Optus

Joining Optus? Pick your plan, then sign up through ShopBack before you pay: ShopBack Cashback works like a discount, only easier than a promo code. Optus is Australia's second-largest telco and a subsidiary of Singtel, the Singapore-headquartered telecommunications group. It sells mobile plans (SIM-only, phone-on-plan, mobile broadband), home internet on the NBN and 5G Home Internet, prepaid recharges, and small-business connectivity. It also runs Optus Sport (Premier League, European football and rugby coverage), the SubHub bundle for streaming subscriptions, and the Optus Perks loyalty programme. Activate ShopBack Australia at shopback.com.au/optus before clicking through so eligible sign-ups earn Cashback at the current published rate.

Optus sells SIM-only postpaid plans across small, medium, large and XL data buckets, phone-on-plan bundles that finance a handset over 12, 24 or 36 months, and mobile broadband for tablets and hotspots. Larger plans typically bundle Optus Sport and a SubHub credit; smaller plans focus on data and included international minutes. Verify current inclusions and pricing on optus.com.au before locking. Activate ShopBack Australia at shopback.com.au/optus first so eligible plan sign-ups earn Cashback at the current published rate.

Optus Prepaid runs three main shapes: daily, weekly and 28-day (monthly) recharges, plus a longer-term Choice Plus option for users who want to lock in a bigger data bank for a set price. Choice Plus tiers typically include unlimited standard national talk and text with a data bucket that lasts across the plan period. Prepaid is a good fit for shoppers who want month-to-month billing with no fixed-term contract or who share plans across a household. Confirm current recharge prices and inclusions on optus.com.au before locking.

Optus retails NBN across the standard speed tiers, typically NBN 25 (Basic II), NBN 50 (Standard Plus), NBN 100 (Premium), NBN 250 (Home Fast), and NBN 1000 (Home Ultrafast) where the connection type supports it. Home Fast and Home Ultrafast are only available on FTTP or HFC lines that meet the throughput criteria, so the tier you can actually order depends on your address. Optus 5G Home Internet is a fixed-wireless alternative in eligible suburbs and can be a strong pick where the NBN copper leg is slow. Verify tier availability by address on optus.com.au before locking.

Optus Sport is a subscription streaming service focused on Premier League, European football and rugby coverage, and it is typically included with selected Optus mobile and home internet plans (verify current rights and inclusions on optus.com.au). Optus SubHub is a bundling engine that lets you pay for multiple third-party subscriptions (Netflix, Disney+, Paramount+ and others) in one Optus bill with a small bundle discount when you bundle two or more services. SubHub is useful for households already paying for multiple streaming services separately who would rather consolidate the bill and lift a small saving. Verify current SubHub partners and discount mechanics on optus.com.au before signing up.

Optus Perks is the loyalty programme inside the My Optus app, offering rotating rewards like movie ticket discounts, coffee vouchers, retail credits and occasional food or delivery offers to Optus mobile and home internet customers. It is most useful if you already spend in the categories in the current perks refresh. Perks come with your base plan and surface directly in the app, without a code.

Telstra is typically the pick for shoppers in regional and rural Australia because of its wider Outback and highway coverage footprint, though this typically comes at a price premium on comparable mobile plans (check current pricing on telstra.com.au). Optus is the stronger price-to-coverage balance in metro and major regional centres, and it wins on entertainment bundle value (Optus Sport plus SubHub credits) that Telstra does not directly match on its base plans. Pick Telstra if you regularly drive or work outside major population centres; pick Optus if you mostly use the phone in metro or coastal areas and want Optus Sport and SubHub included. See our Optus vs Telstra vs Vodafone vs TPG breakdown for a full network read.

