I am not sure, but I don't think her father's case has anything to do with her. In this country, after 18 years people leave on their own and they are not responsible for anything their parent's has to do with so I doubt she will et trouble on that.

Also when she is flyng to US or Australia, on the port they will run  her fingerprint to see if she is admissible or not/ If she has done any crimes. I don't think  it matters because of her father's inadmisibility.

Goodluck!
