All orders cease when the child turns 18 years, marries, enters into a de facto relationship or is adopted by another person [Family Law Act 1975 (Cth) ss 65H(2) and 65J(2)].
An order can be varied at any time, but unless there has been a significant change in the circumstances of either of the parents or the child, the court is generally reluctant to change existing orders except by consent of the parties.
