Cape Borda is a headland located on the north west tip of Kangaroo Island in South Australia about 70 km (43 mi) west of the town of Kingscote. It was named after Jean-Charles de Borda (1733-1799), the French mathematician, physicist, naturalist and sailor, by the Baudin expedition to Australia during January 1803. It has been the site of an operating lighthouse since 1858 and is currently located within the Flinders Chase National Park.

Cape Borda is located about 70 kilometres (43 mi) west of Kingscote. It is the most north westerly point of the Kangaroo Island coast. It is the termination for a pair of coastlines - the western coastline extending from Cape du Couedic in the south and the northern coastline extending from Point Marsden in the east. It is described as ‘a bold cliffy headland, 61 metres (200 ft) high’ with ‘the upper half of the cliff is formed of white limestone, and the lower half is very dark volcanic rock’ and that ‘the hills at the cape rise to a height of more than 152 metres (499 ft) and are covered with small scrub.’

Formation, geology & oceanographyEdit

Cape Borda was formed when the sea reached its present level 7,500 years ago after sea levels started to rise at the start of the Holocene. The cliff line which includes Cape Borda consists of base strata of a metasandstone belonging to the Kanmantoo group bedrock such as Middleton Sandstone and Balquhidder Formation, overlaid by a relatively thick capping of Bridgewater Formation calcarenite rock. The water adjoining the cliff face at Cape Borda drops to depths ranging between 20 metres (66 ft) to 30 metres (98 ft).

Aboriginal useEdit

By 1999, the literature had not cited any archaeological discoveries specific to Aboriginal use of land in the immediate vicinity of Cape Borda.

European discoveryEdit

Cape Borda was named in January 1803 by the Baudin expedition of 1800-03 in the memory of Jean-Charles de Borda (1733-1799), the French mathematician, physicist, naturalist and sailor.

The lighthouse at Cape Borda was the third of three provided for by legislation; the others being erected at Cape Willoughby and Troubridge Shoals (now called Troubridge Island). The light was officially lit on 13 July 1858 and was named the ‘Flinders Light’ in August 1858 in memory of Matthew Flinders.


The coast near the Cape Borda lighthouse previously supported colonies of little penguins which are now believed to be extinct. Causes for local extinction are likely to include (but not be limited to) predation by increasing New Zealand fur seal populations and changes in prey availability.

Protected area statusEdit

Cape Borda is currently located within the protected area known as the Flinders Chase National Park. As of 2012, the waters surrounding its shores are part of a sanctuary zone located within the boundaries of the Western Kangaroo Island Marine Park.
