Look for water sources by following wildlife or vegetation
When looking for water sources in the Australian desert, it is important to follow wildlife or vegetation. Water is a vital resource, and the ability to find it can be a matter of life and death.
Following Wildlife
Animals can be a good indicator of nearby water sources, as they require water to survive, just like humans. Look out for animal tracks or trails, especially those leading downhill, as water often accumulates in canyons or valleys. Keep an eye on the sky for circling birds, and listen for birdsong. Birds that eat grain are typically found near water, and swarms of flies or mosquitoes can also indicate a water source. Bees tend to fly in straight lines between water sources and their hives.
Following Vegetation
Vegetation can also lead you to water. Most trees and dense vegetation cannot survive without a steady water source. If you are unsure about the local vegetation, look for the greenest plants, as these are more likely to indicate a water source. Deciduous and wide-leafed trees are usually a better sign of water than pine trees, as they require more water.
In the Australian desert, keep an eye out for specific vegetation that can indicate water sources. Desert oak placement, for example, can reveal deeper water table patterns, while mulga tree distribution often points to areas of reliable subsurface moisture. The presence of bush tomatoes often indicates water accessible through traditional digging techniques. Native fig growth patterns can lead to permanent underground water sources, and the presence of pigface plants often means fresh water can be accessed through shallow wells.
In general, look for bulges and cracks in the ground that may indicate tree roots, and dig near these. Digging for water can be time-consuming and tiring, so it is best to avoid direct sunlight and wait until the evening. Look for wet sand or mud, dig a hole, and wait for water to seep in.

Conserve water and energy by finding shelter and shade
If you find yourself in a survival situation in the Australian desert, your top priority should be to conserve water and energy. The most important thing you can do is to find shelter and shade, especially during the hottest parts of the day. Here are some detailed instructions to guide you through this challenging situation:
Finding Shelter and Shade
Look for shady areas that provide protection from the intense sun, such as depressions or overhanging rocks. If you have access to a shaded car, stay in it during the day. If not, create your own shelter by stringing cords between objects in a shaded area and draping sturdy emergency blankets over the cords. Place some brush on top of the blanket and cover it with another blanket or a thin Mylar sheet to insulate the shelter, keeping it cooler. Build this shelter in the evening or at night to avoid trapping heat inside. Alternatively, seek out existing natural shelters like rock overhangs or caves, but approach with caution as they may already be occupied by animals.
Conserving Water and Energy
Once you have found shelter and shade, limit your physical activity and keep exertion to a minimum. Slow down your movements and make them methodical to conserve energy. Stay put unless you are certain you know how to navigate to safety within a reasonable distance and time frame. Avoid removing clothing, as this can increase evaporation and water loss through sweating. Cover as much skin as possible with loose, lightweight clothing to trap sweat and slow down evaporation. Wear a light windbreaker over your clothing for additional protection.
Minimising Sweating
Keep your skin out of direct sunlight to prevent sweating and sunburn. If possible, become nocturnal, travelling at night when the cooler air allows you to move farther and faster with a lower risk of heat exhaustion. This simple decision can save your body about three litres of water per day. During the day, minimise activities that make you sweat, as water loss through perspiration is one of the biggest concerns in the desert.
Finding Water Sources
While conserving water and energy is crucial, you will eventually need to find a source of water. Water is rare in the desert, so follow birds, insects, or animal tracks to locate streams or rivers, which are preferable sources due to the constant movement that prevents the spread of harmful bacteria. If you cannot find surface water, try searching for it underground, especially in areas with vegetation, dry streams, or the ground near mountain bases. Look for small spots of wet sand and start digging. If you find wet sand, dig a hole about a foot deep and wide, then wait for water to collect. Use a piece of cloth to absorb the water and transfer it to a container.

Dig for water near vegetation or where the soil is damp
Digging for water in the Australian desert can be a challenging task that requires a combination of knowledge, skill, luck, and persistence. Here are some tips to increase your chances of finding water:
Vegetation and Soil Moisture
Look for areas with vegetation, such as green plants, grasses, or trees, as these can indicate the presence of underground water sources. Vegetation thrives where water is accessible, so their roots can provide valuable clues. Pay attention to the distribution of specific tree species, such as desert oaks, mulga trees, and native figs, as they often coincide with deeper water table patterns and reliable subsurface moisture. Additionally, keep an eye out for plants like bush tomatoes, pigface plants, and salt bushes, which often grow in areas where water can be accessed through traditional digging techniques or shallow wells.
Soil Conditions
Examine the soil for moisture or dampness. Digging in dry, sandy areas is less productive, so focus your efforts where the soil feels damp or clay-like. This indicates a higher likelihood of finding groundwater or accessible water sources. Remember that water tends to collect at the lowest points in the area, so consider digging near the base of sloping rock features or in the early morning when groundwater is closest to the surface.
Digging Techniques
Once you've identified a promising spot, start digging carefully with a shovel or your hands. Keep the hole relatively small to minimize the amount of dirt that falls back into the hole and to make water extraction easier. Dig to a depth of at least one foot below the surface, as this is the typical depth at which water may be found. If you encounter wet sand or moist soil, you may have found a potential water source. Expand the hole to make it wider, approximately one foot in diameter, and then wait a few hours for water to collect.
Water Collection and Purification
If a pool of water begins to form, use a cloth to absorb the water and transfer it to a container. Remember to disinfect and purify the water before drinking. Boiling the water, using iodine tablets, or filtering it through an anti-microbial filter will help remove biological contaminants that can cause health issues.
Safety Precautions
Digging for water in the desert can be exhausting, so it's crucial to prioritize your safety. Make sure to dig during cooler parts of the day, stay hydrated, and take frequent breaks. Wear appropriate clothing that covers your arms and legs to protect yourself from the sun and desert vegetation. Additionally, be cautious of desert wildlife, shifting sand, and unstable terrain. Always let someone know where you're going and when you plan to return.

