SYDNEY: Global terror attacks have cast a pall over 2016 but Australia was Saturday set to defy the threats and ring in the New Year with bumper crowds gathering to watch a firework extravaganza on Sydney's glittering harbour.
2016 has seen repeated bloodshed, most recently a deadly truck attack at a Berlin Christmas market, a similar incident on Bastille Day in France that killed 86, and atrocities in Turkey and the Middle East.
Some 1.5 million people are packing Australia's biggest city to watch the midnight fireworks, a larger-than-usual crowd due to the weekend timing and warm weather, as the New South Wales state premier urged "business as usual".
"My encouragement to everyone is to enjoy New Year's Eve... in the knowledge that police are doing everything they can to keep us safe," Premier Mike Baird said.
