48. 政府回顾了法律和政策框架，并提及《移民法》第 501 条。它还回顾说，其通用签证制度要求所有非公民持有有效签证才能进入或留在澳大利亚。澳大利亚强制性拘留框架规定，非法非公民必须被拘留，直到他们被驱逐出澳大利亚(只要合理可行)或获得签证。已经用尽留在澳大利亚的所有途径的人必须离开。不自愿离开的非法非公民可能被拘留，并可能被非自愿地驱逐出澳大利亚，在这种情况下，驱逐不会违反该国的不驱回义务。
48. The Government recalls the legal and policy framework and refers to section 501 of the Migration Act. It also recalls that its universal visa system requires all non-citizens to hold a valid visa in order to enter or remain in Australia. The Australian mandatory detention framework provides that unlawful non-citizens must be detained until they are removed from Australia (as soon as reasonably practicable) or until they are granted a visa. Individuals who have exhausted all avenues to remain in Australia must depart. Unlawful non-citizens who do not depart voluntarily may be detained and may be involuntarily removed from Australia, in which case removal would not breach the country’s non-refoulement obligations.
