REFERENDUM (MACHINERY PROVISIONS) ACT 1984 – SECT 45
Compulsory voting
(1) It is the duty of every elector to vote at a referendum.
(2) The Electoral Commissioner must, after the voting day at a referendum, being a referendum the voting day for which was not the same as that fixed for the polling at a Senate election or a general election of members of the House of Representatives, prepare for each Division a list of the names and addresses of the electors who appear to have failed to vote at the referendum.

(a) send a penalty notice by post; or
(b) arrange for a penalty notice to be delivered by other means;
to the latest known address of each elector whose name appears on the list prepared under subsection (2).
(4) The DRO is not required to send or deliver a penalty notice if he or she is satisfied that the elector:
(a) is dead; or
(b) was absent from Australia on the voting day for the referendum; or
(c) was ineligible to vote at the referendum; or
(d) had a valid and sufficient reason for failing to vote.
The “elector” addressed in that correspondence… is it addressed to Joseph BLOGGS, BLOGGS, J, JOSEPH BLOGGS, or Joseph of the family Bloggs? Is the man or woman an elector, or is your person (the legal entity created by Birth Registration) the elector?
Duty https://thelawdictionary.org/duty/
In its use in Jurisprudence, this word is the correlative of right. Thus,wherever there exists a right in any person, there also rests a corresponding duty upon some other person or upon all persons generally. But it is also used, in a wider sense, to designate that class of moral obligations which lie outside the jural sphere; such, namely, as rest upon an imperative ethical basis, but have not been recognized by the law as within its proper province for purposes of enforcement or redress. Thus, gratitude towards a benefactor is a duty, but its refusal will not ground an action. In this meaning “duty” is the equivalent of “moral obligation,” as distinguished from a “legal obligation.”
person
From Bouvier’s Law Dictionary
This word is applied to men, women and children, who are called natural persons. In law, man and person are not exactly synonymous terms.
Any human being is a man, whether he be a member of society or not, whatever may be the rank he holds, or whatever may be his age, sex, &c. A person is a man considered according to the rank he holds in society, with all the rights to which the place he holds entitles him, and the duties which it imposes. 1 Bouv. Inst. n. 137.
2. It is also used to denote a corporation which is an artificial person. 1 Bl. Com. 123; 4 Bing. 669; C. 33 Eng. C. L R. 488; Woodes. Lect. 116; Bac. Us. 57; 1 Mod. 164.
3. But when the word “Persons” is spoken of in legislative acts, natural persons will be intended, unless something appear in the context to show that it applies to artificial persons.
legal person
: a body of persons or an entity (as a corporation) considered as having many of the rights and responsibilities of a natural person and especially the capacity to sue and be sued

Corporation sole
A corporation sole is a legal entity consisting of a single (“sole”) incorporated office, occupied by a single (“sole”) natural person.[1][2] This structure allows corporations (often religious corporations or Commonwealth governments) to pass without interruption from one officeholder to the next, giving positions legal continuity with subsequent officeholders having identical powers and possessions to their predecessors. A corporation sole is one of two types of corporation, the other being a corporation aggregate.[3]
