A 15-kilogram heroin bust in South Australia is believed to be the state's largest single seizure of the illicit drug.
Detectives found the heroin haul along with one kilogram of cocaine on Tuesday at a property at Angle Park, in Adelaide's northwest.
Cash and equipment was seized from a second property, but no arrests have yet been made.
Both properties were residential, and the raid was not bikie-related.
Police said the drugs were found packaged and showed signs of production by a large commercial enterprise.
"Police will continue to tackle organised crime groups, who are involved in the importation, manufacturing and supplying of illicit drugs," Detective Chief Inspector Tina Buckley said.
"We are committed to the reduction of the harm caused by the use of illicit drugs in our community through law enforcement."
Det Chief Insp Buckley said while it was difficult to put an exact value on the drugs, they would have been worth "several million dollars."
"It is a large amount, it's the largest in South Australia that's been seized in recent times," she said.
Police have ruled out any link between the bust and the discovery of the state's biggest clandestine drug laboratories at suburban Morphett Vale last month.
In that raid, officers found 11 kilograms of methamphetamine, or ice, worth $5.5 million.
