Navigation Tips for the Australian Bush
The Australian bush offers incredible adventures, but it also demands respect and preparation. Getting lost can have serious consequences, so mastering navigation skills is paramount. This guide provides essential tips and techniques to help you stay safe and on course while exploring the Australian wilderness. Remember to always tell someone where you are going and when you expect to be back.
1. Map Reading Basics
A map is your primary source of information about the terrain. Understanding how to read and interpret a map is crucial for effective navigation.
Understanding Map Symbols
Maps use symbols to represent various features such as roads, rivers, buildings, and vegetation. Familiarise yourself with the legend on your map to understand what each symbol represents. Topographic maps also use contour lines to indicate elevation changes. Closely spaced contour lines indicate steep slopes, while widely spaced lines indicate gentle slopes.
Orienting the Map
Before you can use a map effectively, you need to orient it. This means aligning the map with the terrain. Use a compass to find north and then rotate the map until north on the map points in the same direction as north on your compass. Once the map is oriented, you can easily identify features around you.
Determining Your Location
There are several ways to determine your location on a map. One method is to identify two or more prominent features in the landscape and then locate those features on the map. By taking bearings to these features with your compass, you can pinpoint your location using triangulation. Another method is to use a GPS device to obtain your coordinates and then locate those coordinates on the map. Remember to check frequently asked questions about map reading if you're unsure.
Common Mistakes to Avoid
Not orienting the map: Trying to navigate with a map that isn't oriented is a recipe for disaster.
Misinterpreting map symbols: Always refer to the legend to ensure you understand what each symbol represents.
Ignoring contour lines: Contour lines provide valuable information about the terrain. Pay attention to them to avoid unexpected obstacles.
2. Compass Usage Techniques
A compass is an indispensable tool for navigation, especially in areas where visibility is limited or GPS signals are unreliable.
Understanding Compass Components
A compass consists of several key components, including a magnetic needle, a baseplate, a rotating bezel, and a direction-of-travel arrow. The magnetic needle always points towards magnetic north. The baseplate is used for taking bearings and measuring distances on a map. The rotating bezel is used to set the desired bearing. The direction-of-travel arrow indicates the direction you should walk in.
Taking a Bearing
To take a bearing to a distant object, hold the compass level and point the direction-of-travel arrow towards the object. Rotate the bezel until the north end of the magnetic needle aligns with the orienting arrow on the bezel. The bearing to the object is indicated by the degree marking on the bezel.
Following a Bearing
To follow a bearing, rotate the bezel to the desired bearing. Hold the compass level and turn your body until the north end of the magnetic needle aligns with the orienting arrow on the bezel. The direction-of-travel arrow now indicates the direction you should walk in. Choose a landmark in that direction and walk towards it. Repeat this process as needed to stay on course.
Declination Adjustment
Magnetic north is different from true north. The difference between these two is called declination. Declination varies depending on your location. Most topographic maps indicate the declination for the area covered by the map. Before using your compass, you need to adjust for declination to ensure accurate bearings. Some compasses have an adjustable declination, while others require you to manually add or subtract the declination angle from your bearings. Warriorgear can provide advice on selecting the right compass for your needs.
Common Mistakes to Avoid
Ignoring declination: Failing to adjust for declination can lead to significant errors in your navigation.
Holding the compass near metal objects: Metal objects can interfere with the magnetic needle and cause inaccurate readings.
Not keeping the compass level: An unlevel compass can also produce inaccurate readings.
3. GPS Device Navigation
GPS devices can be valuable tools for navigation, but they should not be relied upon as your sole means of navigation. Batteries can fail, signals can be lost, and devices can malfunction.
Understanding GPS Coordinates
GPS devices use coordinates to pinpoint your location on the earth. Coordinates are typically expressed in latitude and longitude. Latitude measures the distance north or south of the equator, while longitude measures the distance east or west of the prime meridian. Make sure you understand the coordinate system your GPS device uses (e.g., decimal degrees, degrees/minutes/seconds).
Waypoints and Routes
GPS devices allow you to create waypoints, which are specific locations that you want to navigate to. You can also create routes, which are a series of waypoints that you want to follow in a specific order. Before your trip, create waypoints for your destination and any other important locations along your route. During your trip, use your GPS device to navigate to these waypoints and follow your route.
Downloading and Using Maps
Many GPS devices allow you to download and use maps. These maps can provide valuable information about the terrain, such as roads, rivers, and elevation changes. Make sure you download the appropriate maps for the area you will be exploring. Also, ensure you know how to use the maps on your device effectively.
