Bill Shorten has pulled ahead of Tony Abbott as preferred prime minister in the latest Newspoll, as voters expressed their dissatisfaction with Abbott’s performance on the world stage.

Shorten’s rating as preferred prime minister has jumped from 38% a fortnight ago to 43% now. Abbott lost ground, falling from 39% to 37%. It’s the first time Shorten has polled ahead of Abbott in three months.

Labor extended its lead in the two-party preferred stakes to 10 points, ahead 55% to the Coalition’s 45%. It is Labor’s 14th consecutive lead over the Coalition.

The Coalition’s primary vote also fell, hitting a four-month low of 36%. Its vote at the last federal election was 45.6%. Labor’s primary vote rose three points to 39%, up from 33.3% at the last federal election.

The Greens’ primary vote has fallen two points to 11%, while the “other” category, which includes independents and the Palmer United party, has gained one point to sit at 14%.

Abbott’s personal approval rating has also fallen one point to 36%, while his dissatisfaction rating has soared three points to 55%, his highest since August.

Shorten’s approval rating is up two points to 39%, while his dissatisfaction rating is down four points to 41%. A significant 20% are still remaining uncommitted, however.

The poll has a three-point margin of error.

The survey recorded the opinion of 1,166 people, and was conducted on Friday and across the weekend, at the time Abbott was hosting world leaders at the G20 conference in Brisbane.

Since the last Newspoll, the government has managed to pass its Direct Action climate policy, but also controversially introduced a higher fuel excise, meaning motorists have to spend more filling up.
