MALCOLM Turnbull has lost ground to Bill Shorten as preferred prime minister as the Coalition slips to another low in popular support, according to the latest Newspoll.
The Australian reports the Turnbull government trailing Labor by 46 to 54 per cent in two-party terms.
Mr Turnbull's rating as preferred prime minister has plummeted by four points from the last Newspoll, going from 46 to 42 per cent.
Opposition Leader Bill Shorten's, however, has increased by two points, taking him up to 31 per cent.
In the primary vote, support for the Coalition dropped from 37 to 36 per in the past three weeks.
It is the 20th consecutive Newspoll where Labor is in front of the Coalition.
The result comes after Mr Turnbull worked to assure Australian households he was fighting to drive down energy costs, calling electricity company chiefs to Canberra to outline ways to help customers get better deals.
The Newspoll, conducted from Thursday to Sunday, surveyed 1695 voters and has a margin of error of 2.4 per cent.
