Background
7 The Migration Act establishes a visa system to regulate the entry into, and residence (permanent or temporary) in, Australia of those persons coming to or remaining in Australia who are not Australian citizens. Section 4 of the Migration Act states:
4 Object of Act
(1) The object of this Act is to regulate, in the national interest, the coming into, and presence in, Australia of non-citizens.
(2) To advance its object, this Act provides for visas permitting non-citizens to enter or remain in Australia and the Parliament intends that this Act be the only source of the right of non-citizens to so enter or remain.
(3) To advance its object, this Act requires persons, whether citizens or non-citizens, entering Australia to identify themselves so that the Commonwealth government can know who are the non-citizens so entering.
(4) To advance its object, this Act provides for the removal or deportation from Australia of non-citizens whose presence in Australia is not permitted by this Act.
(5) To advance its object, this Act provides for the taking of unauthorised maritime arrivals from Australia to a regional processing country.
8 Section 29(1) provides:
29 Visas
(1) Subject to this Act, the Minister may grant a non-citizen permission, to be known as a visa, to do either or both of the following:
(a) travel to and enter Australia;
(b) remain in Australia.
…
9 Sections 13 and 14 of the Migration Act establish a distinction between lawful and unlawful non-citizens. Sections 13(1) and 14(1) provide:
13 Lawful non-citizens
(1) A non-citizen in the migration zone who holds a visa that is in effect is a lawful non-citizen.
…
14 Unlawful non-citizens
(1) A non-citizen in the migration zone who is not a lawful non-citizen is an unlawful non-citizen.
…
10 The concept of the "migration zone" is foundational to the reach of the Migration Act, and the visa system it implements. The term "migration zone", and a number of other terms upon which it depends and to which it refers, are given defined meanings by the Migration Act. The end result is a complicated one, as will be seen. Nevertheless, the ultimate question to which all the resulting complexity is directed (at least so far as the present case is concerned) is who must have a visa in order to work in the offshore areas and activities to which I will direct attention. The Amending Act introduced new requirements, and extended old ones. The Determination effectively cancelled those alterations.
11 Three important matters of construction must be borne in mind in the journey through the thicket of intertwined definitions and when attention is given to the changes which were made by the Amending Act and then undone by the Determination.
12 The first matter is the reminder by McHugh J in Kelly v R (2004) 218 CLR 216 at [103]:
103 … the function of a definition is not to enact substantive law. It is to provide aid in construing the statute. Nothing is more likely to defeat the intention of the legislature than to give a definition a narrow, literal meaning and then use that meaning to negate the evident policy or purpose of a substantive enactment. There is, of course, always a question whether the definition is expressly or impliedly excluded. But once it is clear that the definition applies, the better - I think the only proper - course is to read the words of the definition into the substantive enactment and then construe the substantive enactment - in its extended or confined sense - in its context and bearing in mind its purpose and the mischief that it was designed to overcome. To construe the definition before its text has been inserted into the fabric of the substantive enactment invites error as to the meaning of the substantive enactment.
13 The second matter is that s 11B(1) of the Acts Interpretation Act 1901 (Cth) directs:
11B Amending Act to be construed with amended Act
(1) Every Act amending another Act must be construed with the other Act as part of the other Act.
…
14 The third matter is that delegated legislation (such as the Determination) must conform to the purposes for which it is enabled (see e.g. Swan Hill Corporation v Bradbury (1937) 56 CLR 746 at 756, 757-8; R v Toohey; Ex parte Northern Land Council (1981) 151 CLR 170 at 186).
15 In the Migration Act, the following definitions in s 5(1) bear directly upon the terms of the Migration Act, before the Amending Act took effect:
5 Interpretation
(1) In this Act, unless the contrary intention appears:
…
Australian resources installation means a resources installation that is deemed to be part of Australia because of the operation of section 8.
…
enter Australia, in relation to a person, means enter the migration zone.
…
migration zone means the area consisting of the States, the Territories, Australian resource installations and Australian sea installations and, to avoid doubt, includes:
(a) land that is part of a State or Territory at mean low water; and
(b) sea within the limits of both a State or a Territory and a port; and
(c) piers, or similar structures, any part of which is connected to such land or to ground under such sea;
but does not include sea within the limits of a State or Territory but not in a port.
…
remain in Australia, in relation to a person, means remain in the migration zone.
…
resources installation means:
(a) a resources industry fixed structure within the meaning of subsection (10); or
(b) a resources industry mobile unit within the meaning of subsection (11).
