Two O’Clock on a Monday
Monday 27 July 2026, around 2:00pm AEST. In offices, utes, classrooms and waiting rooms across the country, phones went off simultaneously — a siren-like tone and ten seconds of vibration, overriding silent mode and do not disturb, with a message on screen that said plainly that it was a test.
That was AusAlert, and it goes live on 1 October 2026.
It is a genuine step forward for public safety in Australia. It is also, if you run a business, an unusually well-publicised prompt to ask a question almost nobody asks until the day it matters: if something went wrong here tomorrow, could we actually tell anyone?
Not evacuate — most businesses have that written down. We mean the other half. Change what callers hear. Move the calls to somebody who is safe. Message every staff member and know who replied. Tell three hundred customers before they ring you. From a mobile phone, standing in a car park, with no access to the building and no help from a technician.
What AusAlert Actually Is
AusAlert is Australia’s new national emergency warning system, delivered by the National Emergency Management Agency. It sends urgent messages to compatible mobile phones and other mobile devices in a specified area, and it will eventually replace Emergency Alert, the SMS-based system Australia has used until now.
State and territory emergency services organisations and some Australian Government agencies can issue the alerts. Every message tells you what the emergency is, where it is happening, how serious it is, what you should do, who sent it, and where to find more information.
| Used for | Examples |
|---|---|
| Natural hazards | Bushfires, floods, cyclones, earthquakes, tsunamis |
| Security threats | Serious public safety incidents, terrorism |
| Biosecurity incidents | Animal or plant disease, biohazard outbreaks |
| Health emergencies | Pandemics and other major public health events |
NEMA has also indicated that AusAlert will in future send automated voice messages to landline phones inside a targeted area — relevant for premises where a fixed line remains the main point of contact.
Cell Broadcast, and Why It Is Better
The technology change is the reason this is an upgrade rather than a rebrand.
An SMS alert system must know who to send to. It assembles a list of numbers in an area and sends individual messages over the same infrastructure carrying everybody’s ordinary texts — which, during an emergency, is exactly the infrastructure that is jammed. Messages queue. Some arrive after they were useful.
Cell broadcast transmits from the tower to every compatible device in range at once. It behaves like a radio broadcast rather than a mailing list, and that single architectural difference produces every advantage below.
160 m
Targeting precision — down to a single building, and able to cross state borders
All at once
Millions of devices reached simultaneously, with no queue to work through
No SIM
Devices do not need an active SIM to receive an alert
Zero
Phone numbers or locations collected or stored by the system
Two consequences are worth pulling out. First, alerts still get through when the mobile network is congested, because they are not competing with everyone’s calls and texts. Second — and this deserves a line in your next staff security briefing — because only authorised agencies can broadcast and the system never collects your number, a criminal cannot send you a fake AusAlert. The alert on your phone is real; the text message claiming to be one and asking you to tap a link is not.
What the Test Told Us
The national test sent a single Critical Alert to every compatible device in Australia. About 94% of all mobile towers broadcast it successfully.
NEMA was upfront that inconsistent results were expected and were part of the point. Some people with older handsets or alternative operating systems such as GrapheneOS or LineageOS saw headings like “Presidential Alert” or “Extreme Threat Alert”, because those devices do not follow the Australian standard even though the message content was identical. Others received nothing at all — an unsupported or un-updated device, no signal at that moment, a tower down for maintenance, or a phone switched off or in aeroplane mode.
The one thing NEMA asks everybody to do
Keep device software current, and restart after updating. That is the main determinant of whether a phone can receive an AusAlert at all. For a business it is a five-minute addition to your device policy and your new-starter checklist — worth doing in August rather than discovering the gap during a real event in summer.
What It Will Never Do for You
AusAlert is a public warning system. It is not, and was never meant to be, a business communications tool. The distinction is easiest to see side by side.
| AusAlert handles | Still entirely yours |
|---|---|
| Telling everyone in the area to evacuate now. | Telling your customers you are closed, and for roughly how long. |
| Reaching your staff wherever they physically are. | Knowing which of your staff are safe and accounted for. |
| Describing the hazard and the required action. | Getting your calls answered by somebody who is not in the affected area. |
| Being an official, trustworthy source. | Reassuring the clients whose own obligations depend on reaching you. |
| Covering a geographic area. | Reaching people outside that area who are affected because you are in it. |
| Warning once, updating if things change. | Absorbing three hundred calls asking the same three questions. |
Every Australian business has an evacuation plan, because that column is regulated and inspected. Very few have written the right-hand column down, and it is the one customers actually experience.
