Gerroa is a coastal town in the Municipality of Kiama, in the Illawarra region of New South Wales, Australia 133 kilometres south of Sydney. Nearby towns are Gerringong, Kiama and Berry.
Situated at the northern end of Seven Mile Beach and the head of Crooked River, the original village was once a retreat for various religious orders. Today it is a popular holiday town, and residence for retirees. Many houses have impressive views of the beach and Mount Coolangatta. The population was 757 according to the 2011 census, although the population swells, particularly at Easter and the Christmas−New Year break. Many holiday makers stay at the caravan park, by the Crooked River.
