Zello is a high-speed, push-to-talk (PTT) walkie-talkie application that has become a staple for group coordination across Australia
"Got your ears on, Australia? Over."
Note: Do not rely on Zello for life-or-death emergencies if you have zero cell signal. It is not a satellite device. For true outback survival, carry a Garmin inReach or EPIRB. zello+channels+australia
