The investigation, spanning 14 months, found more than 25 alleged drug couriers connected to a 35 year-old Brisbane man.

Queensland Police will allege more than $50 million in drugs, including methylamphetamine, ketamine and cocaine, were sold by the group during a 14-month period.

This police operation caused a major disruption to south-east Queensland's drug supply, detective senior sergeant Ken Rogers said in a statement.

Police have released dramatic footage of the raids, showing wads of cash and bags of drugs pulled from hiding spots in cars and homes.

Footage shows police searching a vehicle, allegedly used by the group, and finding a concealed area packed with $330,000 cash, drugs, a mobile phone and a money counting machine on January 19.

Police searched bushland in Brisbane's north-west on February 1, finding a drug lab in a demountable building.

The charges against some of the group members include drug trafficking, modifying construction of firearms, unlawful possession of weapons and other drug-related offences.

"I encourage anyone with information in relation to illicit drugs in our community to contact police or Crime Stoppers," detective senior sergeant Ken Rogers said.

"Together we can, and do, make a difference," he said.
