Support services for vulnerable kids are non-existent in parts of regional Queensland and police are the only round-the-clock option, a hearing on raising the criminal age of responsibility has been told.
Monday's parliamentary committee hearing is investigating a Greens' bill to raise the criminal age from 10, the status quo across the country, to 14.
The lack of support services is one of the few points of agreement between state Greens MP Michael Berkman and Queensland Police Union president Ian Leavers.
"The QPU and all of Queensland's twelve and a half thousand police are completely against raising the age of criminal responsibility," Mr Leavers said on Monday.
"Often the only services available in regional and remote Queensland are the police, other agencies are non-existent or are barely there."
Despite the QPU's general opposition to the bill, Mr Berkman said he was in "ferocious agreement" that police can't be expected to "step into the fray and to offer the whole gamut of support".
"(The children) have backgrounds of disadvantage and poverty, disengagement from school, diagnosed or undiagnosed cognitive deficits or impairments...police aren't best positioned to address those needs and to support children," he said.
Current laws give police a "vehicle" to divert young people from a life of crime, and raising the age would take away that option, Mr Levers said.
"When they're in detention...they actually have people that care about them," he said, maintaining arrests were viewed as a last resort.
"Sadly there is no support for them when they are released."
However, in the worst case scenario, introducing kids to the criminal justice system at a vulnerable age can "rapidly accelerate the likelihood of them graduating to a lifetime of crime," child protection body PeakCare Queensland says.
"PeakCare joins the chorus calling for change following 76 submissions lodged with the Committee - 75 support raising the age with the position of the 76th unknown," Executive Director Lindsay Wegener says.
Mr Wegener has previously managed a youth detention centre and served as a director of the state's youth detention centres.
""Those who have been the victims of offences committed by children expect and deserve much more than a response that simply places children on a conveyor belt into the adult criminal justice system," he said.
