The political marriage of the state's Liberal and National parties was formalised beneath a shower of confetti.

Making his first speech as leader-elect of the amalgamated Liberal National Party (LNP), Lawrence Springborg heralded a "new model of government" in Queensland - a model "more resilient and more rewarding".

Before a crowd of exultant LNP faithfuls, Mr Springborg signalled the end to a movement initiated by former Prime Minister Robert Menzies in 1944.

"This is a journey to be proud of," he said.

"Mark July 27 in your diaries as a day in history."

He hailed the historic unification as the force to end the state Labor Government's 10-year rule.

"We will fix the roads; we will fix the hospitals; we will fix the education system in Queensland; and we will fix water once and for all," he said.

Mr Springborg promised Queenslanders they would be able to wash the sand off their feet at the beach.

The merger met factional resistance within the Liberal Party last week but both conservative parties voted at separate party conventions yesterday to amalgamate to form the Liberal National Party.

The new party comes into being after weeks of tense negotiations, which climaxed on Friday with legal action over the Liberal state council's attempt to delay the convention called to vote on the merger.

Following the vote, the wall dividing the two meetings in Brisbane's Sofitel Hotel was removed to jubilant scenes.

Exuberant LNP supporters continued the triumphant celebrations in the Sofitel's Grand Ballroom today as Bruce McIver stood before them as LNP's inaugural president.

Placards reading "Go the Borg" officially dissolved Queensland Liberal president Mal Brough's bid for a Liberal LNP leader.

Mr Brough and Alan Stockdale were behind moves last week to stall the merger; the pair insisted the party's proposed constitution would set it adrift from the federal Liberal Party.

However, federal Liberal Leader Brendan Nelson has endorsed the new party.

Mr Brough said he would not join the LNP, and had not decided his political future.
