1.5m line Sydney harbour
An estimated 1.5m people lined Sydney harbour for the annual New Year firework spectacular night, according to the organisers.
This year, seven tonnes of fireworks were ignited on the Harbour Bridge and at different locations around the city including, for the first time in a decade, on the sails of the Sydney Opera House, to create a 12-minute long show, coordinated with lighting and music, the city council said.
More than 1,000 fireworks were set off from the roof of the World Heritage listed Opera House, having been specially designed not to damage the building which celebrated its 40th anniversary in 2013.
Organisers estimated the fireworks display, costing AU$ 6.8m, would be watched by as many as a billion people around the world.
The show was started by creative designer, artist and musician Reg Mombassa and the Lord Mayor of Sydney Clover Moore.
