Baudin Rocks, also previously known as the Godfrey Islands, is a group of islets on the south east coast of in the Australian state of South Australia about 8.3 kilometres (5.2 miles) North-northwest of Robe. The islet group was discovered and named by Matthew Flinders in 1802 after Nicolas Baudin. The group has had protected area status since 1965 and since 1972, the group has been part of the Baudin Rocks Conservation Park.

Baudin Rocks is a group of islets on the south east coast of South Australia about 8.3 kilometres (5.2 miles) north-northwest of the town of Robe. The group consists of two major islets and at least 17 smaller islets with a total area about 5 hectares (12 acres). The maximum elevation is 12 metres (39 feet). As of 1996, the smaller northern islet is the most accessible in the group, having a sandy beach on its north-western corner.

Baudin Rocks was formed about 6000 years ago when sea levels rose at the start of the Holocene. The island group and adjoined submerged reef are composed of Bridgewater Formation calcareous sandstone. The island group is part of a submerged ridge that rises from a depth of 10 m (33 ft) within 400 m (1,300 ft) to 800 m (2,600 ft) on the group’s west side while on its east and south side while the same transition occurs over respectively distances of approximately 400 m (1,300 ft) and 1,600 m (5,200 ft).

As of 1996, the two larger islets were reported as having vegetation and this is limited to both the east-northeast and to about 50% of the total surface area of these islets. The dominant species is the low, sprawling Nitre bush. Surveys reported in both 1994 and 1996 have completely different lists of less dominant species. As of 1994, the other species included leafy sea heath, ruby saltbush, coastal lignum and leafy peppercress while the introduced African boxthorn occurred on the south islet. As of 1996, the other species present on the northern islet as of 1996 included Bower Spinach, Austral Seablite, Southern Sea-heath, a single bush of African Boxthorn and possibly Variable Groundsel. The larger south islet which had not been visited at the time of reporting in 1996 was ‘reported to have many shrubs of the native Australian Box thorn’.
