Do Australia passport holders need a visa to visit PR?

Puerto Rico is a U.S. territory, so U.S. entry rules apply. Australian passport holders do not need a visa for tourism but must obtain an approved ESTA (Electronic System for Travel Authorization) before travel under the U.S. Visa Waiver Program, for stays up to 90 days. Puerto Rico is an unincorporated territory of the United States, and there is no separate immigration system: visitors clear U.S. federal immigration controls and the U.S. Visa Waiver Program (VWP) applies. Australia is one of the designated VWP countries, so an Australian ordinary passport holder traveling for tourism or a short visit does not need a B-2 visitor visa. Instead, the traveler must hold a valid biometric e-passport and obtain an approved ESTA online before boarding. An approved ESTA permits stays of up to 90 days per entry and is generally valid for two years (or until the passport expires, whichever is sooner) for multiple trips. As of 2026 the ESTA fee is USD 40.27 (a 4.00 processing fee charged on every application plus a 36.27 authorization fee charged only if approved); the fee rose sharply from USD 21 in late 2025. Apply via the official CBP site at esta.cbp.dhs.gov at least 72 hours before departure. Note that final admission is always at the discretion of the U.S. Customs and Border Protection officer at the port of entry, and the VWP prohibits paid or unpaid employment. Because flights to Puerto Rico typically route through the U.S. mainland, the ESTA is required regardless.
