Queensland Opposition Leader Tim Nicholls says neither Labor nor the LNP has won a majority government at the end of counting on Saturday night.
"What is abundantly clear is that Queenslander have voted to shake things up," he told an LNP election night function.
He said between 10 and 14 seats were still in doubt, and they would determine the outcome of the election.
At the end of counting on Saturday night, Labor had 43 seats, the LNP 37 and Katter's Australian Party two.
Just moments earlier, Premier Annastacia Palaszczuk said she was confident Labor would be able to form a majority government once all votes were counted.
Mr Nicholls said Ms Palaszczuk must now keep her promise that she would not make any deals with the Greens, One Nation, KAP or independents to form government.
"I have always said that I will respect the will and the vote of the people of Queensland and I will keep my word on that respect," he said.
"I will keep my word. The real question, the real question for tonight is will Annastacia Palaszczuk keep her word?"
