Does anyone know anything about this? Please help.

We paid the rest of our fees at the local preschool today as it was DS1's last day for the year and the office lady said something about a Child care rebate that we're entitled to.
DP was the one who was told about this and he's a little sketchy with details most the time so I was wondering if anyone knows anything about this Child care rebate.

How much is it roughly?

Thanks in advance.
I really appreciate it.
