"One of Burpengary’s most prominent former residents and World War I veteran, Charles Munro, was recently honoured posthumously with a parkland naming ceremony in recognition of his achievements and popularity within the local community.
Attended by approximately 50 remaining descendants, members of the public, and Councillor Peter Flannery, the new Charles Munro Reserve sign was officially unveiled on Saturday, July 24, following the Burpengary Progress Association’s successful application to council last year. The site of the reserve, on the corner of Dale Street and Susan Court, Burpengary, is nearby to where Charles Munro and his family settled on a farm soon after arriving in Australia early last century."
