Just looking at the bb page on the human services website.
from the website
If your child was born or adopted before 1 July 2013, Baby Bonus is $5,000.If your child was born or adopted on or after 1 July 2013 (or you became eligible for Baby Bonus on or after 1 July 2013), Baby Bonus is either $5,000 or $3,000 depending on your situation.
You can get the $5,000 payment if your child is the first child you or your partner have given birth to (excluding stillbirth), adopted, or had entrusted to your care within 26 weeks of birth. Otherwise, you can get the $3,000 payment.
Baby Bonus is not taxable.
silly question, but does this include Dp's daughter? He hasn't given birth to her, but im just not sure if this would include her and mean we would get $3000 instead of $5000