…
16 Section 5(10)-(14) stated:
5 Interpretation
…
(10) A reference in this Act to a resources industry fixed structure shall be read as a reference to a structure (including a pipeline) that:
(a) is not able to move or be moved as an entity from one place to another; and
(b) is used or is to be used off-shore in, or in any operations or activities associated with, or incidental to, exploring or exploiting natural resources.
(11) A reference in this Act to a resources industry mobile unit shall be read as a reference to:
(a) a vessel that is used or is to be used wholly or principally in:
(i) exploring or exploiting natural resources by drilling the seabed or its subsoil with equipment on or forming part of the vessel or by obtaining substantial quantities of material from the seabed or its subsoil with equipment of that kind; or
(ii) operations or activities associated with, or incidental to, activities of the kind referred to in subparagraph (i); or
(b) a structure (not being a vessel) that:
(i) is able to float or be floated;
(ii) is able to move or be moved as an entity from one place to another; and
(iii) is used or is to be used off-shore wholly or principally in:
(A) exploring or exploiting natural resources by drilling the seabed or its subsoil with equipment on or forming part of the structure or by obtaining substantial quantities of material from the seabed or its subsoil with equipment of that kind; or
(B) operations or activities associated with, or incidental to, activities of the kind referred to in sub-subparagraph (A).
(12) A vessel of a kind referred to in paragraph (11)(a) or a structure of a kind referred to in paragraph (11)(b) shall not be taken not to be a resources industry mobile unit by reason only that the vessel or structure is also used or to be used in, or in any operations or activities associated with, or incidental to, exploring or exploiting resources other than natural resources.
(13) The reference in subparagraph (11)(a)(ii) to a vessel that is used or is to be used wholly or principally in operations or activities associated with, or incidental to, activities of the kind referred to in subparagraph (11)(a)(i) shall be read as not including a reference to a vessel that is used or is to be used wholly or principally in:
(a) transporting persons or goods to or from a resources installation; or
(b) manoeuvring a resources installation, or in operations relating to the attachment of a resources installation to the Australian seabed.
(14) A resources installation shall be taken to be attached to the Australian seabed if:
(a) the installation:
(i) is in physical contact with, or is brought into physical contact with, a part of the Australian seabed; and
(ii) is used or is to be used, at that part of the Australian seabed, wholly or principally in or in any operations or activities associated with, or incidental to, exploring or exploiting natural resources; or
(b) the installation:
(i) is in physical contact with, or is brought into physical contact with, another resources installation that is taken to be attached to the Australian seabed by virtue of the operation of paragraph (a); and
(ii) is used or is to be used, at the place where it is brought into physical contact with the other installation, wholly or principally in or in any operations or activities associated with, or incidental to, exploring or exploiting natural resources.
17 Section 8 provided:
8 Certain resources installations to be part of Australia
(1) For the purposes of this Act, a resources installation that:
(a) becomes attached to the Australian seabed after the commencement of this subsection; or
(b) at the commencement of this subsection, is attached to the Australian seabed;
shall, subject to subsection (2), be deemed to be part of Australia and shall be deemed not to be a place outside Australia.
(2) A resources installation that is deemed to be part of Australia by virtue of the operation of this section shall, for the purposes of this Act, cease to be part of Australia if:
(a) the installation is detached from the Australian seabed, or from another resources installation that is attached to the Australian seabed, for the purpose of being taken to a place outside the outer limits of Australian waters (whether or not the installation is to be taken to a place in Australia before being taken outside those outer limits); or
(b) after having been detached from the Australian seabed otherwise than for the purpose referred to in paragraph (a), the installation is moved for the purpose of being taken to a place outside the outer limits of Australian waters (whether or not the installation is to be taken to a place in Australia before being taken outside those outer limits).
18 Before the Amending Act, therefore, a visa was required to work upon (and remain on) structures or vessels referred to in s 8 of the Migration Act, subject to the limitations in the various definitions incorporated in that section, which was itself a definitional section directed ultimately to the question of when a person was in the migration zone and, accordingly, required a visa to enter and remain in Australia and would be an unlawful non-citizen without a visa.
19 The operation of this part of the Migration Act was considered by McKerracher J in Allseas Construction SA v Minister for Immigration and Citizenship (2012) 203 FCR 200. His Honour ruled that two pipelaying vessels, which were laying pipelines between the Gorgon and Jansz gas fields and Barrow Island off Western Australia, did not come (with the workers on those vessels) into the migration zone. The workers were mostly non-citizens. Attention was focussed on s 8 of the Migration Act and, in turn, on s 5(10)-(14) of the Migration Act. McKerracher J ruled that the vessels came within the terms of s 5(13)(b) of the Migration Act, that they were therefore not a "resources industry mobile unit" and so not a "resources installation" or "Australian resources installation", were not deemed to be part of Australia and were not within the migration zone. The workers on the vessels therefore did not need visas.
