New South Australian Premier Steven Marshall has hit the ground running, stressing the importance of the defence sector to the state economy and flagging big changes in public service management.
Mr Marshall was officially sworn in as South Australia's 46th premier on Monday in a private ceremony at Government House.
Also sworn in were new Deputy Premier Vickie Chapman and Treasurer Rob Lucas.
Ms Chapman becomes the first woman to be South Australia's deputy premier, while for Mr Lucas, it's a return to the role he held in the previous Liberal administration 16 years ago.
Mr Marshall says the rest of his cabinet will be sworn in on Thursday but it's important for the new government to get to work quickly.
"Between us, we have all portfolios at the moment so that we can get on with the job of getting this state back on track," he said.
The new premier's first engagement was signing contracts for the design of a new construction yard for Australia's future submarines.
Mr Marshall used the event to reaffirm his intention to retain the defence industries portfolio because of the sector's importance to the SA economy.
"We know that there is an enormous opportunity from submarines, from ships, from the offshore patrols vessels that are coming our way," he said.
"That's why I want to take this important portfolio."
The new premier also foreshadowed significant changes in public service management describing the arrangements under Labor "chaotic".
"One of the critical things for us is making sure we have a government that takes responsibility," he said.
"We have a situation at the moment where chief executives answer to up to six ministers and that's not good enough."
After Saturday's election win, the Liberals will finish with at least 24 seats in the new parliament and are favoured to pick up at least one of the two still in doubt.
Labor should finish with 19 and there will be three independents.
The issue of the Labor leadership could also be decided this week with former health minister Peter Malinauskas likely to replace Jay Weatherill who announced his decision to stand down on Sunday.
Former treasurer Tom Koutsantis said the party was in no hurry and would pick the best person to lead Labor in opposition.
He dodged questions on whether he would put up his hand and said the party had plenty of great talent to choose from.
"We've all got to get together and have a chat about this and work out what the best arrangement is for the party and the state," Mr Koutsantonis said.
"Ultimately, caucus will pick the next leader of the Labor Party in South Australia."
