Apple began rolling out iOS 27 in the local market in Australia this week. The new build is live for eligible iPhone models. To set it up, go to Settings. Then open General. Then tap Software Update. The phone will check for the update and display it if the device is supported. Not every older device will get iOS 27. The launch date for iOS 27 is September 14, 2026. So the rollout is live now. Some iPhone users will spot the update right away. Others are not eligible. The result is based on the handset.
