Commonwealth of Australia. It is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands.

History

The first human habitation is traced to Aboriginal peoples who arrived via ancient land bridges and sea crossings from Southeast Asia. European exploration began in the 17th century, notably by Dutch navigator Willem Janszoon. In 1770, James Cook claimed the east coast for Great Britain. The first British settlement was established at Port Jackson in 1788, beginning the era of colonial administration and penal transportation. The 19th century saw the expansion of colonies, conflicts such as the Eureka Rebellion, and the devastating impacts of frontier wars on Indigenous populations. Federation of the six colonies was achieved on 1 January 1901, following the passage of the Commonwealth of Australia Constitution Act by the Parliament of the United Kingdom. The new nation participated in both World War I, including the Gallipoli Campaign, and World War II, notably during the Battle of the Coral Sea. The post-war period saw massive immigration from Europe, the abolition of the White Australia policy, and significant legal milestones like the Mabo decision on native title.

The government is based on the Australian Constitution, with power divided between the federal Parliament and the states.
