• Explore the man-made island at South Channel Fort on one of RedBoats’ immersive island tour experiences departing from Portsea or Queenscliff.

    Strategically placed to illuminate and guard the shipping channel to Port Phillip, this significant historical site boasts panoramic views of the coastline of the Mornington Peninsula, all the way to Point Nepean, as well as Queenscliff Lighthouse.
    On a clear day, Melbourne’s skyline is visible to the north. 

    Built during the 1880s of bluestone boulders, cement and sand, South Channel Fort can only be reached by boat and is part of the Point Nepean National Park.

  • Immersive Walking Tours

    Our knowledgeable staff lead walking tours around the island. After viewing the disappearing gun emplacements of the fortification and learning about the strategic importance of the military facility, the adventure continues underground.

    As a Parks Victoria Licensed Tour Operator, we are able to lead guided tours into the keep and explore the labyrinth of underground passages where over 100 soldiers at a time would live while manning the fort at the end of the 19th century.

    The history of the fort ties into the history of Port Philip Bay and the development of the cities of Melbourne and Geelong.

  • Wildlife

    South Channel Island is not only rich in historical significance but is also one of the most important wildlife habitats on the bay. While walking along the jetty, don’t be surprised to see Australian Fur Seals and Rays swimming past beneath the surface.
    On the face of the fortress, you will find a colony of White-faced Storm Petrels. These endangered birds nest in small burrows underground at South Channel Fort, which is one of only three nesting sites for the species in Victoria.

    The Little Penguins of Port Philip Bay often nest on the island as well.

  • Diving Experiences

    The harbour at South Channel Fort provides a great opportunity for a scuba dive experience or snorkelling activity, so hop on a RedBoats South Channel Fort Diving Tour to get up close with the marine wildlife, and see what lies beneath the surface at South Channel Island.
