2 Engine room (Source: AMSA, drawing no. QA11840) Built at some time in the 1930s or 1940s to house a diesel electric lighting plant for lighting the cottages. Later adapted by successive replacement of the generator sets. In 1999 the two generator sets in the building were installed. These are not associated with use of the site by lightkeepers. Timber-framed, roofed, single room building on concrete slab on ground. Roof sheeted with Super Six asbestos-cement, with matching accessory ridge, gable and vent pieces. Walls sheeted with flat Timber awning casement windows; timber framed and sheeted doors. The building does not contain any major equipment from the manned lightstation period, but does contain small remnants from that period. There is a corrugated iron rainwater tank, on a timber stand, against the northern wall of the building. One of the generator sets is in working order, the other is unserviceable following fire damage. The building is in generally sound condition. Moderately significant for reasons: The engine room demonstrates the development and operation of the lightstation, particularly the provision of electricity for radio operation and the keepers’ domestic purposes (criterion a). Provision of domestic electric lighting for lightkeepers’ quarters was a typical feature of lightstations from the 1930s (criterion d).
7 Cottage 1 Built in the late 1950s and completed by around 1960. Maintained, with minor modifications, during its service as lightkeepers’ quarters until the station was in 1987. Refurbished by the private lessee during the 2000s and currently occupied by staff of the private lessee. Timber-framed detached built on two levels stepping down the slope, connected with a single flight internal stair. Walls sheeted externally with hardwood weatherboards, internally with hardboard. Roofed with Super-Six asbestos-cement sheeting. Timber double-hung window sashes with external hinged timber cyclone shutters. The building is in generally condition. Moderately significant for these reasons: The cottage demonstrates the development of the lightstation, particularly the improvements to the keepers’ living conditions made in the 1950s (criterion a). The cottage is a characteristic element of lightstations (criterion d). 8 Workshop, store, and radio room in the late 1950s as workshop and store. Used as a radio room. Refurbished by the private lessee during the 2000s and currently used by staff of the private lessee. Timber-framed building on concrete slab on ground. Walls sheeted inside and out with flat asbestos-cement. Roofed with Super-Six asbestos-cement sheeting. Glass louvre windows, and timber framed and sheeted doors. The building is in generally sound condition. Moderately significant for these reasons: The workshop building demonstrates the development of the lightstation, particularly the improvements in radio communication made in the 1950s (criterion a). The workshop is a characteristic element of lightstations (criterion d).
9 Cottage 2 Built in the late 1950s and completed by around 1960. Maintained, with minor modifications, during its service as lightkeepers’ quarters until the station was in 1987. Refurbished by the private lessee during the 2000s and currently occupied by staff of the private lessee. Timber-framed detached single-storey house. Walls sheeted externally with hardwood weatherboards, internally with hardboard. Roofed with asbestos-cement sheeting. Timber double-hung window sashes with external hinged timber cyclone shutters. The building is in generally sound condition. Moderately significant for these reasons: The cottage demonstrates the development of the lightstation, particularly the improvements to the keepers’ living conditions made in the 1950s (criterion a). The cottage is a characteristic element of lightstations (criterion d). 10 Septic pits and absorption trench Built in the late 1950s and completed by around 1960. Currently servicing the two cottages. Underground concrete pits, pipework and transpiration trenches — two sets, one connected to each cottage. In serviceable condition. Moderately significant for this reason: The installation demonstrates the development of the lightstation, particularly the improvements to the keepers’ living conditions made in the 1950s (criterion a).
11 Concrete water tank Built in the late 1950s and completed by around 1960, to collect and store rainwater from the roofs of the buildings. Refurbished with painted waterproofing membrane in 2010. Asbestos-cement roof sheeting replaced with steel in 2010. Currently servicing the two cottages. Rectangular tank with floor and walls of reinforced concrete cast in situ. Corrugated steel skillion roof on timber frame. The tank is in generally sound condition. Moderately significant for these reasons: The tank demonstrates the development of the lightstation, particularly the improvements to the keepers’ living conditions made in the 1950s (criterion a). 12 Tramline, trolley and cables Built in the late 1950s. In service until the lightstation was de-manned in 1987. Straight run of tramline, inclined over most of its length, with a level section at the top. A wire hauling rope runs on two sets of steel rollers — one set between the rails, and one outside. The trolley runs on two pairs of wheels, and has a flat timber tray. The system is generally complete and in sound condition. Moderately significant for these reasons: The tramline and its equipment demonstrates the development and operation of the lightstation, particularly the work of transferring fuel, equipment and stores from boats (criterion a). The tramline and its associated components are typical elements of lightstations on elevated sites serviced from the sea (criterion d).
13 Metal water tank and stand Built around 1960 as a header tank to supply rainwater pumped up from the concrete tank. No longer in service. Standard type galvanised steel lattice tank stand, supporting a corrugated steel tank. The stability of the structure has not been assessed. Moderately significant for these reasons: The tank demonstrates the development of the lightstation, particularly the improvements to the keepers’ living conditions made in the (criterion a). 14 Paths, stairs and bridges (Source: AMSA, drawing no. QC12950) Paths laid out and paved at various times since 1879. Most of the paths, stairs and bridges date from the late 1950s, but the path and stairs leading down on to the boat landing are older. The timber bridges were replaced in 2010. A series of walkways and stairs of concrete cast in situ. The timber bridges are replacements of structures dating from c. 1960. The stairs and bridges are in sound condition, but do not all comply with current standards for width, stair dimensions, or grade. Moderately significant for these reasons: The paths, stairs and bridges demonstrate the development and pattern of use of the lightstation, particularly the arrangements for moving around the site and handling stores before the tramway was built (criterion a). The arrangement of paths is a characteristic element of lightstations (criterion d). 15 Polyethylene water tank New tank installed in 2010. Cylindrical polyethylene tank, capacity about 5000 L, on a ground level pad. The tank is filled by pumping water from the concrete tank, and supplies water to the two cottages. Not significant. This is a standard modern type of water tank.