Battery Management
GPS devices consume a lot of battery power. To conserve battery life, turn off unnecessary features, such as Bluetooth and Wi-Fi. Carry extra batteries or a portable power bank. Consider a solar charger for extended trips. Regularly check the battery level of your GPS device and recharge it whenever possible.

Common Mistakes to Avoid
Relying solely on GPS: Always carry a map and compass as backup in case your GPS device fails.
Not understanding GPS coordinates: Make sure you understand the coordinate system your GPS device uses.
Ignoring battery life: Regularly check the battery level of your GPS device and conserve power when possible.
4. Natural Navigation Methods
In situations where you don't have a map, compass, or GPS device, you can use natural navigation methods to find your way.
Using the Sun
The sun rises in the east and sets in the west. By observing the sun's position, you can get a general sense of direction. In the Southern Hemisphere, the sun will be to your north at midday.
Using the Stars
At night, you can use the stars to navigate. The Southern Cross constellation points towards the south. To find south, locate the Southern Cross and extend a line from the long axis of the cross about four and a half times its length. This point will be close to the south celestial pole.
Observing Vegetation
Vegetation can also provide clues about direction. In general, moss tends to grow on the south side of trees in the Southern Hemisphere, as this side is typically shadier and moister. However, this is not always a reliable indicator, as local conditions can affect moss growth. Also, consider what we offer in terms of survival skills training.
Using Animal Trails
Animal trails often lead to water sources or other important locations. By following animal trails, you may be able to find your way back to civilisation. However, be aware that animal trails can also be dangerous, as they may lead to encounters with wildlife.
Common Mistakes to Avoid
Relying on a single indicator: Natural navigation methods are not always accurate. Use multiple indicators to confirm your direction.
Ignoring local conditions: Local conditions can affect the accuracy of natural navigation methods.
Assuming animal trails are safe: Be aware that animal trails can be dangerous.
5. Route Planning and Preparation
Before embarking on any bushwalking trip, it is essential to plan your route carefully and prepare accordingly.
Studying Maps and Guidebooks
Study maps and guidebooks of the area you will be exploring. Identify potential hazards, such as steep cliffs, deep rivers, and dense vegetation. Plan your route to avoid these hazards. Also, identify potential campsites and water sources.
Checking Weather Conditions
Check the weather forecast before your trip. Be prepared for changes in weather conditions. Carry appropriate clothing and gear for all types of weather. If severe weather is predicted, postpone your trip.
Notifying Someone of Your Plans
Tell someone where you are going and when you expect to be back. Provide them with a detailed itinerary of your route. If you change your plans, notify them as soon as possible. This is crucial for search and rescue efforts if you become lost or injured.
Packing Essential Gear
Pack essential gear, including a map, compass, GPS device, first-aid kit, food, water, shelter, and communication device. Ensure your gear is in good working order and that you know how to use it.
Common Mistakes to Avoid
Not planning your route: Failing to plan your route can lead to unexpected difficulties and delays.
Ignoring weather conditions: Being unprepared for weather changes can be dangerous.
Not notifying someone of your plans: This can significantly delay search and rescue efforts if you become lost.
6. Emergency Navigation Strategies
Despite your best efforts, you may still become lost in the bush. In such situations, it is important to remain calm and implement emergency navigation strategies.
Stay Calm and Assess the Situation
The first thing to do when you realise you are lost is to stay calm. Panic can cloud your judgment and lead to poor decisions. Take a deep breath and assess the situation. Try to remember your last known location and how you got lost.
Retrace Your Steps
If possible, retrace your steps back to your last known location. Look for familiar landmarks or signs of your passage. If you can't retrace your steps, try to find a high point where you can get a better view of the surrounding terrain.
Signal for Help
If you are unable to find your way back, signal for help. Use a whistle, mirror, or brightly coloured clothing to attract attention. Build a fire to create smoke. If you have a communication device, use it to call for help. Provide your location and a description of your situation.
Find Shelter and Water
While waiting for help, find shelter and water. Shelter will protect you from the elements, while water is essential for survival. Look for a natural shelter, such as a cave or rock overhang. If you can't find a natural shelter, build one using branches and leaves. Collect rainwater or find a water source, such as a stream or spring. Purify any water before drinking it.
Conserve Energy
Conserve energy by avoiding unnecessary exertion. Stay warm and dry. Ration your food and water. Wait for help to arrive.
Common Mistakes to Avoid
Panicking: Panic can lead to poor decisions.
Wandering aimlessly: Wandering aimlessly wastes energy and makes it harder to find you.
Not signalling for help: Signalling for help is crucial for attracting attention.
