Design and construction
Lighthouse design and construction had to be adapted to the particular environments in which they were built - some of which are the most rugged and remote coasts of Australia.
Building materials varied from locally quarried granite, sandstone and limestone, as well as concrete. Where local materials were unsuitable, pre-fabricated iron lattice work, timber, concrete materials and galvanised iron were used.
After the new Commonwealth took control of maritime navigation, and eventually the care and control of all Australian lighthouses between 1912 and 1915, lighthouse design became more standardised.
Early New South Wales lighthouses - designed by the Colonial Architect
Lighthouse structures in colonial NSW were unique in that many of them were architect designed, and are easily recognisable as being designed by James Barnet, NSW Colonial Architect from 1865 to 1890. It was part of Barnet's vision to create a highway of lights along the coastline from Melbourne to Sydney.
Barnet's designs include the Montague Island tower (opened 1881), constructed from granite, the Green Cape Lighthouse (1883), whose tower has a square base merging into an octagonal form, and the Smoky Cape Lighthouse, also with an unusual octagonal tower. Smoky Cape is regarded as one of the last lighthouses to be designed for architectural excellence.
The absence of suitable building materials meant that lighthouses were often built with other suitable materials that were prefabricated and shipped to the site.
For example, the Chance Brothers of Birmingham designed and prefabricated an iron structure for the Currie Harbour Light, Tasmania (1880), when no local suitable stone could be found.
The tropical heat meant that the Cape Don Lighthouse tower, located in the Coburg Peninsular (Northern Territory) could not use iron for its construction. At the same time, the local ironstone rock was not suitable for the formation of concrete, so the lighthouse was built, in 1915, from reinforced concrete using materials shipped from Melbourne.
Keepers duties: lights, bells, canons, weather and tide records
In the past, the lighthouses were required to be run by keepers. Personal aptitude was important if keepers were to cope with life in isolation. Sometimes keepers had a probationary posting year to find out how they coped with the life and the duties involved. For example, the keepers destined for Cape Jaffa (SA) and other remote outposts were usually posted to Kingston Lightstation for a year.
The main duties of lighthouse keepers included warning ships by lighting the light when fog came up, as well as ringing bells every hour or shooting cannons. Lenses had to be cleaned, gas cylinders changed, clockwork mechanisms wound and later, generators maintained.
At Moreton Bay Pile Light, Queensland, a second function of the keepers was to keep the tide records and signal the state of the tides to the passing ships.
Lighthouse keepers also had to keep watch for any suspicious vessels. At the time of the Crimean War 1853-6 (during the Gold Rush) when there was a fear of a Russian invasion with her Pacific Fleet, fortifications of several beacons were made to prepare Port Phillip Bay and Sydney Harbour against any invasion from the sea. In 1854, a cannon was placed below the South Head Signal Station to alert the Colony should the Russian Fleet arrive at Sydney Heads. Lighthouse keepers had responsibility for the canon.
