About Port Willunga

Port Willunga is a small coastal suburb on the Fleurieu Peninsula, approximately 40 kilometres south of the Adelaide CBD within the City of Onkaparinga. With a population of 1,785, it is a compact seaside community covering just 2.1 square kilometres, and has grown steadily from 1,637 residents in 2016. The suburb has a median age of 44 and a median household income of around $1,313 per week, attracting a mix of sea-change families, retirees, and holiday homeowners. The surrounding area forms part of the southern Adelaide coastal corridor, fronting the Gulf St Vincent.

Port Willunga is best known for its stunning clifftop views, white sandy beach, and the iconic ruins of the historic Star of Greece jetty — remnants of a 19th-century cargo loading pier that has become one of South Australia's most photographed landmarks. The beach is a favourite for swimming, snorkelling, and surfing, drawing visitors from across Adelaide on weekends and holidays. Nearby McLaren Vale is just a short drive inland, offering world-class wineries and restaurants that add to the region's lifestyle appeal.
