St Alouarn Islands are a group of islands and rocks south-east of Cape Leeuwin in Western Australia, approximately 11 km south of Augusta in Flinders Bay. History In 1772 Louis de St Alouarn in the Le Gros Ventre was in the region as part of the expedition of Kerguelen, and subsequently the islands were named in 1792, after Captain de St Alouarn, by French navigator Antoine d'Entrecasteaux. Location The Point Matthew lookout on the road between Augusta and Cape Leeuwin, that has the islands identified in a brass compass plate that also identifies distances. Wrecks There are a number of wrecks in the vicinity of Cape Leeuwin. The best-known wreck near the islands was that of the Aberdeen White Star ship SS Pericles on an uncharted rock on 13 March 1910, within sight of the Cape Leeuwin Lighthouse in daylight hours. Whale watching boats leaving from Augusta Port tend not to venture into this group of islands and rocks, but travel around Flinders Bay to the east of the islands. The islands are significant for their bird colonies - with Seal Island and St Alouarn Island being reserves for that purpose.
