Australia Day is a public holiday held on 26 January every year in Australia. It is celebrated to remember the day that the First Fleet landed in Australia. On 26 January 1788 British people landed at Sydney Cove and began a British convict settlement.

On 13 May 1787, 11 ships were sent from Great Britain to Australia. The ships carried mostly prisoners to Australia where many were going to be living the rest of their lives. 

Some people do not believe that Australia Day should be celebrated on this date. For example, some indigenous Australians call the date Invasion Day or Survival Day because it was the day that their native land was invaded.

Walkabout is a rite of passage in Australian Aboriginal society, during which males undergo a journey during adolescence, typically ages 10 to 16, and live in the wilderness for a period as long as six months to make the spiritual and traditional transition into manhood. The term has been superseded with "temporary mobility" because its original name has sometimes been used as a derogatory term in Australian culture, demeaning its spiritual significance.

"Temporary mobility" is a nomadic lifestyle that does not establish a permanent residence and includes a significant amount of movement for religious observance. Young Indigenous adults have the highest mobility rate of all age groups in Australia; males make up the majority. Youth is the time of the traditional "walkabout" rite of passage, which marks the transition into adulthood.
