Concept map of Australia: clear summary and structured scheme of territory, climate, population, and economy. The land is divided into three areas: deserts in the center-west, the Great Artesian Basin in the center-east, and mountains in the east. Climate ranges from tropical in the north to desert in the center and Mediterranean in the south. Population (about 26 million) is concentrated on the coasts. The economy is highly developed: agriculture, farming, mineral resources, and services.
