Everything You Need to Know About PLBs (And Whether You Need One)
Let’s face it—Australia is massive. And remote. Whether you're trekking in Tassie, fishing off the NT coast, or bouncing through the Pilbara in your 4WD, help can be a long way off. That’s where a Personal Locator Beacon (PLB) steps in.
In this guide, we’ll break down what a PLB actually is, why you might want one (yep, even if you think of yourself as the next Bear Grylls), and how they can be a lifesaver should you get into strife whilst out on the road.
So, What Exactly Is a PLB?
A PLB (or Personal Locator Beacon) is a small, pocket-sized emergency device that lets you call for help if things go pear-shaped. Once activated, it beams out a distress signal using the 406 MHz frequency, picked up by a global satellite network called COSPAS-SARSAT. Sounds fancy, but in reality its dead simple.
Your GPS coordinates are fired off to emergency services. In Oz, that’s the Australian Maritime Safety Authority (AMSA). They coordinate the rescue and, hopefully, get to you before things get worse. Some PLBs even include a homing signal to help crews find you more precisely.
Who Should Own a PLB? (Spoiler: It’s Not Just Hardcore Bushwalkers)
Honestly? Pretty much anyone who ditches the city now and then. If you go remote, even just occasionally, it’s a smart bit of kit that can provide a vital lifeline.
If you identify with any of the following, you should probably own a PLB…
- Bushwalkers and hikers
- 4WDers and outback tourers
- Tradies and station workers on rural properties or minesites
- Grey nomads on the big lap
- Fishos and boaters (although for boating offshore, an EPIRB might be required)
Even if you’re a seasoned traveller, all it takes is one injury, or dodgy weather system to make you wish you'd packed that beacon.
Why a PLB Makes Sense in the Middle of Nowhere
Let’s be real: mobile reception is a luxury once you’re off the grid. Telstra and Optus might cover the highways and bigger towns, but head out into the desert, high country, or deep bush and suddenly your phone's just dead weight. That’s where a PLB steps in—no towers, no signal bars, no worries.
Whether you’re remote camping near Birdsville, trail running in the Blue Mountains, or cruising between roadhouses in the Top End, a PLB means you’re never truly cut off. Accidents don’t check for coverage areas before they strike.
Here’s what makes a PLB a no-brainer:
- Works without signal (zero bars? No worries.)
- Covers remote parts of Aus via satellite
- Sends your GPS straight to authorities
- One-off cost, no subscription dramas
- Reassures the folks back home, especially when you’re travelling solo or in a tiny crew
Think of it as your lifeline—one you hope to never use, but will be bloody glad to have if you need it.

FAQs: What Aussies Want to Know About PLBs
What is a PLB?
A Personal Locator Beacon is a portable device that allows you to send an emergency distress signal via satellite when you're in a life-threatening situation. It transmits your GPS coordinates directly to Australian rescue authorities, giving you the best chance of being located and helped quickly—even in the most remote parts of the country.
Should I get a PLB or an EPIRB?
PLBs are designed for use on land and are ideal for hikers, campers, and remote workers. EPIRBs are intended for marine use and are often legally required on boats. If you’re on land, a PLB is usually your best option; on water, make sure you check your legal obligations.
How does a PLB work?
When activated, a PLB sends a coded message via satellite to the Australian Maritime Safety Authority (AMSA). This message includes your unique ID and, in most cases, your GPS location. AMSA then coordinates a rescue response based on your location and the contacts you’ve listed during registration.
Do I need phone reception for it to work?
Not at all. PLBs use satellites, not mobile networks, which means they work virtually anywhere on the planet—even where there’s no phone signal. That’s what makes them so crucial in the outback or other remote areas.
Do I have to pay a subscription?
Nope. PLBs like the rescueME PLB1 don’t require any ongoing fees. You just buy the unit, register it with AMSA, and you’re good to go. Some other devices (like satellite messengers) do require subscriptions, but PLBs keep it simple.
How do I register my PLB?
You need to register your PLB with AMSA at https://beacons.amsa.gov.au. You’ll provide your beacon’s ID number, your contact details, and emergency contact info. It’s free and ensures emergency services have the right info to respond quickly.
Can I take it fishing or boating?
You can, especially if you're staying close to shore or combining land and water activities. The rescueME PLB1 is waterproof and includes a float pouch. However, if you're boating offshore, an EPIRB may be required by law, so always check marine safety regulations in your state.
How long will the battery last?
Most PLBs have a battery shelf life of around 7 years. Once activated in an emergency, they’ll typically transmit for at least 24 hours straight—plenty of time for help to arrive, especially with accurate GPS positioning.
Is a PLB really worth it?
Absolutely. For the cost of a weekend away, you’re buying a device that could literally save your life. It's especially worth it for solo travellers, families with kids, or anyone heading into places where help isn’t immediately available.
Where do I buy one?
You can buy a PLB online through trusted Aussie suppliers. We recommend the rescueME PLB1 because it’s compact, waterproof, and ready for anything Australia throws at it.
How's a satellite messenger different?
A satellite messenger offers more than just SOS—it usually includes two-way texting and tracking features. But they come with a monthly fee and often require app connectivity. A PLB, on the other hand, is built solely for emergencies and doesn’t rely on phones or subscriptions. It’s a more rugged, reliable choice when all you need is to be found—fast.
Final Thoughts
In a country as big, bold and remote as Australia, having a PLB with you isn’t overkill — it’s common sense. Whether you're trekking through Tassie or crossing the Nullarbor, don’t leave safety to chance.
Want that extra layer of protection? Get yourself a rescueME PLB1 and head off with peace of mind.
