MovementThe first people to live in Australia were the Aborigines, but that isnot the main contribution to why the population is as great as it is.When British explorers first discovered Australia, they thought,because it was so wide and open, that it would be a great place toplace some of their convicts due to overflow in their jails. There wasan agreement that this would work if the criminals provided laborfor crops and mines. When Australia first started finding gold in themines, news spread quickly, and people from all over the world, especially from Europe, came to mine,and a gold rush was started. This made the country much more known around the world, and peoplestarted to come in from many Southeast Asian countries as well as European countries. Even today, thevariety of ethnic backgrounds of the people inhabiting Australia is still strong. Very rarely do problemsoccur with ethnic differences. Europe contributed more to Australia than just people. They also brought bad things such as new diseases and good things such as new ideas, such as religion. Christianity was brought by the Europeans, and is now the most popular religion in Australia. The inventions of the car and truck were very important for transportation in Australia. Because most cities are very spread apart, the ability to transport crops and other goods as quickly as we can now has become vital in keeping supplies fresh. To transport products to other countries, cargo ships and airplanes have been the mean of transportation for several decades.The concept of telephones has also helped some cities become less isolated, because they dont have tomake long journeys to communicate with important cities such as the capitol. Australia has continued togrow as a country over the years due to inventions, exports, and tourism income.
