TypeIslandDetailsPeat Island is in the Hawkesbury towards the eastern shore and upstream of the freeway bridge. Formerly known as Rabbit Island because its shape is said to resemble a rabbit. The first use of the current name appears to have been in 1936. George Peat was granted land nearby in 1831. The island was linked to the mainland by a causeway in the early 1950s. It appears as Rabbit Island or Goat Island on a Lands Department map of 1898. CreatorPowell, John P. 1994, Placenames of the Greater Hawksbury Region, Hawkesbury River Enterprises, Berowra, pp.91-92
