Since the Harker report was presented in 2015 reviewing the centre’s management, it has appointed a specialist in youth services, Human Services Minister Jacquie Petrusma said.

The specialist, appointed in January last year, received endorsement for a “change process” at the centre to consider governance, risk, safety, training, the need for a therapeutic model, and human rights of young people, she said.

“Ongoing training surrounding risk management and non-violent crisis intervention has been provided as well as training for youth workers and the leadership team across a range of areas; trauma-informed care, resilience through change and safety as well as enhancing skills in de-escalation,” she said.

A man last week was charged following an incident at Ashley Detention Centre in July, accused of assaulting two children at the facility, who were both under 17 at the time.

Police would not confirm if the man was an employee of the facility.

In July, shards of glass from broken windows were used in an incident between staff at Ashley and residents of the facility.

Three staff were injured and police attended.

Ms Petrusma on Saturday said a protocol was in place at the Ashley Detention Centre to ensure “appropriate and timely review” of all critical incidents, and to make sure staff were continuing to learn emergency response procedures.

“In addition, an update of the practice manual continues, more active communication has been provided to staff regarding continuous improvement opportunities and resident complaint processes have been strengthened, along with work on better communication of residents’ rights and responsibilities.”
