Commonwealth of Australia

Australia officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the world's sixth-largest country by total area. Neighbouring countries include Indonesia, East Timor and Papua New Guinea to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east.

For at least 40,000 years before the first British settlement in the late 18th century, Australia was inhabited by indigenous Australians, who spoke languages grouped into roughly 250 language groups. After the European discovery of the continent by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and initially settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing Crown Colonies were established.

On 1 January 1901, the six colonies federated, forming the Commonwealth of Australia. Since Federation, Australia has maintained a stable liberal democratic political system that functions as a federal parliamentary democracy and constitutional monarchy. The federation comprises six states and several territories. The population of 23.1 million is highly urbanised and heavily concentrated in the eastern states.

Australia is a developed country and one of the wealthiest in the world, with the world's 12th-largest economy. In 2012 Australia had the world's fifth-highest per capita income, Australia's military expenditure is the world's 13th-largest. With the second-highest human development index globally, Australia ranks highly in many international comparisons of national performance, such as quality of life, health, education, economic freedom, and the protection of civil liberties and political rights. 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, and the Pacific Islands Forum.

Australia Currency

The standard $1 coin design, along with the 50, 20, 10 and 5 cent coin designs, was created by the Queen’s official jeweller, Stuart Devlin.
The $1 coin depicts five kangaroos. The $2 coin depicts an Aboriginal tribal elder set against a background of the Southern Cross and native grass trees. The 50 cent coin features Australia’s coat of arms: the six state badges on a central shield supported by a kangaroo and an emu.
The 20 cent coin carries a platypus, (soon to be replaced by cricket legend Donald Bradman); the 10 cent coin features a male lyrebird dancing; and the 5 cent coin depicts an echidna.
