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 St Marys, New South Wales, 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 is a locality in the Penrith City Council local government area of New South Wales, Australia. The locality covers an area of 10.6 km². It lies approximately 43 km west-northwest of Sydney.

St Marys unfolds across a landscape that feels both grounded and subtly aspiring, where the rich, reddish earth of western Sydney gives way to a gentle undulation, hinting at the broader Hawkesbury-Nepean river system that lies not too far distant. It lies 9.4 km east-north-east of Glenmore Park, NSW (from Glenmore Park, NSW: bearing 60°T), and is situated 12.5 km west-north-west of Blacktown. The air here, particularly in the hushed hours before dawn, carries a clean, almost crisp quality, a refreshing counterpoint to the urban sprawl it neighbours, and the late afternoon sun often casts a warm, golden hue across the suburban streets, lending a painterly glow to the ordinary. Mature trees, remnants of older plantings, stand sentinel along footpaths and in parks, their branches reaching out with a quiet resilience, their leaves rustling with secrets whispered by the prevailing breezes.
This locality carries the echoes of a past deeply entwined with the agricultural heartland of New South Wales. Once, the land around St Marys was a vital source of produce, feeding the growing colony, and the legacy of those early farming endeavours can still be glimpsed in the enduring patterns of the terrain and the names of streets that recall its pastoral origins. The development of St Marys as a significant centre in its own right has been a story of steady growth, driven by its strategic position and its capacity to absorb and foster new industries, from manufacturing to the service sectors that now define its economic pulse. A distinctive character has emerged, a blend of established neighbourhoods and newer developments, creating a community that is both aware of its roots and forward-looking, a place where the everyday hum of life is underscored by a quiet pride in its enduring presence.

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