Five people have been charged with attempting to smuggle more than $1 million in illicit drugs into a Queensland prison over the past two months.
More than 1100 subutex strips - which contain the drug Buprenorphine and are used to treat opioid addiction - were seized at Woodford Correctional Centre on January 24.
Methylamphetamine, other drugs and cash were also seized in the prison crackdown.
Two women, aged 46 and 32, and a 27-year-old man have been charged with drug, dishonesty and property offences and remain before the courts.
A female visitor was intercepted on February 15 attempting to smuggle more than 370 subutex strips at the same prison.
She has been charged with supplying dangerous drugs and circumstances of aggravation in a correctional facility.
A 36-year-old male prisoner was also charged in relation to the incident.
The pair will face court in April.
Queensland Corrective Services Deputy Commissioner Gary McCahon said those arrests should serve as a warning against attempting to smuggle drugs into prisons.
"Anyone who attempts to bring contraband into correctional centres will be caught," he said.
