This deal popped up on my Facebook as advertisement.
I don't know whether it can be combined with Shopback and Cashrewards who are both offering $112 cashback.
You will receive a one-off bonus bill credit of $250 on your first electricity bill and $250 on your first gas bill (a total of $500 for gas and electricity), provided you have not received a welcome credit from us in the past 12 months. This credit includes GST and is not redeemable for cash.
