The police and Queensland Corrective Services raided the Palen Creek Correctional Centre to find two portable memory sticks that allegedly contained pornographic images, in the prison officer's locker, the Courier Mail reports.
The officer has been accused of passing on the memory sticks to inmates to upload porn on to their computers.
However, it is yet to be confirmed if the material includes child porn.
The man is charged with bringing in prohibited items to the restricted zone and needs to appear in the Beaudesert Magistrates Court on August 5.
Meanwhile, prison sources at the jail revealed that the officer has resigned after being issued a show cause notice.
Also Queensland Corrective Services have seized a number of computer hard drives belonging to both staff and prisoners for forensic test.
