Women have led the Labor charge in South Australia, winning five seats for the incoming government, as the party looks to change the culture in parliament and pursue its bold policy agenda.
As counting continued following Saturday's poll, Labor looked set to hold at least 25 of the 47 House of Assembly seats and was leading in two more.
The defeated Liberal government was on track to retain at least 15 seats but was only marginally ahead in outgoing Premier Steven Marshall's eastern suburbs electorate of Dunstan.
Mr Marshall indicated on Sunday he wanted to continue to serve as the local member but would not seek to lead the Liberals in opposition.
Labor's gains on Saturday included the seats of Adelaide, Newland, Elder, King and Davenport, all won by women candidates.
Premier-elect Peter Malinauskas said they would bring passion, intellect and youthful energy to the Labor team.
'I stand here today as the leader of modern Labor Party that reflects our society, a very high proportion of female members of parliament.
"This is what modern Labor looks like."
Incoming Deputy Premier Susan Close said it had been important for Labor to have the right leader, the right policies and a united team.
"Finally, we needed the right candidates," she said.
"Peter and I talked long and hard about making sure we got renewal, making sure that we had talent and making sure we had enough women coming into parliament to really change the culture and make it a better place."
Mr Malinauskas said he was determined to pursue all Labor's policies, including fixing problems in health, improving skills training, building more public housing, bringing back the V8 Supercars to the city centre, and expanding pre-school to three-year-olds.
"Clearly, the task before us is very substantial, we've got a number of issues that we'd like to address within the community," he said.
"Some are going to be difficult, some are going to be challenging and take some time, others are particularly urgent.
"But it's a task that we are wholeheartedly committed to.
"We get to work today. There isn't a moment to lose."
In a statement, Mr Marshall said that after more than nine years as leader of the Liberal Parliamentary Party it was time for someone else to take charge.
"I will step down as leader as soon as the party room is able to meet to elect my successor," he said.
"I thank all my past and current colleagues for their support over the past nine years and will do all I can to assist the new leader to succeed."
The outgoing premier said while he was disappointed with the election result, he took full responsibility and accepted the will of the people.
In other results, independents Dan Cregan in the Adelaide Hills, Geoff Brock, who shifted to the seat of Stuart in the mid-north, Troy Bell in Mt Gambier and Fraser Ellis in Narungga, which takes in Yorke Peninsula, are all set to be returned.
Mr Brock's win in Stuart meant the departure from the parliament of Deputy Premier Dan van Holst Pellekaan.
In Finniss, independent Lou Nicholson was leading Liberal David Basham after the outgoing primary industries minister was on the wrong end of a 19 per cent swing.
Another former minister was in trouble in Gibson, where Corey Wingard trailed Labor's Sarah Andrews.
It's expected arrangements for the transition of government will be finalised in the coming days to allow Mr Malinauskas to be sworn in as the state's 47th premier.
