Underneath The Radar,
Mate have another read of the deed. It clearly states that if QF arent happy with you and dont offer you employment at the completion of GFS, no bill will be given to the applicant. i.e. in the case that they dont want you, you dont need to pay the money back. You only need to pay it back if you withdraw on your own accord or leave before the four year bond is completed.
Cheers.
