Best iPhone 15 Plus plans in Australia (September 2025)

The iPhone 17 and its many variants – including a rumoured iPhone 17 Air – are set to be announced soon, but for those seeking a cheaper upgrade, there are few better options than the iPhone 15 Plus.

It might not have the power for Apple Intelligence features like writing prompts and custom emojis. However, if you want an excellent smartphone with a big display and smooth performance, the iPhone 15 Plus is a great choice. Plus, as it approaches its second birthday, it's becoming more affordable when bought outright from retailers like The Good Guys and Amazon.

Unlike retailers, which stock popular phones for years, telcos often have limited stock of older devices, as is the case here. As of writing, Optus is the only member of the big three still carrying the iPhone 15 Plus. However, until September 9, it is cutting the prices of its small and medium plans by AU$15 per month for the first 12 months – giving you two very enticing options for the best iPhone 15 Plus plans.

iPhone 15 Plus: Key information

Similar to the iPhone 15, the iPhone 15 Plus has gotten a raft of upgrades this year: Dynamic Island, a USB-C charging port, a more powerful processor and a seriously beefed up main camera. We’d argue that these changes make this generation of Apple’s Plus phone much more appealing than the iPhone 14 Plus that came before it.

Dynamic Island was exclusive to last year’s Pro models, but now it’s available on both the iPhone 15 and iPhone 15 Plus. If you’re unfamiliar with Dynamic Island, it’s the pill-shaped cutout where the camera notch used to be at the top of the screen. It can expand to turn into a notification centre of sorts, allowing you to use Spotify, check your Uber, see incoming calls and much more.

We’re happy to report that while the 15 Plus has kept the straight sides that have been a mainstay for iPhones over the past few years, Apple has softened the edges to make them a little more rounded. We think that’s particularly good for an iPhone of this size, as its 6.7-inch screen should feel more comfortable in your hands for longer periods. And while we’re talking about design, RIP to the Lightning charging port. Apple has finally embraced USB-C.

iPhones have housed 12MP cameras for a long time, but this year, finally, Apple has given the iPhone 15 Plus a 48MP sensor – it’s about time. A bigger sensor should give you better shots in all environments, but you might notice the biggest difference when taking photos in low light. Apple is also promising improved portrait photography and better results when using 2x zoom.

You can get the iPhone 15 Plus in pastel shades of pink, yellow, green and blue, and there’s also a black colour option for those who want something more neutral. While the iPhone 15 Plus launched at prices starting at AU$1,649, the 128GB model can now regularly be had for less than AU$1,400.
