Optus Deals Australia

If you're a new Optus customer, you can score $300 cashback on a 5G Home Internet plan or $250 on an nbn plan when you sign up through ShopBack.

• Excludes BYO plans
• Minimum 90-day stay required
• nbn service starts as soon as you sign up, so you can't delay it

Worried about tracking? You can sign up with TopCashback and claim their Highest Cashback Guarantee instead.

You're getting a full year of Optus prepaid for just $249 — that's 350GB of data plus unlimited Aussie calls and texts, delivered to your door.

• The $350 starter kit auto-upgrades to a $395 plan, and you'll also score a bonus $39 Optus SIM
• 350GB on activation and your first two recharges, then 240GB — plus 40GB bonus data if you stay on AutoRecharge
• Includes 6000 mins of standard international calls to Zone 1 and 800 mins to Zone 2

One heads-up: the seller opens the packaging along the dotted line to photograph the SIM serial number before posting, so the outer sleeve will be opened (the SIM itself stays brand new and unactivated). If you're fine with that, this is a cracking value way to lock in a year of data.

You're getting a massive 100GB of data for just $6 out of pocket after $7 cashback — that's only $13 upfront for a 28-day Optus prepaid SIM or eSIM, down from $40.

• 100GB on activation plus your next two recharges (just set up AutoRecharge to lock it in), then 30GB ongoing
• New services only — activate by 07/04/27, and skip buying through chat, the My Optus App, or with gift cards or you'll lose the cashback

At 16.67GB per dollar, this is a cracking deal if you need a cheap data hit — just keep AutoRecharge on to stay on the plan.

You can score $80 cashback when you grab this Optus 365-day prepaid plan for $199 (normally $350) through ShopBack — that's 300GB of data for the whole year!

• Just $119 effective after cashback, working out to under $10/month
• Reports show cashback tracks within 30 minutes
• Available as physical SIM or e-SIM, but you must purchase online and activate within 28 days
• Heads up: keep your service active for 90 days post-activation to secure the cashback

This one's for new activations only, so if you're after a cheap year of data, don't sleep on it!

You're getting 12 months of Optus prepaid coverage with a massive 300GB on your first three recharges for just $189.99 at Costco — that's a serious saving on the usual $350 price tag.

• 300GB data on the first 3 recharges (then 220GB after that) — plenty for streaming, scrolling and hotspotting all year
• Unlimited standard national talk & text, plus 6,000 mins of international calls to Zone 1 destinations
• 365-day expiry so you set it and forget it — no monthly top-up stress
• Heads up: new Optus customers only, so if you're porting an existing Optus number you'll need to port out and back in
• In-warehouse only and Costco membership required — limit of 3 per member, and it's non-refundable

Grab this deal if you want a full year of big data without the monthly bill shock!

You're getting a massive $350 Optus prepaid credit for just $195 — that's a huge saving on a full year of connectivity, with zero lock-in contracts.

• Plenty of data: 300GB on your first 3 recharges, then 220GB for the rest of the year — perfect for streaming and daily use on Optus's 4G & 5G network.
• Bonus SIM trick: Includes a free Lebara $30 SIM so you can port out and back in as a "new customer" to unlock this plan — a smart workaround that saves you even more down the track.
• Great for calls: Unlimited standard Aussie talk & text plus 6000 minutes to Zone 1 international numbers and 800 to Zone 2.

Just a heads-up: the seller opens the pack to photograph the serial number before shipping, but the SIM itself stays brand new and unactivated. Stock is limited and the deal ends 16/09/2026, so grab it while you can!
