various sentences ended up at Cockatoo Island, it was established specifically as, and primarily was a place of secondary punishment for re-offending convicts.
Cockatoo Island critically represents the principal characteristics of a dual use convict site, one that both incarcerates convicts and provides them with hard labour.
The values expressed at Cockatoo Island are important for their ability to demonstrate the function, planning layout and architectural idiom and principal characteristics of an imperial convict public works establishment of the 1840s; and the functions, planning layout and architectural idiom and principal characteristics of a range of structures and facilities associated with the development and processes of the dockyard and shipbuilding industry over a period of 134 years.
Description:
In its original state it was 12.9 hectares in size, however it has been expanded to 17.9 hectares through cutting, filling and reclamation. Almost all of the original vegetation of the island has been removed, and the current vegetation includes plants growing on the quarried cliff faces and planting of exotic species in the garden areas. Its landscape is articulated by man made cliffs, stone walls and steps, docks, cranes, slipways and built forms (GAO CMP:2005:p2).
Cockatoo Island consists of a sandstone plateau up to 79 feet (24 metres) above water level that has been gradually reduced from its original extent by quarrying for sandstone building blocks and excavation for docks and buildings. Spoil from these activities over time has been used to help create the surrounding flat apron areas.
The plateau area can be divided into three main areas dictated by the convict era layout. The western end comprises the prisoners barracks and hospital (1839-42) form three sides of an open courtyard with the mess hall (1847-51) comprising the fourth side. West of the barracks a formal lawn encloses the roofless military guard house (1842), and the military officers' quarters (1845-57).
The central part has the two Free Overseers Quarters and evidence of the Prison Quarry area. The latter has been built over by a group of six large dockyard buildings. The Electrical shop is built in the area excavated for the water cisterns. These large buildings plus two concrete elevated water tanks are part of the island's distinctive silhouette.
The eastern end of the plateau is the residential area comprising the remaining convict era structures; the Superintendent's residence substantially enlarged in 1860, and the Clerk of Petty Sessions residence adjacent to Biloela house. A second free overseers quarters was converted to an air raid shelter in 1942. The rock hewn silos are visible only as covers at ground level and two half silos are exposed from prior quarrying. The symmetrical silos are bottle shaped, and an incision on the surface of
