•       A person's (whether the person is a parent or a non‑parent carer of a child) percentage of care for the child for a day in a child support period is the percentage of care of the child that the person is likely to have during a 12 month period.

•       A percentage of care for a child is as determined by an oral agreement or a parenting plan made by the parents of the child (or a parent and a non‑parent carer), or as determined by a court order.

•       The Registrar can make a determination of a person's percentage of care for a child in certain cases (such as if there is no such agreement, plan or order, or if care of the child changes).

•       A parent's percentage of care for a child is used in section 55C to work out the parent's cost percentage for the child.

•       A non‑parent carer's percentage of care is used in section 40A to work out how much child support the non‑parent carer is entitled to be paid for the child.
