"The community doesn't want to see young people reoffending,"she said.
"If we send them to detention,if we lock them up and throw away the key,we know that they are almost guaranteed to reoffend.
"We can't continue to keep doing the same things over and over and expect a different result."

It says detention should only be used for the small number of children who posed a serious risk to the community,while children in detention should be provided with health,rehabilitation services and educational and vocational programs.
Police will be given more training on appropriate use of diversionary options,including warnings,cautions and referrals for restorative justice conferences and other services.
Queensland will also participate in a national review of the age of criminal responsibility,which is currently 10 years old.
