Can't remember about the actual paperwork, but with DS I remember that I got my FTB one week, and the Baby Bonus the next week, and they were fortnightly. So perhaps I got them on different paperwork, but to be honest I can't remember.

I haven't got the Baby Bonus for DD yet due to some hassles with Centrelink and our Tax having only recently been done. I didn't think that tax and salary had anything to do with the Baby Bonus, but apparently they still decided to hold the Baby Bonus until it's all done. It's just been finalised so I'm going to have to call Centrelink and hope that getting it all sorted won't be an issue (as I even had to pay back some money that's actually owed to me as I couldn't "prove" I deserved it).
