Explore Mount Colah, New South Wales, Australia, with this interactive street and satellite map. You can “grab” the Mount Colah, NSW 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 Mount Colah, New South Wales, 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 Mount Colah.
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.

Mount Colah rests on the undulating sandstone ridges that form the spine of the Hornsby plateau. It lies 4.1 km north-north-east of Hornsby, NSW (from Hornsby, NSW: bearing 28°T), and is situated 13.0 km north-east of Castle Hill. The air here carries the scent of eucalypt, a dry, resinous perfume that sharpens with the midday sun. Native bushland, a scrubby tapestry of wattles, banksias, and towering gum trees, spills down the slopes, its greens deepening to a bruised purple in the late afternoon light. The land itself feels ancient, worn smooth by millennia of rain and wind, its sandstone outcrops hinting at the vast geological forces that shaped this corner of New South Wales. The occasional clearing reveals glimpses of suburban rooftops, a human presence gently imposed upon the wilder contours of the terrain.
The story of Mount Colah is one of gradual settlement, following the pathways carved by explorers and later, by the very railway line that brought its modern shape into being. Once part of a broader agricultural landscape, the area’s economic life has shifted, with many residents now commuting to the wider Sydney metropolis. Yet, the echoes of its past remain; remnants of orchards and smaller farms can still be discerned in the layout of older streets. The nearby national parks, extensions of the very wilderness that defines Mount Colah, offer a constant reminder of the natural heritage that underpins the area, drawing walkers and nature lovers to its shaded trails and scenic lookouts. The quiet hum of everyday life here is punctuated by the calls of native birds and the rustle of leaves, a subtle counterpoint to the distant thrum of the city.

This page provides a street and satellite map of Mount Colah, New South Wales. Live weather conditions with current observations and a 7-day forecast are powered by Open-Meteo. Real-time local news and world news feeds keep the page current, while an editorially written description provides background on Mount Colah, in The Council Of The Shire Of Hornsby local government area.
Detailed location data for Mount Colah includes the postcode (2079), telephone area code (02), and local government area (The Council Of The Shire Of Hornsby), with an ABS remoteness classification of Major Cities of Australia. 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 Mount Colah is identified even where the name is shared across multiple localities.
