The Art of Navigation — Maps, Compass, GPS and Nature

In the age of Google Earth, GPS watches and pre-loaded topo apps, the art of bush navigation is being lost. Which is fine, until your batteries die, your sat reception drops out, or your phone takes an unplanned swim in a creek. Then you'll wish you'd kept up the scout-troop skills. Rule one of bush navigation: never rely on electronics alone. They fail in real conditions — flat batteries, wet weather, dropped sat reception, dodgy base maps. The smart approach is electronics + a paper map + the ability to navigate without either when you have to. Here's how to learn each layer.

Take a course — or three You can read every navigation article on the internet and still not be able to use a compass under pressure. The skill is muscle memory and decision-making — both of which need real practice with someone who knows what they're doing. Where to learn: Orienteering Australia (orienteering.asn.au) and your state body run skills sessions and beginner-friendly events almost every weekend TAFE Outdoor Education courses often include navigation modules Specialist providers: Aussie Survival Instructors, Climbing Adventures, Outdoor Training College, Bushlore Australia, Bob Cooper Survival Bushwalking clubs via Bushwalking Australia (bushwalkingaustralia.org) — many run navigation training for members Different activities need different navigation skills — sailing, snowsports and bushwalking all use the basics differently. Pick a course that matches what you'll actually be doing. 2. Topographic maps — the foundation A topographic map (topo) shows the shape of the land — contours, ridges, valleys, water features, vegetation types, tracks, fences. For bush navigation in Australia: 1:25,000 scale — most detail; ideal for serious bushwalking and remote travel 1:50,000 scale — broader coverage; ideal for vehicle-based touring and longer hikes 1:100,000 scale — overview; useful for trip planning rather than navigation in the field Where to buy: mapshop.com.au and melbmap.com.au are the main online retailers. Hema produces excellent road and 4WD-specific maps. Geoscience Australia provides government topos for the whole country (some downloadable free). Always: Buy or print the map laminated, or in a waterproof map case Note the map scale and the magnetic declination for the area (printed on the map) Know which direction is north on the map (always at the top, by convention) Practice "thumb tracking" — keep your thumb on your current location as you move Photo: Sylwia Bartyzel / Unsplash 3. The compass — simpler is better Don't be wooed by fancy-looking compasses with sighting mirrors and inclinometers. For 95% of bush navigation, a basic baseplate compass is what you want. Brand: Silva is the global standard. Make sure you buy one rated for the southern hemisphere — they're calibrated differently from northern hemisphere compasses, and using the wrong one introduces small errors that compound over distance. Five core compass functions: Heading — what direction you're currently travelling Bearing — what direction a landmark is from you Following a straight line — staying on a chosen heading despite obstacles Orienting a map — turning the map so it matches the real-world directions Triangulation — using bearings to two known landmarks to pinpoint your location on a map Each of these is a 30-minute lesson by itself. Don't try to learn them all at once — get one solid first, practice it on a known walk, then add the next. 4. GPS — useful, but not a replacement A handheld GPS (or GPS-enabled phone with offline maps) is genuinely useful in the bush. It tells you exactly where you are, lets you save waypoints, and can navigate you back along the route you came in on. Three things have to be true for it to work: You have clear sky for the satellites to triangulate your position You have battery life You know how to use it (not just the basics — the actual route-planning + bearing-to-waypoint stuff) Popular Aussie units: Garmin GPSMAP 66 series — bombproof, big screen, supports Aussie topo maps Garmin inReach Mini 2 — adds 2-way sat messaging and SOS for emergencies Garmin Fenix watches — wrist GPS for runners, hikers, kayakers Phone apps: Avenza Maps, Hema, Gaia, Locus Maps — all support offline georeferenced topos Carry lithium AA spare batteries (last longer than alkaline, work better in cold). Always carry a paper backup. Photo: Denise Jans / Unsplash 5. Nature's navigators — when everything else fails Map gone, GPS dead, compass needle broken. There's still a way to figure out roughly which way is which using just the sun, your watch, and the night sky. These won't get you onto an exact bearing, but they'll keep you walking in the right general direction. The shadow stick — push a straight stick vertically into level ground. Mark the tip of the shadow with a small rock. Wait 15 minutes. Mark the new tip position with another rock. The line between the two rocks runs roughly east-west — first rock is west, second rock is east. Stand with your feet on the line; you're facing roughly north. Your watch (analogue) — point the 12 o'clock mark at the sun (use 1 o'clock if it's daylight saving). Imagine a line bisecting the angle between 12 and the hour hand. That line points roughly north-south. South is the side closer to the sun's position. The Southern Cross — the southern hemisphere's classic night-time navigation aid. Find the Southern Cross constellation (4 main stars + 2 "pointer" stars off to one side). Three methods to find south, all giving roughly the same result: Length-of-cross method: extend an imaginary line from the top star through the bottom star of the cross. Continue along that line a distance of 4.5x the length of the cross. The point on the sky where you arrive is the South Celestial Pole — drop your arm straight down to the horizon. You're pointing south Through the pointers method: draw an imaginary line top-to-bottom through the cross. Draw another perpendicular to (and through the midpoint of) the line connecting the two pointer stars. Where the two lines cross is the South Celestial Pole. Drop arm to horizon = south Halfway-to-Achernar: extend the long axis of the cross to a bright star called Achernar. Hold one hand pointing at the top star of the cross, another pointing at Achernar; bring your hands together — that point is the South Celestial Pole. Drop down to horizon = south Once you're facing south: north is behind you, east is to your left, west is to your right. Source for the Southern Cross techniques: CSIRO. 6. Pre-trip preparation — the unsung hero Most navigation problems are prevented at the kitchen table, not solved in the field. Before any serious trip: Read up on the destination — bushwalking forums, trip reports, blog accounts. People who've done your route flag the common navigation traps Read the relevant guidebook — Bushwalking Australia (bushwalkingaustralia.org) lists reputable publishers Print or buy the right-scale topo map in advance — don't expect mobile reception to download maps at the trailhead Plan your bearings before you leave — work out the headings between major waypoints at home, with a compass, on the map. Mark the bearings and distances on the map itself Lodge a trip plan — tell a mate exactly where you're going, expected return time, and what to do if you don't return Carry a PLB in remote country (Personal Locator Beacon — see our PLB / signalling guide) Our take The minimum kit for any off-trail or remote bush walking: paper topo map (in waterproof case), Silva baseplate compass, GPS or phone with offline maps as backup, and the actual skill to use all three. The skill is the hard bit. The gear is cheap by comparison. Take an orienteering course or two, practice on known walks before you commit to remote ones, and never let yourself become entirely dependent on the electronic stuff. The bush rewards self-reliance.
