The Tasman Island lighthouse in south eastern Tasmania is one of the highest operating lighthouses in Australia and marks the final turning point for yachts in the Sydney-Hobart race.   The island is separated from nearby Cape Pillar by the narrow Tasman Passage, which is less than 500 metres wide.  It was one of the more isolated lightstations and for many keepers, not a popular posting.

History
Tasman Island lighthouse was the last of the manned lights to be built in Tasmania. 

A meeting of the Consolidated Marine Board in August 1885 discussed the possibility of a lighthouse in the vicinity of Cape Pillar.  After discounting the Cape itself and nearby Hippolyte Rocks, a site inspection was made to Tasman Island.  Despite a recommendation in 1886 that construction should proceed, the proposal lapsed until 1903 when approval was, at last, given.

Plans were drawn up by Huckson & Hutchison and a prefabricated cast-iron tower and 1st Order lens manufactured by Chance Brothers of Birmingham was shipped out from England.

The difficulties of working in such a precipitous location were emphasised when two members of the Marine Board fell in while attempting a landing.  Despite this, builders Henriksen & Knutsen commenced construction in January 1904.  The heavy cast-iron plates, each weighing up to 13 cwt, took up to eight hours to reach the construction site.  They were then bolted together and positioned on a concrete base 7.601 metres (24 feet 11¼ inches) in diameter.

Three keeper’s cottages were built of solid brick, with sheds for wood and coal under the same roof for protection from the wild weather. The total cost of construction was about £22,000, a considerable sum in those days.  

The first superintendent, George Johnston with Assistants J. McGuire and E. Davis arrived on Tasman Island in December 1905 and already had vegetable gardens growing by the time the light was officially opened by the Master Warden, A.E. Risby on 2nd April 1906.

There were problems with the lamp mantle which regularly fractured due to the degree of swaying at the top of the tower in strong winds.  On the night of 20th March 1907 the log reads:  The tower vibrated to such an extent that it shook the mantles to pieces;  had  to substitute the wick-burner at 2 a.m.’   During another storm in 1919, verandahs and fences were blown away, water tanks blown off their stands and out-buildings shifted off their foundations.  The winds were so strong that the vibrations in the lantern room destroyed five mantles and two pounds of mercury jumped out of the race and had to be replaced.

Once thickly forested, Tasman Island was soon almost bare.   Regularly, each Saturday, a note in station logbooks records the Assistant’s duties as ‘cutting firewood’.   As early as 1913, Station Superintendent, W. Kirkwood, thought ‘the effects of denuding the island for a fuel supply’ was perhaps the reason for severe storm damage at the lightstation.  Towards the end of the year he wrote:  Blew whole gale last night – fierce squalls, smashed up more fencing Superintendent’s quarters.’

Much of the island was grazed with flocks of up to 500 sheep, cattle, pigs and goats.  However, stock regularly disappeared down the various sink-holes and clefts on the island, never to be seen again. 

Today, the native vegetation is returning with pockets of small trees and shrubs appearing in more sheltered areas.

Weather observations were recorded in lightstation logbooks by the Head Keeper from 1906.  Official observations for the Bureau of Meteorology did not commence till 1922 when daily rainfall readings were taken, although a Bureau of Meteorology rain gauge was not provided until September 1923.  An automatic weather station (AWS) commenced operation on the island in 1991.

Access to such a remote lightstation was difficult.  Seas were frequently too rough for supply ships to approach the island.  Landings were originally made on the north-west side of the island where a track known as the Zigzag was built.  Then a landing platform was constructed on the more sheltered north-east corner of the island with a crane operated by a steam-driven donkey engine.  From there, twin trolleys were hauled, one up one down, negotiating the 1:1 slope with the aid of a Jelbart motor or alternatively a horse operating a whim.  Today, access to the island is much easier by helicopter.

Kathleen Stanley describes in her book Guiding Lights, the perilous ride onto the island via a basket suspended from a flying fox:
‘The good order of the basket in which passengers were carried ashore was the responsibility of the keepers who were well aware of the need for exemplary work in this regard.  On one occasion only has it been reported that the door failed to close – perhaps because of some slight misalignment or perhaps because the operator was over-anxious to begin the transfer.  Mrs E. Jacobs, the last passenger to embark on one hazardous trip, made the journey half in and half out of the contraption, grimly held on by one of the keepers inside.

In her nineties, Mrs Jacobs could smile at the memory but there were some tense moments at the landing-stage until she was delivered safely onto solid earth.  More amazing than her perilous journey was the fact that she, with staunch matter-of-factness, was not deterred from further rides in the basket.’

