NSW Premier Barry O'Farrell isn't concerned by a poll showing the coalition trailing Labor.
The latest Fairfax-Nielsen poll released on Saturday shows the opposition is leading the coalition 51 per cent to 49 per cent on a two-party preferred basis.
That's the first time Labor has led the government in the poll since 2008, and represents a 15 per cent swing since the March 2011 election.
A Newspoll survey published in the Daily Telegraph on Monday found the coalition still ahead 58-42.
The premier says he's never been particularly concerned with polls.
"The one thing I know ... is winning last year's premiership has never been a guide to who'll win this year's premiership," he told reporters in Sydney.
Mr O'Farrell was asked whether he thought the public was reacting to an Independent Commission Against Corruption (ICAC) hearing into former resources minister Chris Hartcher and two other government MPs, Chris Spence and Darren Webber.
He said there was a "stark difference" between corruption probes into former Labor ministers and the recent announcement of a probe into his MPs, who have now been suspended from the Liberal Party.
"All we've had announced is an ICAC inquiry off the back of a matter brought to the commission's attention by the Liberal Party," he said.
"That stands in stark contrast to the actions of (Opposition Leader) John Robertson and his colleagues who sat through years of government where there were front-page stories about alleged corruption.
"No one, including John Robertson, lifted a finger to bring those matters to ICAC's attention."
