You should ask her to talk to her university immigration officer/help person. I went to Victoria university and after graduated, they lodged my application for my study to work visa and they had all the answers to all of my questions . Surely they'll know some info/can possibly help her out - each Uni has someone who looks after the international students! Also, try ringing immigration if you haven't already, they are quite helpful and open 24/7 so you can maybe get soooooome ideas there on options? But I'd highly recommend that she gets in touch with the uni's immigration rep!!
