A 41-year-old Aboriginal woman has died in hospital after suffering a "medical event" at Wandoo Rehabilitation Prison in Perth's south.
The woman, who died on Christmas Eve, had been on life support at Fiona Stanley Hospital since the medical event on December 21, a statement from WA's Department of Justice said.
The Department of Justice said its staff had facilitated and supported family members to spend time with the woman at the hospital until she passed away.
"I wish to offer my condolences to the family at this difficult time," Commissioner for Corrective Services Mike Reynolds said.
"I trust they took some comfort in being able to say their goodbyes."
According to the statement, prison officers and medical staff provided the woman with first aid before an ambulance arrived on December 21, with preliminary reports indicating there were no suspicious circumstances.
"As with all deaths in custody, police will provide a report to the coroner," the statement said.
Formerly Wandoo Reintegration Facility for men, the prison was converted in 2018 to Wandoo Rehabilitation Prison for female inmates as part of the WA government's meth action plan.
To be accepted, the prisoners must have a drug addiction associated with their offending, self-refer to the program and prove they were motivated to rehabilitate.
The Therapeutic Community Program at the prison is run by non-for-profit organisation Cyrenian House in conjunction with the Department of Justice.
According to the WA government, in 2020 it was Australia's first voluntary drug and alcohol rehabilitation program run in a prison.
