Kapunda

The Telegraph Office was opened in 1859. Soon after opening, the Admella was wrecked nearby with heavy loss of life. The South Australian Advertiser of 24 August 1859 reported that, "at a public meeting in Crase's Assembly Room in Kapunda, the Chairman was sure, before the meeting separated, the (200 people in attendance) would join with him in a vote of thanks to Mr. Darwin, Manager of the Telegraph Office there, for his attention during the previous exciting week in publishing the telegrams relative to the wreck of the Admella; which motion was carried unanimously".

From 1 October 1859, Mr. Darwin had responsibility for both the Telegraph Office and the Post Office. By 1863, Mr Darwin was fully aware of the often incorrect complaints made by a minority of customers. In 1865, he was embroiled in an important legal discussion, also involving Charles Todd, about the legal status of telegrams and who was the actual custodian of them.

Soon after, the South Australian Register reported, on 30 August 1865, that "Mr. V. H. Darwin, Postmaster and Telegraph Officer at Kapunda, met with a very serious accident on the 29th, by a fall from his horse. He was found near the main street in an unconscious state and bleeding profusely from the ears. The fall has occasioned concussion of the brain and it is feared more serious injury to the head".

Mr Darwin clearly recuperated fully because, in the Kapunda Herald of 20 April 1866, there was a long editorial seeking mentioning his good work and calling for "a really good capricious Post-Office, as well as a good telegraphic station, with an ample staff in each, but being quite independent one another (because) the postal and telegraphic services to and from Kapunda are both amongst the most remunerative of their kind and, with the prospects of a still further extension of trade, which has caused two additional Banks to be started there, it is morally certain that the business of these offices will continue steadily ...".

On 29 June 1866, Mr Darwim was elected to Secretary of the Kapunda Institute.

Amounts of £1,000 were placed on the estimates in 1866 and 1867 for the erection of a new Post and Telegraph Office.

In July 1870, many people from the surrounding district attended the monthly sale. It was reported that "everyone was delighted to see the Post & Telegraph Office well-lit with gas for the first time".

In the Assembly on 19 July 1861, the Treasurer responded to a question about a petition to amalgamate Telegraph Offices and Post Offices. He said: " there were two petitions in reference to the subject, which he should now lay upon the table of the House for the information of Hon. members. One was in favor of the amalgamation and the other against it, and he might just remark that the petitions were from the Burra, and were both signed by almost the same persons".
