Best Personal Locator Beacons in Australia: Top 5 PLBs

Most of Australia has no mobile coverage. Once you leave the bitumen on the Plenty Highway, walk into a gorge in the Kimberley or launch a tinny off a remote boat ramp, your phone becomes a camera. If someone rolls an ankle on a scree slope or a vehicle rolls on a washout, you need a way to call for help that doesn't depend on a tower.

That is the job of a personal locator beacon. A PLB is a small, registered 406 MHz distress beacon that sends your position to search and rescue authorities through the Cospas-Sarsat satellite system. It needs no subscription, works across the country and can sit in a pack, a glovebox or a PFD pocket for years until the day it matters.

This guide covers the Australian rules, what separates one beacon from another, and our top five picks for the best personal locator beacon you can buy in Australia right now. Every model here is sold through Australian retailers and is coded for Australian registration.

Quick picks: best PLBs in Australia

• Best overall: GME MT610G, compact, with a 7 year battery and 6 year warranty.
• Best with return link: GME MT620GR, which adds Return Link Service and an app.
• Best battery life and warranty: KTI Safety Alert SA2GN, with a 10 year battery and 10 year warranty.
• Smallest and lightest: Ocean Signal rescueME PLB1, around 116g with a flotation pouch fitted for Australia.
• Best screen: ACR ResQLink View RLS, with a digital display.

How we picked

We have not tested these beacons. We compared published specs from the makers' manuals and tech sheets, warranty terms, Australian availability and pricing at Australian retailers, and independent Australian reviews. We only included models sold by Australian retailers for use in Australia. Each beacon was scored against this weighted rubric:

• Location performance, 25%: GNSS receiver (GPS, and Galileo where listed), published accuracy and how quickly a position is sent.
• Battery life and servicing, 20%: years until the battery must be replaced and the minimum operating time once activated.
• Warranty and Australian support, 20%: warranty length and whether the maker or distributor has a service network here.
• Size and weight, 15%: a beacon only helps if you carry it, so smaller and lighter scores higher.
• Features, 10%: Return Link Service, strobe, display, buoyancy, self-test options.
• Value, 10%: price at Australian retailers against the above.

Scores are out of 10 and reflect this rubric only.

The Australian rules for PLBs

Australia's distress beacon system is run by the Australian Maritime Safety Authority (AMSA).

It must be a 406 MHz digital beacon

AMSA states that 121.5 MHz distress beacons are no longer detected by satellite. You must carry a digital 406 MHz beacon. Most 406 MHz PLBs also transmit a low-power 121.5 MHz homing signal that rescue aircraft and vessels use to close in on you, which is normal.

Buy one made for the Australian market

PLBs sold in Australia need to meet the Australian and New Zealand standard AS/NZS 4280.2. The current edition was published in 2023. AMSA keeps a list of PLB models that, when bought in Australia, are known to meet the standard, and it notes that other compliant models may not yet appear on the list. AMSA does not endorse any brand.

Be careful with beacons bought overseas. AMSA warns that US-market PLBs send a Morse "P" on 121.5 MHz, which is not permitted under Australian Standards or the ACMA class licence, so they should not be used here. Any 406 MHz beacon registered with AMSA must also be coded with an Australian country code, and recoding an imported unit may be difficult. Buying from an Australian retailer avoids all of this.

Register it with AMSA

Registration is free and done online at beacons.amsa.gov.au or by phoning 1800 406 406. You need the beacon's 15-character HexID (also called the UIN), printed on the label. AMSA says that in some cases registration is mandatory by law and you may be fined if you can't prove your beacon is registered, so treat it as a must. Registration lasts two years and must be renewed before it expires. Update it if your contact details change, or if you sell, buy, lose or dispose of a beacon.

A registered beacon lets AMSA call your emergency contacts straight away, so keep your details and trip plans current.

GPS matters

AMSA's brochure gives a clear reason to buy a GPS beacon. With GPS, your position is typically sent to within about 120 metres within about 20 minutes. Without GPS, rescuers are working with an area of about 5km, and a position can take 90 minutes to 5 hours. All five beacons on this list have a built-in GNSS receiver.

