The Tomaree Head Fortifications is a heritage-listed fortification at 2 Shoal Bay Road, Shoal Bay, New South Wales, Australia. It is also known as Tomaree Head Battery, Tomaree Battery and Stephens Battery. It was added to the New South Wales State Heritage Register on 22 October 2010. History Radar at Tomaree Head Tomaree Head was one of the first sites selected in an air force project to protect Australia with a ring of radar stations around the continent. The threat of war from Japan was looming, but only three radar sets were available: the project was launched with a special survey to select three sites. Many more radar sets were needed, long range radar, for which the authorities expected a long delay, so it was essential to put the three available radar sets to work in the parts of Australia requiring them most urgently. The available radar sets were "on loan" from a CSIR facility called the Radiophysics Laboratory, British sets sent for research. The survey was led by two very senior officers: Dr David Martyn, chief of the Laboratory, and Squadron Leader A. G. Pither, the Royal Australian Air Force radar specialist. They flew over the coast from Port Kembla to Forster, selecting sites near Port Kembla, near Terrigal, and at Tomaree Head. The recommendation by the Services was to locate the "available" radar sets to protect "the vital Newcastle-Sydney-Port Kembla industrial region", which was accepted by the highest authority. Applying this priority, the survey officers used Newcastle steel works as their point of reference when deciding on Tomaree Head. Japan burst into the war before the radar building was started. The British radar set was hastily placed in a vacant bunker in Newcastle. By the time the radar building was completed on Tomaree Head, an Australian radar known as AW was available from the factory. The British set could now be removed and was sent to the place near Terrigal. The AW radar was made possible by a surprise break-through at the Radiophysics Laboratory. Dr J. H. Piddington adapted the design of a short range radar, a familiar design, producing the range necessary for air warning, no special components needed. A version called LW/AW (light weight/air warning) was acclaimed as the backbone of the RAAF radar network in the island warfare of World War 2, represented by a replica at the Australian War Memorial.