TPG and Vodafone Australia merged and now share a single network, marketed under both brands and under felix mobile, which is TPG's low-cost MVNO. Vodafone and TPG typically undercut Optus on SIM-only pricing and lean on aggressive NBN promotional pricing (particularly on NBN 100 and NBN 250 tiers). Optus typically leads them on entertainment bundle value (Sport and SubHub) and on Perks refresh cadence. If you value bundled streaming and loyalty offers, Optus is the natural pick; if you want the cheapest usable SIM-only or NBN monthly bill, Vodafone, TPG or felix mobile are typically the sharper options. Verify current pricing on each provider before locking.

MVNOs (mobile virtual network operators) resell capacity on the big three networks at typically lower monthly prices in exchange for a lighter feature set. Amaysim runs on the Optus network and is a common pick for shoppers who want Optus coverage without the postpaid contract. Boost Mobile runs on the Telstra retail network and is the main way to access Telstra-network coverage at a discount. Kogan Mobile runs on the Vodafone network and typically sits near the lowest per-GB SIM-only price point in Australia (check current pricing on kogan.com/au/mobile). felix mobile is TPG's MVNO on the Vodafone/TPG network with a single-plan structure and an environmental positioning. Optus retail plans win over these MVNOs when you specifically want Optus Sport, SubHub credit, or Perks; the MVNOs typically win on straight-line dollar cost per month if you only need talk, text and data. Kogan Mobile has its own ShopBack Australia merchant page at shopback.com.au/kogan.

Optus phone-on-plan bundles a handset (iPhone, Samsung Galaxy, Google Pixel and others) on a 12, 24 or 36-month device repayment alongside a SIM-only plan. The handset repayment is separated from the plan cost on the bill and is typically interest-free over the term. Buying the phone outright from a retailer like JB Hi-Fi or Officeworks and pairing it with an Optus SIM-only plan is usually cheaper on total spend but requires the upfront outlay. Phone-on-plan is a good fit for shoppers who want the cashflow smoothing and are willing to stay on the same telco for the device term; outright plus SIM-only is the sharper option for shoppers with cash on hand who want plan flexibility. See our JB Hi-Fi iPhone comparison at shopback.com.au/blog/finance/apple-au-vs-jb-hifi-vs-officeworks-iphone-2026 for the outright side.

Optus does not sell a formal single-line family bundle; the practical equivalent is running multiple postpaid SIM lines on one Optus account with SubHub for shared streaming across the household. Larger postpaid plans typically include Optus Sport and a SubHub credit that the whole household can use, so the family value comes from the entertainment inclusions rather than a per-line multi-plan discount. Households already paying for two or three streaming subscriptions separately typically get the strongest value from consolidating them under SubHub while running Optus mobile on multiple lines.

Switching between Australian telcos is a mobile number portability (MNP) process regulated by the ACMA. Sign up for the Optus plan you want, provide your existing mobile number and current provider, and Optus initiates the port. The old service usually stays live until the port completes (typically within a few hours, sometimes up to a business day). Cancel any AutoPay on the old service after the port completes to avoid a stray charge. Start from the ShopBack Optus page before you sign up, then order the plan as usual.

Check address availability on optus.com.au; the checker returns your line technology (FTTP, HFC, FTTN, FTTC or Fixed Wireless) and the top NBN tier that address supports. Pick your speed tier and pay any once-off connection or hardware fee if applicable. Optus typically ships a modem-router; installation may require a technician visit for a new FTTP or HFC line. Once activated, keep the plan on the same address for the minimum Cashback-eligibility window per current terms.

Optus 5G Home Internet is a fixed-wireless product on Optus 5G towers, delivered via a plug-and-play modem with no NBN co install. It can be a strong pick where the NBN line at your address is on slower FTTN copper, or where you want to skip a technician visit. Speed varies by tower distance and time of day, versus NBN which is contracted at a nominal tier. NBN is typically the more predictable pick for heavy-usage households; 5G Home is typically the sharper pick for renters, short-term addresses, or FTTN-limited streets. Verify 5G Home coverage by address on optus.com.au.

