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 replaces the old Emergency Alert system (2009), which relied on SMS and automated landline calls.

Managed by the National Emergency Management Agency (NEMA), AusAlert launches in October 2026 ahead of the 2026-27 bushfire season. A national test is scheduled for 27 July 2026.

The system was recommended by the 2020 Royal Commission into National Natural Disaster Arrangements (Recommendation 13.1), which found the existing Emergency Alert technology was "outdated" and unable to reach everyone facing an imminent threat.

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
• Works during network congestion (uses a separate signalling channel)
• Precision targeting down to 160 metres (a single building or street)
• Critical alerts override silent mode and Do Not Disturb
• Cannot be blocked or filtered like a regular phone number

Each device checks its own GPS location against the alert's target area. If you're not in the zone, the message is silently discarded. No location data is sent to the network.

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

• Capacity of only ~50,000 messages per hour (during the Brisbane floods, alerts took 10+ hours or failed entirely)
• Alerts came from +61444444444, which people blocked as spam
• Failed when: phone off, inbox full, wrong carrier location data, power outage with cordless phone
• Cross-border issues: residents near state borders received 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 33 government feeds from all 8 Australian states into one unified REST API with GeoJSON, CSV, and CAP-AU output formats. AusAlert handles the last-mile push to phones. EmergencyAPI handles structured data access for developers, researchers, and organisations.
