Apple began rolling out iOS 27 across the country in Australia in the current week. The update is available for eligible iPhone models. To set it up, launch Settings. Then select General. Then tap Software Update. The phone will check for the update and show it if the device is eligible. Not every older device will see iOS 27. The arrival date for iOS 27 is September 14, 2026. So the release is live now. Some iPhone users will spot the update straight away. Others will not. The result hinges on the handset.
