"Civilization did not begin in Australia until the last quarter of the eighteenth century. The reason lies partly in the environment and way of life of the people inhabiting the continent before the coming of the European, and partly in the internal history of those Hindu, Chinese, and Muslim civilizations which colonized and traded in the archipelago of south-east Asia. The early inhabitants of the continent created cultures but not civilizations."
