It's not clear if Liberal National Party support is increasing or falling in Queensland, but voters still rate it well ahead of Labor.

Two polls released on Monday reveal differing trends, but both show the LNP would still decisively defeat Labor in an election.

A ReachTEL poll shows primary support for the LNP rose by almost five per cent to 47.1 per cent over the last month, but a Galaxy poll indicates it fell to 43 per cent, down one per cent since November.

Labor's primary support slid by six per cent to 28.9 per cent, according to ReachTEL, but Galaxy respondents put support up at 34 per cent.

Premier Campbell Newman's management during the ex-tropical cyclone Oswald floods impressed ReachTEL respondents, with 20.8 per cent saying he is doing a very good job, up from 18.1 per cent in January.

But Galaxy says Mr Newman's support has fallen, with people unimpressed by his performance rising by four percentage points.

Opposition Leader Annastacia Palaszczuk isn't faring well either with 18.6 per cent of ReachTEL respondents saying she is doing a very poor job, up three per cent since January.

Galaxy shows Ms Palaszczuk has recorded a seven percentage point increase in the number of people dissatisfied with her performance.

The ReachTEL poll shows 0.5 per cent of respondents don't know who Mr Newman is, while 13.5 per cent of respondents have not heard of Ms Palaszczuk.

The response to a separate question in that poll, asking people if they believe the Newman government should lift the ban on uranium mining in Queensland, will be released at a later date.