For the first 20 years pigeons provided a link with the Tasmanian mainland.  However, the birds were so well fed that they were often reluctant to leave the island!  Then in the 1930s, wireless communications were established between lightstations at Cape Bruny and Maatsuyker Island.   Later, the introduction of a radio telephone further reduced the sense of isolation.

Because of the isolation, most women left the island to give birth.  However, in 1920 Nurse Cleary attended the birth on the island of a daughter, Eileen, to Head Keeper Leslie B. Johnston and his wife, Stella. 

During the war years the job of lightkeeping was considered a reserved occupation and keepers were not permitted to enlist.  Naval personnel were stationed on the island, living in the Relief Keepers quarters.  Their leisure hours were spent in the garden which soon had a colourful array of flowers. 

In their remote location the keepers on Tasman Island were vulnerable to infections.  After a visit to Hobart by one keeper in October 1921, everyone on the station became ill.   The Head Keeper was particularly incapacitated and it was two weeks before an entry in the log book said:  All on station been very ill with ‘flue’  [sic] but are now recovering.’

Sometimes this isolation could have dire consequences.  In her book, Kathleen Stanley wrote:
‘Keepers and their families on off-shore stations were always particularly susceptible to colds and influenza since they were so isolated that they had little opportunity of acquiring immunity.

On one occasion a family with several children arrived with severe colds but no medication.  Another keeper’s wife gave them her own medication, only to see the newcomers recover and one of her own children die of respiratory failure.’

A major accident occurred in 1927.  Rigger, William Groombridge was killed and Joseph Patterson was seriously injured when a crane, being installed on the landing, collapsed without warning.  The body of the dead man was thrown into the sea and never recovered.  With no direct communication with Hobart it took until the next day to get medical help for the injured man and another day to get him to Hobart for treatment.

However, unlike many other Tasmanian lightstations, there are no European graves on the island.

For nearly 70 years the lighthouse was lit by kerosene.  The Department of Transport conducted experiments with wind-power and in 1975 a prototype was installed on Tasman Island, though still backed up by two diesel generators. 

The original lantern room, lens and clockwork mechanism were dismantled and removed when the light was automated in 1976 and the last keeper left the lightstation on 20 May 1977.  Since then the Australian Maritime Safety Authority and its contractor, Australian Maritime Systems Ltd, has maintained and serviced the light which was converted to solar power in 1991.
                                             
From 1915, management of lighthouses was transferred to the Commonwealth.  In 1980 the Tasman Island lightstation was added to the Register of the National Estate as well as the Tasmanian Heritage Register and in 2004 the lighthouse was added to the Commonwealth Heritage register.

Tasman Island is now part of the Tasman National Park.

Preservation
In the years since the automation of the lighthouse and removal of lightkeepers, the unoccupied buildings deteriorated badly.  However, with dedicated work by the volunteer group Friends of Tasman Island, this trend is now being reversed.

Today, the three light keepers’ quarters are still functional with Quarters 3 (nearest to the lighthouse) used by volunteers and Park’s staff.  Quarters 2 and Quarters 1 are also undergoing restoration.  Other timber buildings, such as the relief keeper’s cottage, originally the Clerk of Works office built in 1904, have collapsed over time.

The original lantern room is now undergoing restoration by the Friends of Tasman Island.

The original Chance Brothers 1st Order lens and clockwork mechanism is on display at the Australian National Maritime Museum at Darling Harbour in Sydney.

Friends of Tasman Island
 Formed in 2005, the Friends of Tasman Island (FoTI), a Wildcare Inc subsidiary, work in partnership with the Parks & Wildlife Service, conducting work programmes on the island about three times each year. 

They have a membership of committed volunteers and supporters who focus on the restoration of both the cultural heritage and natural environment on the island. 

Funding for these projects comes, primarily, from the sale of the Lighthouses of Tasmania series of calendars which are published each year by FoTI.  Other sources of income are from government, semi-government & industry grants.

Access:                 
  • Access by sea is very difficult.  The haulage is no longer operational and tracks up the 250 metre cliffs are overgrown.
  • A permit to land by helicopter must be obtained from the Tasmanian Parks & Wildlife Service.  
ACCOMMODATION:  No commercial accommodation available

TOURS: The Rotary Club of Tasman Peninsula conduct fund-raising helicopter flights to Tasman Island once a year.   Coinciding with the anniversary of the opening of the lighthouse, members of the public can visit the island and, in co-operation with AMSA, inspect the lighthouse and keepers’ quarters.  For further information contact johnhay@bigpond.net.au