PLB buyer's guide: what the specs mean

Battery life and service interval

PLB batteries are not like torch batteries. Each beacon has a battery expiry date marked on the housing, and the battery must be replaced by an authorised service centre by that date or after any emergency activation. Battery life on current models runs from 5 to 10 years. A longer interval means fewer service bills over the life of the beacon.

The other figure is operating time once activated. The makers quote a minimum of around 24 hours of transmission, usually at -20°C.

GNSS receiver

Every beacon here uses GPS. Some also list Galileo, the European system, which gives the receiver more satellites to work with.

Return Link Service

Return Link Service (RLS) is a newer feature on some beacons. After you activate the beacon, the satellite system sends a confirmation back to the beacon, and a light on the unit shows that your alert has been received. Knowing help is coming changes the decisions you make while you wait.

Water rating and buoyancy

Many PLBs are waterproof and some float, but they are not designed to transmit under water. GME's manual also notes that a PLB is not a substitute for a 406 MHz EPIRB and doesn't satisfy marine carriage requirements.

Size and weight

The beacons in this guide weigh between about 116g and 160g. A beacon only helps if it is on you, not left in the car.

1. GME MT610G: best overall

Score: 8.9/10

GME is an Australian company and the MT610G is its most compact beacon. It combines a solid service interval, a long warranty and Australian support at a fair price.

• 406 MHz with 121.5 MHz homing, Cospas-Sarsat Class 2 certified
• Built-in 72-channel GPS receiver (as listed in an Australian review)
• IP68: 10m of salt water for 1 hour
• Weight 160g, 88 x 66 x 36mm
• Battery life 7 years from date of manufacture, warranty 6 years
• Battery pack designed to meet UN requirements for carriage as non-hazardous cargo on passenger aircraft
• GME's suggested retail price is $379 at the time of writing (October 2026)

Why it made the list

The MT610G has no weak point on the rubric. Activation is two steps: raise the antenna, then hold the button for at least 2 seconds. The manual says the beacon waits about 50 seconds before it starts transmitting, which gives you a short window to cancel an accidental activation.

Pros

• Australian brand with local service and a 6 year warranty
• Compact and light enough for a belt or shoulder strap
• Strong price for the specs

Cons

• No Return Link Service
• At 160g it is heavier than the PLB1 and SA2GN
• The manual says it is not designed to operate in water, so keep the antenna clear if you go in

Best for

4x4 tourers, bushwalkers, farmers and motorbike riders who want a proven Australian beacon at a sensible price.

2. GME MT620GR: best with Return Link Service

Score: 8.7/10

The MT620GR shares the MT610G's size and warranty and adds confirmation that your alert has reached a rescue coordination centre.

• 406 MHz digital transmission at 5 watts, with 121.5 MHz homing
• GNSS receiver with Galileo, plus Return Link Service
• IP68 (tech sheet): 10m of salt water for 1 hour
• Weight 160g plus or minus 2g, 88 x 66 x 37mm
• Battery life 7 years, warranty 6 years
• High visibility strobe and buzzer
• Accusat Connect app for checking battery status and self-test results
• GME RRP $569, seen for around $499 at Australian retailers at the time of writing (October 2026)

Why it made the list

Return Link Service is the main reason to choose this beacon over the MT610G. A blue LED and buzzer show return link status while a red LED shows general activity. The app helps you keep track of self-tests and battery status between trips.

Pros

• Confirmation that your alert has been received
• Same compact body and 6 year warranty as the MT610G
• App support for battery and test status

Cons

• Costs well over $100 more than the MT610G
• Same 160g weight, so no saving in size

Best for

Solo travellers and anyone who wants to know their alert has gone through, such as remote station workers and solo hikers.

3. KTI Safety Alert SA2GN: best battery life and warranty

Score: 8.6/10

KTI is an Australian manufacturer, and the SA2GN stands out for its service interval. A 10 year battery and 10 year warranty are the longest of any beacon here.

