Sydney’s already pricey house-and-land packages are set to get even more expensive over the next few years unless more land is rezoned for housing, and speedily delivered over the coming years, the Urban Development Institute of Australia has warned.

The UDIA NSW’s Greenfield Land Supply Pipeline Report identified a shortfall of 20,100 housing lots by fiscal 2030 across the Sydney mega-region (an area from Illawarra-Shoalhaven to the Hunter) even if developers were able to deliver around 130,000 housing lots “programmed for delivery” over the next eight years.
