New South Australian Premier Steven Marshall faces a test to get his reform agenda through state parliament, even before his full ministry is sworn in.
The new premier believes that after the Liberals' emphatic election win, he has a mandate for such policies as deregulating shop trading hours.
But the Greens have warned that every piece of legislation will be scrutinised.
Upper House MP Tammy Franks, who looks set to be returned as one of two Greens in the Legislative Council, says the Liberals will only have eight of 22 votes in the chamber and has rejected Mr Marshall's mandate claims.
"Steven Marshall might be 'the man' but that does not mean the Greens will be acquiescing to his so-called mandate," she said.
"We will be using our votes to test every piece of legislation on its own merit."
So far only Mr Marshall, Deputy Premier Vickie Chapman and Treasurer Rob Lucas have been sworn in, with the rest of the premier's new cabinet to make the trip to Government House on Thursday.
On Tuesday, the new premier was said to be "working through the machinery of changing government" as counting continued to determine the final make-up of the new parliament.
The Liberals look set to finish with 25 seats with Labor on 19 and three to be held by independents.
But one Labor and one Liberal seat remain in doubt.
Rachel Sanderson, who is tipped to join Premier Marshall's cabinet, is ahead by more than 500 votes in the battle to retain her seat of Adelaide with 76 per cent of the vote counted.
She has managed to claw her way back into the contest after trailing Labor's Jo Chapley by around 100 votes on Monday.
Ms Sanderson is expected to move further ahead on postal and pre-poll votes but is yet to claim victory.
"Not having a definite outcome is certainly stressful but I am very hopeful that I will be part of a Marshall Liberal government," she said on her Facebook page.
While in the seat of Mawson, former Labor tourism minister Leon Bignell leads Liberal challenger Andy Gilfillan by less than 200 votes.
Mr Bignell faces a tough challenge to keep his seat after boundary changes turned it from a marginal Labor seat to marginally Liberal.
While he still leads, pre-poll and postal votes are expected to favour Mr Gilfillan.
