Turnbull government slumps in Qld, poll

The Turnbull government would need the preferences of Pauline Hanson's One Nation party to retain the electorally-critical state of Queensland, a new poll shows.

Support for the coalition there has slumped eight points to 35 per cent since last year's federal election and it narrowly leads Labor 51-49 on two-party-preferred basis, the Galaxy poll in the Courier-Mail on Tuesday showed.

Most of the coalition support has gone to One Nation, whose primary vote has risen 5.5 points to 18 per cent, according to the poll.
