I have found the online estimator extremely accurate You can also go look on the website in the "Parents" section (or is it 'Raising Children'... I can't remember), and look up the FTB A and B and also Parenting Payment, and look at the eligibility. There is claiming information on there too, although I'm pretty sure you can't claim until you've had the baby. I think these are the most common paymenst you can get after a baby is born. Maybe Rent Assistance too?
