It marks the anniversary of the 1788 arrival of the First Fleet of British ships at Port Jackson, New South Wales and the raising of the Flag of Great Britain at Sydney Cove by Governor Arthur Phillip.

Australia Day is for all Australians, no matter where our personal stories began. Most of Australians will chill by the pool with friends and family cooking some meat on a Barbie.