Observe natural indicators like mangroves, fig trees, and pigface plants
Australia's deserts are some of the driest places on Earth, but they are home to numerous plant species that can serve as indicators of water sources. Observing these natural indicators can be a matter of survival when exploring the Australian wilderness.
Native fig trees, for example, often indicate permanent underground water sources. The presence of fig trees can be a reliable sign that water is accessible, even if it requires digging to reach it. Similarly, the distribution of mulga trees frequently indicates areas of reliable subsurface moisture.
In coastal regions, observing the growth patterns of mangroves can be extremely useful. Mangroves often indicate fresh water seepage points along coastlines. They reveal where freshwater meets the sea, providing an essential clue for those seeking drinking water.
Another plant to look out for is the pigface plant. The presence of these plants often indicates that fresh water can be accessed through shallow wells. This knowledge can be invaluable when navigating arid regions, as it can direct explorers to sources of water that may be easier to reach than deeper wells.
In addition to these species, other indicators can provide clues about water availability. For example, the presence of bush tomatoes often coincides with areas where water can be accessed through traditional digging techniques. Furthermore, the distribution of salt bush can reveal the boundaries between saline and freshwater resources, helping explorers discern whether water sources are likely to be potable.
When searching for water in the Australian desert, it is crucial to pay attention to the health and vigour of the vegetation. The greenest, healthiest trees in an area often indicate reliable water sources. Their leaves tend to be larger and more succulent, and their bark may appear darker or more moist than that of surrounding trees.

Collect water from eucalyptus roots, cactus fruit, or morning dew
Finding water in the Australian desert requires a thorough understanding of natural systems, careful observation of environmental indicators, and the practical application of proven techniques. Here are some methods for collecting water from eucalyptus roots, cactus fruit, or morning dew:
Collecting Water from Eucalyptus Roots
Eucalyptus trees are a good indicator of water sources. During their first growing season or two, young eucalyptus trees are entirely dependent on irrigation. If the soil is only slightly damp, the fine root hairs will rise to the surface in search of water instead of growing downwards. These roots can grow at a rate of 1 cm per day, so if they don't receive enough water during this phase, they will die. Once established, eucalyptus trees are very drought-tolerant. However, inadequate watering can train the roots to grow incorrectly, making the plant unstable and more prone to blowing over in windy weather. Therefore, observing the growth patterns of eucalyptus roots can provide valuable information about the presence of water in the Australian desert.
Collecting Water from Cactus Fruit
Cactus fruit, such as the berries on a cholla cactus, can be a source of water in the desert. To extract water from the cactus, cut off the top and skin down the sides, removing the spines. The cactus meat can be sticky, similar to a cucumber, and you should avoid the central core as it is stringy. Wrap the meat in a cloth, squeeze it, and then wring it out to obtain the water.
Collecting Morning Dew
Morning dew is another source of water that should not be overlooked. To collect dew, use a thin rag or handkerchief, preferably white, and venture out early in the morning before sunrise. Feel the grass with your hands to find dew, and if present, wipe the blades of grass and leaves with your rag until it is soaked. Then, wring out the rag into a bowl. If you wish to save the dew for later use, you will need to preserve it with alcohol.

Frequently asked questions
The Australian desert is a hot and dry place, and dehydration can set in quickly. Make sure to find shelter and shade during the hottest parts of the day and keep your skin out of the sun. Conserve your energy and slow down your search for water.
Look for wildlife or dense, green vegetation. You can also look for shaded canyons or valleys where rainfall may accumulate. Keep an eye out for mallee eucalypts, or eucalypts that grow with multiple stems emerging outward from the same underground tuber, as they are a traditional source of water. Other trees that indicate water is present include desert kurrajong, needle-bush, desert oak, and water bush.
If you are in an area used for cattle, you may see artificial water collection points at the base of gently sloping ground. Carry binoculars to help you spot these from a distance. When the sun is low in the sky, look for the glare of a reflection on the ground, which may be a body of water. If you can't find surface water, try digging for it. Dry streams, the ground around the base of mountains, or anywhere with vegetation are good places to start digging.
Turn over half-buried stones just before dawn and dew may form on their surfaces. Check for scorpions and other animals before reaching underneath. You can also collect water from eucalyptus roots, although this can be difficult.
Cactus fruit is safe to eat and can provide enough moisture to supplement other sources of hydration. Collect the fruit carefully, then roast them in a fire for 30-60 seconds to burn off the spines and hairs. You can also eat prickly pear cactus pads, but they are best gathered young in the spring and then cooked.
