Explore Lock, South Australia, Australia, with this interactive street and satellite map. You can “grab” the Lock, 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 Lock, 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.
Click ⛶ Fullscreen to expand the map to fill your screen for a larger view. To return to the normal page view, press the Escape key on your keyboard, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
Drag the map to pan to any area of South Australia or beyond. Switch to Satellite view to see high-resolution aerial photography of Lock and surrounding areas, including streets, buildings, parks and waterways.
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 Lock.
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.

Lock rests on the western edge of the Eyre Peninsula, a place where the land seems to breathe in slow, deliberate exhalations of ochre dust and pale green scrub. It lies 299.1 km west-north-west of Gawler, SA (from Gawler, SA: bearing 291°T), and is situated 73.8 km west of Cleve. The terrain here is a study in subtle contours, a gentle rolling that hints at ancient geological forces rather than dramatic upheaval, with low-lying plains punctuated by outcrops of weathered rock. The air, especially in the late afternoon, carries a dry, clean scent, tinged with the faint, almost mineral fragrance of the surrounding mallee scrub and the distant tang of the sea. Sheep graze in paddocks that stretch to the horizon, their white forms stark against the muted tones of the earth, and the vast, open sky above, a canvas that shifts from the sharp blue of midday to the bruised purples and oranges of sundown, seems to press down with an immense, quiet weight.
Historically, Lock's identity has been deeply entwined with the agricultural bounty of the region, particularly wheat and barley farming, a legacy etched into the landscape by the neat rows of crops and the stoic presence of grain silos. The town's economy, once solely reliant on the harvest, has diversified over time, with grazing still a significant contributor, and a growing appreciation for the rugged, untamed beauty of the surrounding country drawing a steady trickle of travellers. Evidence of its pioneering past can be seen in the robust, unpretentious architecture of its main street, a testament to the resilience and hard work of those who first settled this land. Lock, though small, possesses a quiet character, a sense of enduring purpose that resonates with the timeless rhythm of the seasons and the persistent, gentle hum of rural life.

Real-time local news and world news feeds keep the page current, while an editorially written description provides background on Lock, in the Dc Of Elliston local government area.

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 Lock is identified even where the name is shared across multiple localities.
