Australians have bid farewell to 2024, ringing in the new year with one "world-famous" fireworks display and many others not so famous.
More than a million people rushed to the shores of the Sydney Harbour and hundreds of thousands more to the banks of the Yarra River in Melbourne to watch the midnight displays.
Those who snagged a harbour view earned a stunning front-row display as fireworks dazzled the harbour from both the east and west sides of the famous Sydney Harbour Bridge for the first time.

As a kid Meg Brown would watch in awe from her English home at TV coverage of Sydney's fireworks.

"It is a bit of a bucket list thing for me," Ms Brown told AAP.
"At home the Sydney fireworks is always all over the news, it is one of the first places that brings in the New Year."
David from Argentina was another lucky spectator, snagging a spot at The Rocks.
Attending the fireworks show for the first time after arriving in Australia in June, he and his friends were excited to see what all the fuss is about.
“We’d heard about it so we thought we'd come out,” he said.
“But I’m not partying too hard tonight, I have to work in the morning.”

For Domenic Adami, it was the first time in a few years he'd ventured to the city for New Year's Eve festivities.
But he and his friends arrived early to snag a spot near the Yarra where they set up a picnic while settling in for the midnight show.
"I heard, this year, they're going to be bigger than Sydney, but usually they're pretty good," Mr Adami told AAP.
"Even when I sit and watch it at home or from somewhere else on TV, it looks amazing.
"Each year has just gotten better and better, and this year seems like it's going to be the best."
While Sydney's displays may be the highlight, there's no shortage of fireworks to usher in 2025 across the rest of the nation.