The First Three Hours
Fire, flood, hazardous materials, a police cordon, a burst main, a building evacuation — the cause varies and the communications sequence barely does.
| Window | What has to happen | What makes it possible |
|---|---|---|
| First 15 minutes | Account for people. Who was on site, who is on the road, who is safe. | One SMS broadcast to all staff asking for a reply, sent from a phone. |
| 15–30 minutes | Change what callers hear. An honest recorded message beats ringing out. | Re-recording the greeting and adjusting the IVR from a mobile app in under two minutes. |
| 30–60 minutes | Move the calls somewhere they can be answered — another site, home, mobiles, an AI agent. | Call flows that are a setting you change, not a service request to somebody who also cannot reach the building. |
| 1–2 hours | Tell customers before they ring. SMS to affected clients, a website note, social posts. | Outbound SMS from your business number, two-way so people can reply and be answered. |
| 2–3 hours | Absorb the inbound wave without abandoning anyone. | An AI agent answering the repeated questions, plus overflow and callback queues. |
| Ongoing | Update as facts change; say plainly when you do not know yet. | Being able to re-record from anywhere, as often as needed, without asking permission. |
The common thread
Not one row requires access to your premises, and not one 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 within the hour, that step will fail on precisely the day you need it. That is the practical case for a cloud system over a box in a cupboard, and it is not a marketing argument — it is what happened to businesses in every major Australian disruption of the last five years.
The One-Page Plan
This is not a project. It is six decisions, made once, written on a page that more than one person has seen.
Who decides
A named person and a named deputy with authority to change messaging immediately. An approval chain in an emergency is just a delay with a job title.
Pre-written words
Greeting script, staff SMS and customer SMS drafted now with blanks for the detail. Nobody writes clearly under pressure.
Where calls go
A decided fallback — second site, home workers, mobiles, or an AI agent taking structured messages. Chosen in advance, not invented at 9am.
Lists that work offline
Staff, key customers, suppliers, insurer, landlord — reachable without the office network and without the building.
Two administrators, minimum
At least two people who can log in and change call flows. Single-person access is the most common continuity failure in existence.
A test in the calendar
Twice a year. An untested plan is a document, not a capability.
Checking the Assumptions Underneath
Every communications plan quietly assumes you still have communications. Most disruptions take out power, internet, or both.
| Assumption | What to do about it |
|---|---|
| “We’ll have power” | A small UPS on the router and network gear gives you the window to redirect calls before everything goes dark. For most small businesses it is the single best-value continuity purchase available. |
| “We’ll have internet” | A cloud phone system falls back to mobile apps over mobile data automatically. An on-premise PBX is a box in a cupboard inside the building you have just evacuated. |
| “We’ll just ring everyone” | Voice is the first thing to congest in an affected area. SMS and data typically survive longer, which is why the plan should lead with messaging. |
| “Our carrier will be fine” | If everything rides on one network, one carrier incident takes out the whole plan — see why one network is a single point of failure. |
| “Someone can get to the office” | Assume nobody can. Every element must be operable from a mobile, from anywhere, by two different people. |
| “000 knows where we are” | Your registered service address is what tells the emergency call service your location. Keep it current — see Triple Zero from a cloud phone. |
A Fifteen-Minute Drill
The government tested its system in front of 27 million people. Here is the small-business version, and it can be done after hours with nobody noticing.
| Step | Do this | The thing you are actually testing |
|---|---|---|
| 1 | Ask someone who is not the usual administrator to change the main greeting to an emergency message. | Whether knowledge and access exist in more than one head. |
| 2 | Redirect the main number to a mobile and ring it from an outside line. | Whether the redirect works and whether the answerer knows it is a business call. |
| 3 | Send an SMS broadcast to all staff asking for a one-word reply. | Whether the list is current, and how long a response actually takes. |
| 4 | Do every step above on a phone, standing outside the building. | Whether the plan survives losing the premises — which is the whole scenario. |
| 5 | Restore everything and write down what took longest. | Your improvement list. It is usually two items and both are fixable in an hour. |
Most businesses that run this discover the same two defects: only one person actually knows how to change the phone system, and the staff mobile list is eighteen months out of date. Both are trivial to fix once you know, and impossible to fix at 7am during a flood.
When Being Reachable Is a Duty
For some organisations this stops being customer service and becomes obligation.
| Sector | Why the phone matters more |
|---|---|
| Health and aged care | People with clinical needs must reach you or be told where to go instead. An unanswered line is a clinical risk, not an inconvenience. |
| Disability services | Participants may be in supported accommodation inside the affected area. Contactability is part of duty of care and of your continuity obligations. |
| Schools and childcare | Every parent rings within the same four minutes. Without overflow and a clear recorded message, the line is engaged for the ones who most need it. |
| Trades and essential services | Demand spikes exactly when the emergency does. Capacity to answer is the difference between being useful and being unreachable. |
AusAlert going live on 1 October is good news, and the July test showed it working across the overwhelming majority of the network. Take it for what it is worth to you: a free, loudly publicised reminder to spend fifteen minutes finding out whether your own emergency communications would survive contact with a real Tuesday afternoon — because the government just did exactly that, in public, and found a few things to fix.
Frequently Asked Questions
What is AusAlert and when does it launch?
