The jockeying for disgraced former Labor senator Sam Dastyari's upper house seat continues with a union calling for fresh blood instead of former NSW Premier Kristina Keneally.
Ms Keneally is yet to show her hand after her unsuccessful tilt at last year's by-election for the Sydney seat of Bennelong.
Labor frontbencher Mark Butler said it was a matter for Ms Keneally.
"I'd like to see her in the federal parliament," he told ABC Radio, adding she had an enormous capacity to contribute.NSW Health Services Union secretary Gerard Hayes is keen for fresh blood rather than Ms Keneally, The Australian reports.
Transport Workers Union National Secretary Tony Sheldon is also expected to put his hand up.
Mr Dastyari announced he was quitting politics late last year amid scrutiny of his dealings with a Chinese businessman and political donor.
