The best Optus mobile plans in 2026

Optus Promo Plan | 360GB Data | AU$69p/m (for 12 months, then AU$79 p/m)

I've selected the Optus Promo plan as, on paper, it offers the best overall value right now. For AU$69p/m for the first 12 months, you get 360GB of data each month, AU$10 of credit to put towards subscriptions via Optus' SubHub service and unlimited international calls and texts.

Total minimum cost: AU$69 | First year cost: AU$828 | Ongoing yearly cost: AU$948

iPhone 17 (256GB) | 50GB Data | 24 Months | AU$113.29 p/m

As our iPhone 17 review states, this is the best-value iPhone ever, serving up Pro-level features, plenty of power and a gorgeous display. I've singled out a 24-month plan and have paired it with the Small 50GB plan. If you need more data, the Promo plan is available.

Total cost over 24 months is AU$2,718.96

iPhone Air (256GB) | 50GB Data | 24 Months | AU$109.09 p/m

The iPhone Air has perhaps not been quite the success Apple was expecting, but there's no denying it's a gorgeous device that has a lot going for it. It might only have a single camera, but it boasts the same processor as the 17 Pro, making for a phone that's a breeze to use. Right now, Optus has slashed AU$500.40 from the RRP of the iPhone Air on all plans.

Total cost over 24 months is AU$2,618.16

iPhone 17e (256GB) | 50GB Data | 24 Months | AU$96.61 p/m

The iPhone 17e is another great-value model from Apple, benefitting from the latest A19 processor, which gives it improved camera capabilities over the 16e. It also gets MagSafe, which is a very welcome addition. If you want an iPhone but don't want to break the bank, there's no better choice.

Total cost over 24 months is AU$2,318.64

Samsung Galaxy S26 Ultra (256GB) | 50GB | 24 months | AU$117.43p/m

The Galaxy S26 Ultra is easily the best best Android phone available right now, with a new Privacy screen feature and Super Steady video being two feature highlights. You can save AU$700 off RRP before April 8, and you can save AU$748 off a Galaxy Watch 8 when paired with a 24- or 36-month Watch Plan.

Total cost over 24 months is AU$2,818.32

Google Pixel 10 Pro (256GB) | 50GB | 24 months | AU$132.04p/m + free Pixel 9a

I'll admit I was quite shocked by the monthly price for this Google Pixel 10 Pro, as it's higher than the Samsung offer above (that will likely change when the AU$700 saving on the S26 Ultra comes to an end). However, with this deal you do get a free Pixel 9a, which could be handy if you have a second person in your family, or a friend, that needs a capable, mid-range phone.

Total cost over 24 months is AU$3,168.96

iPhone 17e (256GB) | 50GB Data | 24 Months | AU$96.61 p/m

The cheapest route to an iPhone with Optus is once again the iPhone 17e. I would've expected the 16e to have become cheaper given it's now been replaced, but it's actually the exact same price. Given the 17e is the superior device, I have to mention it here.

Total cost over 24 months is AU$2,318.64

Google Pixel 10a (128GB) | 50GB | 24 months | AU$90.37p/m

The Pixel 10a is the latest cost-friendly phone from Google. Admittedly it doesn't differ too much from the Pixel 9a it replaces, but that means it still gives you excellent photography skills and the purest form of Android.

Total cost over 24 months is AU$2,168.88

iPhone 17 Pro (256GB) | 50GB Data | 24 Months | AU$138.28p/m

If you've got the cash to splash and you want the best iPhone of the moment, look no further than the 17 Pro. Ushering in an all-new design, powerful cameras and AI smarts, it's all the phone you could ever need. Note that we've selected the base 256GB storage model and set it to a 24-month contract, your monthly price will change if you change these variables.

Total cost over 24 months is AU$3,318.72

Samsung Galaxy S26 Ultra (256GB) | 50GB | 24 months | AU$117.43p/m

It's the phone of the moment but also one that doesn't come cheap. Yet, if you do want to get the Galaxy S26 Ultra you can currently save AU$700 on RRP if you sign up before April 8.

Total cost over 24 months is AU$2,818.32

Samsung Galaxy Z Flip 7 (256GB) | 50GB Data | 24 Months | AU$129.94

If you want to go down the flip phone route, the Galaxy Z Flip 7 is an obvious choice. I have seen this phone and plan combo cost much less in the past, so I would recommend looking into other providers or holding out for sales if you know it's the phone for you.

Total cost over 24 months: AU$3,118.56
