To avoid doubt, although subsection 5(1) limits, for the purposes of this Act, the meanings of enter Australia , leave Australia and remain in Australia and as well, because of section 18A of the Acts Interpretation Act 1901 , the meaning of parts of speech and grammatical forms of those phrases, this does not mean:
(a) that, for those purposes, the meaning of in Australia , to Australia or any other phrase is limited; or
(b) that this Act does not extend to parts of Australia outside the migration zone; or
(c) that this Act does not apply to persons in those parts.
Note: See also subsection 9A(3), which deals with when a person is taken to be in Australia, to travel to Australia, to enter Australia or to leave Australia. Section 9A concerns offshore resources activities.
