Revellers welcomed 2019 with fireworks displays and festivities as a celebratory wave swept westward across the globe from Asia to Europe and the Americas at the conclusion of a tumultuous year.
Monday's celebrations kicked off with Sydney hosting its biggest-ever pyrotechnics display and lighting up its harbour-front skyline for a full 12 minutes.
More than 1.5 million spectators gathered to enjoy the spectacle that also featured a ceremony to celebrate Australia's indigenous culture.
