If you read the terms it is the dividend or the cash, not both.
"Tatts intends to pay its shareholders a fully-franked special dividend of 20 cents per share(subject to the availability of franking credits) immediately prior to implementation of the Transaction in lieu of part of the cash consideration. A fully-franked dividend of 20 cents per share would have approximately 8.6 cents per share of franking credits attached."