Optus typically runs its deepest annual mobile and NBN promotions across End of Financial Year (late June through July), Boxing Day, and Black Friday and Cyber Monday (last Friday of November through the following Monday). Back-to-school (January) typically brings student and family plan campaigns, and the Optus Perks refresh cadence brings rotating retail and entertainment offers throughout the year. Plan-specific promos (bonus data, waived setup fees, gift cards on sign-up) run rolling outside these headline windows.

Looking for an Optus promo code? Pick your plan, then sign up through ShopBack before you pay: ShopBack Cashback works like a discount, only easier than a promo code. Optus's direct-site pricing typically applies any current campaign discount at checkout without a separate promo code, and sign-up bonuses (bonus data, waived connection fees, gift cards) are typically auto-applied to eligible plans during the promo window. Start from shopback.com.au/optus.

Sign in to ShopBack Australia, click through to Optus from the merchant page at shopback.com.au/optus, and complete the sign-up on optus.com.au. Cashback then goes to your ShopBack account, and the current Cashback is shown on the Optus page on ShopBack before you sign up. Eligibility is typically new-customer or new-service, and the sign-up usually needs to remain active for a minimum period before Cashback confirms.

Pending Cashback on Optus sign-ups typically appears in the ShopBack Australia app within the tracking time published on this page, and confirms after the service has remained active through the confirmation time per current Optus terms. Check this page for the current tracking and confirmation times.

For metro and major regional Australian households, Optus is typically a strong price-to-coverage pick, particularly for shoppers who value bundled Optus Sport and SubHub credit alongside the mobile or NBN plan. Regional and rural shoppers typically get more coverage headroom on Telstra; cost-first shoppers typically save more on Vodafone, TPG, felix mobile, Amaysim, Boost Mobile or Kogan Mobile MVNOs. On value, an Optus plan sized to your actual data usage, timed to an EOFY or Black Friday sale window, and activated through ShopBack Australia at shopback.com.au/optus for the current Cashback rate is typically the strongest net-cost route for shoppers who want Optus specifically.

The current Cashback is shown on the Optus page on ShopBack.

Yes. ShopBack Cashback on an Optus plan sign-up only tracks against a signed-in ShopBack Australia account, so the click-through from the ShopBack Optus merchant page is tied to your member ID. Registration is free at shopback.com.au/signup and takes under a minute. Sign in first, then open the ShopBack Optus page and click through to optus.com.au to complete the plan sign-up, and Cashback lands in your account at the current published rate.

Yes. Optus supports eSIM activation on eligible iPhone and Android handsets across postpaid and prepaid, letting you activate the plan digitally without waiting for a physical SIM to ship. eSIM is useful for travellers pairing a domestic Optus line with an international travel eSIM, and for shoppers switching networks who want to avoid a SIM-swap delay. Start the plan sign-up from shopback.com.au/optus to earn Cashback, then activate the eSIM in the My Optus app after the port completes. For a deeper look, see Pre-Order iPhone 18 in Australia: JB Hi-Fi vs Amazon vs Officeworks vs Optus.

Optus postpaid bills run on a monthly cycle set from your activation date, with a bill issued a few days before the direct debit. You can upgrade or downgrade the plan mid-cycle in the My Optus app; upgrades typically apply pro-rata inclusions from the switch date, while downgrades usually take effect from the next full billing cycle. Prepaid recharges run independently of any billing cycle since you top up as needed. If you plan to switch to Optus from another telco, activate ShopBack Australia at shopback.com.au/optus before signing up so eligible new sign-ups earn Cashback at the current published rate.

Optus sells daily and weekly International Roaming day passes that give a set data, talk and text bucket across most popular travel destinations, activated automatically when you land or manually via the My Optus app. This is typically simpler than pay-as-you-go roaming but can cost more than a local travel eSIM for longer trips. For short weekend hops to Bali, Fiji or New Zealand the day pass is usually the sharpest pick; for multi-week trips a dedicated travel eSIM alongside the Optus line is often cheaper. Verify current roaming zones and daily pass pricing on optus.com.au before departure.

