Crane C300 adjacent to Slipway 1 on the north side of Cockatoo Island. The model is accurate to less than 50mm (2"). Cockatoo Island is the biggest island in Sydney Harbour. In the past it was used as a prison, industrial school and shipyard. The first dry dock was built by convicts and completed in 1857. The shipyard ceased operation in 1992 and the island was added to the World Heritage List in July 2010. It is currently one of the sites used by the Biennale of Sydney, a contemporary visual arts event held every two years. Modelled by Peter Olsen, Brighton-le-Sands, Sydney, Australia.
