Anti-bikie and State Crime Command detectives closed two long-running operations on Friday with the arrest of a 23-year-old man from Lawnton, north of Brisbane, and a series of raids.

Police said those busts in Brisbane's north allegedly netted 9.5 kilograms of cannabis, 1.3 kilograms of MDMA and almost 100 grams of cocaine.

Task Force Maxima detective Inspector Phillip Stevens said the seizures would affect the distribution network, which is allegedly linked to the Bandidos, but would be unlikely to have a wider impact.

"They will probably have their staple clientele so it definitely has an impact on their network," he said.

"But in the scheme of things it's probably going to have a limited effect."

On top of the drugs, police said the operations uncovered a cannabis "grow house" at Caboolture, three pill presses used for creating MDMA tablets, two stolen motorbikes and three illegal guns.

The Lawnton man, alleged Bandidos associate Aaron Richard Cowell, was granted bail on 20 drug charges stemming from the discovery of a cache of more than 3000 pills and other drugs from Oceanview, west of Caboolture, in May.

Police estimated those drugs were worth about $200,000, with another $300,000 worth of narcotics seized in subsequent raids.

A Bribie Island man, 26, Lawnton man, 30, and two Caboolture men, 23 and 24, were charged with a range of offences from weapons to drugs charges earlier this month as part of the raids.
