipments into New South Wales. The use of underground bunkers suggests a high level of investment in secure infrastructure, signaling that organized crime groups are utilizing rural properties in Greater Western Sydney as strategic hubs for large-scale distribution.