Go through the ShopBack Optus merchant page before you sign up, and the Cashback goes to your ShopBack account once the plan is active.

Start from the ShopBack Optus page in the ShopBack app, on shopback.com.au or via the ShopBack browser extension, and complete the new-service order online on optus.com.au. The Cashback then goes to your ShopBack account once Optus validates the new service. Cashback is a fixed amount per new service rather than a percentage of your bill, and it is paid once per order regardless of how many plans or SIMs are on it.

The ShopBack Optus page carries three things. First, Cashback: a fixed amount per eligible new service, shown by category on this page (nbn Home Internet excluding BYO-modem plans, 5G Home Internet, Postpaid Mobile with device and plan, Postpaid Mobile SIM only, and Prepaid SIMs at the A$39, A$40, A$49, A$59, A$180 and A$350 price points), paid after confirmation. Second, gift cards: there is no discounted Optus gift card or ShopBack swap card for Optus on the ShopBack gift card hub at shopback.com.au/gift-cards as of this date. Third, an upsize: when an upsize runs, the higher rate shows on this page as an Upsized label next to the category.

Work it as first-year plan cost minus the fixed Cashback amount shown on this page. Because the Cashback is a flat amount rather than a percentage of your bill, it is proportionally bigger on a cheaper plan. Read the live amount for your category on this page before you order; it is paid to your ShopBack balance after confirmation and can be withdrawn to your bank account or PayPal. Check the plan price on optus.com.au for the current figure.

Yes, on new activations. Optus's own prepaid range is sold as Flex Plus recharges plus long-expiry options, so match the SIM you buy to a price point listed on this page.

Optus Perks is a loyalty programme you use after the service is live, and SubHub credits on selected Optus Plus Promo plans are plan inclusions rather than discounts applied at checkout. Optus's standard in-market promo plans are the advertised price on optus.com.au. Go through ShopBack before you pay and the Cashback tracks to your ShopBack account.

Confirmed Cashback sits in your ShopBack Australia balance and can be withdrawn to an Australian bank account or to PayPal from the ShopBack app or website. There is no minimum spend on Optus, and the amount is fixed per new service and paid once per order regardless of how many SIMs or plans that order contains. Expect the Pending to Confirmed step to take a while on Optus because the service has to stay connected first; the confirmation time is shown on this page.

The ShopBack browser extension works on Optus: activate it when you land on optus.com.au and it works the same way as going through the ShopBack Optus page.

Looking for an Optus promo code? Pick your plan, then sign up through ShopBack before you pay: ShopBack Cashback works like a discount, only easier than a promo code. Optus does not run coupon codes on optus.com.au; its deals are promo plans priced in the cart. Optus promos usually take the form of plan offers for new services, such as a bigger data bucket for the first 12 months, home internet discounts for 12 months and savings when you add nbn to a mobile account. Start from the ShopBack Optus page before you sign up, and the fixed Cashback amount shown on this page comes back once the plan confirms.

MVNOs resell the big three networks at lower monthly prices with a lighter feature set. Amaysim runs on the Optus network, so it is the pick if you want Optus coverage without postpaid and do not need SubHub or Perks. Boost Mobile runs on the full Telstra prepaid network and is the pick for regional coverage on a prepaid budget; its 28-day plans ran A$28 to A$74 as listed on Boost's site in October 2026. Kogan Mobile and felix mobile run on the Vodafone and TPG network and compete on per-GB price. Optus retail wins when you want 5G at no extra cost on Choice Plus, data sharing, the Family Plan, SubHub credit, or phone-on-plan financing. Amaysim, Boost Mobile, felix mobile and Kogan each have their own ShopBack pages.

Optus's Choice Plus SIM-only range is month to month with no lock-in, in Small, Medium and Large sizes, plus Promo Plans for new services and student versions. All include 5G access on a compatible device and Endless Data, which drops speed to 1.5Mbps after the allowance instead of charging excess. Check optus.com.au for current sizes and prices. A new SIM-only sign-up through the ShopBack Optus page earns the Postpaid Mobile SIM Only Cashback amount shown on this page.

