Explore O'Sullivan Beach, South Australia, Australia, with this interactive street and satellite map. You can “grab” the O'Sullivan Beach, SA map and move it around to re-centre it. You can change between standard map view and satellite map view by clicking the small square in the bottom left-hand corner of the map. You can use the zoom buttons on the lower right side of the map to zoom in or out to street-level detail.
This page also offers TOPO MAPS — Geoscience Australia topographic mapping and the classic NATMAP 1:250 000 sheets — plus a labelled MGA grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below. You will find live weather, local and world news further down the page.
This interactive map shows the street layout and satellite imagery for O'Sullivan Beach, South Australia, Australia. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture to zoom in and out.

TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the Geoscience Australia National Base Map — seamless topographic mapping covering the mainland, Tasmania and the external territories. NATMAP 250K shows the classic NATMAP 1:250 000 map sheets, mosaicked nationwide — the printed sheets generations of Australians navigated the outback with. The search box finds any Australian town, suburb or landmark by name, so you are not limited to O'Sullivan Beach.
Reading the map like a paper sheet. Click Grid to overlay the Map Grid of Australia (MGA), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as an MGA grid reference as well as plain latitude and longitude — the grid reference being what emergency services and search and rescue work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need mobile coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load, which across much of inland Australia is most of the time.
Map search is available for a limited number of queries per session to manage costs. Be specific — search precisely for best results.

O'Sullivan Beach unfurls along the gentle curve of the Gulf St Vincent, a coastal fringe where the sea breeze carries the faint, briny scent of receding tides. It lies 4.7 km west of Morphett Vale, SA (from Morphett Vale, SA: bearing 268°T), and is situated 6.0 km south-south-west of Hallett Cove. The sand, a pale, sun-bleached gold, stretches in a broad, inviting sweep, meeting a sea that can range from a placid, shimmering turquoise to a restless, slate-grey depending on the mood of the southern ocean. Low-lying dunes, tufted with hardy coastal grasses and the occasional hardy shrub, form a natural boundary, their sandy contours whispering of wind and water. Inland, the landscape transitions subtly to flatter terrain, dotted with suburban developments that gradually give way to more open spaces, hinting at the agricultural lands that lie further afield. The quality of light here, particularly as the afternoon wanes, paints the sky in hues of soft rose and lavender, reflecting briefly on the wet sand left by the retreating waves.
Historically, the lands surrounding O'Sullivan Beach were part of a broader agricultural and pastoral region, their development shaped by the proximity to the coast and the fertile soils of the Adelaide Plains. The local economy has always been intrinsically linked to the sea, with fishing a traditional pursuit that continues to hold a place in the community's identity, though its scale has shifted over time. More recently, O'Sullivan Beach has become a popular residential enclave within the City of Onkaparinga, attracting families and retirees drawn by its coastal lifestyle and the relative affordability compared to more established seaside suburbs. While it doesn't boast grand historical landmarks, its character lies in the everyday rhythm of beachside living – the early morning dog walkers, the weekend surfers testing the waves, and the quiet hum of suburban life against the enduring backdrop of the ocean.

These are among the most commonly searched location details for any Australian city, town or locality.
Search Maps opens a second, independent map. It searches OpenStreetMap for any Australian town, suburb or landmark by name; offers Geoscience Australia topographic mapping and the classic NATMAP 1:250 000 sheets as base layers; overlays a labelled Map Grid of Australia (MGA) so the map can be read like a printed topographic sheet; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as an MGA grid reference and as latitude and longitude. Map tiles require mobile coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from Geoscape Administrative Boundaries (GDA2020) and enriched with GeoNames and Australian Bureau of Statistics data, matched by coordinate proximity — ensuring the correct O'Sullivan Beach is identified even where the name is shared across multiple localities.
