We did it: the clock’s ticked over to 2018 and Australia has celebrated in colourful, explosive style.
Sydney did what it does best with a dazzling pyrotechnics display in front of the estimated crowd of one million, who watched from vantage points around the harbour.
A massive cheer went up as the first thunderous blast of a 12-minute display rattled the harbour.
Some eight tonnes of fireworks produced 100,000 individual pyrotechnic effects as the sky exploded in a riot of colour and light, with the centrepiece a rainbow tribute to the nation's historic same sex marriage vote and the upcoming 40th anniversary of Mardi Gras.
Among the crowds were same-sex couples, still basking in the recent victory of the 'yes' vote.
Alex Parkes, who watched the fireworks with his partner, said the tribute had made him feel part of a greater community.
"I think it's a beautiful reminder of the progress achieved this year and exactly how far we've come," he told AAP.
