An alleged Finks gang member and a Mongols associate have been charged by Queensland's anti-bike squad, following a half-million dollar drug haul south of Gympie.

Taskforce Maxima detectives and members of the State Crime Command discovered two drug crops at rural properties in remote Amamoor, south of Gympie, on November 30.

The sophisticated production set-up police will allege they found during the raids included drying sheds, a hydroponic nursery and a range of growing equipment and crop materials.

On Tuesday, detectives charged a 49-year-old Gympie man on three drug-related offences, including drug production and possession, as well as possession of associated production paraphernalia.

The man, allegedly a member of the Finks outlaw motorcycle gang, was bailed to appear at Gympie Magistrates Court on December 15.

Police will also allege the raids led them to search a 22-year-old Gold Coast man with Mongols gang links on Tuesday.

The man, currently in custody at Wacol Correctional Centre, was allegedly found in possession of a mobile phone, a synthetic opiate and a shortened needle and syringe.  

He has been charged with possession of a prohibited article and is scheduled to appear at Richlands Magistrates Court on January 6.

Taksforce Maxima was established in late 2013, as part of the Newman Government's bid to crack down on the activities of criminal motorcycle gangs in Queensland.

Acting Detective Inspector David Cove said bikie gangs were a major player in the supply of dangerous drugs.

"Criminal Motorcycle Gangs are responsible for the misery that comes with this trade," he said.

"Taskforce Maxima is committed to uncovering and eliminating the illicit activity of Criminal Motorcycle Gangs.

"Sustaining strong partnerships is a cornerstone to achieving our commitment.

"The arrest at a correctional centre is an example of the close working relationship established with State Crime Command and Queensland Corrective Services and the successful outcomes these partnerships are yielding."
