A good survival tip I saw ages ago on a Malcom Douglas outback show said that you should always have steel wool in your car if you're driving in the outback. You can use it to easily start a fire by connecting some jumper leads (which you should have too if you're going out bush) to a piece of steel wool set in your campfire place and to the car battery. It produces a similar effect and gets a camp fire going easily.

Oh, sure, you could have matches, a lighter etc. in your car, but where's the fun in that? Plus the steel wool is also handy for cleaning battery contacts and many other things.
