The Queensland government has initiated a commission of inquiry into its failing child safety system, which incurs an annual cost exceeding $1 billion.

This inquiry, led by Paul Anastassiou KC, aims to tackle critical issues of crime, abuse, and neglect affecting children in care.

Concerns have been raised as more than 100 serious youth offenders are reported to be living in out-of-home care, questioning the system's effectiveness in managing high-risk children.

Child safety minister Amanda Camm highlighted the necessity of investigating how the care system may inadvertently contribute to criminal behavior among youth offenders.

Recent census data reveals alarming statistics, with 11% of children entering out-of-home care having experienced sexual abuse, 46% facing physical abuse, and 88% suffering from neglect.

Children who enter care before the age of ten often face worse outcomes, including mental health issues, self-harm, disabilities, and limited intellectual functioning.

Educational challenges are evident, as 61% of children in residential care have been expelled or suspended from school.

The Crisafulli government is committed to implementing significant reforms, asserting that previous leadership has neglected the system, resulting in thousands of children being let down.

The government disclosed that the annual cost of care for some teenagers can soar to $2.6 million, attributing this financial burden to past Labor administrations.

Currently, over 12,500 children are in out-of-home care in Queensland, with the system projected to cost $1.12 billion in the current financial year.
