Etymology

The name Australia derives from the Latin Terra Australis Incognita (“unknown southern land”), a name used for a hypothetical southern continent since antiquity.[Name_of_Australia]

When Dutch explorers first mapped the continent in the 17th century, they called it New Holland. The term Australia was popularised by the English navigator Matthew Flinders, who circumnavigated the continent in 1803; his 1814 publication used the name, and it gradually superseded “New Holland”.[Name_of_Australia]

In 1817 Governor‑General Lachlan Macquarie recommended the name “Australia” to replace “New Holland”. The British Admiralty adopted it in 1824, and the British Parliament used it in legislation in 1828.[Name_of_Australia]

Colloquial names for Australia include “Oz”, “Straya” and “Down Under”.[Colloquial_names_for_Australia]

History

Indigenous prehistory

Main articles: [Prehistory_of_Australia] and [Indigenous_Australians]

Aboriginal Australians are the descendants of the first humans to arrive on the continent, with archaeological evidence dating their presence to between 50,000 and 65,000 years ago.[Prehistory_of_Australia]

At the time of European contact, Aboriginal peoples spoke over 250 distinct languages and maintained one of the world’s oldest continuous cultures.[Indigenous_Australians]

The Dreaming (or Dreamtime) is a central spiritual framework that encodes creation stories, law, and cultural practices through oral tradition, song, dance, and painting.[The_Dreaming]

European exploration and colonisation

Main articles: [European_maritime_exploration_of_Australia], [European_land_exploration_of_Australia], and [History_of_Australia_(1788%E2%80%931850)]

The first recorded European landing was by the Dutch ship Duyfken in 1606, commanded by Willem Janszoon.[Duyfken]

In 1642 Abel Tasman explored the west coast of Tasmania and named the region “Van Diemen’s Land”. Subsequent Dutch voyages mapped much of Australia’s northern, western and southern coasts, calling the landmass New Holland.[Abel_Tasman]

In 1770 British Captain James Cook claimed the east coast for Great Britain, naming it New South Wales.[James_Cook]

The First Fleet, under Arthur Phillip, arrived in 1788 to establish a penal colony at Sydney Cove, an event later commemorated as Australia Day.[First_Fleet]

Most early settlers were British convicts, who were assigned as labourers or servants. Over time, many became free citizens after completing their sentences.[Convicts_in_Australia]

Frontier conflicts between settlers and Indigenous peoples, often termed the Australian frontier wars, resulted in significant loss of life on both sides and have been described by some scholars as genocide.[Australian_frontier_wars]

Colonial expansion

Main articles: [History_of_Australia_(1788%E2%80%931900)] and [History_of_Australia_(1901%E2%80%931945)]

Between 1803 and 1850 additional colonies were established: Tasmania (1825), South Australia (1836), Victoria (1851), and Queensland (1859). Some were founded as “free” colonies that never accepted transported convicts.[Colonial_expansion]

The discovery of gold in the 1850s triggered rushes that brought large numbers of immigrants from Europe, North America and China, dramatically increasing the population and economic activity.[Australian_gold_rushes]

In the late 19th century, the colonies moved toward responsible government, establishing their own parliaments and gradually gaining control over local affairs.[Responsible_government]

Federation to the World Wars

On 1 January 1901, the six colonies federated to form the Commonwealth of Australia, adopting a constitution that established a federal parliamentary system.[Federation_of_Australia]

Australia participated in the First World War, losing over 60,000 soldiers, an experience that forged a distinct national identity, especially through the ANZAC campaign at Gallipoli.[First_World_War]

During the Second World War, Australia shifted from a British to an American security umbrella after the fall of Singapore and the bombing of Darwin.[Second_World_War]

Since 1951 Australia has been a formal ally of the United States under the ANZUS treaty, and has participated in various multinational conflicts and peace‑keeping missions.[ANZUS]

Post‑war and contemporary era

The post‑war period saw a massive immigration program that relaxed the historic “White Australia” policy, leading to a multicultural society.[Post_war_immigration_to_Australia]

The 1967 referendum allowed the federal government to include Indigenous Australians in the census and to legislate for them, a watershed moment in Indigenous rights.[1967_Australian_referendum]

The 1992 Mabo decision by the High Court rejected the legal doctrine of terra nullius, recognising native title for the first time.[Mabo_v_Queensland_(No_2)]