20 The applicants in the present proceedings, amongst others, were dissatisfied with that outcome. The Government established a Migration Maritime Taskforce ("the Taskforce"). The Taskforce recommended legislative change.
21 Material before the Court on the present application offered the following summary:
The Taskforce recommended that the existing legislative framework that essentially provides that persons are in the migration zone based on where they are physically located be supplemented with a new legislative concept. This new concept would provide that all offshore resource workers, including support staff, are taken to be in the migration zone when they are engaged to conduct or support activities regulated by Commonwealth, State and Territory legislation relating to the exploration and exploitation of Australia's natural resources.
22 The Government did not act on a recommendation in terms this broad, but it did introduce the Bill for the Amending Act, which sought to introduce two important changes: first, to extend the migration zone to include the concept of "offshore resources activity"; and, secondly, to insert new requirements that persons involved in such activity (whether or not within the existing operation of s 8) were not allowed to work without a permanent visa or a visa prescribed for that purpose.
23 Importantly, however, and in contradistinction to the operation of s 8 (and s 9 which dealt with "sea installations" in a similar way to s 8) the new provisions were to be accompanied by a Ministerial power to make exceptions, or to include new matters. The scheme of the new provisions (which I will set out shortly) was intended to take existing Commonwealth legislative regulation as a reference point.
24 The Explanatory Memorandum explained this, and other, features of the Bill in the following way:
OUTLINE
…
The amendments in this Bill will regulate foreign workers participating in offshore resources activities by bringing these persons into the migration zone and thereby requiring them to hold a visa under the Act. In terms of selecting offshore resources activities, the Taskforce recommended referencing a legislative solution that comprehensively administer the activities of the offshore resources industry comprising the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (the Offshore Petroleum Act) and the Offshore Minerals Act 1994 (the Offshore Minerals Act). In addition to these two Acts, the Bill will create a power for the Minister to make a determination in writing for the purposes of defining offshore resources activity. This will provide the Minister with flexibility to declare certain activities administered by other regulatory schemes as offshore resource activities for the purposes of the new deemed migration zone. This would include projects that take place in areas that are within the coastal waters of the States and the Northern Territory which are regulated under State and Territory laws rather than their Commonwealth equivalents.
The legislative measures will supplement the current framework under the Act which defines, as part of the migration zone, Australian resources installations and Australian sea installations. Together with the existing provisions in the Act, this new comprehensive framework will ensure that workers in Australia's offshore resources industry are regulated under the Act and required to hold specific visas. Individuals who engage in offshore resources activities in Australia's offshore maritime zones will be subject to existing compliance measures in the Act which address breaches of work and visa conditions.

SCHEDULE 1 - Amendments
Part 1 - Amendments
Migration Act 1958
…
Item 6 After section 9
…
38. New section 9A creates a new framework that provides that persons in an area participating in, or supporting, an offshore resources activity are taken to be in the migration zone (the deeming provision). New section 9A further clarifies how this new framework operates by deeming when persons are taken to be in Australia, taken to travel to Australia, taken to enter Australia and or taken to leave Australia. It further defines offshore resources activity for the purposes of the Act. The purpose of this amendment is to bring persons participating in, or supporting, an offshore resources activity in the relevant area within the ambit of the Act, thereby requiring these persons to hold visas.
…
41. New section 9A is based on the recommendations of the Taskforce. The Taskforce recommended that the existing legislative framework that essentially provides that persons are in the migration zone based on where they are physically located be supplemented with a new legislative concept. The policy intention is to provide that all offshore resource workers, including support staff, are taken to be in the migration zone when they are engaged to conduct activities regulated by Commonwealth, State and Territory legislation relating to the exploration and exploitation of Australia's natural resources.
…
Meaning of offshore resources activity
Subsection 9A(5)
…
92. New paragraphs 9A(5)(a) and 9A(5)(b) make it clear that all regulated operations under the Offshore Petroleum Act and all activities performed under a licence or a special purpose consent under the Offshore Minerals Act are captured by the definition of offshore resources activity unless the Minister has excluded the operation or activity by using his powers under subsection 9A(6). This would allow the Minister to exclude from the Act activities defined under the Offshore Petroleum Act and the Offshore Minerals Act which the Minister considers unsuitable to be captured by the definition of offshore resources activity.
