Do Australia passport holders need a visa to visit HT?

No visa required. Australian ordinary passport holders can enter Haiti visa-free for tourism, paying only a US$10 tourist fee on arrival. Australian ordinary passport holders do not need a visa to visit Haiti for tourism. The Embassy of Haiti confirms that, as a general rule, tourists are visa-exempt; only nationals of nine specified countries (Dominican Republic, Panama, Colombia, Cuba, Syria, Libya, Iran, Vietnam and Yemen) require a visa in advance. Australia is not on that list. On arrival at the airport, visa-exempt visitors pay a US$10 tourist fee and are admitted for a short tourist stay (commonly up to 90 days). Passports must be valid for at least six months from the date of entry. Travelers should also be ready to show proof of onward/return travel and may be asked to show sufficient funds. A yellow fever vaccination certificate can be required if arriving from or transiting a country with risk of yellow fever transmission. Note that the Australian Government (Smartraveller) maintains its highest "Do not travel" advisory for Haiti due to ongoing armed violence and kidnapping; Australia has no embassy there. These are safety, not visa, considerations, but they are critical for any traveler. Entry rules can change at short notice, so confirm with the nearest Haitian embassy or consulate before departure.
