Malcolm Turnbull's Coalition has lost more ground to Labor, and Pauline Hanson's One Nation is sniffing blood.

The latest Newspoll shows the government trails 45 to 55 percent in two-party preferred terms as Turnbull's popularity takes a nosedive.

One Nation’s primary vote has risen 10 percent, up from eight percent three weeks ago.

Hanson's party rise coincides with US president Donald Trump's appointment to office.

It gets worse for the embattled PM as his lead over Bill Shorten as the preferred prime minister also plummets.

Turnbull currently holds a 40 percent holding over Shorten at 33 percent, however, that seven-point lead was 12-point just three weeks ago.

The poll comes after former PM Tony Abbott undermined the leader during a scathing interview last week.

Abbott said the Turnbull government was perceived by many conservatives as "Labor lite", and risked a "drift to defeat" at the next election if it failed to lift its performance during a speech last Thursday night followed by a television interview.

The latest poll coincides with the resumption of parliament this morning where Labor is expected to oppose recent cuts to penalty rates.
