The government spent last week ripping itself to shreds, culminating in Scott Morrison replacing Mr Turnbull as prime minister and Josh Frydenberg taking over as treasurer.

The latest Newspoll taken just after Friday's leadership showdown shows the coalition's primary vote has slipped to 33 per cent, the worst result in a decade.

On a two-party preferred basis, Labor holds a commanding 56 per cent to the government's 44 per cent.

"The polls today are the biggest surprise since the sun coming up tomorrow," Mr Frydenberg told 3AW on Monday.

He said there would be no early election, arguing the new leadership team needs time to lay out its agenda.

"The last week was a very difficult week for the party and my colleagues but we do need to move on," the treasurer said.

Defence Industry Minister Steve Ciobo said voters don't want a forensic examination of the leadership spill, they just want the government to focus on them.

"I think what the Australian public expect of us is to outline a clear policy, what we're going to be doing and how we're making their lives better," Mr Ciobo told Sky News.

"I don't actually think they have much appetite at all for some kind of introspection about what happened."

Former prime minister Tony Abbott, who played a key role in sparking the leadership crisis, believes the polls will trend upwards under Mr Morrison.

"We've had far too much backstabbing, we've had far too much leaking and briefing and I think we can now put all of that behind us," Mr Abbott told 2GB.

Finance Minister Mathias Cormann admitted the leadership crisis had taken a toll on the government's stocks.

"We had a very difficult week last week. In that context the result today is not surprising," Senator Cormann told the ABC.

A fortnight ago the opposition held a narrow two-party preferred lead of 51-49 per cent in front.

Newspoll also has Bill Shorten as more popular than Mr Morrison, 39 per cent to 33 per cent, after the Labor leader trailed Mr Turnbull in the previous poll by 12 points.

"I don't think any of us here needed an opinion poll to tell us how angry, confused and annoyed Australians are with the Government," Mr Shorten told reporters.

"The Morrison government still hasn't told us why Morrison is the prime minister."
