A proposal to waive stamp duty for more first home buyers in NSW has been criticised for not applying to the average home on Sydney's outskirts.
Labor on Monday said it would expand the existing government program that offers full or partial rebates on new or existing properties for first home buyers.
House prices across Sydney are predicted to drop by 12 per cent in the coming year but the number of approvals for first home buyers has halved over the last two years, Opposition leader Chris Minns said.
