Apple began rolling out iOS 27 across the country in Australia this week. The update is available for compatible iPhone models. To get the update, launch Settings. Then select General. Then choose Software Update. The phone will scan for the update and display it if the device is eligible. Not all older devices will receive iOS 27. The arrival date for iOS 27 is September 14, 2026. So the release is underway now. Certain iPhone users will spot the update right away. Others are not eligible. The result is based on the handset.