…
94. New subparagraph 9A(5)(c)(ii) provides that an offshore resources activity can also include an activity, operation or undertaking (however described) that is being carried out, or is to be carried out under a law of the Commonwealth, a State or a Territory determined by the Minister under subsection 9A(6).
95. The purpose of this amendment is to enable the Minister to determine as an offshore resources activity, an activity which is not covered by the Offshore Petroleum Act or the Offshore Minerals Act under new subsection 9A(6) for the purposes the deeming provision in new subsection 9A(1). Therefore, a person who is carrying out an activity under legislation that the Minister has determined to be an offshore resources activity would be taken to be in the migration zone because they are participating in an offshore resources activity.
…
Subsection 9A(6)
99. New subsection 9A(6) provides that the Minister may, in writing, make a determination for the purposes of the definition of offshore resources activity in subsection 9A(5).
100. More specifically, this amendment provides the Minister with the power to make determinations with respect to the definition of offshore resources activity by:
• exempting certain regulated operations under the Offshore Petroleum Act from the definition of offshore resources activity;
• exempting certain activities performed under a licence or a special purpose consent under the Offshore Minerals Act from the definition of offshore resources activity;
• capturing certain activities, operations or undertakings carried out, or to be carried, out under a law of the Commonwealth, a State or a Territory;
• determining the specific law of the Commonwealth, State or a Territory in which those activities are carried out under; and/or
• limiting the area in which those activities are carried out under.
101. The purpose of this amendment is to provide the Minister with the flexibility and ability to exempt certain activities administered by the Offshore Petroleum Act and the Offshore Minerals Act from the definition of offshore resources activity. Further, this amendment will provide the Minister with the ability to capture certain other activities not administered by these two Acts but administered by a law of the Commonwealth, a State or a Territory.
…
Item 8 After subsection 41(2A)
…
Subsections 41(2B) and 41(2C)
123. New subsection 41(2B) provides that in addition to any restrictions applying because of Regulations made for the purposes of paragraph 41(2)(b), a condition of a visa that allows the holder of the visa to work is not taken to allow the holder to participate in, or support, an offshore resources activity in relation to any area unless the visa is:
• a permanent visa;
• or a visa prescribed by the regulations for the purposes of this subsection.
124. The purpose of this amendment is to ensure that all non-citizens engaged in an offshore resources activity hold a visa or a permanent visa to participate in, or support, the relevant activity.
125. A person who is not the holder of a permanent visa or a visa prescribed by the Regulations for the purposes of new subsection 41(2B) could not lawfully participate in, or support, an offshore resources activity.
…
128. New subsection 41(2C) provides that to avoid doubt, for the purposes of subsection 41(2B), a person may participate in, or support, an offshore resources activity in relation to an area whether the person:
• is on an Australian resources installation in the area;
• or is, under section 9A, otherwise in the area to participate in, or support, the activity.
129. This new subsection mirrors new subsection 9A(8) which is inserted by item 6 above. The purpose of this amendment is to put beyond doubt that persons engaged in any type of offshore resources activity in the relevant area will be required to hold a permanent visa; or a visa prescribed by the Regulations to participate or support that activity. This will be the case regardless of whether the person is engaged in an activity on an Australian resources installation and is already taken to be in the migration zone under the Act or is participating in or supporting an offshore resources activity for the purposes of new section 9A and will therefore be taken to be in the migration zone under new subsection 9A(1).
…
(Emphasis in original.)
25 The applicants rely heavily on the legislative purpose which is indicated in the Explanatory Memorandum, although they do so as confirmation of the intention to be discerned from the statutory text itself, and not to displace that statutory text.
26 It will not be necessary to set out the new provisions in ss 41(2B) and (2C), the terms and effect of which are adequately indicated by the extracts from the Explanatory Memorandum set out above. However, the relevant parts of the new s 9A must be set out, together with the amended definitions which assist in its own operation as a definitional provision.
27 A note was added to the end of each of the definitions of "enter Australia" and "migration zone" in s 5 as follows:
Note: See also section 9A, which concerns offshore resources activities.
28 A new definition of "offshore resources activity" was added to s 5:
offshore resources activity has the meaning given by subsection 9A(5).
29 The new s 9A(1), (5), (6), (7) and (8) stated:
9A Migration zone etc. - offshore resources activities
Migration zone etc.
(1) For the purposes of this Act, a person is taken to be in the migration zone while he or she is in an area to participate in, or to support, an offshore resources activity in relation to that area.
Example 1: A person is taken to be in the migration zone under this section if the person is on a vessel in an area to participate in an offshore resources activity under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 in that area by exploring for, or recovering, petroleum.
