Queensland will launch a thorough examination of the state's foster care system in the wake of the death of 12-year-old Tiahleigh Palmer.
Police have recently excavated the home of Tia's foster family, where she was allegedly killed 11 months ago. Police allege that Rick Thorburn murdered Tia while under foster care in his home.
Thorburn's 19-year-old son Trent has been charged with incest.
Speaking on Sunday, Premier Annastacia Palaszczuk said the state's family and child commissioner would work with an expert panel on an examination of foster system following what she described as an "absolute tragedy".
"The panel will help develop and support the implementation of recommendations to improve foster care and blue card systems," Palaszczuk told reporters in Queensland.
"We do have a vigorous system to approve foster careers and blue card holders, but where we can make improvements in that State, we absolutely will.
"We will also work with other States to have a proposal for a national reportable conduct scheme to improve how we respond to allegations of child abuse and neglect across our borders."
The Premier said former Queensland Police services commissioner and ethical standards commander Paul Doyle, and Foster Care Queensland executive director Brian Smith would be among those to sit on the expert panel.
Queensland Family & Child Commission boss Cheryl Vardon said the aim was to improve the system through "rigorous examination"..
"In this examination, we want to make sure that Queensland's children are more than safe," she told reporters.
"If we see something that needs fixing at any particular time or immediately, then we will make sure that we consult and ensure that that change happens."
