Australia has welcomed 2024 in style with wild parties that last long into the night.
More than a million people flocked to viewing points across Sydney Harbor to watch the fireworks display, while others enjoyed themselves in pubs, clubs and parties.
Revelers poured into the streets after the clock struck twelve, rushing to get home or, in some cases, to keep the party going.
The muggy weather caused men to unbutton their shirts and glamorous ladies in summer dresses to ditch their heels and go barefoot.
Couples walked arm in arm while others took to the deck, too exhausted to wade through the endless crowds after a long day of action.

For some, it was a 17-hour wait after queuing from the early morning hours to get a premium spot.
But it was worth it when the clock struck 12 for the families, friends, world travelers and locals alike who enjoyed front-row fireworks, a smoking ceremony, AI-powered projections on the harbor bridge and illuminated boats on the water.
Smaller groups were seen dancing on the pylons of the Harbor Bridge as children looked on in wonder.
By 5pm most of the major viewing points around the waterfront had already reached capacity and by 11.30am the Sydney Opera House was full.

'It's unbelievable that we're here. It feels surreal,” she said.
She had been queuing since 7.30am and described the scene as 'total madness'.
'It's not that easy to find a good place to sit, but the view is incredible.'

Sydney Mayor Clover Moore said the city's New Year's Eve festivities gave the economy a $280 million boost, a 2019 study found.
“They remind the world that Sydney is a global city for tourism, business, culture, technological creativity and most importantly, Sydney is an inclusive and diverse city for all our communities,” she told reporters on Sunday.
Melbourne was treated to a non-stop and vibrant fireworks display alongside a far-reaching laser show that set the city's skyline ablaze from 27 rooftops.
After the noon show, cheers echoed through the city, with hordes of people leaving designated party areas after witnessing the three semi-trailer loads of fireworks.
More than 400,000 people gathered in the city center to ring in the new year, many vying for a spot on the Docklands waterfront.
Rose Stafrace, from Mill Park in Melbourne's northeast, had been venturing into the city for the fireworks for more than 30 years. She thought the 2023 New Year's Eve crowd was bigger than the previous one.
“Every year more and more people come,” Ms Stafrace told AAP.

'I love it when I come here and see different people, different nationalities.
“It gives me the joy of the Melbourne community.”
