The Coalition has failed to deliver a meaningful alternative to Labor's proposals to restrict negative gearing to new properties. The policy vacuum has turned voters away from the Coalition, which, until recently, was enjoying soaring opinion polls.

The most recent Newspoll survey show the Coalition's primary vote has slipped to 43%, its lowest level since Turnbull became Prime Minster four months ago. The Coalition's lost support has not translated directly to support for the Labor party. The primary vote for each of Labor, the Greens, and independents rose only 1 point.

The poll showed that 47% of voters surveyed were in favour of Labor's negative gearing plan, while 31% were opposed to it, and 22% were uncommitted at this stage.

The Turnbull government has also been impacted by a general failure to provide economic direction, and ministerial resignations which have triggered a cabinet reshuffle.

Despite a nine-point decline, Turnbull's preferred-PM rating of 55% remains well ahead of Bill Shorten's 21%.

The Newspoll survey is based on 1,807 interviews with voters around Australia.
