Poll shows Turnbull support dipping

Malcolm Turnbull's standing as preferred prime minister has dipped, the latest Newspoll shows, although the coalition has maintained its core support at 36 per cent.

Mr Turnbull's popularity has dipped one percentage point, to 41 per cent to 33 per cent for Opposition Leader Bill Shorten, who is up two percentage points from three weeks ago.

Labor's lead in two-party terms is solid despite a percentage point drop in its core support, from 38 per cent to 37, according to the poll conducted exclusively for The Australian shows.

It leads the coalition 54 per cent to 46 despite major government decisions in the past three weeks on private health insurance, domestic gas supply and funding for critical medications.

Meanwhile the minor parties continue to gain ground. The Greens are up one percentage point to 10 per cent, helping Labor to keep its lead on the coalition in two-party preferred terms.

Pauline Hanson's One Nation Party has increased its support from 8 to 9 per cent in the same period.
