As Mungindi, Queensland's postmaster he was not empowered to deal with letters bearing NSW stamps so he applied for, and was appointed to the position of postmaster of Mungindi, NSW in 1867. The following year there were 43 subscribers listed in the Post Office Directory for Mungindi, Qld. Very few of these were family men but the numbers explain the need for the store, which Alexander was operating at that time.
