Which Sydney landmark is used as the central platform for the city's famous New Year's Eve fireworks?

Sydney Harbour Bridge is the central platform for Sydney's famous New Year's Eve fireworks.

The bridge's arch and roadway provide a highly visible structure from which fireworks are launched during Sydney's annual celebration. The event also uses barges and other locations around Sydney Harbour, creating a display that frames the harbour and nearby landmarks.

Sydney's New Year's Eve celebration is organized by the City of Sydney and includes a midnight fireworks show as well as earlier family-oriented events. The harbour setting allows spectators on the foreshore, boats, and designated vantage points to view the display from different angles.

The Sydney Opera House is a prominent part of the usual picture and is often illuminated or used as a viewing landmark, but it is not the answer to the question about the main launch structure. The bridge's distinctive arch is the feature most closely associated with the fireworks themselves.
