Labor looks to be in the box seat to form a majority government, claiming victory in a 47th seat as the official vote count continues.

The party says its candidate Meaghan Scanlon has won the Gold Coast seat of Gaven over sitting Liberal National Party member Sid Cramp.

Ms Scanlon, 24, will be the youngest female state MP in Queensland's history, and says she is proud to be given the opportunity.

"Very clearly voters here on the Gold Coast wanted an energetic, enthusiastic change from the wall-to-wall LNP MPs who took this area and my community for granted," Ms Scanlon told reporters on Wednesday.

"I know there'll be a lot of new challenges, really looking forward to getting in there."

The declaration of victory in Gaven means Labor looks likely to win 47 seats, which would give it a one-seat majority in the new 93-seat parliament.

The electoral commission is yet to formally declare Gaven or Macalister but it has declared 34 seats - 18 for Labor, 15 for the LNP and one for Katter's Australia Party.

The one KAP seat is leader Rob Katter's north Queensland seat of Traeger.

It follows independent candidate for Macalister and child safety campaigner Hetty Johnston conceding defeat to her Labor opponent on Tuesday.

However, the party is confident of picking up Shane Knuth's new seat of Hill, and on Wednesday declared victory in Hinchinbrook, where candidate Nick Dametto was in second place and looked to pass LNP incumbent Andrew Cripps on preferences.

"It's been a six-year project for us to get another seat in parliament and we've done that so we've demonstrated the strong growth that we can achieve when we're doing our job," Mr Katter told reporters on Wednesday.

"I think we've got a very strong mandate now to be the representatives for north Queensland."

Labor has yet to claim victory overall and LNP leader Tim Nicholls has not conceded defeat, meaning both sides might wait until the Electoral Commission of Queensland formally declares a result.

Nearly 90 per cent of the statewide first-preference vote has been counted and the ECQ hopes to have a final result by the end of the week.
