Vulnerable female inmates will need to wait for more security cameras to be fitted at a Sydney correctional centre where a prison guard committed multiple rapes and sexual assaults.
An inquiry into former guard Wayne Astill's crimes while working at Dillwynia Correctional Centre has heard that internal security failures allowed his assaults on nine women to take place.
The independent probe, set up after Astill's sentencing, previously heard more than 300 extra cameras were needed to address security shortfalls in the section of the prison where his offending took place.
But NSW Corrections Minister Anoulack Chanthivong said he would not act on any recommendations from the inquiry until the government received its official report, due next month.
He told a budget estimates hearing any measures to improve safety inside correctional facilities will be considered after ex-judge Peter McClellan delivered his findings in mid-December.
Greens MP Sue Higginson said video cameras provided fundamental protection for employees and inmates.
"We know it works in police stations," she said.
"We know this is a real genuine mechanism and measure for safety and security of some of the most vulnerable people in the state to whom you owe a duty of care."
Mr Chanthivong said he was "shocked and disturbed" upon hearing of Astill's crimes, but he would wait before considering any further action.
"Once (Mr McClellan's) report and recommendations are put forward to the government, we will carefully consider it," he said.
When asked whether there had been an audit of the camera system throughout NSW prisons, the minister was unable to provide a response but said he would take the question on notice.
Ms Higginson called for a broader inquiry to examine the "entrenched and systemic failures" within the corrections system.
"(Astill) was supported by an entire culture and system to enable some of the most harmful behaviour imaginable in our correction system," she said.
Astill will spend at least 15 years and four months behind bars for abusing his position of authority to commit offences over several years until his suspension in 2019.
