"I thank you from the bottom of my heart and I will return that respect every single day."

LNP leader Deb Frecklington conceded defeat and congratulated the Premier on her victory as she spoke to her supporters in Brisbane.

"I may not agree with the Premier a lot of the time but I respect her as an opponent and as the leader of our state," she said.

"Most of all I respect the voters of Queensland and we are so privileged to live in this democracy."

The Opposition Leader also said she plans to stay on as party leader.

"I will continue to play my part in the Liberal National Party and I will continue as leader of this great party," she said.

"The LNP is going to continue to hold the Palaszczuk government to account."

Federal Liberal MP Peter Dutton told 9News sabotage within the LNP contributed to Ms Frecklington's defeat.

The Minister for Home Affairs said it was "very clear" detailed misleading information was leaked during the campaign to negatively impact the LNP leader.

Nine projects Labor will claim 50 seats, three more than the number needed to form a majority government.

Katter's Australian Party is set to win three, and One Nation is projected to hold the seat of Mirani.

The Greens look likely to secure two seats, including South Brisbane, where the party's candidate Amy MacMahon defeated former deputy premier Jackie Trad.

Twelve other seats remain in doubt.

Nine's Political Editor Chris Uhlmann said it was a historic night for Annastacia Palaszczuk and the Labor Party.

"It was pretty much never in doubt after the first hour of counting," he said.

"It's an extraordinary result and Annastacia Palaszczuk paints herself into the history books as one of the great Labor heroes."
