$24 Cashback on Everyday Mobile $40/M 55GB/M 5G SIM Plan (110GB for First 3 Months, $36/M with Everyday Rewards) @ ShopBack

If you’re running low on data in your mobile plan on your dual SIM phone, or you use a mobile as your broadband modem, this is cheaper than NBN (and capped at 150Mbps, better than most goo). And if you already use Everyday Mobile on your phone, you can gift yourself the remaining unused data so it doesn’t go to waste.
