Which act governs entry into and presence in Australia and deportation of aliens?

• A. Migration Act 1958 (Cth)
• B. Australian Citizenship Act 2007
• C. Customs Act 1901
• D. Racial Discrimination Act 1975

Answer: (A)

The main concept is the legal framework that controls who can enter and stay in Australia, and how someone without lawful status can be removed. The Migration Act 1958 (Cth) is the central law for this area. It lays out who may enter, how visas are granted or refused, and the rules for staying in Australia, along with the powers to detain and deport unlawful non-citizens. This act also governs visa cancellations and removal orders, making immigration enforcement a core part of its scope. The other acts don’t cover entry, presence, or deportation: the Australian Citizenship Act 2007 handles citizenship matters; the Customs Act 1901 focuses on goods and border controls related to trade rather than individuals’ immigration status; and the Racial Discrimination Act 1975 addresses discrimination but does not govern immigration decisions or removal processes.
