"The degree of physical punishment that a parent or carer can use with a child is subject to legal regulation in Australia. In most states and territories, corporal punishment by a parent or carer is lawful provided that it is carried out for the purpose of correction, control or discipline, and that it is "reasonable" having regard to:
the age of the child;
the method of punishment;
the child's capacity for reasoning (i.e., whether the child is able to comprehend correction/discipline); and
the harm caused to the child (Bourke, 1981)."
