Anthony Albanese has won the Australian election and will become the country's 31st Prime Minister.
Scott Morrison, who has since resigned as leader of the Liberal party, called Albanese to concede defeat on Saturday night.
Albanese said he wanted to bring Australians together.
"I want to unite the country," he said at his Labor party's celebrations in Sydney. "I think people want to come together, look for our common interest, look towards that sense of common purpose. I think people have had enough division, what they want is to come together as a nation and I intend to lead that."
Albanese said in his victory speech that Australians "have voted for change".
"My Labor team will work every day to bring Australians together. And I will lead a government worthy of the people of Australia.
"Earlier tonight, Scott Morrison called me to congratulate myself and the Labor Party on our victory at the election. Scott very graciously wished me well."
World reacts
Governments and politicians from around the globe have been quick to congratulate Albanese on his victory. UK Prime Minister Boris Johnson said Australia and Britain had "a long history of a bright future".
"As thriving, like-minded democracies we work every day to make the world a better, safer, greener and more prosperous place," Johnson said in a statement.
India Prime Minister Narendra Modi pledged to work with Albanese "towards further strengthening our comprehensive strategic partnership, and for shared priorities in the Indo-Pacific region".
Dutch Prime Minister Mark Rutte said he hoped to work with Albanese to continue strengthening the "warm broad and intensive relationship" between the Netherlands and Australia.
UK opposition leader Sir Keir Starmer described the result as showing "Australia deserves better".
Former Australia Prime Minister Julia Gillard also offered her congratulations to Albanese, saying the country "has chosen change and progress".
By the numbers
In results so far, Labor had yet to reach 76 of the 151 lower house seats required to form a government alone. Final results could take time as counting of a record number of postal votes is completed.
With 60 percent of the vote counted, Labor had 72 seats and Morrison's coalition 55. Independents and the Greens held 11, the ABC projected.
A further 13 seats remained in doubt.
The centre-left Labor had held a decent lead in opinion polls before the election, although surveys showed the Liberal-National government narrowing the gap in the final stretch of a six-week campaign.
