After a year characterised by cost of living pressures, more Australians say they hope to welcome 2024 minus the hefty price tag, with one-in-three taking advantage of free sites to view the festivities.
Sydney will be one of the world's first major cities to celebrate, setting the tone with 20 minutes of pyrotechnics, 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.
City of Sydney fireworks director Fortunato Foti said onlookers could expect something a little different, with displays featuring bright white, peach, lime, silver, gold, violet, yellow, burnt orange, pink and blue fireworks.

More police than ever before would be out across Sydney for one of the city's biggest celebrations, NSW Assistant Commissioner Anthony Cooke said.

"Look out for your mates and ensure everyone gets home safely," Mr Cooke said.
"Nobody wants to see anybody begin the New Year in the back of a police truck."
