No, its only $7000. She may be confused because there was a FHOG years ago of $14000, i think it was back in the John Howard days. It was to boost the market for a while i think.
We actually got $11000, in december, because we live in a rural area and bought a brand new home. So i think there are some exceptions. Your bank or mortgage broker will tell you for sure.

Have fun house shopping!
