Modern communication tecnology arrived on Gabo Island with the construction of the telegraph line from Eden to Gabo Island in 1870. These and other cylindricial insulators were associated with the original 1870 copper wire telegraph line and later the P.M.G. line. The items of telegraphic equipment comprise a number of ceramic and glass insulators of varying age and type. Two bell-shaped insulators are made of clear glass, one with remains of wooden dowel inside. In addition to insulators, there is a telephone insulator bracket made of metal with wooden pins. It was once attached to the top of a steel pole and some of theseremain in situ along the former telegraph line. Telegraphic communication commenced at the Gabo Lightstation in 1870, just eight years after the lightstation opened.The line from Sydney reached Eden, NSW by 1868 and was then extended to Gabo with the costs shared equally by NSW and Victoria. It was initially carried on posts across the sea to the island but was changed to a line along the seabed after the posts were washed away. The first telegraph office was a timber building on east side of the assistants’ quarters. In 1887 a new concrete telegraph office was built which included quarters for the operator, with Victoria and NSW sharing the construction costs. The 1992 CMP identified remnants of the line from its various phases of operation,231 and these can still be seen in 2016. Other ceramic insulators in the collection are associated with lines supported on utility poles for the transmission of high voltage electricity. The various insulators have second level significance for their historic value and provenance1. Clear glass insulator. Cyndrical bottle shape with smaller dome -like knob on top.

It is ceramic with a clear glaze.
