A valid passport is required for travel to Mexico. For entry to Mexico, your passport must be valid for six months after your final day of travel. For U.S. citizens, obtain or update your passport here: https://travel.state.gov/content/travel/en/passports.html. For Australian citizens, obtain or update your passport here: https://www.passports.gov.au/getting-passport-how-it-works/passport-renewal
No visa is required for U.S. citizens or Australian citizens visiting Mexico for a short stay. Instead, upon arrival, you will complete the Forma Migratoria Multiple (FMM) and receive a Visitor's Permit.
