The poll, taken for The Australian, also shows the Coalition has nudged ahead in two-party-preferred terms to lead Labor by 51 per cent to 49 per cent.
The past two Newspolls had the parties deadlocked at 50-50.
The latest poll shows 55 per cent of voters think the Coalition will win the election while only 25 per cent believe Labor can do so.
The poll of 2049 voters shows satisfaction with Turnbull’s performance has fallen to 39 per cent, well down on the 60 per cent rating he got in mid-November.
Dissatisfaction with Turnbull has risen three points to 44 per cent, leaving his net satisfaction rating at minus five points.
But he remains by far the preferred prime minister, on 52 per cent, compared with 21 per cent for Labor’s Bill Shorten whose net satisfaction rating is up one point to minus 24 points.
The Coalition’s primary vote was unchanged for the third consecutive Newspoll, at 43 per cent while Labor eased back one point to 34 per cent and the Greens stayed on 12 per cent.
