What AusAlert Is
AusAlert is a new national emergency warning system delivered by the National Emergency Management Agency. It sends urgent messages to compatible mobile phones and other mobile devices inside a specified area, using cell-broadcast technology that is already used for public warning in more than 30 countries including the United States, United Kingdom, Canada, New Zealand, Japan and across the European Union.
It allows state and territory emergency services organisations, and some Australian Government agencies, to issue targeted warnings. It will eventually replace Emergency Alert, Australia’s existing SMS-based national alerting system.
| An AusAlert message tells you | Used for |
|---|---|
| What the emergency is | Natural hazards — bushfires, floods, cyclones, earthquakes, tsunamis |
| Where it is happening | Security threats — serious public safety incidents or terrorism |
| How serious it is | Biosecurity incidents — animal or plant disease, biohazard outbreaks |
| What you should do | Health emergencies — pandemics and other major public health events |
| Who sent it and where to find more | Messages are in English, with help guides available in other languages |
NEMA has also said that in future AusAlert will send automated voice messages to landline phones in a targeted area — which matters for premises where a fixed line is still the primary contact point.
Why Cell Broadcast Beats an SMS Blast
The distinction between cell broadcast and SMS sounds technical and is actually the whole point.
An SMS-based alert system has to know who to send to. It builds a list of numbers associated with an area and then sends individual messages to each one, through the same infrastructure that carries ordinary texts. In a real emergency, when everybody in the affected area is calling family and posting online, that infrastructure is exactly what is congested — so the messages queue, and some arrive after the danger has passed.
Cell broadcast works the other way round. The message is transmitted from the tower to every compatible device in range simultaneously, like a radio station rather than a mailing list.
Precisely targeted
Alerts go only to devices in the specified area, which can cross state and territory borders and can be narrowed to within about 160 metres — a single building. Outside the area, you get nothing.
Simultaneous
Everyone in the area receives it at the same moment. Millions of devices, effectively instantly, with no queue to work through.
Works when networks are busy
Because it is not an SMS, it is not competing with everyone else’s texts and calls. Devices do not even need an active SIM to receive one.
Private by design
AusAlert does not collect or store your phone number or your location, and only authorised emergency services and government agencies can send. That also makes it hard to imitate.
Impossible to ignore
For the most serious emergencies it plays a loud warning tone and vibrates — even if the phone is on silent or do not disturb.
Follows people in
While an alert is active, anyone entering the area receives it. You are only alerted again if the message is updated with new information.
A quiet anti-scam benefit
Because AusAlert never collects your number and only authorised agencies can broadcast, a criminal cannot send you a fake AusAlert. That is a meaningful improvement in an environment where SMS impersonation of government agencies has become routine — and it is worth telling your staff, because “the emergency alert on your phone is real; the text message claiming to be one is not” is a useful rule.
What the 27 July National Test Showed
At around 2:00pm AEST on Monday 27 July 2026, a test Critical Alert was sent to every compatible mobile device in Australia. Devices vibrated and played a siren-like sound for about ten seconds, and displayed a message that clearly identified itself as a test.

The precision alerts can be targeted to
NEMA was explicit that variation was expected and is not a failure. People with older devices, or alternative operating systems such as GrapheneOS or LineageOS, sometimes saw headings like “Presidential Alert” or “Extreme Threat Alert” instead of the Australian branding, because those devices do not follow the Australian standard. Others received nothing — an unsupported or un-updated device, no signal at the time, a tower down for maintenance, or a phone that was off or in aeroplane mode.
The one action NEMA asks of everyone
Keep device software up to date, and restart after updating. That is genuinely the main determinant of whether a phone can receive an AusAlert. For a business, that is a five-minute item to add to your device policy and your onboarding checklist — and it is worth doing before October rather than discovering the gap during an actual event.
What Happens Between Now and October
| When | What |
|---|---|
| June 2026 | Community tests at specific locations and times, building towards the national test. |
| 27 July 2026 | National test at around 2pm AEST. About 94% of mobile towers broadcast successfully. |
| August – September 2026 | Analysis and refinement. A sensible window for businesses to update device policies and rehearse their own emergency communications. |
| 1 October 2026 | AusAlert launches and becomes available to emergency services organisations and authorised agencies. |
| Beyond | Progressive replacement of the SMS-based Emergency Alert system, and the addition of automated voice messages to landline phones. |
The Gap AusAlert Deliberately Leaves
AusAlert is a public warning system. It exists to tell people in a defined area that something dangerous is happening and what to do about it. It is not, and was never intended to be, a business communications tool.
Here is the practical distinction, using a flood as the example.
| AusAlert does this | You still have to do this |
|---|---|
| Tells everyone in the affected area to evacuate now. | Tell your customers you are closed, and for how long. |
| Reaches your staff, wherever they physically are. | Account for your staff and know who is safe and who is not. |
| Describes the hazard and the required action. | Redirect your phones so calls are answered somewhere else. |
| Provides an official, trustworthy source. | Reassure clients with obligations or vulnerabilities that depend on you. |
| Covers a geographic area. | Reach customers, suppliers and staff who are outside that area but affected by it. |
| Warns once, and updates if things change. | Handle the flood of inbound calls from people asking whether you are open. |
That right-hand column is the communications half of a business continuity plan, and most Australian businesses have written the left-hand half — evacuation, muster points, first aid — while leaving the right-hand half entirely to improvisation on the day.
