Labor will not be moving from Brisbane's Tower of Power for the next three years, with the Electoral Commission of Queensland officially declaring the party has won the 47 seats it needed for a majority.
Premier Annastacia Palaszczuk visited Governor Paul de Jersey on Friday afternoon to advise she had the numbers for her government to be re-elected.
Giving her first press conference after Labor claimed the win in the state election, Ms Palaszczuk delivered her verdict on the LNP's leadership race.
If the LNP did not back Deb Frecklington in her bid to become opposition leader, re-elected Queensland Premier Annastacia Palaszczuk predicted, the conservative party could break apart.
"Far be it for me to comment on the opposition, but if the LNP does not back Deb Frecklington, I fear that the Nationals will break away from the LNP," Ms Palaszczuk said.
"So there's a lot riding on who they select."
The Liberal and National parties merged in Queensland in 2008, after years of state political wilderness for the then-coalition.
Opposition leader Tim Nicholls called Ms Palaszczuk to concede the election on Friday morning, before the Electoral Commission of Queensland officially called 47 seats for Labor, the number required for a majority.
Mr Nicholls said he would not recontest the LNP leadership, with his deputy Ms Frecklington and former LNP leader John-Paul Langbroek both announcing they would vie for the position on Tuesday.
Ms Frecklington, the member for Nanango, was from the Nationals side of the LNP, while Mr Langbroek was a Liberal.
However, whoever won, Ms Palaszczuk, the first Australian woman to win a state election from opposition, and then be relected, was unfazed.
"From where I sit, I think I've stared down Campbell Newman, I've stared down Lawrence Springborg, I've stared down Tim Nicholls," she said, from level 41 of 1 William Street.
"So who's next? It doesn't really bother me."
Ms Palaszczuk said Labor would hold a caucus meeting on Monday and her new cabinet would be sworn in on Tuesday.
