Chile has a Mediterranean climate and four seasons, with the best time to visit being in Spring-Summer, between September and March. Australian citizens must have a visa to enter Chile, and exercise a high degree of caution due to potential demonstrations, civil unrest, and violence. The Protected Borders Plan is no longer in effect, and a current vaccination certificate will not be required when entering Chile. Proof of economic resources through copies of bank accounts or another certificate that proves the possession of, at least, USD $ 46 for every day of residence in Chile is required. Most people travel to Chile by air. Complete a Single Entry Form (FUI) ahead of travel, book a return ticket ahead of entry to Rapa Nui, and reserve a tourist service registered in SERNATUR.