Example 2: A person who is a member of the crew of the vessel is also taken to be in the migration zone under this section if the person is supporting the offshore resources activity.
Example 3: Neither a stowaway on the vessel, nor a person on the vessel because the person was rescued at sea, is taken to be in the migration zone, because neither is participating in, or supporting, the offshore resources activity.
…
Meaning of offshore resources activity
(5) In this section:
offshore resources activity, in relation to an area, means:
(a) a regulated operation (within the meaning of section 7 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006) that is being carried out, or is to be carried out, within the area, except an operation determined by the Minister under subsection (6); or
(b) an activity performed under a licence or a special purpose consent (both within the meaning of section 4 of the Offshore Minerals Act 1994) that is being carried out, or is to be carried out, within the area, except an activity determined by the Minister under subsection (6); or
(c) an activity, operation or undertaking (however described) that is being carried out, or is to be carried out:
(i) under a law of the Commonwealth, a State or a Territory determined by the Minister under subsection (6); and
(ii) within the area, as determined by the Minister under subsection (6).
(6) The Minister may, in writing, make a determination for the purposes of the definition of offshore resources activity in subsection (5).
(7) A determination made under subsection (6) is a legislative instrument, but section 42 (disallowance) of the Legislative Instruments Act 2003 does not apply to the determination.
(8) To avoid doubt, for the purposes of subsection (1), a person may participate in, or support, an offshore resources activity in relation to an area whether the person:
(a) is on an Australian resources installation in the area; or
(b) is otherwise in the area to participate in, or support, the activity.
(Emphasis in original.)
30 The reference in s 9A(5)(a) and (b) to definitional provisions in the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (Cth) and the Offshore Minerals Act 1994 (Cth) respectively is apt to initiate further excursions into the legislative interstices of those two Acts. They deal with exploration, production and mining activities in offshore areas under the control of Australia for which particular leases, permits or consents are necessary. It is apparent that, subject to the power of exception in each of s 9A(5)(a) and (b), the intention was to treat those and related activities as ones to which the new requirements for visas, and accompanying restrictions, would apply.
31 It is, in particular, the terms of s 9A(5) and (6) which have been the principal focus of attention in the present proceedings, for reasons which will emerge more clearly shortly.
32 The Amending Act received the Royal Assent on 29 June 2013 and commenced in operation, in accordance with s 2 thereof, 12 months later on 29 June 2014. In the meantime, the political complexion, and policies, of the Government changed after a federal election in September 2013.
33 On 27 March 2014, the new Government introduced a Bill to repeal the whole of the Amending Act. The Bill remains before the Parliament. It is not directly relevant to any legal issue in the present proceedings.
34 On 29 May 2014, one month before the Amending Act was to take effect, the Governor-General, on the advice of the Executive Council, made the Migration Amendment (Offshore Resources Activity) Regulation 2014 (Cth) ("the Regulation"). The intended effect of the Regulation was to prescribe three existing visas for the purpose of the new s 41(2B)(b) of the Migration Act: the Subclass 988 (Maritime Crew) visa; the Subclass 400 (Temporary Work (Short Stay Activity)) visa; and the Subclass 457 (Temporary Work (Skilled)) visa. In addition, changes were made to the expiry arrangements for Maritime Crew visas so that, instead of expiring after five days (with a maximum extension to 30 days) they remained valid for a potentially indefinite period.
35 It may be inferred that the intention behind the prescription of the three classes of temporary visas was to avoid the consequence that, otherwise, those in offshore resource activities would require a permanent visa, a circumstance likely to significantly restrict those non-citizens in the migration zone who would be permitted to carry out such work in addition to Australian citizens.
36 On 16 July 2014 the Senate disallowed the Regulation. By this time the provisions of the Amending Act had commenced. One immediate consequence was that any persons working in an offshore resources activity within the meaning of s 9A required a permanent visa, if not an Australian citizen.
37 On 17 July 2014, the first respondent made the Determination (which was registered on the same day). It provided:
I, MICHAELIA CASH, Assistant Minister for Immigration and Border Protection, acting under subsection 9A(6) of the Migration Act 1958, DETERMINE:
1. for the purposes of paragraph 9A(5)(a), a regulated operation (within the meaning of section 7 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006); and
2. for the purposes of paragraph 9A(5)(b), an activity performed under a licence or a special purpose consent (both within the meaning of section 4 of the Offshore Minerals Act 1994).
This instrument, IMMI 14/077, commences on the day it is registered on the Federal Register of Legislative Instruments.
38 The effect of the Determination was to except the whole of the defined content of "offshore resources activity" stated by s 9A(5)(a) and (b).
