What is the name of the New Year's Eve countdown held at Sydney Harbour?

The New Year's Eve countdown held at Sydney Harbour is called Sydney New Year's Eve.

Sydney New Year's Eve is an annual celebration centered on Sydney Harbour, with the Sydney Harbour Bridge, Sydney Opera House, and surrounding waterways forming its iconic setting. Its headline feature is a large fireworks display at midnight, supported by earlier events such as an evening family fireworks show in many editions.

The harbor setting gives the celebration a distinctive visual identity. Fireworks may be launched from the bridge, barges, and other harbor locations, depending on the year's production plan. Large crowds also watch from public vantage points, ticketed areas, boats, and homes around the water.

Sydney is often mentioned in lists of the first major cities to welcome the new year, but “first” depends on the comparison and on which inhabited places are included. The official event name is more precise than that popular shorthand.
