Problem: Given the question: Extract the answer to the question from the following context. Question: What is one of the two types of visas required to return to Australia from Norfolk Island per the Migration Act? Context: Non-Australian citizens who are Australian permanent residents should be aware that during their stay on Norfolk Island they are "outside of Australia" for the purposes of the Migration Act. This means that not only will they need a still-valid migrant visa or Resident return visa to return from Norfolk Island to the mainland, but also the time spent in Norfolk Island will not be counted for satisfying the residence requirement for obtaining a Resident return visa in the future. On the other hand, as far as Australian nationality law is concerned, Norfolk Island is a part of Australia, and any time spent by an Australian permanent resident on Norfolk Island will count as time spent in Australia for the purpose of applying for Australian citizenship.
