Child Support (Registration and Collection) Act 1988

An objection to a decision (other than an objection to an appealable collection refusal decision or a care percentage decision) must be lodged by a person within 28 days after a notice of the decision is served on the person.

An objection to an appealable collection refusal decision must be lodged by a person within 28 days after the decision first comes to the notice of the person.

For the purposes of subsection (1) or (2), if the person is a resident of a reciprocating jurisdiction, the person’s objection must be lodged within 90 days after the time specified in that subsection, instead of within 28 days.
