Opposition leader Tim Nicholls has brushed off a new poll suggesting support for the Liberal National Party is in freefall.

A new Galaxy poll of 900 Queenslanders shows support for the LNP has dropped to a five-year low of 32 per cent ahead of the state election.

"Polls will come and go, you know I don't comment on polls," Mr Nicholls said on Saturday.

"The most important poll is the poll that will be held in three weeks time on the 25th of November."

Mr Nicholls said he had had not changed his position on preferencing One Nation on a seat-by-seat basis as the minor party's support continues to climb.

Pauline Hanson's One Nation vote has risen from 15 per cent to 18 per cent in the past three months, while support for the Liberal National Party has fallen to 32 per cent and the Labor vote is unmoved at 35 per cent.

If these numbers remain the same, neither major party is likely to win a majority.

One Nation state leader Steve Dickson last month likened Labor and the LNP avoiding a deal with the minor party to dying of thirst.

"It's like drinking water. Without it, you die. At the end of the day, you're going to have to come and have a drink. We're holding all the water," he told ABC radio.

Premier Annastacia Palaszczuk has previously stated she would not enter into a deal with One Nation, even if it meant losing government.

The poll, published in the Courier Mail on Saturday, shows 43 per cent would choose Ms Palaszczuk as preferred premier over Mr Nicholls, while 28 per cent said they remained uncommitted to either.

Since August, the number of people satisfied with Ms Palaszczuk has increased by two per cent to 41 per cent satisfied, while those dissatisfied has decreased to 42 per cent.

The poll shows 40 per cent were dissatisfied with Mr Nicholls' performance, but 32 per cent remained uncommitted.
