The Queensland election is too close to call, the latest poll shows, with more indications the Newman Government will not go to the ballot box early.

The Roy Morgan poll of 1,179 Queenslanders, via text, found the ruling Liberal National Party had gained some ground, one percentage point, since October.

On a two-party preferred basis, the LNP were just ahead, leading Labor 50.5 per cent to 49.5 per cent.

The LNP had 39 per cent of the primary vote, compared to Labor's 36.5 per cent and Palmer United Party's 4 per cent.

The poll, taken between November 21 and 24, also showed Premier Campbell Newman trailed Opposition Leader Annastacia Palaszczuk in the preferred leader stake, 47.5 per cent to 52.5 per cent.

Mr Newman has repeatedly said he intended to run a full term, meaning the poll could be expected in late March.

The state election can be held no later than June.

The Government this week introduced changes to how development applications are categorised and assessed and wants the bill passed before the next poll.

A parliamentary committee has to seek public submissions, hold public hearings and report back before the Government can pass the bills and call the election.

That cannot happen before the first sittings of Parliament in February, but could be even later than that.
