Australia's famous harbour city brought in the New Year on a balmy summer night with a US$6.9 million display curated by pop icon Kylie Minogue, who pressed the button to start the pyrotechnics.
To the roars of the crowds, the sky erupted in light at midnight as fireworks shot up from barges and jet skis in the harbour and cascaded from the Harbour Bridge and burst and glimmered overhead.
"This is really putting Australia on the map in terms of welcoming people to the New Year," Sydney Lord Mayor Clover Moore said.
Officials were expecting up to 1.5 million people to gather in the city and crowds jammed all vantage points along the waterfront to watch the seven tonnes of fireworks ignite the sky.
"We just wanted to see the fireworks," said 19-year-old Silvia Hondt, from Germany, as she walked with friends along the foreshore at Circular Quay.
