When you’re travelling through remote Australia, mobile phone coverage disappears faster than a cold beer at a caravan park happy hour. Whether you’re exploring the Nullarbor, wandering through the Kimberley, or camping in Tasmania’s wilderness, emergency communication gear isn’t just nice to have — it could save your life.
This guide covers everything from satellite messengers to UHF radios, helping you choose the right emergency communication setup for your big lap. We’ve tested these devices in real-world conditions across Australia’s most remote regions.
Why Emergency Communication Gear Matters
Australia is massive, and mobile phone coverage covers only about 30% of the continent. The moment you head off the beaten track — which is exactly where the best camping spots are — you’re on your own. Medical emergencies, vehicle breakdowns, or getting lost can quickly turn dangerous without a way to call for help.
Emergency communication gear serves three critical purposes:
- Emergency SOS: Summoning help when everything goes wrong
- Check-ins: Letting family know you’re safe
- Weather updates: Critical for avoiding dangerous conditions
Don’t rely solely on mobile phone coverage maps. They often show theoretical coverage that doesn’t match real-world experience, especially in valleys or dense bush.
The most common scenarios where caravanners need emergency communication include medical emergencies (heart attacks, snake bites, accidents), vehicle breakdowns in remote areas, getting lost or bogged, and severe weather events. Having multiple communication options dramatically increases your chances of getting help when you need it most.
Types of Emergency Communication Devices
Satellite Messengers
These compact devices send text messages and SOS alerts via satellite networks. They’re the most popular choice for recreational travellers because they’re affordable, easy to use, and provide two-way communication. Battery life typically lasts 2-4 weeks with regular use.
Popular models include the Garmin inReach series $299-$449 and the SPOT devices $149-$249. The key advantage is low ongoing costs (typically $15-30/month) and the ability to send custom messages to multiple contacts.
Satellite Phones
True satellite phones provide voice calling anywhere on Earth. They’re more expensive to buy and operate but offer the most comprehensive communication capability. Battery life is shorter (8-16 hours talk time) but they charge quickly.
The two main networks are Iridium (true global coverage) and Inmarsat (coverage everywhere except polar regions). Iridium works better in Australia’s remote areas because it uses low-orbit satellites that penetrate tree cover more effectively.
UHF CB Radios
UHF radios provide short-range communication (5-15km depending on terrain) and are essential for convoy travel. They’re also monitored by emergency services in many remote areas. Channel 10/11 is the unofficial tourist channel, while Channel 40 is monitored by emergency services.
Every caravan should have UHF capability, either handheld or vehicle-mounted. They’re also useful for communicating with other caravanners, getting local information, and staying in touch during day trips away from your van.
EPIRB (Emergency Position Indicating Radio Beacon)
EPIRBs are SOS-only devices that send your exact location to emergency services. They’re registered to you personally and have a 10-year battery life. When activated, they broadcast continuously for 24-48 hours and guarantee a rescue response.
The main limitation is they’re one-way communication only — you can’t send custom messages or receive confirmations. They’re best used as backup to other communication methods.
- Coverage area: Ensure the device works in your planned travel areas
- Two-way capability: Can you receive confirmations and replies?
- Battery life: How long between charges with typical use?
- Monthly costs: Factor in ongoing subscription fees
- Message types: Pre-set messages, custom text, or voice calling?
- Durability: IP67 or better water/dust resistance rating
- Ease of use: Can you operate it under stress or in poor conditions?
- Emergency response: 24/7 monitoring and guaranteed rescue coordination

Ongoing Service Costs
Emergency communication devices typically require monthly subscriptions for satellite access. Here’s what you can expect to pay:
Garmin inReach Plans
- Safety Plan: $19.95/month – 10 messages included
- Recreation Plan: $29.95/month – Unlimited preset messages, 40 custom messages
- Expedition Plan: $79.95/month – Unlimited messaging

- SMS: $0.50 per message
SPOT Plans
- Basic: $14.95/month – SOS and check-in only
- Unlimited: $24.95/month – Unlimited messaging
You can suspend most satellite subscriptions when not travelling. Garmin charges $4.99/month to suspend service, while SPOT offers free seasonal suspensions.
Installation and Setup Tips
Getting the best performance from your emergency communication gear requires proper setup and understanding how to use it effectively.
Satellite Device Placement
Satellite messengers and phones need a clear view of the sky to function. In your caravan, mount the device or external antenna on the roof or use a temporary magnetic mount. Thick caravan walls, especially those with metal framing, will block satellite signals completely.
For handheld units, step outside and hold the device above your head with the antenna pointing up. Trees, mountains, and even thick clouds can interfere with satellite communication, so be patient and persistent.
UHF Radio Installation
Mount the UHF radio where it’s easily accessible while driving. The antenna is critical — a properly installed roof-mounted antenna will dramatically outperform a magnetic antenna. Channel 10/11 is the standard for tourist information, while Channel 40 is monitored by emergency services in most areas.
Test your radio regularly and understand how to operate it under stress. Practice using it before you need it for an emergency.
Emergency Procedures
Create an emergency communication plan before you travel:
- Program important contacts into your devices
- Share your device contact information with family
- Establish regular check-in schedules
- Know how to activate SOS functions on each device
- Carry backup power sources for all devices
Register your EPIRB with ACMA (Australian Communications and Media Authority) and keep your contact details updated. False EPIRB activations can result in rescue cost recovery fees.
Testing and Maintenance
Test your emergency communication gear monthly. Send test messages, check battery levels, and verify that family members receive your communications. Keep firmware updated on satellite devices and replace batteries in EPIRBs before their expiry date.
Carry spare batteries or power banks for rechargeable devices. Cold weather significantly reduces battery performance, so keep devices warm in winter conditions.
