Child Support Australia is an independent service provider for parents caught up in Australia's child support system. As well as advocating for reform, we offer a range of free services.

We help payers and payees, fathers and mothers. But our ultimate goal is for the children of Australia to be made better off. Children should receive direct support and appropriate indirect financial support from two dedicated, hard-working parents.
