Palm Beach is a northern beachside suburb of Sydney, in the state of New South Wales, Australia. Palm Beach is located 41 kilometres north of the Sydney central business district, in the local government area of Pittwater Council, in the Northern Beaches region. Palm Beach sits on a peninsula at the end of Barrenjoey Road, between Pittwater and Broken Bay. Palm Beach is sometimes colloquially referred to as 'Palmy'. Palm Beach is used for exterior filming of soap opera Home and Away, as the fictional town of Summer Bay.
Palm Beach is bounded by Broken Bay to the north, the Tasman Sea (within the South Pacific Ocean) to the east, Whale Beach, Avalon and Clareville to the south, and Pittwater to the west. Barrenjoey Headland, which is in the north of the suburb, is part of Ku-ring-gai Chase National Park. The headland at the northernmost point rises quite sharply from the beach to over 100 metres above sea level, and features an operational lighthouse. The narrow sand spit linking the south side of the headland to the rest of Palm beach had extensive fencing and shrub planting undertaken during the 1980s to combat sand erosion.
