The Australian Telecommunications Alliance (ATA) (formerly Communications Alliance) has recently published updated versions of the Australian standards for telecoms mobile devices AS/CA S042.1:2025, AS/CA S042.4:2025 and AS/CA S042.5:2025.

Key changes

The main change to the standards is to include requirements for devices to support cell broadcast emergency alerts in Australia when the National Messaging System (NMS) is operational.

For more information on the new standards, please see the Australian Telecommunications Alliance (ATA) news.

The new versions of the standards were published on 30 June 2025. There is a 12-month transition period before suppliers must use the 2025 editions.

Until 30 June 2026, suppliers have the option of complying with the 2022 editions or the 2025 editions.

However, suppliers and manufacturers are encouraged to comply with the 2025 editions to ensure their devices will correctly support the Australian National Messaging System (NMS) when it becomes operational.

For more information on the National Messaging System, please see the Australian Government National Emergency Management Agency website.
