Is there some reason to think she should be looking at top schools? You have no test scores? Her GPA is 3.8 as a sophomore, what sort of classes is she taking?
I would look at UQ as a nice state school, with great party potential. Not a top state school at all either. The international target market for UQ is (was) Asia and many of these students get a residency status after graduation, that in itself makes international rates a bargain. Not a real hook for a US citizen.
