Explorer Matthew Flinders popularised the name Australia
The name Australia is derived from the Latin Terra Australis Incognita ('unknown southern land'), a name used for a hypothetical continent in the Southern Hemisphere since ancient times. The name Australia was popularised by the explorer Matthew Flinders, who was the first to circumnavigate the continent in 1803. He used the name 'Australia' to describe the continent on a hand-drawn map in 1804.
Flinders is revered in Australia but remains relatively unknown in his native England. He was born in Lincolnshire in 1774 and joined the British Royal Navy in 1789 at the age of 15. Flinders sailed as a midshipman on William Bligh's second breadfruit voyage to Tahiti in 1792, where he developed a passion for cartography. He was also accompanied by a ship's cat named Trim, who was born on board the Reliance in 1799.
When Flinders returned to Britain in 1807, he published his charts and wrote to Sir Joseph Banks, President of the Royal Society, to argue for a voyage to chart the remaining coasts of Australia. Banks, a proponent of imperial expansion, agreed, and the Flinders expedition was one of the first attempts to open up lands for colonial expansion. On board were botanists and scientists, who studied the natural resources and native flora and fauna to determine the land's suitability for farming and immigration.
Flinders sailed on the Investigator, a ship in poor repair that leaked constantly. Despite the odds, he successfully circumnavigated the Australian coastline, charting much previously unknown territory. The maps he produced were the first to accurately depict Australia as we know it today, and he proved that Australia was a single continent.
When the map and book describing his journey were published in 1814, the name 'Terra Australis' was used instead of 'Australia' at the insistence of his patron, Joseph Banks, who argued that 'Terra Australis' was the name most familiar to the public. However, Flinders stated that he still preferred the name 'Australia'.
Governor Lachlan Macquarie of New South Wales became aware of Flinders' preference for the name 'Australia' and used it in his dispatches to England. On 12 December 1817, Macquarie recommended to the Colonial Office that the name be officially adopted, and in 1824, the British Admiralty agreed that the continent should be officially known as Australia.

Terra Australis, New South Wales and New Holland were original names
The name Australia is derived from the Latin Terra Australis Incognita, which translates to 'unknown southern land'. This name was used for a hypothetical continent in the Southern Hemisphere as early as the 5th century. The continent's existence was hypothesised based on the idea that the land in the Northern Hemisphere should be balanced by land in the Southern Hemisphere. The name Terra Australis was also used interchangeably with Australia by explorer Matthew Flinders, who circumnavigated the continent in 1803 and published a book about his voyage in 1814.
The name Australia was popularised by Flinders, who pushed for it to be formally adopted as early as 1804. In his 1814 book, Flinders stated that there was no probability of finding any significant land mass anywhere more south than Australia, and so the name Terra Australis was most suitable. The name Australia was also used in an astronomical treatise published in 1545, referring to the imagined southern land mass.
Before the name Australia was popularised, the continent had several other names. When the Dutch began mapping Australia in the 17th century, they called it New Holland. The name New Holland was first applied to Australia in 1644 by the Dutch seafarer Abel Tasman. The term New Holland was often used to refer to the western portion of the continent that had not yet been annexed to New South Wales.
The name New South Wales was given by Lieutenant James Cook, who claimed the eastern portion of the Australian continent for the British Crown in 1770. The British government established a settlement in Sydney in 1788, solidifying its claim to the eastern part of Australia, which became officially known as New South Wales.
In addition to these names, there were also various names used by the Indigenous peoples who lived in Australia for thousands of years before the arrival of Europeans. These names varied between different language groups and regions, reflecting their deep spiritual connection to the land.

The country is officially called the Commonwealth of Australia
The country of Australia has had many names throughout history. The continent was called "New Holland" by Dutch navigators who charted its coasts in the 17th century. The name "Australia" was popularised by the explorer Matthew Flinders, who circumnavigated the continent in 1803 and used the name on a hand-drawn map in 1804. The name is derived from the Latin "australis", meaning "southern".
In December 1817, New South Wales Governor Lachlan Macquarie officially recommended the name Australia to replace New Holland. The British Admiralty adopted the name in 1824, and the British Parliament used it in legislation in 1828.

Six colonies joined to create the Commonwealth in 1901
The country of Australia was formed in 1901 when six colonies joined to create the Commonwealth of Australia. The name Australia is derived from the Latin Terra Australis Incognita, which means 'unknown southern land'. This name had been used for a hypothetical continent in the Southern Hemisphere since ancient times.
The six colonies that came together to form the Commonwealth of Australia were New South Wales, Queensland, Victoria, South Australia, Western Australia, and Tasmania. These colonies had been established by the British as penal settlements in the late 18th and early 19th centuries. At the time of federation in 1901, the colonies were already highly autonomous, and the move to unite them was driven by a desire for more effective governance and a stronger national identity.
The process of federation was not without its challenges. It took a decade of planning, consultation, and voting to achieve. One of the key issues was the question of immigration and the restriction of non-white immigrants, particularly Asians, who were seen as a threat to Australia's majority British culture and living standards. This policy, known as the White Australia policy, was a significant point of contention and was eventually extended to exclude Aboriginal people from the franchise unless they already had the vote in a state jurisdiction.
The Commonwealth of Australia Constitution Act 1900 (UK) formalised the name "Commonwealth of Australia" for the new federation of the six former colonies. The Commonwealth of Australia was proclaimed by the Governor-General, Lord Hopetoun, on 1 January 1901, and Edmund Barton was sworn in as Australia's first prime minister. The new constitution established a federal government with defined powers, including external affairs, defence, immigration, taxation, race, and customs and excise.
The formation of the Commonwealth of Australia was a significant moment in the country's history, marking the beginning of Australia as a unified nation with a federal system of government.
