50,000 you also should have been sent an entitlement form !
Too late for B/Pay ( B/Pay usually takes 48 Hrs to process between accounts.)
Unless you live within the Perth CBD, you will struggle to for proceeds arrival prior to the 3.00P.M. Thursday cut-off date 13th Dec 2012
Outside of Perth, overnight express would be the best & only chance for a pre cut-off date, delivery.
