There are serious concerns about the safety of prisoners in Queensland jails after a prison worker was charged with multiple counts of rape.
The male prison worker has been charged with three counts of rape, sexual assault and abuse of office while working at the Brisbane Women's Correctional Centre and was granted bail on Wednesday.
Prisoner advocates, lawyers and doctors say the case is further evidence that rape is common in Queensland prisons.
Debbie Kilroy from the prisoner support group Sisters Inside says it is one of the rare cases that has made it to court.
"Those that jail us in a women's prison also investigate the complaints. So women don't trust that process and will not necessarily come forward ... because of fear of reprisal," she said.
Dr Wendell Rosevear has worked as a prison doctor and now provides counselling services for rape victims.
He says men are vulnerable to sexual assault in prison too.
"I've seen people raped within the first day of being put in prison and that's part of testing, where do you fit on the hierarchy of the power game," he said.
"The shortest timeframe I've seen from someone being a victim to go and become a perpetrator is six months."
Dr Rosevear and Sisters Inside are part of a growing movement calling for an independent prison watchdog to be established.
They say it will help stamp out sexual and physical abuse in Queensland jails and ensure inmates can report assaults.
The Human Rights Law Centre's Ben Schokma says the Queensland Government has a responsibility to consider the move.
"There's no point having a complaints-based system about correction staff when you have to complain to those very correction staff," he said.
"This system of independent monitoring will [serve] to prevent ill-treatment from happening in the first place, but most importantly it'll also be an important step to ensure the place of detention are more open, they're more transparent and therein accountable to actually prevent ill-treatment from happening in the first place."
Ms Kilroy says the unit that currently handles complaints from prisoners is part of Queensland Corrective Services.
She says the State Government should follow Western Australia's example and establish an independent authority.
"If the community understood and knew what was occurring inside our prisons they would be absolutely outraged," she said.
"That's why we argue for an independent chief inspector of prisons similar to the position in Western Australia, because they have the mandate and the legal framework to walk into a prison at any time and investigate."
Queensland's Police Minister, Jack Dempsey, was not available for an interview.
In a statement, a spokeswoman says there are a number of mechanisms for prisoners to report allegations of sexual assault or other mistreatment.
She says Mr Dempsey is currently in discussions with the Corrections Commissioner to review how the system can be improved.
