Hey Linda, it's not as confusing as you think

Have a look on the centrelink website. It is laid out really well and almost everything has been explained in easy to understand terms.

There is an online estimator which is very simple to use. You put in your birth dates, babys birth date (just put todays date), your incomes, whether you rent or not, and a few other foreign income questions.

They will then tell you how much PPP (parenting payment partnered) and how much FTB (family tax benefit) you will be entitled to. It will also tell you if your DH will receive any PPP as well. (WHich I think he should considering he is running at a loss)

If you are not currently working, you may be entitled to another payment before the bubs arrives. That would most likely be NEw Start Allowance in your case. This was formally known as the dole.
They may insist that you apply for jobs in this time, but I think the need for applying ceases at approx 34 weeks gestation.

HTH a little bit.

Hopefully BG will have some time over the next few days to give you some more info.
