In Sydney there are lavish fireworks displays every New Year's Eve. There's a warmup round for the little kids around 9 pm, and then the grand finale at midnight. Usually the Sydney Harbour Bridge has a starring role in the display, and the number, in tonnes, of exploded pyrotechnics is mind-boggling.
2000 was a big year for fireworks, with the Olympics opening and closing ceremonies and various millenium-related events.
