Sydney will be one of the world's first major cities to celebrate, setting the tone with 20 minutes of pyrotechnics all up, a smoking ceremony, AI-driven projections onto the harbour bridge and illuminated boats on the water.
More than a million people are expected to flock to the harbour foreshore and surrounding vantage points.
