Eighteen year old children extending a child support assessment 277-03080000



This document outlines the process for dealing with applications to extend child support for a child after their 18th birthday.

Extending a child support assessment when a child turns 18

A carer entitled to child support for a child who is turning 18 years of age can apply to have their child support assessment extended (including an assessment based on a child support agreement) provided the child will be in full-time secondary education on their eighteenth birthday.

The child support assessment can be extended until the last day of the secondary school year in the calendar year in which the child turns 18. This includes periods prescribed by the school to be a term, semester or school holiday break, and where it is intended that the child will continue their secondary education after the end of the holiday.

A parent who has a relevant dependent child who is turning 18 years of age can apply to have this child taken into account in any applicable administrative assessment provided the relevant dependent child will be in full-time secondary education on their 18th birthday, consistent with that described for child support children turning 18.

A secondary school includes a school, TAFE College or any other educational institution that provides full-time secondary education. A secondary school also includes a school that caters for the needs of children with learning difficulties and provides a form of education that is not tertiary education.

The Resources page contains links to a table of Australian state/territory Department of Education websites, additional resources about extending a child support assessment for a child turning 18 years of age and links to manual letters.
