Duchess
Western Australia, Australia
PS Duchess was a popular paddle steamer ferry built in Western Australia for use on the Swan River. It was later converted into a self-propelled barge for use around Fremantle Harbour, before being scuttled near Rottnest Island; the wreck site is yet to be identified. Duchess worked for 29 years as a river ferry on the Swan River in South Perth, being the first ferry to convey passengers to Perth Zoo, a service which continues today under Transperth. As a barge it delivered materials for the construction of military fortifications on Rottnest Island.
