Boost Mobile Deals Australia

You're getting a solid 80GB prepaid SIM for just $12, and after the $5 cashback it drops to $7 — a big saving on the $39 price.

• Must activate the SIM within 30 days of purchase
• Buying multiple SIMs? Do each as a separate transaction, or the cashback may not track
• Cashback isn't valid on eSIMs, recharges, phones, bundles, accessories or $2 SIMs
• If you want an eSIM, order the physical SIM first, activate it, then convert it in the Boost Mobile app — you'll need to pop it in a phone to get the authorisation SMS
• Nothing in the current T&Cs voids your cashback if you switch away after 28 days

You can grab the Boost Mobile $300 prepaid SIM for $242 delivered, saving you $58 off the usual price.

• SIM stays valid for activation until 24/06/2028
• Adelaide shoppers can choose free local pickup at Shop3, 85 Grote St
• Sale runs until 09/11/2026 or while stocks last

• Works with your existing unlocked phone, so no need to buy a new handset
