Australia's Emergency Alert System: How It Works

National Public Warning System

The Emergency Alert is Australia's national telephone-based warning system, used by emergency services to send urgent messages to landlines and mobile phones in defined geographic areas during life-threatening emergencies.

Activation Authorities

  • State/territory emergency management agencies
  • Australian Federal Police (AFP)
  • Bureau of Meteorology (BoM)

Three Alert Levels

LevelNameMeaningAction Required
1AdviceIncident has started; no immediate dangerStay informed, monitor conditions
2Watch and ActHeightened threat; conditions changingPrepare to act, protect yourself
3Emergency WarningImminent danger to life/propertyTake immediate action (evacuate, shelter)

Delivery Channels

  • Voice messages to landlines
  • Text messages to mobiles (based on billing address or last known location)
  • TV/radio interrupts (via Emergency Alert System)
  • Social media and emergency apps (e.g., Emergency+)

The system does not use sirens. Alerts are location-targeted, not broadcast nationally. Always follow instructions from official sources.
