Outback Communication

Travelling in isolated locations doesn’t necessarily mean you’re isolated. There are several options for communicating in Outback Queensland, and it’s important to stay in touch in remote areas.

Mobile Coverage

Longreach, Mount Isa, Charleville and Birdsville have coverage from Telstra and Optus networks. Outside of these towns only the Telstra Next G network is available, usually within a 20km radius of towns. There is limited mobile phone coverage in the far South West corner of the region, west of Quilpie to Bedourie. Public phones are available in all towns, and satellite phones are recommended for extended travel in this area.

Satellite Phones

Sat phones connect to orbiting satellites rather than cell towers on the ground, giving access to communication in areas where there is no mobile coverage. There are a range of options available with varying degrees of performance versus cost, be sure to research the best option for your needs and your travel plans.

Thankfully there are easier ways of communicating than this display at the Quilpie Information Centre!

UHF CB is an abbreviation for Ultra High Frequency Citizen Band Radio, UHF CB Radio is freely available to all Australians and does not require a license or registration to use. Ensuring you can communicate from your vehicle to other vehicles in close proximity is essential for safety reasons (eg. warn oncoming vehicles when visibility is impaired), can aid in navigation (convoy procedures), and call to nearby travellers for help. Handheld or in-car UHFs are available, though radios have a limited range of around 5km to 20km and good reception is heavily dependent on terrain. Hilly or densely vegetated areas can reduce transmission considerably. Using this type of radio on a high hill or tower can also increase its range.
A handy list of properties and their UHF channels is included in the rear of the Atlas of QLD and NT Pastoral Stations, by Terrence Alick Mapping (http://alickmaps.com.au/).
