Port Noarlunga is a suburb in the City of Onkaparinga, South Australia. It is a small sea-side suburb, population 2,549, about 30 km to the south of Adelaide 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 leads nearly all the way to one of South Australia's few natural reefs. 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'.
The suburb is bounded to the south by the Onkaparinga River, including a tidal estuary. It is bounded to the west by the Gulf St Vincent and to the north and east by artificial boundaries.
