No one walked these tracks with a radio. A computer model combines laser-scanned terrain heights (NSW Spatial Services LiDAR), satellite-measured tree canopy, and the positions of repeaters the MeshSafe station has actually heard recently, then does radio line-of-sight maths at 915 MHz for every 15 m of every track.
Radio in bush terrain is messy. Wet leaves, your body between the radio and the hill, how you hold it, a repeater going offline overnight, rain — all of it moves real coverage in ways no model captures. Green means the maths is hopeful. It is not a measurement, and it is not a promise. Amber and red can be wrong in both directions too.
Post test on #meshsafe from the trailhead — a real radio check beats every prediction on this page. Never plan your safety around this map: tell someone your plans face-to-face, and carry a PLB for remote or solo trips. In an emergency call 000.
Set a return time. If you're not back and stay silent past it (plus 30 minutes' grace), your emergency contact gets an email.
First time here? Fill in these three so we know who to alert — no radio needed. Already registered with MeshSafe (radio or a previous walk)? Your email above is enough — leave these blank.
Works with or without a mesh radio. With one, adverts still check you in and leave breadcrumbs. Without one, the return time is the only thing watching over you — this is a courtesy net, not a rescue service. For remote or solo trips carry a PLB. Emergencies: 000.
