Острова Святого Алуарна у мыса Лиувин

Island group near Cape Leeuwin

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.

In March 1772, the crew of the French naval vessel Le Gros Ventre, commanded by Louis Aleno de St Aloüarn, became the first Europeans known to have visited the islands. A few weeks later, at Dirk Hartog Island, St Aloüarn formally claimed part of Western Australia for France. The islands were named after St Aloüarn in 1792, by Antoine d'Entrecasteaux, as the leader of a subsequent French expedition.

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.

In 2009, the gazettal of the Augusta Port Area delineated the port in reference to the northernmost point (at High water level) on Saint Alouarn Island (with truncated spelling), as well as Seal Island, and Point Matthew. In 2013 2013, the Western Australian government, through the Royalties for Regions programme, constructed a new harbour outside of the Hardy Inlet area of the Blackwood River mouth. The port is to the south, and within view of Flinders Bay settlement and boat ramp. It is located adjacent to the road that goes to Cape Leeuwin lighthouse. Oceangoing vessels had previously anchored in Flinders Bay, or used the Flinders Bay jetty; however, its short term operation between the 1890s and 1930s subsequently left the bay with no port facility.
