Opposition MPs are delighted with a new opinion poll showing their leader's popularity is on the rise.
Voter satisfaction with the opposition leader has increased 15 percentage points since Malcolm Turnbull took over from Brendan Nelson less than a month ago, according to the latest Newspoll.
Prime Minister Kevin Rudd also reversed a drop in his satisfaction rating, jumping six points to 56 per cent, assisted by his handling of the global financial crisis, the Newspoll in Tuesday's The Australian newspaper shows.
Mr Turnbull's 50 per cent rating is nine points higher than Mr Rudd's when he became Labor leader in December 2006, The Australian says.
"There's no doubt it's good for the party," Liberal MP Stuart Robert told reporters in Canberra.
"It's no doubt having someone like Malcolm Turnbull, with his capacity, his intelligence, his foresight, is not only good for the party but good for the nation."
Mr Robert rejected suggestions Mr Turnbull was arrogant.
"You can't come out there and say that Malcolm Turnbull has a problem from a humility point of view," he said.
Liberal colleague Andrew Southcott was encouraged by the poll result, but said it was too early to celebrate.
"Those polls are encouraging but politics and federal elections are like a marathon, it is now two years to the next election but the opposition is in good shape," Dr Southcott said.
Labor MP Jason Clare said he was not worried by the poll result.
He attacked Mr Turnbull for reportedly having criticised his own party's plan to cut the petrol excise, then refusing to change that policy when he became leader.