• 406 MHz with 121.5 MHz homing for a minimum of 24 hours
• 66-channel GPS that updates your position every 5 minutes
• Battery replacement interval 10 years, or after emergency use
• 10 year warranty
• Weight about 140g, 88 x 64 x 31mm
• Strobe, whistle on the lanyard, and an NFC tag that shows the battery expiry date and HexID on a phone

Why it made the list

Over a decade, a 10 year battery means one fewer service visit than a 5 year beacon would need, which saves money and the risk of forgetting. Tap the NFC tag with your phone to read the HexID and battery date without hunting for the label.

Pros

• Longest battery interval and warranty in this guide
• Light and compact
• Australian-made with local service

Cons

• No Galileo or Return Link Service listed
• KTI's manual says the SA2GN was not designed or tested for operation in water
• Must be returned to KTI for battery replacement after any activation

Best for

Anyone who wants to buy once and leave it in the kit for a decade, such as farmers, prospectors and occasional travellers.

4. Ocean Signal rescueME PLB1: smallest and lightest

Score: 8.3/10

The rescueME PLB1 is the smallest beacon in this guide, small enough for a PFD pocket or a running belt. Units supplied to Australia have a flotation pouch permanently attached to meet local rules.

• 406 MHz with 121.5 MHz homing
• Built-in GNSS receiver
• Weight about 116g, 77 x 51 x 32.5mm (manufacturer spec sheet)
• Battery replacement interval 7 years, or after emergency activation
• Operating life more than 24 hours at -20°C
• Waterproof to 15m, high-intensity strobe
• Warranty: Ocean Signal lists 2 years, extended by 3 years when you register the product within 90 days
• Seen for around $440 to $460 at Australian retailers at the time of writing (October 2026)

Why it made the list

The PLB1 is around 40g lighter than the GME pair, and the Australian version comes with the flotation pouch fitted, so it suits paddlers and boaties as well as walkers.

Pros

• Smallest and lightest in this guide
• 7 year battery interval
• Waterproof to 15m with flotation pouch fitted for Australia

Cons

• Shorter standard warranty unless you register it with Ocean Signal
• Battery can only be replaced by an authorised Ocean Signal centre
• No Return Link Service

Best for

Kayakers, trail runners, mountain bikers and anyone counting grams.

5. ACR ResQLink View RLS: best screen

Score: 8.0/10

The ResQLink View RLS (model PLB-435) is the only beacon here with a digital display. It shows your GPS coordinates and beacon status, and it includes Return Link Service.

• 406 MHz with 121.5 MHz homing
• GPS and Galileo, with Return Link Service
• Digital display for coordinates and beacon status
• Weight about 148g, 114.8 x 51.6 x 37.8mm
• Battery life 5 years, operating life listed at 28 hours
• Waterproof to 5m for 1 hour, buoyant
• Seen for around $550 at Australian retailers at the time of writing (October 2026)

Why it made the list

The display is the selling point. If you have radio or phone contact, you can read your coordinates off the screen and pass them on. ACR lists AMSA (Australia) among the View RLS approvals, and it is stocked by Australian retailers.

Pros

• Clear screen with coordinates and status
• Return Link Service and Galileo
• Buoyant

Cons

• Shortest battery interval in this guide at 5 years
• Most expensive pick
• Battery replacement must be done by an authorised service provider; one Australian retailer was quoted around $200 for an ACR battery replacement
• ACR's manual says it will not work submerged

Best for

Boaties, pilots and tech-minded walkers who want to see their position and beacon status at a glance.

PLB comparison table

Which PLB should you buy?

• If you want one proven beacon for touring and walking, get the GME MT610G.
• If you often travel alone and want confirmation your alert went through, get the GME MT620GR or the ACR ResQLink View RLS.
• If you want the lowest running cost over 10 years, get the KTI SA2GN.
• If you paddle, run or ride and weight is everything, get the Ocean Signal rescueME PLB1.
• If you want to read your coordinates off a screen, get the ACR ResQLink View RLS.
• If you go offshore, carry the EPIRB your state requires and add a PLB as a personal extra.

