Palm Beach is sometimes colloquially referred to as ‘Palmy’; and is used for exterior filming of the soap opera Home and Away, as the fictional town of Summer Bay. It is also the subject of the 2019 film ‘Palm Beach‘. Despite the hefty property prices it remains a haven for a variety of artists. Writing celebrating this beach is featured in “Guide to Sydney Beaches” Meuse Press. Palm Beach housing ranges from cottages to grand estates, owned by some of the country’s most affluent people. Many affluent and famous people can also be found holidaying at Palm Beach in summer. According to the Australian Taxation Office statistics for the financial year of 2016–2017, Palm Beach and the post code of 2108 was the wealthiest suburb in Australia, with an average taxable income of AUD 230,000.
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 (330 ft) above sea level, and features an operational lighthouse. The narrow sandy isthmus or tombolo 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.
Landmarks include the Barrenjoey Lighthouse, Palm Beach-Boanbong Water Reservoir, Palm Beach-McKay Water Reservoir, Palm Beach-Squaters Lodge, Blueberry Ash, and Iluka Resort Apartments. The 2.3-kilometre (1.4 mi) long east-facing eponymous beach curves in a gentle arc between the prominent 100-metre (330 ft) high, lighthouse capped, Barrenjoey Head to the sandstone rocks of Little Head in the south, beach linking Barrenjoey to the mainland. North Palm Beach extends 1.4 kilometres (0.87 mi) south from Barrenjoey, with the northern 600 metres (2,000 ft) backed by a 200-metre (660 ft) wide densely vegetated foredune. The southern Palm Beach section includes the southern 600 metres (2,000 ft) of beach, which curves to the southeast in the southern Kiddies Corner. It receives increasing protection from Little Head with waves decreasing in height down the beach. Rips usually extend all the way to the head, though usually smaller in size, with a weak permanent rip against the southern rocks.
