Cronulla is a beachside suburb, in Sydney, in the state of New South Wales, Australia. Cronulla is located 26 kilometres south of the Sydney central business district, in the local government area of the Sutherland Shire.
Cronulla is located on a peninsula framed by Botany Bay to the north, Bate Bay to the east, Port Hacking to the south, and Gunnamatta Bay to the west. The neighbouring suburb of Woolooware lies to the west of Cronulla, and Burraneer lies to the southwest. The Kurnell peninsula, the site of the first landfall on the eastern coastline made by Lt. (later Captain) James Cook in 1770, is reached by driving northeast out of Cronulla on Captain Cook Drive.
