Australia day 
is celebrated annually on January 26th, as that marks the anniversary of the 1788 arrival of the First Fleet of British Ships at New South Wales as well as the raising of the flag of Great Britain at that location. In present-day Australia, however, celebrations focus much less on the arrival of the aforementioned ships, and instead concentrate more on the diverse society and landscape of the nation. Many community and family events are organised, as well as various celebrations welcoming new immigrants. Australia is a relatively young country, as federation occurred just over 100 years ago in 1901, so it was not until 1935 that Australia Day was actually celebrated. Due to the rapid decline of the indigenous population after the arrival of British ships on Australia’s shores, some prefer to call this holiday “Invasion Day” as a way of remembering the many that died from various diseases in the 18th and 19th centuries.
