If you don't have it done in the financial year they turn 4, you won't recieve your supplement payments if elegable. I had DS's done, but didn't know I was supposed to inform c'link. I thought I was supposed to recieve paperwork about it or something, so I could pass on a number. But I got nothing.
I didn't worry much since my online services said I had til sometime in 2013 to do it. But I recieved my supplement payments last week & if I hadn't questioned the amount, I wouldn't have know that I wasn't going to recieve my $720 odd for DS.
So if you're getting FTB (A?) make sure its done & that centrelink is informed
