It maintains 4 km of waterfront real estate in the foreshore area including Darling Harbour and The Rocks, New South Wales The Rocks . The current president of the SHFA board is Jarrod Ingram. The Sydney Harbour Foreshore Authority also owns and maintains other land in Sydney, including the Rozelle classification yard Marshalling Yard s and White Bay Power Station, New South Wales White Bay Power Station . Some of this land is not waterfront land, and it is quite a quirk of SHFA s history that it is the owner of this land.