The First Three Hours of a Disruption
Whether it is a flood, a fire, a hazardous materials incident or a building evacuation, the communications sequence is remarkably consistent. Knowing it in advance is most of the work.
| Time | What needs to happen | What makes it possible |
|---|---|---|
| 0–15 min | Account for people. Who is on site, who is out on the road, who is safe. | A staff SMS broadcast with a reply request, sent from one place to everyone, from a phone rather than a desk. |
| 15–30 min | Change what callers hear. An honest recorded message beats ringing out or a voicemail nobody checks. | Editing your greeting and IVR from a mobile app in under two minutes. |
| 30–60 min | Move the calls. Route to whoever is safe and reachable — another site, home, mobiles, an AI agent. | Call flows that are configuration rather than a service call to a technician who cannot get to the building either. |
| 1–2 hrs | Tell customers proactively before they ring you. SMS to affected clients, a note on the site, social posts. | Outbound SMS from your business number, with two-way replies so people can respond. |
| 2–3 hrs | Absorb the inbound wave. Everybody rings at once, and most ask the same three questions. | An AI agent handling repeated questions, plus overflow and callback queues so nobody is abandoned. |
| Ongoing | Update as facts change, and be clear when you do not know yet. | The ability to re-record a message from anywhere, as many times as needed. |
Notice what every row has in common. None of it requires physical access to your premises, and none of it should require a technician. If any step in your plan depends on somebody being at the office or on a phone company processing a change request, that step will fail on exactly the day it matters.
Building the Communications Half of Your Plan
This is a one-page document, not a project. Six decisions, made once, written down, and known by more than one person.
1. Who decides
Named person and named deputy, with authority to change messaging without seeking approval. In an emergency, an approval chain is a delay mechanism.
2. Pre-written messages
Draft the greeting, the staff SMS and the customer SMS now, with blanks for detail. Nobody writes well under pressure.
3. Where calls go
A defined fallback: another site, home workers, mobiles, or an AI agent taking messages. Decided in advance, not invented on the day.
4. Contact lists that exist offline
Staff, key customers, suppliers, insurer, landlord. Accessible without the office network and without the building.
5. More than one admin
At least two people who can log in and change call flows. Single-person access is the most common continuity failure there is.
6. A test date
Twice a year, redirect the phones for ten minutes and put up the emergency greeting. Untested plans are aspirations.
Making Sure You Can Still Be Reached
An emergency communications plan assumes you have working communications. Worth checking that assumption, because most disruptions take out the power, the internet, or both.
| Risk | Mitigation |
|---|---|
| Power failure at your premises | A UPS on the router and network gear buys you the window to redirect calls. Cheap, quick, and the highest-value continuity purchase most small businesses can make. |
| Internet outage | A cloud system fails over to mobile apps and mobile data automatically. This is the structural advantage over an on-premise PBX, which is a box in a cupboard you may not be able to reach. |
| Mobile network congestion | Assume voice will be difficult in the affected area. SMS and data usually survive longer, which is why pre-planned messaging beats a plan built on ringing everyone. |
| Single carrier dependency | If everything runs over one network, one carrier incident takes out your whole plan — see why one network is a single point of failure. |
| Nobody can reach the building | Every element of your plan must be operable from a mobile phone, from anywhere. If it is not, it is not a plan. |
| Emergency calls from a cloud phone | Your registered service address is what tells the emergency call service where you are. Keep it accurate — see Triple Zero from a cloud phone. |
Run Your Own Test
The government tested its system in front of the entire country. The obvious follow-up question for any business is when you last tested yours.
A useful drill takes fifteen minutes and needs no notice to customers if you do it outside business hours.
| Step | Do | Look for |
|---|---|---|
| 1 | Ask someone other than the usual administrator to change the main greeting to an emergency message. | Can they log in? Do they know how? How long did it take? |
| 2 | Redirect the main number to a mobile and ring it from an outside line. | Does it arrive, and does the person answering know it is a redirected business call? |
| 3 | Send a test SMS broadcast to all staff asking for a reply. | Is the list current? How many replied within ten minutes? |
| 4 | Do all of the above from a phone, standing outside the building. | Any step that needed a desktop, the office network or a support ticket is a defect. |
| 5 | Put everything back and write down what took longest. | That is your improvement list, and it is usually short. |
Sectors With Extra Obligations
For some organisations, being reachable during an emergency is not a customer service matter but a duty.
Health and aged care
People with clinical needs must be able to reach you or be told where to go instead. A ringing phone that nobody answers is a clinical risk, not an inconvenience.
Disability services
Participants may be in supported accommodation in the affected area. Contactability is part of your duty of care and your continuity obligations.
Schools and childcare
Every parent rings simultaneously. Without overflow and a clear recorded message, the line is engaged for the ones who most need it.
Essential trades and utilities
Demand spikes precisely when the emergency hits. Capacity to answer is the difference between helping and being unreachable.
AusAlert going live on 1 October is genuinely good news — Australia is getting a faster, more accurate, harder-to-fake public warning system, and the July test showed it working across the great majority of the network. Use the moment for what it is worth: a free, well-publicised prompt to check whether the communications half of your own plan would survive contact with a real Tuesday afternoon.
