and blacksmith's shop of 1853. Other warehouse type structures which survive from this period include the boiler house of 1908, the engine house of 1909 and the coppersmith's shop.
3) and 4) 1913-47. Substantial built development took place during this period related to the expansion of the dockyards. Several larger scale industrial warehouse buildings were erected in the centre of the island on the site of the former Biloela Female Gaol. These buildings are primarily steel framed with corrugated galvanised iron cladding. Extant buildings of this type include the estimating and drawing offices 1915-18 and the electrical Shop 1915-16. Other buildings were constructed in the dockyards area; these appear to have been subsequently demolished with the exception of the Federation styled timber vernacular administration buildings to the south. The powerhouse of 1918 in the Federation Warehouse style is constructed of load bearing brickwork below a steeply pitched gabled roof. The powerhouse chimney remains in place. Residential buildings in the western part of the higher ground include primarily Federation style semi-detached structures executed characteristically in red brick with tiled roofs. These semis have been extended with fibro additions. A two storey semi 1913-16 to the north is more impressive in its architectural expression and features sunhoods, decorative eaves and balustrades. During the Cockatoo Docks and Engineering Phase (1933-48) numerous warehouses were built which dominate the lower levels of the island. These are predominantly steel framed and clad with corrugated iron sheeting. Other structures are related to the importance of local river traffic on the surrounding waterways; the Parramatta Wharf turnstile shelter of 1945 is one of these. The muster station of 1945 is a reminder of the post war operation of the dockyards. Other structures, including air raid shelters and administration buildings, are evidence of the importance and operation of the island during the hostilities of World War Two.
5) 1948-92. Numerous warehouses were built during this phase. Many are steel framed with corrugated iron sheeting cladding. A group of red brick warehouses with curved roofscapes were constructed primarily after World War Two. A group of international style buildings at the south-eastern corner of the dockyards forms a distinct group. Among the latter is the former weapons workshop of 1971.
In addition to the standing buildings described above the island contains numerous items of remnant equipment. Significant items include two Bellis and Morcom steam engines, lathes, planing equipment, hydraulic presses, plate bending machinery, boring machines, rivet presses, threading machinery, plate rolls, steam hammers and cutting equipment. The only building which retains its equipment intact is the powerhouse; equipment includes the dewatering system, the air compressors, the hydraulic pumps and the mercury rectifier bank used to convert AC to DC.
