Four high-security Queensland prisons went into lockdown on Sunday night after drones were illegally flown overhead.
Queensland Corrective Services Commissioner Peter Martin said the drone use over Brisbane Correctional Centre, Brisbane Women’s Correctional Centre, Wolston Correctional Centre and Arthur Gorrie Correctional Centre was “irresponsible”.
Queensland Police is investigating the illegal drone use.
The four prisons returned to normal on Monday morning after a search of each property to ensure no contraband had been dropped off.
“The safety and security of our prisoners and staff is of upmost importance, which was put at risk by this ill-conceived stunt,” Commissioner Martin said.
“Drones are a real threat when used to introduce contraband into our prison system or to aid in the escape of prisoners, which is why the Queensland government introduced legislation earlier this year to make such actions illegal.”
A trial at Woodford Correctional Centre was begun this month to detect drones, intercepting communications through radio waves to identify the drone’s source.
The trial will continue for four weeks to test its use across all Queensland prisons.
Drone laws prohibit the use of drones over restricted areas and over areas where emergency operations are under way, and require drones to only be flown at during the day and within line of sight of the operator.
