Justice advocates have called for inmates in Queensland prisons to have NDIS access after a report highlighting the "devastating" experiences of disabled people in the criminal justice system was seemingly buried by the Department of Justice and the Attorney-General.

On Wednesday, Guardian Australia revealed a previously unpublished report, commissioned by the Department of Justice and Attorney-General in 2022, contained allegations of police brutality and raised concerns "police actions could lead to escalation of behaviour in a person rather than de-escalation".

It also covered a series of encounters between disabled people and the criminal justice system, including alleged abuse, hostility, and over-policing.

The report was compiled by university academics but was never released, with the department denying it was covered up, arguing they regularly commissioned reports that were "not necessarily proactively released".

It was reported that part of the 40 recommendations mentioned in the academic report, one was the need to develop a state disability justice strategy to better support, assess, and recognise disability within the system.

It included testimony from a 15-year-old First Nations man with a psychosocial disability who was slammed to the ground by police and never charged, whilst another person was stripped naked and held in a cell because they viewed him as suicidal.

Debbie Kilroy from the National Network of Incarcerated and Formerly Incarcerated Women and Girls (National Network) said the reports were "sadly" not something they were hearing for the first time, especially in relation to allegations of police brutality and people being interviewed without an independent third party for support.

She said many women who displayed signs of "psychological distress or report any psychiatric issues" often received inadequate care.

"Many are subjected to solitary confinement, with the prison justifying the confinement as 'medical isolation'," Ms Kilroy said.

Noting the National Networks visits to a number of prisons across the country, Ms Kilroy said they continued to hear stories of incarcerated women facing challenges in accessing health care to maintain their physical and mental health.

"This practice is tantamount to torture and further harms the mental and physical well-being of these women," she said.

"Denying disabled prisoners essential health care because of their criminal status is an abrogation of the state responsibility to keep all of its citizens safe."

Queensland has come under fire for its treatment of prisoners - especially young people - many of whom are housed in adult watch houses.

Earlier this year, the state Death Review Board highlighted the case of two Indigenous children with serious disabilities who were kept in isolation for significant periods of time whilst kept in youth detention.

They both died in the immediate aftermath of their release.

The National Network called on all prisoners to have access to the National Disability Insurance Scheme (NDIS).

"The lack of support within the prison system is stark and the consequences are devastating," National Network member Tabitha Lean said.

"Women with disabilities face significant challenges in accessing the same kinds of disability support available to those in the community and are therefore left to navigate their conditions without proper assistance, leading to deterioration in their health and well-being."