A PLB is one-way: you can't talk to anyone through it. Our guide to picking the best UHF radios covers vehicle-to-vehicle communication, and our emergency survival radio guide covers receiving warnings and broadcasts.

How to use and look after your beacon

In a real emergency

AMSA's advice is to use two-way communication first if you have it, such as a phone call to 000 or a radio call, because you can describe your situation. When that isn't possible and life is at risk, activate the beacon.

• Move to open ground with a clear view of the sky if you can. Satellites can't pick up a beacon through hills, thick trees or buildings, and AMSA notes that in a valley you may need to wait for a passing satellite.
• Extend the antenna and keep it vertical, following the manual.
• Leave the beacon on. AMSA says not to switch it off until rescue services tell you to.

AMSA notes that on land, state and territory police coordinate search and rescue.

If it goes off by accident

Switch the beacon off straight away and call AMSA on 1800 641 792 so the search can be stood down. AMSA says there is no penalty for accidental activation. If the beacon was activated in an aircraft, AMSA lists 1800 815 257. Expect AMSA to try to contact you or your emergency contacts if they detect a signal, so keep your phone numbers current.

Testing and storage

• Use the self-test only as often as the manual says. GME recommends no more than 2 self-tests a month, and KTI suggests a GPS self-test no more than twice a year because each test uses battery power.
• Check the battery expiry date on the label each year and book the service early.
• Store the beacon where you can reach it, not buried in a drawer in the camper. A pack strap, a belt pouch or a dash cubby works well.

Travelling overseas

AMSA warns that some countries consider carrying or activating a PLB on land illegal, and airlines have differing rules, so check before you go.

Disposal

Never put an old beacon in the bin, as AMSA says it can activate at the tip. Ask a local battery store (a small fee may apply), then update your AMSA registration.

While you are packing safety gear, a small 12V repair kit with a Solderstick connector kit is worth a spot next to the beacon, because a fixed wiring fault can keep you moving and out of trouble in the first place. Our roadside 12V repair kit guide covers what to carry.

Conclusion

For anyone heading beyond mobile coverage, a registered 406 MHz PLB is essential safety gear. The GME MT610G is our top pick for its balance of size, battery life, warranty and price. Choose the MT620GR or ACR ResQLink View RLS if you want Return Link confirmation, the KTI SA2GN for the longest service interval, or the rescueME PLB1 if every gram counts.

Whichever best personal locator beacon suits your trips, buy it from an Australian retailer, register it with AMSA before your first trip, keep the registration current and carry it on your body, not in the car. For more trip preparation, read getting ready for your first off-road trip in a 4x4.

Frequently asked questions

Do I have to register my PLB in Australia?

AMSA says registration is mandatory by law in some cases and you may be fined if you can't prove your beacon is registered. Registration is free, takes a few minutes online and lets AMSA contact your emergency contacts quickly. Treat it as essential and renew it every two years.

Can I use a PLB I bought overseas?

AMSA advises against US-market PLBs because they send a Morse "P" on 121.5 MHz, which is not permitted in Australia. A beacon registered with AMSA must also be coded with an Australian country code. Buy from an Australian retailer to make sure you get a correctly coded beacon.

What is the difference between a PLB and an EPIRB?

Both are 406 MHz distress beacons. An EPIRB is registered to a vessel, while a PLB is carried by a person on land or water. GME notes that a PLB doesn't satisfy Australian marine carriage requirements in place of an EPIRB.

Does the best personal locator beacon need a subscription?

No. PLBs use the Cospas-Sarsat system with no subscription. The running cost is a battery replacement every 5 to 10 years, depending on the model.

What should I do if I set off my beacon by mistake?

Switch it off immediately and call AMSA on 1800 641 792. AMSA says there is no penalty for an accidental activation. The call lets them stand down any search.

Is a smartphone with satellite SOS a replacement for a PLB?

A phone with satellite SOS is a useful backup, but it relies on a charged battery and a commercial service, and it is not a registered 406 MHz beacon. For remote travel, carry a registered PLB and treat phone features as an extra.
