Universal Geography contains the following;

- "For such an expedition, men of science and courage ought to be selected. They ought to be provided with all sorts of implements and stores, and with different animals, from the powers and instincts of which they may derive assistance. They should have oxen from Buenos Aires, or from the English settlements, mules from Senegal, and dromedaries from Africa or Arabia. The oxen would traverse the woods and the thickets; the mules would walk securely among rugged rocks and hilly countries; the dromedaries would cross the sandy deserts. Thus the expedition would be prepared for any kind of territory that the interior might present. Dogs also should be taken to raise game, and to discover springs of water; and it has even been proposed to take pigs, for the sake of finding out esculent roots in the soil. When no kangaroos and game are to be found the party would subsist on the flesh of their own flocks. They should be provided with a balloon for spying at a distance any serious obstacle to their progress in particular directions, and for extending the range of observations which the eye would take of such level lands as are too wide to allow any heights beyond them to come within the compass of their view."

. Some traditional food plants harvested by Aboriginal people in these areas are seriously affected by camel browsing. While having soft-padded feet makes soil erosion less likely, feral camels do have a noticeable impact on salt lake ecosystems, foul waterholes and destabilise dune crests, which contributes to erosion.
Effect on infrastructure
The effects on built infrastructure may be severe, as camels may sometimes destroy taps, pumps and even toilets as a means to obtain water, particularly in times of severe drought. They also damage stock fences and cattle watering points. These effects are felt particularly in
