These provisions show that Parliament has used the expression "Aboriginal race of Australia" to refer to the group of persons in the modern Australian population who are descended from the inhabitants of Australia immediately prior to European settlement. It follows that an "Aboriginal person" is, for the purposes of this Act, one of those descendants.
In so using the expression "Aboriginal race of Australia" Parliament has in my opinion here done nothing more than give this expression the same meaning it has in ordinary speech. Dictionary definitions of "race" all refer to the notion of common descent: both the Macquarie Dictionary, 2nd Ed. and the Oxford English Dictionary, 2nd Ed., give as the primary meaning of the word "race" the following: "a group of
persons connected by common descent ...". While the Macquarie Dictionary gives as the meaning of "aborigine": "one of a race of tribal peoples, the earliest inhabitants of Australia", the Oxford English Dictionary gives as a meaning of the word "aboriginal": "An original inhabitant of any land, now usually as distinguished from subsequent European colonists. Also spec. one of the aboriginal inhabitants of Australia." It is this meaning that the Australian National Dictionary takes as the primary meaning of the word in Australian English usage. That Parliament intended the expression "Aboriginal persons" as defined in the Act to bear the meaning it has in ordinary speech is I think clearly shown by the second paragraph of the preamble which records Parliament's recognition of the expression "Aboriginal persons" as one in current community usage to identify descendants of the inhabitants of Australia before European settlement.
Since the Act itself makes it clear that proof of descent from the pre-European settlement inhabitants of Australia is essential before a person can come within the expression "Aboriginal person" in the Act, I reject the suggestion advanced on behalf of the first respondent that a person without any Aboriginal genes but who has identified with an Aboriginal community and who is recognised by that community as one of them can be an "Aboriginal person" for the purposes of this particular Act. It follows that adoption by Aboriginals of a person without any aboriginal descent and the raising of that person as an Aboriginal (a possibility mentioned by the first respondent) will not, because of the statutory requirement for descent, bring that person within the description "Aboriginal person".
The next question is whether the expression "Aboriginal person" denotes only full blood descendants of the pre-European settlement inhabitants of the continent or whether it comprehends persons of mixed descent, i.e., persons who possess some Aboriginal genes. The preamble and s. 3 of the Act, in referring to the people whose descendants are now known as Aboriginal persons and also to Aboriginal peoples, suggest that this comprises a large group. The same suggestion is implicit in various provisions of the Act, including s. 7 (which prescribes the functions of the Aboriginal and Torres Strait Islander Commission) and s. 94 (which prescribes the functions of each Regional Council). Section 91 divides the whole of Australia, for the purposes of the Act, into 36 regions, five of which comprise the State capitals Sydney, Brisbane, Adelaide, Hobart and Perth (although the precise boundaries of these and the other 31 regions are as determined from time to time by the Minister). I can take judicial notice of the fact that there are few, if any, full blood descendants of the pre-settlement inhabitants of the continent living in any of these five regions: twenty years ago judicial notice was taken that "for a long time it has been widely known that there remain very few [Aboriginal] persons of the full blood" in the whole continent: Re Bryning [1976] V.R. 100 at 103. Parliament can be taken to have been well aware of this fact when it enacted this legislation which establishes an elaborate system designed to vest in Aboriginals and Torres Strait Islanders political, administrative and financial powers to be used for the benefit of all persons of those races. Such a legislative scheme is unlikely to have been intended to benefit only a tiny group within the Australian community. A reading of the Act against this factual background requires acceptance of the proposition that the expression "Aboriginal person" comprehends not only full blood descendants of the original inhabitants, but also persons who possess some Aboriginal genetic material. Persons with a limited Aboriginal genetic heritage are therefore not necessarily excluded from being "Aboriginal persons" within the meaning of that term in the Act. Such a reading conforms to Australian vernacular usage, something recognised in Re Bryning, supra, where Lush J said at 103:
"In this country, in everyday usage, the meaning of the words "aborigine" and "aboriginal" varies. In contrast, for instance, with the word "half-caste" as in the old statutes, they undoubtedly mean a man of the full blood, but when used to describe a general body of persons, without adjectives and without contrasting words or phrases, I do not think that they have had this meaning for many years.
It must, I think, be remembered that this is a word that is probably much more widely used in this country than in other English-speaking countries. In this country it has certainly been used to describe persons in groups or societies irrespective of the question of mixture of blood."
