Mt. Gambier Radio (VIY)

Its original function was to act as a relay station between Melbourne and Adelaide, operating when daylight conditions could cause problems for long distance transmission.

The buildings were double stone structures, each comprising two main rooms: one for radio equipment and an office, the other for power plant.

During World War I, Mt Gambier operated as a continuous watch station, the number of staff was increased, and the station put under guard by the local militia.

When the war ended, staff numbers declined. The station soon became a one man operation, working seven hours a day and four hours on Saturday mornings.

With the installation of more sophisticated equipment at Adelaide and Melbourne, the Mt Gambier station closed in 1920.
