Six people have been charged following a major police investigation into an alleged methamphetamine supply network operating across suburbs in Sydney's south.

Detectives from St George Police Area Command began the investigation in March 2026, focusing on suspected drug supply activity across several suburbs, including Peakhurst, Penshurst, Rockdale, Hurstville, Riverwood, Arncliffe and Narwee.

Police allege the network operated as a “dial-a-dealer” service, supplying methamphetamine directly to customers. Investigators say the operation involved a large number of transactions and continued over an extended period.

As part of the investigation, police carried out a series of search warrants at properties across the region. During the searches, officers allegedly seized methamphetamine, cocaine, cannabis, cash and electronic devices.

Police estimate that more than six kilograms of methamphetamine, with an estimated street value exceeding $700,000, was distributed through more than 2,000 alleged transactions.

Six people have now been charged in connection with the investigation. The accused include people from different age groups, with police alleging they played various roles in the distribution network.

The arrests represent a significant development in the investigation, but police say inquiries are continuing. Investigators are examining the evidence seized during the raids and are working to establish the full structure of the alleged operation.

Drug-supply investigations can involve extensive analysis of phones, electronic devices, financial records and communications. Police may use this information to identify relationships between alleged suppliers, distributors and customers.

The operation demonstrates the ongoing efforts of NSW Police to target organised and street-level drug supply in Sydney communities. Methamphetamine remains a major concern for law-enforcement agencies because of its potential impact on individuals, families and communities.

The investigation has involved multiple Sydney suburbs, making it a significant south-Sydney policing operation rather than an isolated incident at one location.

Police have not indicated that every person connected to the alleged network has been identified, and further investigative activity may follow.

All people charged are presumed innocent unless proven guilty in court. The charges represent allegations made by police and will be considered through the judicial process.
