if he recives anything from centerlink, child support will(at least they shouls) ask her if she wants them to sort it out, or if they have personal arrangements. my cousin recives i think its $5 a week from her sons "donor" and has since the day he took her to court for visitation he never used. it is taken from his centerlink befor he recives it. im certain it has been this way since he was 6 months old, hes just turned 5. hope this helps.
