Hamelin Island lies north of Cape Hamelin, just out to sea from the former Hamelin Bay Jetty, on Hamelin Bay, on the south west coast of Western Australia, about 7 km north of Cape Leeuwin.
The location of the island, and its protection of part of the anchorage from prevailing weather and winds was observed very early in the twentieth century.
