In December 2024, the NSW Government created the Housing Delivery Authority (HDA) to lead a new State Significant Development pathway for residential developments. The HDA is a three-person panel that evaluates proposals and makes recommendations to the minister about which proposals should be declared as State Significant Developments. The Department of Planning, Housing and Infrastructure (DPHI) supports the HDA by evaluating expressions of interest from developers. This audit will consider the effectiveness of the HDA’s governance and decision-making processes, including the role of DPHI.
