Upsized cashback, not the best deal but should be able to get 180 days mobile for $30 if it's honored on the $180 plan which is reduced to $130 ATM.
I've queried Shopback if this specific plan is eligible, I'll update in the post or comments if I get a confirmation.
Edit: cannot get a clear answer out of SB but per CDG's comment, it tracked at $100.
Details:
NBN Home internet (excluding BYO plans) - $150
Postpaid Mobile (Device & Plan) - $150
$180 Prepaid SIM (including eSIM) - $100
$350 Prepaid SIM (including eSIM) - $100



Beware - keep track of all the transaction, order ID and take a screenshot of the deal on the app.
Optus-Shopback tracking is very poor and they'll always fail to track the cashback. You have to raise it with Shopback, provide all the evidence and hopefully they will honour it.
They had this same offer during black friday. I was able to claim the actual shopback in Jan'26 but my friend was straight up denied.
