Explore Portsea, Victoria, Australia, with this interactive street and satellite map. You can “grab” the Portsea, VIC 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 Portsea, Victoria, 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 Victoria or beyond. Switch to Satellite view to see high-resolution aerial photography of Portsea 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 Portsea.
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.

Portsea, a coastal sentinel, exhales the cool, salt-laced air of the Mornington Peninsula's rugged tip. It lies 32.5 km west-south-west of Mornington, VIC (from Mornington, VIC: bearing 251°T), and is situated 11.4 km north-west of Rye. Here, the land surrenders dramatically to the sea, its gentle slopes giving way to steep cliffs that plunge towards restless surf. The beaches, a shimmering ribbon of pale gold, are often windswept, their sands strewn with kelp and the polished relics of the ocean's tireless work. Inland, hardy coastal vegetation clings to the earth, a testament to the persistent westerly winds that sculpt the landscape and carry the distant cries of gulls. The light here, especially in the late afternoon, possesses a remarkable clarity, painting the ocean in hues of sapphire and jade, and etching the gnarled branches of windswept ti-trees against a sky that seems impossibly vast.
The story of Portsea is deeply entwined with its maritime heritage, a history of defence and daring. For decades, this strategic point guarded the entrance to Port Phillip Bay, its military installations a silent, watchful presence. This legacy is still felt in the enduring character of Portsea, a place that balances the quiet hum of a holiday haven with a grounded sense of purpose. The local economy, once reliant on fishing and market gardens that coaxed produce from the rich coastal soil, now leans heavily on tourism, drawing visitors to its famed surf breaks and the serene beauty of its sheltered bays. The scent of eucalyptus mingles with the briny tang of the sea, a constant reminder of the peninsula's dual nature – a place of both wild, untamed coast and cultivated, sun-kissed vineyards.

This page provides a street and satellite map of Portsea, Victoria. 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 Portsea, in the Mornington Peninsula Shire local government area.
Detailed location data for Portsea includes the postcode (3944), telephone area code (03), and local government area (Mornington Peninsula Shire), 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 Portsea is identified even where the name is shared across multiple localities.
