Between them, the 19 alleged offenders arrested during the raids, which were also carried out in Bundaberg, Biloela and the Gold Coast, face 51 related charges.
It will be alleged that police and prison guards discovered "high quality" methylamphetamine along with cannabis, morphine and buprenorphine.
