As Daniel Andrews vows to get back to work after a resounding election win in Victoria, Opposition Leader Matthew Guy faces increasing pressure to step down.
Labor will return to majority government with as many as 16 more seats following the ballot result that shocked even the winners.
"The people of Victoria have today overwhelmingly endorsed a positive and optimistic plan for our state," he told the cheering sea of supporters.
"They have in record numbers, at the same time, rejected the low road of fear and division."
Labor could win as many as 60 seats in the 88-seat parliament, 15 more seats than it had before Saturday's election.
"We will make sure that regardless of how you voted, we will have better schools, we will have better hospitals, we will build the infrastructure we need," Mr Andrews said during his victory speech last night.
Frontbench MP Jill Hennessy had earlier described the outcome as a "bloodbath".
Mr Andrews, who was flanked by his wife Cath and his three children, was greeted by cheers and chants of "Daniel, Daniel" as he entered the Labor election party in Melbourne.
He also thanked staff and campaign volunteers, and his family including his three children.
"They are the future and that's why we fight so hard for the things that we believe in," he said.
He also thank Liberal leader Matthew Guy for his gracious concession he made in a personal call earlier on Saturday night.
Labor supporters jubilant
Labor supporters celebrated early on as the numbers pointed to a big swing to Daniel Andrew's party.

'A bloodbath'
The Liberal-National coalition will struggle to get close to the 37 seats it held going into Saturday's election, with only 16 confirmed so far.
Health Minister Jill Hennessy said Labor was doing well in areas it did not usually perform in and in the Melbourne sandbelt seats.
"This is looking like a bloodbath," she told the ABC as the numbers pointed to a confident Labor win.
The Greens, which were angling to form minority government with Labor, will not have a kingmaker role.
Australian Greens leader Richard Di Natale congratulated Daniel Andrews.
"I want to congratulate Daniel Andrews and the Labor Party," Senator Di Natale said from the Greens' post-ballot function in Melbourne.
"What we have seen is Victorians comprehensively reject a really awful campaign based on law and order, trying to divide the Australian community."
Victorian Greens leader Samantha Ratnam said she remains confident her minor party would win two extra lower-house seats in the state's 59th parliament.
Campaigning was focused on the inner-Melbourne electorates of Richmond and Brunswick.
"We hope they will become green for the very first time," Ms Ratnam told the Nine Network.
Federal Liberal party blamed
Matthew Guy conceded defeat and offered his congratulations to Premier Daniel Andrews on Labor's overwhelming victory in the Victorian state election.
Mr Guy, with his wife Renae by his side, called for unity in the party as it faces another four years in opposition and demands for an overhaul of the party.
"Can I say for the next parliament, as a party, we need to stick together. We need to stay united and we need to stay focused on our opponents and the game ahead, not on ourselves," he said.
He also thanked his staff, candidates, campaign volunteers and his family. And he thanked for Liberal voters for keeping the faith.
"Every day in opposition is a day closer to government and while tonight is not our night, we know that, we acknowledge that, we accept that, our time in the sun will come again."
