If your portfolio crosses the Northern Territory and the eastern states, there’s a small assumption that quietly breaks: “we’ll just register all our AEDs on GoodSAM.” You can’t. The NT doesn’t use GoodSAM, and neither does Western Australia. The way an AED gets onto the emergency map genuinely differs depending on which state the device sits in, and the NT is the clearest example of why. Here’s the practical breakdown for someone managing devices across more than one jurisdiction.
Why the NT is different: St John is the ambulance service
In most states, the ambulance service is a government agency, and it bolts a voluntary AED registry onto its dispatch system. The NT works differently. St John Ambulance NT is the contracted ambulance provider for the entire Territory — it isn’t a charity sitting alongside the ambulance system, it is the ambulance system. St John NT runs the road ambulances and the Triple Zero communications centres in Darwin and Alice Springs.
That changes the registration pathway. In the NT, you register an AED through the St John NT First Responder app, not GoodSAM. When a member of the public uses the app to call 000, it sends GPS coordinates to the operator and gives the dispatcher visibility of registered public-access defibrillators nearby. Same goal as GoodSAM — get a bystander to a device fast — but a different platform, run by the same organisation that answers the emergency call.
Registration is voluntary and free. There’s no NT law requiring it. But it’s the step that makes your device findable when it counts, so it’s always worth doing.
Australia’s AED registration map isn’t one system — it’s several
Here’s the part that catches national operators out. There’s no single Australian AED registry. There are several, and they don’t talk to each other:
| Model | States | How registration works |
|---|---|---|
| St John contracted-provider app | NT, WA | St John runs the ambulance service and its own AED platform (First Responder app / State Defib Network) |
| GoodSAM (voluntary) | NSW, VIC, TAS | Government ambulance service with a voluntary GoodSAM registry, integrated with Triple Zero and a responder network |
| Mandatory state register | SA | SA Ambulance register — registration is legally required under the AED Act, integrated with 000 |
| Property-only / no government registry | QLD, ACT | QLD’s QAS registry records location only; the ACT has no government registry (St John national register fills the gap) |
A device in Darwin, a device in Sydney and a device in Adelaide all need to be on a map — but three different maps, reached three different ways. Assuming one platform covers the lot is the single most common mistake in a multi-state AED rollout.
The GoodSAM states: NSW, VIC and Tasmania
New South Wales, Victoria and Tasmania run government ambulance services that use GoodSAM for AED registration. The model is consistent across the three:
- Registration is voluntary and free, done online through each state’s GoodSAM portal.
- Registered devices are visible to Triple Zero call-takers, who can direct a caller to the nearest one.
- They’re also visible to GoodSAM Responders — opted-in trained volunteers who get real-time alerts, including AED locations, when there’s a cardiac arrest nearby.
- Tasmania goes a step further and publishes registered devices on the public LISTmap layer.
If you know the GoodSAM process from one of these states, the other two feel familiar. The portals differ but the model doesn’t.
The St John states: NT and WA
The NT and WA are the two jurisdictions where ambulance services are run by St John under contract rather than by a government agency — and both run their own AED platforms instead of GoodSAM.
- NT: the St John NT First Responder app, as above.
- WA: St John WA’s State Defib Network, fed through the St John WA First Responder app and the Community First Responder registration process. When a 000 call comes in, St John WA’s operations centre can direct the caller to the nearest registered device using that network.
For a portfolio that spans the NT and WA, the good news is the model is similar across both — St John, custom app, voluntary registration. The catch is they’re separate networks. A WA device goes on the State Defib Network; an NT device goes on the First Responder app. Don’t assume registering in one covers the other.
The two that fit neither model
Worth knowing for completeness, because a national portfolio will hit them:
- South Australia is the only state where registration is mandatory. Under the SA AED Act, a device installed in scope must be registered with the SA Ambulance Service within two weeks, and the register is integrated with Triple Zero. This isn’t a “nice to do” — it’s a legal step.
- Queensland and the ACT are the thin end. Queensland’s QAS registry records a device’s location but doesn’t run the nearby-responder alerting that GoodSAM does. The ACT has no government registry at all, so Canberra devices go on the St John national register instead.
What this means for a multi-state portfolio
The takeaway is simple: map each device to the right registry, and build the difference into your process.
- Don’t write a one-line “register on GoodSAM” step. It’s wrong for the NT, WA, SA, QLD and the ACT — which is most of the country.
- NT and WA devices go on the relevant St John platform. Treat them as their own pathway.
- NSW, VIC and TAS devices go on GoodSAM — familiar and consistent across those three.
- SA devices must be registered on the SA Ambulance register, on a legal two-week clock. This is the one with a deadline.
- QLD and ACT devices still get registered — QAS for Queensland, the St John national register for the ACT — even though the systems are thinner.
A national AED standard is a good idea. A national registration shortcut isn’t — the registries genuinely differ, and a device that’s “registered” on the wrong platform isn’t on the map that matters.
A practical approach
- List every device by state. That single column tells you which registry each one belongs on.
- Flag your SA devices first — they’re the only ones with a legal registration deadline.
- Group the rest by model: St John (NT, WA), GoodSAM (NSW, VIC, TAS), other (QLD, ACT).
- Write the registration step per group, not once for the whole portfolio.
- Keep every entry current — when pads or batteries are replaced, update the record on whichever platform the device lives on.
Where SafePulse fits
We supply, install and maintain AEDs across the Northern Territory and interstate, so we deal with all of these registries — St John NT’s First Responder app, St John WA’s State Defib Network, GoodSAM in the eastern states, and the mandatory SA Ambulance register. When we install a device we register it on the right platform for its state, and our maintenance plans keep both the device and its registration record current.
The two non-GoodSAM systems are written up individually — St John WA’s State Defib Network — alongside the GoodSAM model in registering an AED with NSW Ambulance. For the Territory position generally, see do Northern Territory commercial buildings need an AED in 2026 and our Northern Territory AED page.
