The world's eight billion people have begun ushering in 2023 and bidding farewell to a turbulent 12 months marked by war in Europe, stinging price rises, Lionel Messi's World Cup glory and the deaths of Queen Elizabeth, Pele and former pope Benedict.
Many will be looking to cut loose this New Year's Eve after a few pandemic-dampened years, setting aside pinched budgets and a virus that is increasingly forgotten but not gone.
Sydney was among the first major cities to ring in 2023, restaking its claim as the "New Year's Eve capital of the world" after two years of lockdowns and coronavirus-muted festivities.
Australia's borders have reopened and throngs of revelers gathered along Sydney's sparkling harbor to watch 100,000 pyrotechnics light up the southern sky.
A crowd that had been projected to hit more than one million watched as a spectacular 12-minute display showered the waterway and illuminated the Sydney Harbour Bridge.
"It's been a fairly good year for us; getting past Covid of course is great," David Hugh-Paterson told AFP as he waited in a growing crowd near the Sydney Opera House.
"Looking forward to the future as well," the 52-year-old said.
Sydney authorities expected almost half a billion more people would see the festivities online or on television.
"If we can bring everyone together in celebration and looking to the year ahead with renewed optimism and joy, then we'll see that as a job well done," fireworks organizer Fortunato Foti had said.
For some, 2022 was a year of Wordles, the Great Resignation, a new Taylor Swift album, an Oscar slap and billionaire meltdowns.
It also saw the deaths of Queen Elizabeth II, Brazilian football icon Pele, Mikhail Gorbachev, Jiang Zemin, and Shinzo Abe. Former pope Benedict XVI also died on New Year's Eve.
The global population surpassed the historic milestone of eight billion people in November.
But 2022 is most likely to be remembered for armed conflict returning to Europe -- a continent that was the crucible of two world wars.
