The LNP is leading the two-party preferred vote 54 per cent to 46 per cent, the latest Newspoll, published in News Corp papers revealed.
This could mean the LNP wins an extra 18 seats in the October election - enough to make a majority government, according to the Newspoll.
The opposition is also leading the primary vote, by 42 per cent to 30 per cent.
Labor's primary vote is down 10 points since the last state election in 2020, which they won under the leadership of former Premier Annastacia Palaszczuk.
The LNP recorded a six point uptick in the same period.
Premier Steven Miles has been in the top job since Ms Palaszczuk's shock resignation in December.
Mr Miles' approval ratings are behind Opposition leader David Crisafulli's 37 per cent to 43 per cent.
Twenty per cent of the 1037 people surveyed were undecided on their preferred premier.
The newspoll comes ahead of Saturday's Inala and West Ipswich by-elections, which are expected to provide an early litmus test for the government ahead of the October election.
Mr Miles told reporters on Monday he expected to see a double digit swing at Ipswich West.
"The last time we had a similar by-election in an Ipswich electorate was the Bundamba by-election and we saw a more than 12 per cent swing there," he said.
