Voters are undecided on a preferred successor to Anthony Albanese, with a fresh poll showing a leadership vacuum in the party as nearly half of respondents, 47 per cent, were unable to pick a replacement.

Most respondents in the latest Sky News Pulse poll conducted by YouGov struggled to pick a future leader, with Treasurer Jim Chalmers only leading the field at 26 per cent.

It was followed by Tanya Plibersek at 13 per cent, Richard Marles and Tony Burke at 5 per cent each, and Mark Butler at 4 per cent.

It was one of two new polls showing Labor holding its ground despite backlash over interest rates and Budget housing and tax changes propelling Australia’s biggest market slump since COVID.

Mr Albanese and Dr Chalmers have defended accusations their Budget has crashed the confidence in Australia’s economy as Parliament prepares for its winter break.

Dr Chalmers also told reporters outside parliament on Wednesday morning that Treasury’s assumption in the budget was that house prices will continue to grow “but a bit more slowly”.

“Housing is a long term investment so people shouldn’t get too carried away by weekly and monthly developments in house prices,” he said.

The PM reiterated that treasury estimates tipped “an increase in the value of homes” and defended the measures as an effort to make the market fairer on ABC Breakfast.

“The Treasury estimates are that there’ll be an increase in the value of homes, but it will be slightly lower than it would have been without these measures,” he told ABC.

Shadow treasurer Tim Wilson accused Labor of causing a “crisis in confidence” in the Australian economy.

“Jim Chalmers has crashed the confidence of the Australian economy. Since his federal budget nearly two months ago, what’s happened is a crisis of confidence in the Australian economy,” he said.

Despite criticism over housing market falls the Guardian Essential Poll and Sky News Pulse poll both showed the government was holding despite One Nation’s continued popularity.

The Coalition’s poor run in the polls has continued with plummeting personal popularity of Opposition Leader Angus Taylor.

Coalition dropped three points to 17 per cent of the primary vote, while One Nation was on 30 per cent ahead of Labor on 29 per cent.

The Guardian’s polling showed that Labor’s primary ticked up one point to 30 per cent, while the coalition remained on 23 per cent.

The polls, however, differed on the support for One Nation following Pauline Hanson’s recent “monoculture” comments at the National Press Club address.

Sky’s poll showed the minor party jumped three points to 30 per cent compared to Guardian showing a slump of two points to 26 per cent from 28 per cent in last month’s poll.

Senator Hanson’s speech has continued to cause the popular leader headaches, with the Queenslander using a speech to Parliament this week to address outrage over remarks she made about maternity leave benefits.

In a social media post on Wednesday, Senator Hanson labelled claims that she doesn’t support the benefit as “outright lies and distortions” and insisted she welcomed the July 1 increase to 26 weeks.

“Actually, I supported the 26 weeks paid parental leave passed recently. Anyone who says or implies otherwise is lying to the Australian people,” she said.

“That’s what’s been happening every day since my speech, misrepresentations and outright falsehoods. It’s why Australians’ trust in government, in politics, and in the media is at an all-time low.”
