Apple began rolling out iOS 27 in the local market in Australia in the current week. The new build is ready for compatible iPhone models. To install it, launch Settings. Then select General. Then tap Software Update. The phone will look for the update and display it if the device is compatible. Not all older devices will see iOS 27. The release date for iOS 27 is September 14, 2026. So the release is underway now. Certain iPhone users will get the update straight away. Others won't. The result depends on the handset.
