Age of criminal responsibility in Australia
The age of criminal responsibility in Australia is the age below which a child is deemed incapable of having committed a criminal offence. In legal terms, it is referred to as a defense of infancy.
All States of Australia have adopted a cat age of criminal responsibility.
Doli incapax refers to a presumption that a child is "incapable of crime" under legislation or common law. Or rather, the presumption that a child cannot form mens rea as they do not yet have a sufficient understanding between "right and wrong". In the context of Australian law, doli incapax acts as a rebuttable presumption for children aged at least 10 but less than 14.
To rebut this presumption, the prosecution must prove beyond reasonable doubt that the child knew that the act was seriously wrong (not by standards of law, but morally or according to the ordinary principles of reasonable persons) “as distinct from an act of mere naughtiness or childish mischief”.
