Samsung’s new Galaxy S26 lineup is now up for pre-order, and while the perks being offered by Telstra, Optus and Vodafone might seem tempting at first glance, they’re not the most cost-effective options in the long run.
Buying from a major telco often means paying the same price for the phone while getting locked into expensive mobile plans. The good news is you can save hundreds by skipping those long-term contracts and purchasing your phone outright.
To help you find the cheapest Samsung Galaxy S26, I’ve compared the total costs of the Galaxy S26, S26 Plus and S26 Ultra from each of the three main telcos over 24 months, factoring in the price of their cheapest eligible plan, device repayments and pre-order discounts. Then, I'll show you some cheaper alternatives.
Galaxy S26: Telstra pricing
Unlike many other S26 pre-order offers, Telstra isn’t offering a free storage upgrade. In its place, Telstra is offering discounted monthly rates over 24 months, adding up to AU$400 off for the Galaxy S26, AU$500 for the Galaxy S26 Plus and AU$700 off for the Galaxy S26 Ultra.
The prices listed don’t include trade-ins and show what you’ll pay over 24 months when the device is paired with Telstra’s Basic plan, which comes with 50GB of data each month.
Model (512GB) | RRP | Pre-order discount | Device p/m | Basic Plan (p/m) | Total cost (24 months) |
Galaxy S26 | AU$1,849 | -AU$400 | AU$60.37 | AU$70 | AU$3,128.88 |
Galaxy S26 Plus | AU$2,149 | -AU$500 | AU$68.70 | AU$70 | AU$3,328.80 |
Galaxy S26 Ultra | AU$2,499 | -AU$700 | AU$74.95 | AU$70 | AU$3,478.80 |
Galaxy S26: Optus pricing
Like Telstra, Optus is rolling out discounted monthly plans for pre-orders, with savings of AU$500 over 24 months on the Galaxy S26 and S26 Plus, and AU$700 on the Galaxy S26 Ultra.
Additionally, the telco is also offering a free storage upgrade valued at AU$300, edging out Telstra in the perks department. The pricing below does not include trade-ins and is based on Optus' entry-level $55 Small Choice Plus Plan, which offers 50GB of monthly data.
Model (512GB) | RRP | Pre-order discount | Device p/m | Small Choice Plus Plan (p/m) | Total cost (24 months) |
Galaxy S26 | AU$1,849 | -AU$500 | AU$56.19 | AU$55 | AU$2,860.56 |
Galaxy S26 Plus | AU$2,149 | -AU$500 | AU$68.67 | AU$55 | AU$2,968.08 |
Galaxy S26 Ultra | AU$2,499 | -AU$700 | AU$74.91 | AU$55 | AU$3,117.84 |
Galaxy S26: Vodafone pricing
Surprisingly, Vodafone isn’t giving a free storage upgrade to customers who pre-order a Galaxy S26. Instead, it’s offering reduced device repayments and lower monthly plan rates spread over 24 months. The savings work out to AU$400 off the S26, AU$500 off the S26 Plus, and AU$700 off the S26 Ultra.
The pricing below does not include trade-ins and is based on Vodafone's entry-level Small Plan, which includes 60GB of monthly data and is usually priced at AU$53 per month, but is discounted to AU$39 per month for the duration of your contract.
Model (512GB) | RRP | Pre-order discount | Device p/m | Small Plan (p/m) | Total cost (24 months) |
Galaxy S26 | AU$1,849 | -AU$400 | AU$60.37 | AU$39 | AU$2,384.88 |
Galaxy S26 Plus | AU$2,149 | -AU$500 | AU$68.70 | AU$39 | AU$2,584.80 |
Galaxy S26 Ultra | AU$2,499 | -AU$700 | AU$74.95 | AU$39 | AU$2,734.80 |
Galaxy S26: Cheaper alternatives
If you're able to purchase your Samsung Galaxy S26 outright, you'll get the biggest savings from Amazon, which has an incredible pre-order offer for Prime members. Like some of its rivals, Amazon is offering a free storage upgrade to the 512GB across all three models, but Prime members get an additional AU300 discount at checkout.
In other words, that's a massive AU$600 saving that doesn't require you to sign up for any long-term phone plans. That brings the Galaxy S26 (512GB) down to just AU$1,849 AU$1,249, the Galaxy S26 Plus (512GB) down to just AU$2,149 AU$1,549 and the Galaxy S26 Ultra (512GB) down to just AU$2,499 AU$1,899.
All you have to do is sign up for a 30-day free trial of Amazon Prime, with no obligation to continue beyond the first month.
Samsung’s online store has the next best outright deal: get a free upgrade to the 512GB storage option, valued at AU$300, on all three models, which means you’ll score the 512GB version of your chosen phone for the price of the 256GB model.
But that's not all — those in the market for a Galaxy S26 Ultra can combine our exclusive S26TECH code with the initial AU$300 discount to score an extra AU$150 off the 1TB model. That brings its price down to the 512GB model’s RRP, giving you double the storage at no additional cost.
It’s worth noting that when you buy from Samsung, you don’t have to pay the full amount upfront — you can choose to pay it off in monthly instalments over 24 months with Samsung’s interest-free finance option.
For the standard Galaxy S26 with 512GB of storage, that works out to AU$64.54 p/m without trade-in, or from as little as AU$28.50 p/m with up to AU$865 in trade-in value.
Not only is it much more affordable than being stuck in a long-term contract with one of Australia's big three telcos, but this option also gives you access to a range of cheap mobile plans that provide a decent amount of data while keeping your expenses down.
For instance, you could pair the payment plan above with our top cheap plan recommendation, TPG's 25GB Small Plan, which is priced at an incredibly affordable AU$12.50 p/m for the first 6 months, after which the price goes up to AU$25 p/m.
Assuming you've traded in a device for the full AU$865, the combined AU$28.50 p/m device cost and AU$12.50 p/m plan cost works out to just AU$41 p/m during that initial 6-month period. After that, the price will still only be AU$53.50 p/m.
And if you don't trade in a device, the combined price during the first 6 months works out to a very reasonable AU$77.04 p/m, rising to AU$89.54 p/m afterward.
Bottom line
If you’re looking to buy a Galaxy S26 outright, Amazon gives you the best upfront deal with a free automatic storage upgrade worth AU$300, plus an extra AU$300 off at checkout for Prime members.
If you'd rather pay for the device through a payment plan without committing to a 24-month contract, Samsung’s interest-free financing is a great choice. You still get a free storage upgrade, plus the option to trade in your old device for up to AU$865 in value.
Both options let you pick your own SIM-only plan without the hassle of lock-in contracts, giving you control over how much you want to spend each month. No matter which you choose, chances are you’ll save money in the long run compared to signing up via a telco.
