NSW Labor leader Michael Daley will direct the Greater Sydney Commission to revise "unfair" housing supply targets across the city if he's elected premier.
Labor claims Western Sydney is bearing the brunt of "rampant" residential development while blue ribbon suburbs are not allocated their fair share.
"It's not fair to exempt some areas from taking on their fair share while allowing other communities to get clobbered," Mr Daley said in a release on Saturday.
Labor says the commission's plans show Hunters Hill is expected to take 150 new dwellings over five years, Mosman and Woollahra 300 dwellings and Willoughby 1,250 dwellings.
Meanwhile, Blacktown has a target of 13,950, Canterbury-Bankstown 13,250 dwellings and Parramatta 21,650 dwellings.
But Gladys Berejiklian questioned whether Mr Daley wanted to go back to the "old way" where "Labor politicians sat around a table and decided what happened where".
The premier told reporters on Saturday that she was "incredibly" pleased with the commission's work.
"Because of the great work they've done - they're an independent body - we are now looking at building a brand-new city outside the new airport at Badgerys Creek," she said in Sydney.
"That's going to bring jobs, train lines, road networks to Greater Western Sydney, the likes of which has not been seen before."
