Electoral Rolls within Australia play a vital role in a number of types of research including the study of genealogy. Historical rolls provide an insight and a certainty as to where an ancestor was located at a given point in time. Whilst many of these records are visible within libraries in Microfiche formats, a number have also been transcribed and are available via an online database search. Current records are also available and can be useful for skip tracing and finding people. As voting is mandatory and there is a requirement to be registered, the vast majority of Australians are on the electoral roll and these are available for public viewing.
