Context: The island is subject to separate immigration controls from the remainder of Australia. Until recently immigration to Norfolk Island even by other Australian citizens was heavily restricted. In 2012, immigration controls were relaxed with the introduction of an Unrestricted Entry Permit for all Australian and New Zealand citizens upon arrival and the option to apply for residency; the only criteria are to pass a police check and be able to pay into the local health scheme. From 1 July 2016, the Australian migration system will replace the immigration arrangements currently maintained by the Norfolk Island Government.
