Hamelin Bay, Western Australia
Hamelin Bay is a bay and a locality on the south-west coast of Western Australia between Cape Leeuwin and Cape Naturaliste. It is named after French explorer Jacques Félix Emmanuel Hamelin who sailed through the area in about 1801. It is south of Cape Freycinet.
To the north, the beach leads to the Boranup Sand Patch and further to the mouth of the Margaret River, while south leads to Cape Leeuwin. The nearest locality to the east is Karridale on the Margaret River to Augusta road.
It was also a small settlement and port in Western Australia on the coast of the Leeuwin-Naturaliste Ridge which was established to service the timber milling operations of M. C. Davies. One of the Davies timber railways extended onto the Hamelin Bay Jetty, which was built in 1882 and extended in 1898. Only a few piles of the original jetty remain on site.
Although most of the adjacent land is now vested in the Leeuwin-Naturaliste National Park, small amounts of land nearby are freehold. In the 1950s the local camping area utilised the shells of a large number of decommissioned Perth Trams. None remain, and in addition to unpowered and powered camp sites there are now a small number of onsite cabins and a handful of chalets with modern facilities. A number of camp sites have been removed to accommodate these structures. A shop, and ablutions are located within the Camping Area.
Due to the nature of the Camping Area and the local weather conditions there are frequently total fire bans in the camping area.
Hamelin Bay was notorious for wrecks occurring during bad weather – its exposure to prevailing weather making it a dangerous location for anchoring or mooring.
Some fishing boats utilise the anchorage when prevailing weather is not a problem. The Maritime Museum of Western Australia's database of wrecks  includes numerous vessels which foundered in or near Hamelin Bay. An anchor from one of the wrecks was retrieved and is now situated in the beach car park at Hamelin Bay. The storm of 22 July 1900 took more than are listed below.
