Do Australia passport holders need a visa to visit HN?

Australian ordinary passport holders do NOT need a visa for tourism in Honduras. You may enter visa-free and stay up to 90 days, which is shared across the CA-4 region (Honduras, Guatemala, El Salvador, Nicaragua). Australia is on Honduras's visa-exempt list, so an ordinary Australian passport holder can travel to Honduras for tourism without obtaining a visa in advance or on arrival. The permitted stay is up to 90 days. Importantly, Honduras is part of the Central America-4 (CA-4) Border Control Agreement together with Guatemala, El Salvador and Nicaragua; the 90-day allowance is shared across all four countries, so time spent in any of them counts toward the same 90-day limit. To re-set the clock you generally must leave the CA-4 zone entirely. No paper tourist card or visa fee applies, but travelers should complete the Honduran immigration/customs pre-check form online before arrival and departure and keep the QR-code confirmation. Carry proof of onward or return travel and ensure your passport is physically stamped on entry to avoid fines on departure. A one-time 30-day extension can be requested in-country at the National Institute of Migration. Passport-validity guidance varies between three and six months across sources; to be safe, hold at least six months' validity beyond your intended departure. There is a departure tax (commonly around US$48 for international flights, usually bundled into airfare) and small land-border fees. These conclusions are corroborated by the Wikipedia visa-policy summary, Australia's Smartraveller listing, and commercial visa references; the verdict is visa-free for short tourist stays.
