After a rockstar arrival at Byron Bay Bluesfest on Sunday, Labor leader Anthony Albanese received a crowd reaction no one wants when they're on stage.

There were loud boos amongst the cheers as the opposition leader made a small address to the audience

"Anthony Albanese got a friendly reception from the crowd when he first arrived at Bluesfest," 9News political reporter Fiona Willan said.

"Not so friendly when he went on stage ... until Jimmy Barnes appeared."

There were cheers for Mr Albanese during his address when he referenced recognition of First Nations people in the constitution and called for "a government that backs the arts sector".

But the loudest cheer came from his last few words: "Ladies and gentlemen, welcome Jimmy Barnes."

Voter support for the opposition fell from 38 per cent to 34 per cent.

Two weeks ago, Mr Albanese had a slim lead over Scott Morrison as preferred prime minister, 37 per cent to 36 per cent.

But those fortunes have now been flipped, and Mr Morrison leads Mr Albanese, 38 per cent to 30 per cent.

Primary support for the Coalition rose from 34 to 35 per cent, and Mr Morrison made gains on his personal approval and performance on key issues including economic management and national security.
