Victorian Premier Ted Baillieu has defended the government's performance after his personal rating dived in the latest opinion poll.

Mr Baillieu's personal rating has slumped 11 points since October, according to the latest Newspoll published in The Australian newspaper on Monday.

Forty-one per cent of voters said they were satisfied with the premier's performance, compared to 52 per cent in October.

On a two-party preferred basis, 53 per cent of voters support the coalition compared with 47 per cent preferring Labor.

Mr Baillieu said the public understood the government had tough challenges ahead.

'We have got an agenda in front of us and the community know that,' he told reporters in Melbourne on Tuesday.

'These are tough times, we've got some challenges in front of us, we are getting on with the job.'

When pressed on whether he would change his own leadership style, Mr Baillieu replied: 'We are getting on with the job.'
