Queensland's acting premier has defended the state's handling of the Tiahleigh Palmer case, saying it had closely followed the advice of police on the matter.
The state's foster system is facing heavy scrutiny after murder charges were laid against the schoolgirl's foster father.
"What we've done is paid very close attention to police advice all the way along," Acting Premier Curtis Pitt said on Thursday.
"We have listened to what police have told the government and, of course, individual agencies have acted within their protocols."
It has emerged that Tiahleigh's foster family operated a day care centre until their approvals were revoked in April when police alerted the government to alleged criminal activity.
Mr Pitt said while he was distressed by the circumstances in the case, it was now up to justice to take its course.
The government on Wednesday announced a six-month review of the state's blue card system in light of the charges laid against Tiahleigh's foster family.
The 12-year-old's foster father, Rick Thorburn, 56, has been charged with murder and interfering with her corpse, while his son Trent, 19, is facing charges of incest, perjury and attempting to pervert the course of justice.
His wife Julene, 54, and older son, Josh, 20, have been charged with perjury and attempting to pervert the course of justice.
The Thorburns were approved as Tiahleigh's carers in August 2014.
The Marsen State High School student vanished in October last year, with her body later found on the banks of the Pimpama River.
Child Safety Minister Shannon Fentiman has said all checks around blue cards, criminal history and references were undertaken as well as mandatory training.
The Liberal National Party (LNP) opposition has called for a full-blown independent inquiry into the child safety department and the state's foster system.
But Mr Pitt has rejected those calls, saying the former LNP government had already undertaken a full-blown review and those outcomes were being implemented.
