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 St Marys, South Australia, Australia. Use the Map and Satellite buttons above to switch between street map and aerial imagery views.

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 St Marys.
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.

St Marys lies on a gentle slope, a landscape where the Adelaide Hills begin their slow, verdant rise towards the sky. It lies 8.9 km south-south-west of Adelaide, SA (from Adelaide, SA: bearing 192°T), and is situated 13.9 km north-north-east of Morphett Vale. The air here carries a faint, sweet scent of dry grass and the distant promise of sea salt, a subtle reminder of the coast’s proximity. Houses, mostly of brick and tile, scatter themselves across the terrain, their gardens a patchwork of hardy natives and cultivated blooms. The streets, lined with mature trees, offer dappled shade on warmer days, and the quiet hum of suburban life is punctuated by the occasional bird call or the rumble of a passing car. The light here, particularly in the late afternoon, has a honeyed quality, softening the edges of the world and lending a peaceful character to the neighbourhood.
This is a place with roots reaching back to the early days of South Australia's development. St Marys, part of the City of Mitcham, has seen its share of change, from its agricultural beginnings to its present-day residential character. The local economy, while now largely driven by services and retail in neighbouring centres, still echoes with the land’s past, with remnants of orchards and market gardens occasionally visible. The close connection to the natural environment is a defining feature, with many residents enjoying the accessible walking trails and the proximity to reserves that preserve the native bushland. The feeling is one of a settled community, one that appreciates the blend of suburban comfort and the enduring, subtle beauty of its geographical setting.

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 St Marys is identified even where the name is shared across multiple localities.
