Apple began rolling out iOS 27 in the local market in Australia this week. This software is live for compatible iPhone models. To install it, launch Settings. Then tap General. Then choose Software Update. The phone will check for the update and list it if the device is eligible. Only some older models will see iOS 27. The release date for iOS 27 is September 14, 2026. So the rollout is live now. Some iPhone users will get the update straight away. Others won't. The result is based on the handset.
