Sea Hill Light

The need for a lighthouse at this location was identified in 1864.[5] The first lighthouse, constructed in 1873[1] or 1876,[2][6] was the first in Queensland of its design, made of a hardwood frame clad with corrugated iron. This design was then used in seven more lighthouses, by order of establishment, Grassy Hill Light, Goods Island Light, Bay Rock Light, Old Caloundra Light, North Point Hummock Light (demolished), Gatcombe Head Light (demolished) and Bulwer Island Light.[4] With the installation of the second lighthouse in 1895 it became the front light in the range.[7] In the 1920s, the lighthouse was relocated to Station Point, about 6 kilometres (3.7 mi) northeast. It stood there until it was deactivated in the 1960s and then sold into private hands. It is currently on display at the Gladstone Maritime Museum at 23°50′4″S 151°15′37″E.[2]

The lighthouse is rather short, only 20 feet (6.1 m) in height. Unlike the other seven Queensland lighthouse towers of the corrugated iron clad type, it is hexagonal in plan, rather than round. A gallery and a lantern top the tower, and much like other Queensland lighthouses, it is painted white with a red dome.[2]

Plans for the second Sea Hill lighthouse, 1895

The second Sea Hill Lighthouse which still stands on its original site

The second lighthouse was constructed in 1895 and for a while served as the rear light in the range.[7] It is a 12-metre-high (39 ft),[8] timber framed zinc-annealed,[3] corrugated iron clad tower, with a lantern and a balcony. The original optical apparatus was a 4th order fixed lens with kerosene wick burner. In 1930 the light was converted to an open flame acetylene gas burner, with sun valve and flasher, which operated at least until 1975.[3] By 1977 the original lens had been removed and a solar powered Tideland ML-300 electric beacon installed. A pilot station was established on the foreshore nearby in 1919 and was closed in 1963.[2]

The current state of the lighthouse is unclear. There are reports that the lighthouse was deactivated in 2006.[9] While there were reports that it was demolished in early 2009, other reported that it was standing in 2014.[2] The 2018 List of Lights lists a light at the location, 39-foot-high (12 m) with a focal plane of 109 feet (33 m), displaying a light characteristic of two white flashes every six seconds (Fl.(2)W. 6s).[10]
