About Marion Bay

Marion Bay is a small coastal locality on the southern tip of the Yorke Peninsula in South Australia, approximately 151 kilometres south-west of Adelaide within the Yorke Peninsula Council area. With a population of around 210 residents, it is a quiet, primarily holiday-oriented community set beside a sheltered bay on the western shore of the Investigator Strait. The median household income is modest, reflecting its character as a place of semi-permanent and seasonal residents rather than a major urban centre.

The locality is best known for its scenic beach, historic jetty, and proximity to the Innes National Park, which offers dramatic clifftop views, surf breaks, snorkelling, and abundant birdlife. Fishing and water sports are central to local life, and the area draws campers and holidaymakers year-round. Facilities are minimal — a general store and campground serve residents and visitors — making a car essential and reinforcing the remote, nature-focused lifestyle that defines Marion Bay.

Marion Bay falls under postcode 5575 and is governed by the Yorke Peninsula Council (Local Government Area). For federal elections, residents vote in the electorate of Grey, while state elections fall under the Narungga electorate.
