Incoming South Australian premier Steven Marshall has promised to deliver every pledge announced by the Liberals in the lead-up to the state election, and vowed to get the state "back on track".
Mr Marshall on Sunday met with Governor Hieu Van Le to inform him the Liberal Party had reached a majority and intended to form government.
On his first day as premier, Mr Marshall said the Liberals would mark off every item in the 100-day plan they released earlier this year.
"We're going to lower people's taxes, we're going to lower their cost of living and we're going to create more jobs in this state," he told reporters.
Mr Marshall said South Australian could expect a cut to their emergency services levy bill from July 1, but would not say which of his policies would be implemented first.
Fresh from his victory celebrations of Saturday night, said the Liberals' early decision to rule out doing a deal with Nick Xenophon's party had paid off.
"The party room backed my position that we wouldn't do a deal and I think that's one of the turning points in the campaign," he said.
"I'm particularly delighted that the people of South Australia backed us into a majority government because I genuinely believe that is exactly what we need in South Australia."
Sitting MP Vincent Tarzia was singled out for praise for seeing off Mr Xenophon's attempt to steal his seat of Hartley from him.
But on Sunday, Mr Marshall shifted the focus to the efforts of his entire team in returning the Liberals to power for the first time since 2002.
"I just really want to emphasise there is no one person or group of two or thee people, I'm extraordinarily grateful to every person in the team," he told reporters.
"It's a little bit like a football team - you can't all be the centre-half forward."
Mr Tarzia, who leads Mr Xenophon 58.6 to 41.4 in the two-party preferred vote, served as shadow cabinet secretary during his first term in parliament.
The Liberals ended 16 years of Labor rule at Saturday's state election, claiming at least 24 seats in the 47-seat parliament - enough to govern in their own right.
The new premier said his current shadow cabinet would keep their positions in the transition to government.
"There may be some minor tweaking of portfolios but nothing too substantial," he said.
As well as Mr Xenophon's personal defeat in the seat of Hartley, his SA-BEST party failed to claim any of the other 35 lower house seats it contested.
The party has won two seats in the state's upper house.
