Police have carried out a series of coordinated search warrants across Yarrabilba, Flagstone, Slacks Creek, Regents Park, Kingston and Logan, charging four people as part of a major investigation into an alleged drug trafficking network.
Detectives from Crime Command say the arrests follow an ongoing probe into a transnational organised crime syndicate operating across south-east Queensland.
The investigation, known as Operation Xray Skywalk, began in August 2025 after police received intelligence about drugs being trafficked between Queensland, the Northern Territory, New South Wales, Victoria and Western Australia.
Police allege those at the head of the syndicate were directing activity from overseas using encrypted communication devices.
On Wednesday, 22 April, officers carried out 12 search warrants in suburbs including Yarrabilba, Flagstone, Slacks Creek, Karalee, Regents Park, Logan, Redbank Plains, Calamvale, Upper Mount Gravatt and Kingston.
During the searches, police allegedly seized large quantities of drugs, including 90 kilograms of cocaine, 16 kilograms of methylamphetamine, 311 kilograms of ketamine and 58 kilograms of MDMA.
The drugs have an estimated street value of $20 million.
At warehouses in Yarrabilba and Flagstone, investigators also allegedly found commercial-scale laboratory equipment and precursor chemicals used to produce and extract drugs.
Specialist officers from the Synthetic Drugs Operations Unit attended to safely process and remove the materials.
Four men have now been charged.
A Slacks Creek man, 41, faces four counts of drug trafficking, three counts of producing dangerous drugs and one count of contravening an access requirement.
A Regents Park man, 37, faces the same charges.
A Karalee man, 34, has been charged with four counts of drug trafficking and one count of possessing dangerous drugs.
An Upper Mount Gravatt man, 25, has been charged with two counts of possessing dangerous drugs, along with one count each of possessing items and contravening an access requirement.
He has been granted bail and is due to appear in court on 16 May, while the other three men are expected to appear on 23 April.
Police said 13 people have now been arrested under joint operations Xray Skywalk, Xray Alon and Yankee Revelry, with further charges expected.
