Australian Labor Party (ALP) primary vote has reached a three-month low of 30 percent, and nearly one in two voters are backing the Coalition, giving it a 16- point lead after preferences, the latest Newspoll showed on Tuesday.

According to the Newspoll survey, conducted for The Australian last weekend, voters have pushed the Coalition's primary vote support to a three-month high of 49 percent, with Labor one point lower at 30 percent.

Analysis from local media said that if the results were replicated on election day with a uniform swing across the country, Labor would lose 35 seats.

And the analysis considered that in the past two weeks, Julia Gillard was the biggest loser, with a three-point fall in voter satisfaction wiping out most of a five-point gain since the end of March. Dissatisfaction with Prime Minister rose three points to its highest since the end of March.

Compare to this, the Opposition Leader Tony Abbott has improved three points in the two weeks since the last poll to achieve a 43 percent result amongst voters. And on a two party preferred basis, the opposition holds a commanding 16 point lead - 58 percent (up two points) to Labor's 42 percent (down two points).

In addition, Julia Gillard's support in this survey as preferred prime minister fell four percentage points to 35 percent, the lowest since March, and Tony Abbott's rose three points to 43 percent, his highest since March.
