Thanks girls
AnnaT, I don't recieve the $600 per child lol, I remember a friend mentioning it to me the other year and I was like 'HUH?! YOU GET PAID $600 FOR EACH KID?! HOW DO I GET THIS MONEY!?' but she knows jack-all about tax and FAO so she could only tell me she gets it, somehow lol. So I have to lodge a tax return to get that? I would be eligible even if I haven't earned a cent other than my FTBs? Lol again, $600 a year is nothing to sneeze at, I wouldn't mind finding out more about that one (but I've noticed that the Centrelink people I get hold of seem to be reluctant to discuss things you don't know much about, like they're acting dumb so you don't figure out you are eligible for more money!).

But silly me should have just checked the FAO website, I have an account on there so it's easier for me to update details etc without sitting on the phone for an hour and a half at a time... I just had a glance at it then and it tells me my next payment will be tomorrow (my regular fortnightly payment), and then the $900 stimulus payment will be in there on Wednesday. So, I assume that I *don't* need to lodge a tax return or update our details (my bank account details have been the same since we had DD, but my address has changed a couple times, Centrelink is up to date with my address but yeah, tax office doesn't know I exist probably hahah), and that because I get paid early this week I get the bonus the day it starts, if that makes sense.

So, sorry to be a pain and ask all those questions hahaha, but hopefully that new bit of info helps those who had questions of their own, cheers for giving me a hand, especially BG!!