AusAlert is Australia's new national emergency warning system, delivered by the National Emergency Management Agency, launching on 1 October 2026. It sends urgent messages to compatible mobile phones and other devices within a specified area using cell-broadcast technology, which is already used for public warning in more than 30 countries including the United States, United Kingdom, Canada, New Zealand, Japan and the European Union. State and territory emergency services organisations and some Australian Government agencies will be able to issue targeted warnings for natural hazards such as bushfires, floods, cyclones and tsunamis, security threats including terrorism and serious public safety incidents, biosecurity incidents, and health emergencies. Every message states what the emergency is, where it is happening, how serious it is, what you should do, who sent it and where to get more information. It will progressively replace Emergency Alert, the SMS-based system Australia has used until now, and NEMA has said automated voice messages to landlines will be added in future.
What happened during the 27 July 2026 national test?
At around 2:00pm AEST on Monday 27 July 2026, a single test Critical Alert was broadcast to every compatible mobile device in Australia, including most phones and some smart watches and tablets. Devices vibrated and played a siren-like sound for approximately ten seconds, overriding silent and do-not-disturb settings, and displayed a message clearly identifying itself as a test. About 94 per cent of all mobile towers broadcast the alert successfully. NEMA stressed that variation was expected rather than a failure - people with older handsets or alternative operating systems such as GrapheneOS or LineageOS sometimes saw headings like Presidential Alert or Extreme Threat Alert because those devices do not follow the Australian standard, while others received nothing because their device was unsupported or not updated, had no signal, was switched off or in aeroplane mode, or their nearest tower was offline for maintenance. Learning exactly how devices behave in the wild was one of the main purposes of testing before launch.
Why is cell broadcast better than emergency SMS?
Because it does not depend on knowing who to send to, and it does not compete for the same capacity. An SMS alert system assembles a list of numbers in an area and sends individual messages through the infrastructure that carries everybody's ordinary texts - which in an emergency is precisely what is congested, so messages queue and some arrive too late to be useful. Cell broadcast transmits from the tower to every compatible device in range simultaneously, more like a radio station than a mailing list. That produces several advantages at once: alerts reach everyone in the target area at the same instant, targeting can be as precise as about 160 metres and can cross state and territory borders, delivery still works when the network is busy, devices do not need an active SIM, and the system collects no phone numbers or location data. It also plays a loud tone and vibrates even when a phone is set to silent.
Will AusAlert tell my customers that my business is closed?
No, and this is the most important thing for a business owner to take from the launch. AusAlert is a public warning system - it tells people in an affected area what the hazard is and what action to take, and it will reach your staff wherever they are, which is genuinely valuable. What it does not do is tell your customers you are shut, redirect your phone lines to somebody who is safe, account for which of your team are okay, reassure clients whose own obligations depend on reaching you, contact people outside the alert area who are affected because you are inside it, or absorb the flood of inbound calls asking whether you are open. That entire list is the communications half of a business continuity plan. Most Australian businesses have written the evacuation half because it is regulated and inspected, and left the half that customers actually experience to improvisation on the day.
What should we do before 1 October?
Three things, none of which takes long. First, push a device software update across the organisation and have people restart afterwards, because software currency is the main determinant of whether a phone can receive an alert at all - then add it to your device policy and new-starter checklist so it stays true. Second, write the communications half of your continuity plan on one page: who has authority to change messaging, pre-drafted greeting and SMS wording with blanks for the specifics, a decided fallback for where calls go, contact lists that exist outside the office network, and at least two people who can administer the phone system. Third, run a fifteen-minute drill. Have someone other than the usual administrator change the greeting, redirect the main number to a mobile, send a test SMS broadcast asking for replies, and do all of it standing outside the building on a phone. Anything that needed a desktop or a support ticket is a defect you just found for free.
Can scammers send fake AusAlert messages?
No. AusAlert does not collect or store your phone number or location, and only authorised emergency services organisations and Australian Government agencies can broadcast through the system. Because cell broadcast is a transmission from the network rather than a message addressed to your number, there is no path for an outsider to inject one. That is a real benefit at a time when SMS impersonation of government agencies has become routine, and it gives your team a clean rule to work with: an alert that appears on the phone with AusAlert branding and the distinctive tone is genuine, while a text message claiming to be an emergency alert and asking you to tap a link is not. It is worth putting that line into a staff briefing before October, because the launch of any prominent new government system reliably attracts a wave of scams pretending to be it.
What happens to our phones if the power or internet goes out?
Plan for both, since most disruptions take one or the other. A small uninterruptible power supply on the router and network equipment is inexpensive and buys the window you need to redirect calls before everything goes dark - for most small businesses it is the highest-value continuity spend available. For internet loss, a cloud phone system fails over automatically to mobile apps over mobile data, which is the structural advantage over an on-premise PBX sitting in a cupboard inside the building you have just evacuated. Expect voice calls to be difficult in the affected area because of congestion, while SMS and data usually hold up longer, which is why a good plan leads with messaging rather than with ringing everyone. Also check for single-carrier dependency, because one carrier incident can otherwise take out every part of your plan simultaneously. The governing test is simple: if a step requires physical access to your premises, it is not a plan.
