Right of residence in Australia
13 Ms Walsh contended that she did not become a citizen of PNG on Independence Day, and so did not cease to be an Australian citizen, because:
· she was entitled to permanent residence in Australia by virtue of her status as an Australian citizen; and/or
· she was entitled in any event to residence in Australia by virtue of her father's entitlement to permanent residence.
14 The primary judge rejected each of those contentions. His Honour's conclusions in this respect are the subject of the document styled "Notice of cross appeal and of contention to affirm judgment on grounds other than those relied on by Court below" filed on behalf of Ms Walsh. This document should be regarded as a cross appeal, as it does not seek to uphold the orders actually made by the primary judge (which are referred to later in these reasons) on a different ground. Rather, what is sought is a declaration, which the primary judge declined to make, that Ms Walsh remained an Australian citizen notwithstanding the independence of PNG, and the provisions of Regulation 4 of the Independence Regulations.
15 Section 65(4) of the PNG Constitution can only sensibly be read as referring to "Australia" in a sense that does not include the (former) territories of Papua and New Guinea. Thus Ms Walsh became a PNG citizen on Independence Day, unless she then had a right to permanent residence in (mainland) Australia.
16 In 1975 the Migration Act 1958 (Cth) ("the Migration Act") imposed immigration controls upon an "immigrant" proposing to enter Australia. The Migration Act was then framed as a law with respect to immigration, deportation and emigration (under s 51(xxvii) of the Constitution). Section 6(1) of that Act provided that an "immigrant" who entered Australia without an "entry permit" thereby became a "prohibited immigrant", and thus liable to deportation under s 18. An "immigrant" could obtain an "entry permit" under s 6(2) which could be either temporary or permanent in character. A person who was not an "immigrant" was not subject to that control, and therefore by implication had the right to enter and remain permanently in Australia.
17 A fundamental change in the nature of the migration legislation was effected by the Migration Amendment Act 1983 (Cth), which came into effect in 1984. The amending legislation was enacted pursuant to the power to make laws in respect of aliens (under s 51(xix) of the Constitution). Thereafter the Migration Act regulated entry by "non-citizens" into Australia rather than immigrants. Since 1984 Australian citizens have had the right to enter and reside in Australia: Air Caledonie International v Commonwealth (1988) 165 CLR 462 at 469. But in 1975 at Independence Day, in determining whether Ms Walsh had a right to permanent residence in Australia, the question was not whether Ms Walsh was an Australian citizen, but whether, had she sought to enter Australia, she would have been an "immigrant".
18 "Immigrant" was defined in s 5(1) of the Migration Act so as to include:
"… a person intending to enter, or who has entered, Australia for a temporary stay only, where he would be an immigrant if he intended to enter, or had entered, Australia for the purpose of staying permanently."
19 A member of the Australian community returning home to Australia after a temporary absence abroad is not an "immigrant" in respect of whose entry the Parliament might legislate under s 51(xxvii) of the Constitution: Potter v Minahan (1908) 7 CLR 277; Donohoe v Wong Sau (1925) 36 CLR 404; Re Patterson; Ex parte Taylor (2001) 182 ALR 657 at [245] - [247], [367] - [368]. The definition in s 5(1) thus assumes an underlying concept of an "immigrant" as a person whose home is outside Australia, and who enters or is seeking to enter Australia. The Commonwealth's power to control immigration is, under s 51(xxvii) of the Constitution and the Migration Act, largely confined to persons who are not members of the Australian community: Pryles (supra) at p 42. Possession of Australian citizenship may be an important factor in determining whether a person has become absorbed in the Australian community, and thus outside the immigration power, but it may not be decisive. An Australian national may, in some circumstances, enter Australia as an immigrant and regulation of such entry is within the constitutional competence of the Commonwealth Parliament: The King v Macfarlane; Ex Parte O'Flanagan and O'Kelly (1923) 32 CLR 518 at 580.
20 In 1975, the Migration Act did not contain a definition of "Australia". Prima facie, therefore, that expression had the meaning given in s 17(a) of the Acts Interpretation Act 1901 (Cth), which at the time expressly excluded external Territories. No submission was put on behalf of Ms Walsh that the Migration Act evinced a contrary intention. Thus "Australia", for migration purposes, was limited at the relevant time to the area comprising the States and the internal Territories.
21 As at Independence Day, Ms Walsh had been born in and lived all her life at a place which was outside "Australia" for the purposes of the Migration Act. She came to Australia for the first time in 1985 for a holiday. Had she sought to enter "Australia" in 1975, she would have been an "immigrant", and she could not have done so without obtaining the discretionary grant of a permit under the Migration Act. At that time, therefore, Ms Walsh did not have a right to permanent residence in Australia by virtue of her Australian citizenship.
22 Reliance was placed, by the solicitor for Ms Walsh, on the "Australian Citizenship Instructions", which gave an overview of government policy at the time on whether Australian citizenship automatically results in a right of permanent residence in mainland Australia in the case of people born in Papua New Guinea. Paragraph 1.3.6 of those instructions was in the following terms:
"In relation to Papua prior to independence:
· Papua was a Territory of Australia and was defined as part of Australia under the Australian Citizenship Act 1948, but not under the Migration Act 1958.
