CANBERRA — Anthony Albanese, who won Saturday's election with the opposition center-left Labor Party, said Australia could become a renewable energy superpower.

He is to be sworn in as PM on Monday, but it is not clear whether his party will have a majority in parliament.

Climate change was a key concern for voters, after three years of record-breaking bushfire and flood events.

Outgoing PM Scott Morrison, the leader of an ousted Liberal-National coalition, thanked the "miracle of the Australian people" after conceding.

Vote counting is still going on, and it is unclear whether Labor can get 76 seats to secure a majority in the 151-member lower house of parliament.

Final results may not be known for several days, as electoral officials have just started counting nearly three million postal votes.

If the election results in a hung parliament, Greens and independents — who have been campaigning for radical climate change action — could wield greater influence in framing the new government's policies on the issue.

"Australian businesses know that good action on climate change is good for jobs and good for our economy, and I want to join the global effort."

Albanese, who will be heading Australia's first Labor government in almost a decade, also promised to adopt more ambitious emissions targets.

However, he has so far refused calls to phase out coal use, or to block the opening of new coalmines.

Albanese will fly to Tokyo on Monday for a summit with the leaders of Japan, India and the US, known as the Quad. As he will be representing Australia as its prime minister, he will be sworn into office before his departure.

"Obviously the Quad leaders meeting is an absolute priority for us," he told journalists on Sunday.

"It's an opportunity for us to send a message that there is a change of government and that there will be a change of policies on things like climate change.

"I will return to Australia on Wednesday and then we'll get down to business."

He said he wanted to "change the country and change the way that politics operates in this country".

One of Australia's longest-serving politicians, Albanese served briefly as deputy prime minister to Kevin Rudd in 2013 and has long been a favorite of his party's left wing. Since becoming opposition leader in 2019, he has positioned himself more towards the center.

"What Australians have endured over these past few years has shown a tremendous depth of character and resilience and strength," the outgoing prime minister said.

UK Prime Minister Boris Johnson said he looked forward to working with Albanese "in the weeks, months and years ahead as, together, we tackle shared challenges and demonstrate the importance of our shared values".

New Zealand's PM Jacinda Ardern said she had "a warm conversation" with Albanese, describing Australia as "our most important partner".

Indian Premier Narendra Modi also congratulated Albanese on his party's election victory. — BBC
