There are electoral rolls, with some that have been uploaded to various commercial websites.
From the NSW ER 1913, in the electorate of MURRUMBIDGEE, and polling at North Yanko :
Eliza Selina BOTTRELL, of Leeton, domestic duties
Joseph BOTTRELL, of Leeton, engine driver. (no middle name for Joseph)
It was not compulsory to enrol, but you needed to be 21 years of age, a local resident, and a British Subject to be eligible.
