Australia's National Day is celebrated on January 26. It has its beginnings in the anniversary of the arrival of the First Fleet of 11 convict ships from Great Britain, originally called Landing Day or Foundation Day.
Captain Arthur Phillip, the first governor of New South Wales, raised the Union Jack flag at Sydney Cove in 1788, which commemorated the British occupation of the continent's eastern half claimed by Captain James Cook on August 22, 1770.
January 26 marks Australia's national holiday, Australia Day.
Australia Day celebrates the establishment of the first settlement in Port Jackson (which is now Sydney Harbour), in 1788.
What's known as the "First Fleet", consisted of 11 ships that set sail from Great Britain and landed on this day at the Port. By 1808, January 26 was celebrated as “First Landing Day” or “Foundation Day”.
In 1818, the Governor of Australia gave all government employees a day off, and in the years that followed, bank employees, and other employees, were also given a holiday day.
