Government policy must address the "villains" causing harm to children who end up in a fundamentally broken protection system, the head of a child safety inquiry says.
The probe into Queensland's child safety system - the third of its kind since 2003 - held its final hearing on Thursday, before Commissioner Paul Anastassiou KC hands his report to the government on Friday.
Mr Anastassiou said he hoped the inquiry's outcomes could help focus government policy and action on the causes of harm to children.
"They are alcohol abuse, drug abuse, domestic violence, and mental health issues," he said.
"They are villains who, in concert, are nearly always present when a child is removed into the care of the state."
The inquiry had given a platform to the voices of children "so their stories may be heard by those in a position to … fix the child protection system that is fundamentally broken", he said.
