Are We Safe Yet? Experiments with “Adult Crime, Adult Time” in Queensland, Australia

Abstract

When the new “Adult Crime, Adult Time” laws were passed in Queensland, Australia, lawyers and scholars predicted they would not have the desired deterrent effect. However, in the year following the legal changes, there was a significant reduction in the number of children proceeded against by police, particularly for break and enter and motor vehicle-related offences. We consider why the Adult Crime, Adult Time amendments to the Youth Justice Act 1992 (Qld) were “successful” in reducing offending by children when other legislative amendments have not had the same effect. We also consider the broader consequences of the legal changes for children who continue to offend, and the “contagion effect” the Queensland laws have had on other youth justice systems.
