(1) Where the voting day for a referendum is the same as that fixed for the polling at an election, the answers by a person claiming to vote at the referendum to the questions put under section 229 of the Commonwealth Electoral Act 1918 for the purposes of the election may, if they are satisfactory as regards the election, be accepted as sufficient to enable the person to vote at the referendum.
(2) If the presiding officer or a polling official accepts under subsection (1) the answers by a person as sufficient to enable the person to vote at a referendum, the officer or official may, if the officer or official thinks fit, put to the person questions in order to ascertain whether the person has voted before in the referendum or referendums.
(3) If the person answers so as to indicate that the person has voted before in the referendum or referendums or does not answer, the person's claim to vote must be rejected if the presiding officer is satisfied that this subsection applies.
