Australia is a developed country

Australia is the oldest,[16] flattest,[17] and driest inhabited continent,[18][19] with the least fertile soils.[20][21] It has a landmass of 7,617,930 square kilometres (2,941,300 sq mi).[22] A megadiverse country, its size gives it a wide variety of landscapes and climates,

with deserts in the centre, tropical rainforests in the north-east, and mountain ranges in the south-east. Australia generates its income from various sources, including mining-related exports, telecommunications, banking, manufacturing, and international education.[23][24][25]

Australia is a developed country, with the world’s thirteenth-largest economy and tenth-highest per capita income.[26] It is considered a regional power and has the world’s thirteenth-highest military expenditure.[27] Immigrants account for 30% of the population,[28] the

highest proportion in any country with a population over 10 million.[29] The country ranks highly in measures of health, education, economic freedom, and civil liberties.[30] Australia is a member of the United Nations, G20, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development (OECD), World Trade Organization, Asia-Pacific Economic Cooperation, Pacific Islands Forum, and the ASEAN Plus Six.
