Copied from previous post:
Note that the starter packs are just credit, so they can be used towards any prepaid plan. Best Ozbargainer value is to get 15GB/6 months service for $30:
Go via CashRewards or ShopBack to get $5 credit
Buy $40 credit for $20
Add additional $25 credit to get the $65 6 month plan
Put in referral code (from a mate or the OzB randomiser) in the Woolworths Mobile app to get a $10 WISH GC (gift cards sent only after staying for at least 3 active months)
Total spend = $20 + $25 - $5 cashback - $10 WISH card = $30
Edit:
Cashback valid for physical AND eSIM through CR.
Cashback valid for eSIM only through SB.
Thanks Junk Sifter!
Detailed steps for this
Would be good for 5 months of 10% off groceries
