Lawrence Rocks

The Lawrence Rocks are a group of two rocky islets, 6.8 ha and 1.5 ha in area, with an associated reef, 2.4 km south-east of Point Danger in western Victoria, Australia, and about 6 km south-east of the city of Portland.[3] Geologically, the group is formed from the remnants of an extinct volcano, with the islets composed of basalt and tuff.[4]

The islets were sighted by Lieutenant James Grant on 5 December 1800 from the survey brig HMS Lady Nelson and named[1] for Captain Effingham Lawrence,[2] one of the Elder Brethren of Trinity House.

Fauna

The rocks are protected as a nature reserve and are the site of a breeding colony of Australasian gannets, the overspill from which led to the establishment of a sister colony at Point Danger.[5] The group has been identified by BirdLife International as an Important Bird Area (IBA), because it supports over 10% of the world population of Australasian gannets, being used by over 6000 birds.[6] [7] Other birds recorded on the rocks, and likely to breed there, include little penguins, black-faced cormorants, crested terns, silver gulls, sooty oystercatchers and small numbers of Cape gannets. The rocks are also used as a haul-out site by Australian fur seals.[4] Seal hunting was conducted on the island in the 19th century.[8]
