Coordinates: 33°48′36″S 151°16′24″E / 33.81000°S 151.27333°E Dobroyd Head is a point or headland in the Northern Beaches local government area, in the suburb of Balgowlah Heights, New South Wales, Australia. It is part of the Sydney Harbour National Park, which contains examples of ecosystems at risk such as coastal heath. Tania Park is located to the immediate north-east, and contains the 2MWM 90.3 transmitter. There is a lookout sited on the headland named after Arabanoo, the first Aboriginal man to live among European settlers who was captured in Manly Cove in 1788.
In January 1788 Captain Arthur Phillip noted Aboriginal people living in caves at what is now Wellings Reserve, Balgowlah Heights, and there are a number of Aboriginal sites recorded in the area, including a midden at Reef Beach, which was partly eroded by a storm in May 1974, when human remains were exposed. What is now Dobroyd Head was originally named "Dobroyd Point" (which is now the name of a locality in Haberfield in the Inner West) by Simeon Lord (1771–1840), a landowner in the district in the early 19th century. Dobroyd Castle, its namesake, was the home of his mother, Ann Fielden, prior to her marriage in 1764. On his death in 1840, he gifted the land to the Crown, with a stipulation that the name must be kept.
