Commonwealth Electoral Act 1918

A voting officer must put to each person attending before the voting officer, and claiming to vote in an election or elections (as the case requires), questions in order to ascertain:

the person’s full name; and

the person’s place of living; and

whether the person has voted before in the election or elections (as the case requires).

If the answers the voter gives to the questions under subsection (1) do not satisfy the voting officer that the applicant is a particular person on a copy of the certified list of voters, or on an approved list of voters, for a particular Division, the officer may ask the voter one or more other questions about matters shown on the list for the particular person, to establish whether the voter is that particular person.
