(English correction by Liam)
Lack of experience in Australian wilderness was the reason then I started my first adventure in four wheel drive. We had seven cars 4WD in our convoy (Toyota Landcruiser and Nissan Patrol). Helping each other we were crossing the longest isolated trail in the world - Canning Stock Route. It is almost 2000km waste area, on the way waiting to be crossed more than 700 sand dunes, located on the four deserts of 
Western Australia - Great and Little Sandy Desert, Gibson and Tanami Desert. There is no guaranteed sources of water or food, it is not possible to count on quick help. You have to be self-sufficient, several people lost their lives on this trail. Nowdays is a bit easier thanks to the availability of technologies such GPS and satellite phone, but electronics can fail and basic navigation, the ability to find water or fix a car is essential.
Because our cars were broke down, mostly shock absorbers, they have failed in all vehicles. One car broke down so much that had to evacuate one of the side road - just 800 km. With escort of our second vehicle finally get to the civilization. The second car received our spare parts ordered earlier by satellite phone and went back to us.
But I couldn't stay inactivity for four days, so I started walk and indicated all turns I took by easly visible pink fabric. The team after fix the cars caught me (72 km) and then we continued the journey together. We had ordered as well the fuel depot in the middle of nowhere, and the 200-litre barrels were waiting for us. Once rocky phyton visited our camp, other time during crowling in the cave I have seen deadly redback spider. A bit of challenge was during the salty creek crossing, that wasn't so simple.
How come there are rivers in the desert? If you look at the map of Australia you will find that a lot of rivers 
have two beginnings, or ends. Explorer Charles Sturt during his nineteenth-century expedition was carring the boat in search of an inland sea. The rivers get a water resulting from the rain hundreds kilometers away, and they are not ending in the mouth of any sea or lake. They are just absorbed by hungry soil and dry air. During this two week ride I have seen amazing nature, because the desert is changed with each sand dune, has its color of sand, bushes, flowers and salty lakes. We visited on the way the aboryginal settlement where we purchased kangaroo tail and made a soup and camel meat from which we make steaks. During each evening we made a camp fire and were keeping an interesting conversations. This trip was for me a good lesson.
