What is AusAlert?

AusAlert is Australia's new national emergency warning system. It uses cell broadcast technology to send urgent alerts directly to every compatible mobile phone in a targeted area. It will replace the existing Emergency Alert system (2009), which relies on SMS and automated landline calls and remains in operation with no announced retirement date.

Managed by the National Emergency Management Agency (NEMA), AusAlert launches on 1 October 2026 ahead of the 2026-27 high risk weather season, with alert sending subject to individual state and territory agreements. A national test is scheduled for Monday 27 July 2026.

The system was created in response to the 2020 Royal Commission into National Natural Disaster Arrangements (Recommendation 13.1), which called for a modern national warning capability to replace the ageing Emergency Alert technology.

Unlike SMS (which sends one message per phone number), cell broadcast sends a single message from a mobile tower to every device in range simultaneously. This means:

• No phone numbers or SIM cards required
• Carrier-agnostic: works across all providers on active 4G and 5G networks
• Precision targeting down to 160 metres (a single building or street), including areas that cross state borders
• Critical Alerts override silent mode and Do Not Disturb and cannot be opted out; lower-level Priority Alerts can be turned off in device settings
• Re-broadcasts during an alert period, so devices entering the area later still receive it

Alerts are broadcast from mobile towers covering the target area. The system does not collect or store phone numbers or locations.

The current Emergency Alert system (launched 2009) sends location-based SMS messages and automated landline calls. It has well-documented limitations:

• SMS is sent one message per number, so large alerts queue; during past flood emergencies, throughput limits meant warnings took hours to deliver
• Alerts come from +61 444 444 444, a number some people block as spam
• Fails when: phone off, inbox full, wrong carrier location data, power outage with cordless phone
• Cross-border issues: residents near state borders can receive irrelevant alerts

For a detailed comparison, see AusAlert vs Emergency Alert.

AusAlert is a push notification system. It sends alerts to phones. It does not provide:

• A developer API or data feed
• Historical incident data or archives
• Query-based access (filter by location, type, severity)
• Cross-agency data aggregation
• Structured data for building applications

This is a significant gap compared to international systems. The US Federal Emergency Management Agency (FEMA) provides IPAWS-OPEN, a free developer API with test environments and archived alert datasets. Australia has no equivalent.

EmergencyAPI fills this gap. It aggregates 34 government feeds from all 8 Australian states and territories into one unified REST API with GeoJSON, CSV, and a standards-validated CAP Atom feed. AusAlert handles the last-mile push to phones. EmergencyAPI handles structured data access for developers, researchers, and organisations.
