Final answer:
Australia is a large island continent with unique species of plants and animals. Its population is concentrated in urban areas, and the economy relies on the export of food and raw materials.
Step-by-step explanation:
Australia is a large island continent that is home to unique species of plants and animals. It was first colonized by the British who established prison colonies for convicts from Great Britain. The continent is relatively flat with low elevation highlands along its eastern coast and a vast interior outback that lacks precipitation and consists of numerous deserts.
Australia's population is concentrated mostly in urban areas, with about 90 percent of the population living in cities located in coastal areas. Sydney is the largest city in Australia and is often referred to as the New York of Australia. Other major cities include Melbourne, Perth, Adelaide, and Brisbane.
Australia's economy relies on the export of food and raw materials. While it was a former British colony, Japan is now Australia's biggest trading partner. The continent is geographically closer to the Asian economic community than to the European Union.