Three 5G Home Internet plans were listed on optus.com.au in October 2026, all unlimited data on new services with pricing for 12 months then the standard fee: Everyday 5G at A$54 then A$69 (50/11Mbps typical busy period), Everyday Fast 5G at A$64 then A$79 (87/15Mbps), and Entertainer Superfast 5G at A$84 then A$99 (230/20Mbps). A 4G Home Internet plan was A$44 then A$59 in select areas (as listed on Optus's site in October 2026). The 5G modem is credited at A$13 a month over a 36-month device payment plan (as listed on Optus's site in October 2026), so it costs A$0 if you stay; leave early and the remaining modem balance is payable. 5G Home Internet is its own Cashback category on the ShopBack Optus page.

The Optus Family Mobile Plan gives up to 4 SIMs for A$165 a month sharing 320GB, month to month, as listed on optus.com.au in October 2026. Households with more than four people can add up to four Optus Plus Kids data-share SIMs at A$29 each per month, and the plan includes a safety and parental-control app subscription that normally costs A$8.99 a month (as listed on Optus's site in October 2026). At A$41.25 per line for four lines (October 2026 pricing) it undercuts four separate Small Choice Plus plans at A$60 each by A$75 a month at standard pricing, though the 100GB for A$39 promo on single lines narrows that gap in year one. Cashback through the ShopBack Optus page is paid once per order regardless of the number of SIMs.

Skip Optus when coverage outside cities is the deciding factor: Telstra and Boost Mobile on the full Telstra network are the safer bet for remote travel and regional properties. Skip it when you only need a few GB a month, because an 8GB Boost plan or a small Amaysim or felix plan usually costs less than Optus's entry Choice Plus plan at standard pricing.

Yes, once per order. Cashback is paid once per order regardless of the number of plans and SIMs on that order, so a Family Mobile Plan order or a multi-SIM Choice Plus order earns a single fixed amount, not one per line. Every line is a new service for a new Optus customer.

Optus plan prices on optus.com.au are shown in Australian dollars with GST included, and you pay postpaid plans by direct debit from a credit or debit card or bank account after the monthly bill issues, while prepaid is paid upfront per recharge or via Auto Recharge. The online order requires ID, a credit card and employment details for a credit check. Cashback on Optus is a fixed amount per new service shown on this page.

Optus sets its own student, staff, Flybuys and regional discounts, and its student promo plan is verified by Optus. Start from the ShopBack Optus page before you sign up; the fixed Cashback amount for your category shows on this page.

The cheapest ongoing Optus mobile service is a prepaid Flex Plus recharge, and the cheapest postpaid entry is the Small Choice Plus SIM-only promo for new services. On home internet the entry point is the Basic nbn plan. Check optus.com.au for current prices. To go lower, start from the ShopBack Optus page and complete the order on optus.com.au as a new customer; the fixed Cashback amount for that category is shown on this page. Because it is a fixed amount, the saving is proportionally larger on a cheaper plan than on a Large plan.

Optus sets its own student, seniors and bundle offers. Optus does not publish a seniors-specific plan or discount on optus.com.au, so a senior ordering a standard Choice Plus plan is treated like any other new customer. Bundles are Optus's own multi-service pricing, such as a mobile plan plus nbn on one account; a new nbn and a new mobile ordered through ShopBack each have their own category amount shown on this page, though several SIMs on a single order earn once. For a deeper look, see Save on Optus.

Optus prepaid starter kits are sold on optus.com.au and through Coles, Woolworths, JB Hi-Fi and Australia Post, and the supermarkets and JB Hi-Fi periodically run catalogue weeks that discount a kit. Optus prepaid Cashback is for a kit bought on optus.com.au after you go through the ShopBack Optus page, matching a price point listed on this page. The ShopBack listings for Coles, Woolworths and JB Hi-Fi show whether they cover SIMs and mobile services. Compare the catalogue discount with the fixed Optus amount on this page before choosing.

