About Coasters Retreat

Coasters Retreat is a tiny, road-inaccessible waterside settlement in northern Sydney within Ku-ring-gai Chase National Park. The 2021 Census population is 30, making it one of the smallest residential communities in metropolitan Sydney. It sits on the western shore of Pittwater and is surrounded by bushland and protected park environments. The locality has a unique low-impact, retreat-style character with strong heritage and environmental values.

Lifestyle in Coasters Retreat is defined by boating access, beach and bush settings, and close proximity to Aboriginal heritage sites and national park trails. There are no conventional road links, so residents and visitors depend on ferries and private watercraft from Palm Beach and nearby wharves. Day-to-day services are accessed in mainland centres, requiring planned travel. The area appeals to people seeking a highly secluded coastal-bush lifestyle with minimal urban infrastructure.

Coasters Retreat falls under postcode 2108 and is governed by the Northern Beaches Council (Local Government Area). For federal elections, residents vote in the electorate of Mackellar, while state elections fall under the Pittwater electorate.
