NSW Labor leader Michael Daley has doubled down on his threat to sack the Sydney Cricket Ground Trust's board, saying he does not care if he makes "powerful" enemies and his "21st century" board would have more women.

In a fiery exchange with influential broadcaster Alan Jones on 2GB on Tuesday, Mr Daley said if Labor wins he would sack the majority of the prestigious board, including Jones, because it had "colluded" with the Berejiklian government to fund the $730 million rebuild of Allianz Stadium.

"My board will be representative of modern day society and they won't be engaging in this sort of cloak and dagger we've seen with this board," he said later at a press conference.

"When I look at the board there are two women out of 13 and that's not acceptable."
