Nobbys Head Light is an active lighthouse on Nobbys Head, a headland on the south side of the entrance to Newcastle Harbour, New South Wales, Australia. It is included in Newcastle's Coat of Arms.[4]
The site and the lighthouses are managed by the Newcastle Port Corporation. They are closed to the public.
The first beacon in the area was an open coal fire set on Signal Head with a range of 7 kilometres (4.3 mi). This was changed in 1821 to a large metal device burning oil which was visible for 12 kilometres (7.5 mi), but shortly reverted to coal as the oil system was not reliable.
By 1846 Nobbys Head, originally a small islet more than 60 metres (200 ft) high, was connected to the mainland with a causeway. The island was reduced in height to improve the sailing conditions and to accommodate for a lighthouse and signal station, built in 1858. The lighthouse was designed by Alexander Dawson. The original light had an intensity of 20,000 cd and was attended by three lighthouse keepers.
In 1934 the light was electrified and automated.
The current light source is a 120 V 1000 W, quartz halogen lamp and the power source is mains electricity with a diesel generator as backup. Currently at the site are three one-story keeper's houses, a three-story signal station, and other buildings housing the port watch. The entire station is floodlit at night.
