Opposition Leader Malcolm Turnbull is planning a broad reshuffle of his frontbench in a move the ABC understands is designed to regain some momentum.

His stocks are low at the moment and three opinion polls out this morning will be of no comfort.

Mr Turnbull needs some new momentum and Liberal sources have told AM Mr Turnbull is working on a broad frontbench reshuffle to announce over Parliament's winter break to help provide that.

With senior Liberals questioning his judgement last week, putting it down to his lack of experience, it is believed he is looking at bringing some of the hard heads in the party much closer to the frontline.

Those more seasoned operators mentioned - Andrew Robb, Tony Abbott and Tony Smith - have all served in backroom roles before they entered Parliament.

Mr Abbott had a good week last week, leading the tactics inside Parliament and defending Mr Turnbull on the outside.

Sources say MPs and staff have all noted how good his performance was.

It is understood he may get his wish to move closer to the action in what is tipped to be a more combative role.

Mr Smith, who is currently in a junior economic portfolio may also be asked to step up - a reversal of fortunes for him after he voted for Brendan Nelson when Mr Turnbull took the leadership.

After last week, Liberal sources say they looked lean by comparison to the ruthless political machine they were up against.

Crushing poll results

The latest polls, taken at the end of last week and over the weekend, show potentially crushing news for Mr Turnbull.

While the Coalition's ratings have fallen, Mr Turnbull's have plummeted.

His approval in the Nielsen poll is down 11 points to 32 and his disapproval up by more to 60.

In Newspoll his satisfaction rating has slumped by nearly half to 25 and his dissatisfaction rating has risen by a similar amount.

On the contrary, Labor's stocks have risen across the board - in the Nielsen poll in the Sydney Morning Herald and The Age, the Galaxy poll in News Limited state papers and Newspoll in the Australian.

In both the major polls Mr Rudd is up and at 65 per cent or over as better prime minister, Mr Turnbull is down to 25 in the Nielsen poll and to 18 in Newspoll.

To add insult to injury in the Galaxy poll, only 7 per cent believe Mr Turnbull has been honest on the OzCar scandal. Nearly five times more people believe Mr Rudd has been honest.

Overall the polls show Labor has widened its lead over the Coalition.

Newspoll has the ALP ahead by 56 per cent to 44 after preferences.

Mr Abbott has told AM Mr Turnbull's performance in the polls is a result of "the firestorm of smear which the Labor Party directed against Malcolm Turnbull."

Having lost a $20 bet to Deputy Leader Julia Gillard two weeks ago on Peter Costello's future, Mr Rudd will be glad he did not put money on a prediction made to Rove McManus on Channel Ten about the effect of the OzCar affair.

"You know what happens when people throw mud, some of it sticks. I'm sure in the opinion polls we'll see some damage," Mr Rudd said.

"Now I'm looking to get myself a car; you know any good dealers in Queensland I could...?" McManus asked last night.

"Not off hand, but I'm sure Malcolm Turnbull could email you some suggestions," Mr Rudd responded.
