FOUR men have been charged with drug trafficking on the Gold Coast, including two members of the Bandidos Outlaw Motorcycle Gang.

The four men were charged with a total of 18 offences on Thursday following a four-month police operation.

The men were arrested after investigators from State Crime Operations Command's Taskforce Hydra searched Gold Coast homes throughout April and seized MDMA tablets, methamphetamine, steroids, cannabis, drug utensils and a sum of cash.

The two men from the Bandidos included a 38-year-old from Surfers Paradise and a 29-year-old Helensvale man, with the others being a 31-year-old from Worongary and a 27-year-old from Upper Coomera.

They will appear in the Southport Magistrates Court on May 6 charged with drug trafficking and other offences.
