Introduction

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 has a land area of 7,688,287 km2 (2,968,464 sq mi), making it the sixth-largest country in the world, and is the world's flattest and driest inhabited continent. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, including deserts in the interior and tropical rainforests along the coast.
The ancestors of Aboriginal Australians began arriving from Southeast Asia 50,000 to 65,000 years ago, during the Last Glacial Period. By the time of British settlement, Aboriginal Australians spoke more than 250 distinct languages and had one of the oldest living cultures in the world. Australia's written history commenced with Dutch exploration of most of the coastline in the 17th century. British colonisation began in 1788 with the establishment of the penal colony of New South Wales. By the mid-19th century, most of the continent had been explored by European settlers and five additional self-governing British colonies were established, each gaining responsible government by 1890. The colonies federated in 1901, forming the Commonwealth of Australia. This continued a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942, and culminating in the Australia Act 1986.
Australia is a parliamentary democracy with a constitutional monarchy, and a federation comprising six states and ten territories. Its population of almost 29 million is highly urbanised and heavily concentrated on the eastern seaboard. Canberra is the nation's capital, while its most populous cities are Sydney and Melbourne, each with a population of more than five million. Australia's culture is diverse, and the country has one of the highest foreign-born populations in the world. It has a highly developed economy and one of the highest per capita incomes globally. Its abundant natural resources and well-developed international trade relations are crucial to the country's economy. It ranks highly for quality of life, health, education, economic freedom, civil liberties and political rights.

The Australian Air Corps (AAC) was a temporary formation of the Australian military that existed in the period between the disbandment of the Australian Flying Corps (AFC) of World War I and the establishment of the Royal Australian Air Force (RAAF) in March 1921. Raised in January 1920, the AAC was commanded by Major William Anderson, a former AFC pilot. Many of the AAC's members were also from the AFC and would go on to join the RAAF. Although part of the Australian Army, for most of its existence the AAC was overseen by a board of senior officers that included members of the Royal Australian Navy. (Full article...)
Selected biography -
Sidney Charles Bartholemew "Ben" Gascoigne AO (11 November 1915 – 25 March 2010) was a New Zealand-born optical astronomer and expert in photometry who played a leading role in the design and commissioning of Australia's largest optical telescope, the Anglo-Australian Telescope, which for a time was one of the world's most important astronomical facilities. Born in Napier, New Zealand, Gascoigne trained in Auckland and at the University of Bristol, before moving to Australia during World War II to work at the Commonwealth Solar Observatory at Mount Stromlo in Canberra. He became skillful in the design and manufacture of optical devices such as telescope elements. (Full article...)
