Melbourne treated to unexpected fireworks display CITY-dwellers were treated to a spectacular display of colourful fireworks, although many were left wondering what exactly the city was celebrating. The event on Saturday night sent local twitter users into overdrive, with some speculating the display was to celebrate Beyonce's final Melbourne concert or even the American holiday, Halloween. The fireworks display was actually a part of the Diwali Indian Festival of Light 2013, held in Federation Square. The event celebrated Indian culture, including Henna painting, traditional cuisine and Bollywood dance workshops topped off with fireworks across the city skyline.
