In the hearings deputy Labor leader Michelle O'Byrne asked Mr Jaensch whether the state government's Intensive Family Engagement Services initiative was failing.

She also asked whether support by the IFES, within Safe Families Safe Kids, was provided to the child who died and the child who self-harmed, including 20 hours of weekly support that the model was meant to provide.

"A child died under his watch, who was discharged from the hospital and supposedly in receipt of IFES, the question is whether or not that support was provided, and the Minister would know the answer to that question," Ms O'Byrne said.

"If I thought it might be a once off I would be less concerned but I am also aware of an incident in an investigation into a child who was supposedly being supported by your service, who still harmed in the most horrific manner."

Ms O'Byrne said a small number of cases were being investigated.

"It would appear from information that you are receiving that your intensive family support service does not work... as a result of these investigations, what advice did you receive, and can you confirm that they [kids in out of home care] were being supported by intensive support services, and if they were not, then you are culpable," she said.

Mr Jaensch said he could not comment on the particular cases.

"There is very little detail to go on and in the context of the seriousness of the cases that we are talking about, I am not going to give definitive answers without knowing the context of which cases are being referred to," he said.

"Disclosing any detail or features could lead to the identification of the children... and could inadvertently lead to contempt of the coroner's court, so again, I won't be presenting information in here."

Ms O'Byrne also raised concerns about the personal details of children in child protection being viewed by non-government organisations (NGOs) and the legality of that information sharing agreement.

The details of children could be viewed by relevant government departments, as well as NGOs such as Baptcare and Mission Australia.

Mr Jaensch said that the government had received advice from the Solicitor General as to the sharing information arrangement.

"The advice was not delivered to me. There is no evidence of deviation from the advice, or problems arising from it as a result."

Other questions related to Ashley Detention Centre, including that there were 204 searches on children at the centre during which no contraband was found and 101 instances where children were placed in isolation.
