What New Year's Eve fireworks tradition is Sydney Harbour especially famous for?

Sydney is especially famous for New Year's Eve fireworks over Sydney Harbour Bridge.

Sydney's celebration uses the harbour as a huge natural stage, with fireworks launched from the Harbour Bridge, barges, and other locations around the water. The Sydney Opera House is a prominent part of the skyline, but the bridge is the central landmark named in descriptions of the main display.

The event normally includes an earlier family fireworks show and a larger midnight display. The timing allows television audiences around the world to watch Sydney enter the new year while other time zones are still on December 31. Boat vantage points and foreshore viewing areas are especially popular.

A frequent oversimplification is to say that every firework comes from the bridge. The production uses multiple launch positions across the harbour, so the bridge is an icon of the display rather than its only platform. Weather, safety, and crowd controls can affect each year's arrangements.
