The lighthouse was originally gas-lit, later converted to electricity in 1956.
The bright green color is a standardized maritime signal to indicate the starboard side of a channel when entering a harbor.
It was specifically designed to be easily dismantled and moved, reflecting the evolving nature of harbor infrastructure in the early 20th century.
The cast-iron panels are bolted together, a construction technique common for Australian lighthouses of the Edwardian era.
The South Mole itself is part of the extensive harbor expansion project initiated by C.Y. O'Connor in the late 1890s.
South Mole Lighthouse is a distinctively vibrant green cast-iron beacon situated at the tip of the South Mole jetty in Fremantle, Western Australia. Constructed in 1903, the tower stands 15 meters tall and marks the southern entrance to the Fremantle Inner Harbour. It remains an active navigational aid for vessels entering the port from the Indian Ocean. The structure is characterized by its bright green paintwork, chosen to contrast with the deep blue of the ocean and the white of the North Mole Lighthouse. The jetty itself serves as a man-made breakwater extending significantly into the ocean, constructed primarily from limestone and boulders. Visitors access the lighthouse by walking the length of the exposed jetty, which offers expansive views of the coastline and maritime traffic. The site is a popular destination for locals engaged in recreational fishing and coastal observation.
From the start of the jetty looking down the full length of the path with the green tower centered at the horizon.
Wear sturdy, non-slip footwear to navigate the uneven limestone rocks and jetty surface.
Bring windproof clothing, as the exposed location experiences high winds regardless of the season.
Stay clear of the jetty edges during high swell or storm surges when waves often wash over the walkway.
Do not attempt to climb or touch the lighthouse structure as it is a working navigational aid and restricted property.
Avoid obstructing the narrow walkway for local anglers; maintain a respectful distance from fishing lines.
