What do the abbreviations mean under the qualification column in the post 1920 Electoral Rolls?
The abbreviations indicate the criteria by which the voter has qualified to vote. For example, “R” indicates a Residency qualification, “O” an Occupation qualification and “NM” a “Naval or Military” qualification. The abbreviations have changed a little over time as the legislation has varied (for example, in 1928, women were given the right to vote). A definition of the meaning of the abbreviations appears on the first page of each polling district, and samples are provided via the links below.
