NSW Opposition Leader Mark Speakman says the Minns government has conceded in this week’s state budget that it is missing its housing target, and will promise a future Liberal-led government will reduce the cost of building new homes.

Ahead of his budget reply speech on Thursday, Speakman told The Australian Financial Review he would announce fresh cost-of-living relieve measures – likely to be restoring ActiveKids vouchers – and policies to improve the financial feasibility of building.
