I dont get either (it's what happens when you procreate with a d*ck) but I have always been led to believe that child support impacts your FTB entitlements.
Yes unfortunately I am suffering from procreating with a d*ck also. His measily $40 a month wouldn't hurt my FFB much except I received a large sum of money this financial year due to almost 9years of his not paying and the debt rising. So really it didn't help at all as all it means is I now am not entitled to FFB.

Thanks for your replies.
