Plain English

Section 5 contains the definitions that govern the meaning of words and phrases throughout the Migration Act. It defines core concepts such as non-citizen, citizen, visa, officer, lawful non-citizen, unlawful non-citizen, and migration zone.

Where a term is defined in s 5, that definition applies throughout the Act unless the context indicates otherwise. Some terms are defined further in other sections (for example, "member of the family unit" is defined in s 5 but the Regulations also contain detailed definitions).

Practical effect

The definitions in s 5 are the starting point for every question of statutory interpretation under the Migration Act. Courts regularly return to s 5 when construing the Act's provisions. Key definitions that frequently arise in litigation include:

  • Non-citizen — a person who is not an Australian citizen; subject to all migration controls
  • Citizen — an Australian citizen within the meaning of the Australian Citizenship Act 2007; not subject to visa requirements
  • Visa — a visa granted under the Act (see also s 29–30)
  • Migration zone — Australia, but not an excised offshore place
  • Officer — a person who performs functions or exercises powers under the Act, including ABF officers
  • Bridging visa, substantive visa, special purpose visa — each defined and used in multiple other provisions

The Regulations also contain their own Definitions provision (r 1.03) which supplements the Act's definitions for regulatory purposes.
