In all Australian jurisdictions, the age of criminal liability is 10. This means that no child below the age of 10 can be arrested, summonsed or found guilty of a criminal offence. In New South Wales, this rule is contained in Section 5 of the Children (Criminal Proceedings) Act 1987. Children between the ages of 10 and 18 who are charged with criminal offences are dealt with by the Children’s Court. Get More Info on The Age of Criminal Liability in NSW
