Sydney's New Year's Eve fireworks famously welcomed the new millennium at the Sydney Harbour Bridge in 2000.
The celebration occurred as the calendar changed from December 31, 1999, to January 1, 2000. Sydney was among the first major cities to reach the new year, so its harbor fireworks became a globally watched symbol of the millennium transition.
The display centered on Sydney Harbour, with fireworks arranged around the Harbour Bridge, the Opera House, and nearby waters. A major visual moment was a large “Eternity” effect on the bridge, referring to the handwritten word associated with Australian evangelist Arthur Stace.
People sometimes describe the event simply as the “1999 fireworks,” because the show began on New Year's Eve in 1999. The year being welcomed, however, was 2000, and the date after midnight was January 1, 2000.
