Port Noarlunga is a suburb in the City of Onkaparinga, South Australia. It is a small sea-side suburb, population 2,632, about to the south of the Adelaide city centre and was originally created as a sea port. This area is now popular as a holiday destination or for permanent residents wishing to commute to Adelaide or work locally. There is a jetty that connects to a long natural reef that is exposed at low tide. The beach is large and very long and has reasonable surfing in the South Port area whose name is taken from its location - 'South of the Port'.
