Nobbys Head (Aboriginal: Whibayganba) is a headland located on the southern entrance to Newcastle Harbour, New South Wales, Australia. The headland is situated above the Hunter River and the Tasman Sea of the South Pacific Ocean. Originally called Coal Island, and then later Nobbys Island, the Island was connected to the mainland at first by the Macquarie Pier, completed in 1846, 38 years after commencement. The pier was eventually replaced by a breakwater. Sand accumulated along the breakwall to make Nobby's beach, and the sand and plants makes the isthmus appear natural.
