 With over 350 workers and their families already in the growing village, the lack of a post office or telegraph office was a great inconvenience to the residents.To alleviate this issue, and to provide the residents with a reliable postal service, Wyangala Dam Post Office was opened on 14 March 1929.The newly opened post office stamped mail with a "Type 2C" postmark, which had a full stop after the ‘W’ of ‘N.S.W.’.
