“Australia Day, also known as Anniversary Day and Foundation Day, is the official national day of Australia. Celebrated annually on 26 January, the day commemorates the arrival of the First Fleet at Sydney Cove in 1788, the unfurling of the British flag there, and the proclamation of British sovereignty over the eastern seaboard of Australia.”