The headline Optus windows are End of Financial Year (late June into July), Black Friday and Cyber Monday (late November) and Boxing Day, with Click Frenzy in May and November carrying smaller plan-level offers. What drops is usually the first 12 months of a plan rather than the headline price: a bigger data bucket at a lower monthly price for new services, plus waived nbn setup fees or added data, and on handsets a credit against a 24 or 36 month device repayment. Check optus.com.au in November for Optus's Black Friday pricing. During these sales, the sale price is what you pay at checkout. Going through ShopBack before you pay is an essential step, and part of what you spend comes back as Cashback. Check the rate shown on ShopBack's Optus page before you buy.

Check the ShopBack gift card hub at shopback.com.au/gift-cards for any discounted Optus gift card or ShopBack swap card. The main path on Optus is Cashback: go through ShopBack before you pay, and the fixed Cashback amount for your category shown on the ShopBack Optus page comes back once the plan confirms.

An Optus upsize shows as an Upsized label beside the affected category on the ShopBack Optus page and in the app, with the end date and time printed under it. ShopBack also surfaces live upsizes in the app's deals feed and in its email and push alerts if you have followed the Optus store, and the browser extension shows the current amount when you land on optus.com.au. Order during the window and the upsized amount is applied automatically; the tracking and 90-day confirmation rules are unchanged.

No single retailer is always cheapest for an iPhone in Australia, because the lowest total cost depends on whether you pay outright or on a plan and on which sale window you buy in. If you pay outright, compare Apple, JB Hi-Fi, Officeworks and Amazon AU, where sale events and price matching can undercut Apple's own price. If you want no upfront cost, a telco like Optus can work out cheaper overall once you count plan inclusions you would pay for anyway, but only if you stay for the full device term. Compare the full cost over the term in our Apple AU vs JB Hi-Fi vs Officeworks vs Optus vs Amazon iPhone 18 total cost comparison, then check the Cashback rate on the ShopBack Optus page and activate it before you sign up.

The cheapest way to buy an iPhone in Australia is usually to pay outright during a major sale window and pair it with a SIM-only plan, because you avoid paying for extras bundled into a device repayment. That suits shoppers with cash on hand who want to switch plans freely. If you would rather spread the cost, an Optus phone-on-plan can come close when you keep a plan you would have bought anyway, since the total over the term matters more than the monthly figure. Either way, add up handset plus plan over 24 or 36 months before deciding. See the full breakdown in our Apple AU vs JB Hi-Fi vs Officeworks vs Optus vs Amazon iPhone 18 total cost comparison, then check the Cashback rate on the ShopBack Optus page and go through ShopBack before you sign up.

Neither is always better value, because Optus and Telstra both sell plans on the same nbn network, so the fastest speed you can get is set by your address and connection type rather than by the provider. For the speed tier you want, compare three things: the monthly price once any introductory period ends, the typical busy period speed each provider publishes for that plan (Optus lists typical busy period speeds measured between 7pm and 11pm), and the commitment attached to an included modem (Optus provides its modem when you stay connected for 24 months on nbn plans, and also lets you bring your own compatible modem). If you also want a mobile plan or streaming bundled on one bill, the combined total can decide it. Whichever you choose, go through ShopBack before you sign up and check the live rate on this page.

Yes. Going through ShopBack is an essential step before you check out at Optus, and part of what you spend comes back as Cashback. Open this page, click through to optus.com.au, and complete the sign-up online. The current Cashback is shown on the Optus page on ShopBack before you sign up.

ShopBack's guides on Optus cover finding an inexpensive mobile plan, comparing wireless home broadband with fixed lines and comparing travel data SIM providers: What is the cheapest phone plan in Australia right now (2026)?, Is 5G Home Internet Cheaper Than NBN in Australia in 2026? and Which eSIM Provider Is the Cheapest in Australia in 2026?.
