I would like to drive to the Devil's Marbles, Alice Springs and Uluru in a 4 wheel drive. You could go by bus, plane, car or bike.
The desert is a long way from Sydney. it is very dangerous of you don't bring the right equipment. To survive safely in the desert, you need food, water, good reliable transport, a first aid kit, clothing for protection from sun and wind, a map and compass.

Aboriginal people don't like tourists walking on their rock.
