The Barangaroo Delivery Authority proposed to make a regulation under the Barangaroo Delivery Authority Act 2009. The making of the regulation produced a number of social and economic benefits and costs to government and the community. The NSW Subordinate Legislation Act 1989 therefore provides for the preparation of a Regulatory Impact Statement (RIS) prior to making the regulation. A RIS is an assessment of all social and economic costs and benefits relating to the proposed regulation and other possible options to ensure that the approved regulation is the preferred course of action in achieving the policy objectives. The RIS was prepared in accordance with theSubordinate Legislation Act 1989 and has followed the requirements of the Better Regulation Office (BRO) Better Regulation Statement. The RIS will be finalised after consideration of feedback received following exhibition of the draft. Cost benefit analysis of regulatory options was completed using the NSW Government Guidelines for Economic Appraisal prepared by the NSW Treasury. The RIS was completed by Michael Clarke in close consultation with the Barangaroo Delivery Authority.
