The first Post Office in Berrigan was a receiving office opened in May 1884. A once weekly mail service was provided between Corowa and Murray Hut at this time. The school teacher Miss Ruddock was the first appointed postmistress as the mail arrived at 4pm and her school duties were finished for the day by then. Mail was therefore delivered to her, at her residence, for distribution.
In the following years the Post Office had a few other homes in line with the Postmaster of the time before moving in to its own two room weatherboard building which incorporated the telegraph department in November 1891. This was not deemed to be big enough with the increase in demand for a more frequent mail service and it was decided to build an office that also would house the Postmaster.
The brick building that is still the current Post Office was built in 1901 at a cost of £1398.
