Sydney New Year's Eve is an annual New Year's Eve fireworks event in Sydney, New South Wales, Australia. The event currently consists of two fireworks shows, with an evening display known as the "Family Fireworks" held at 9:00 p.m. AEDT, and the main "Midnight Fireworks" held at 12:00 a.m. Fireworks are launched from barges in Port Jackson, as well as nearby landmarks such as the Sydney Opera House, and the Sydney Harbour Bridge, which serves as the main focal point of the show via lighting and pyrotechnic effects.

Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays, combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious celebrations, though mismanagement could lead to fireworks accidents.
