A poll bounce and a promise to reset controversial policies have given Prime Minister Tony Abbott some breathing space from leadership rumblings.

The latest Fairfax-Ipsos poll puts the coalition slightly behind Labor 49-51 per cent, up from the 46-54 result in January.

Critics of the prime minister have pulled back from talk of a second leadership spill motion during this week's parliamentary sitting.

Liberal backbencher Dennis Jensen, who was one of 39 MPs to back the spill three weeks ago, summed up what many of his colleagues were thinking.

"It's a positive result," he said of the poll on Monday.

"The prime minister is changing the way that he's doing things and I think that that is being reflected in public sentiment."

Asked whether a vote would go ahead, Dr Jensen said: "I wouldn't think so. I certainly would hope not ... the prime minister should genuinely be given time."

This week the government is expected to announce whether it will dump the controversial Medicare co-payment, unveil details of a further troop commitment to Iraq and release the five-yearly Intergenerational Report.
