The ancestors of the first aborigines may have come from Southeast Asia to what is now Australia some 50,000 years ago. For thousands of years, the aborigines lived a primitive, peaceful, and nomadic life, undisturbed by outsiders.
Until British settlement began late in the 18th century, Australia remained inhabited only by the aborigines. However, as early as the second century A.D., some ancient map makers were indicating the probable existence of a large, unknown continent south of Asia. The actual discovery of Australia followed the expansion of Portuguese, Dutch, and Spanish trade into Asian waters.
