Opposition Leader David Crisafulli is on track to win the top job, with 44 per cent of respondents indicating the LNP will be their first preference at the ballot box.
Polling by Resolve Strategic, conducted between June and September for the Brisbane Times, showed 23 per cent of voters would put the Labor government, which has held power for nine years, first on the ballot, down three points from May.
Mr Crisafulli is also ahead as preferred premier, with 40 per cent of the poll's 939 Queenslanders giving him the nod, 13 points clear of incumbent Premier Steven Miles.

The polling was carried out during a big spending period and increased campaign announcements, with the government's cost-of-living centric budget plunging the state into a $2.6 billion deficit.
As the polling forecasts a change of government, parliamentarians will sit for the last time this week before voters head to the polls.
The government will introduce a raft of legislation over the next three days including bills covering the state's corruption watchdog's reporting powers and health practitioner misconduct.
Parliamentarians are also set to debate assistive reproductive technology, which introduces a donor conception register in Queensland to ensure families have access to information about their genetic origins.

Debate is expected on Wednesday for working with children and child safety laws, and vaping legislation.
Valedictory speeches will be held for retiring MPs on Thursday.
Mr Miles took aim at the opposition on Monday, ahead of the parliament's final sitting.
"Like all sitting weeks, we'll go in there with clear plans for our state and our future, and we'll talk about those," he said.
"The opposition will come in and yell and scream and make fools of themselves."
The last time the LNP held power in Queensland was between 2012 and 2015, when Campbell Newman won the largest house majority in state history.
The Newman government held 78 of 89 seats.
