Do Australia passport holders need a visa to visit GM?

Australian passport holders do not need a visa for short tourist visits to The Gambia. As Australia is a Commonwealth member, citizens are visa-exempt for up to 90 days. In practice, immigration usually stamps an initial 28-day stay on arrival, which can be extended at the Immigration Office in Banjul up to the 90-day limit. The Gambia grants visa-free entry to citizens of Commonwealth of Nations member states, the EU, ECOWAS, and countries with reciprocal visa-waiver agreements for stays of up to 90 days for tourism or business. Australia is a Commonwealth member, so Australian ordinary passport holders need no visa for a short tourist stay. The official Government of The Gambia immigration guidance confirms the 90-day visa-free allowance for Commonwealth citizens. In practice, immigration officers commonly grant an initial 28-day entry stamp on arrival; this can be extended in two further 28-day increments at the Immigration Office in Banjul or designated tourist police stations, up to the overall limit. There is no visa fee, but a compulsory Airport Security Fee of US$20 (or equivalent in euros, pounds sterling, or Gambian dalasi) is payable on both arrival and departure at the airport. A yellow fever vaccination certificate is required if arriving from a country with risk of yellow fever transmission, and is strongly recommended given regional risk. Passports should be valid for at least six months. Travelers should carry proof of onward/return travel and sufficient funds. Sources consulted include the official Government of The Gambia website, the Gambia Immigration Department, Australia's Smartraveller, and UK GOV travel advice. Verdict: visa-free for short tourist stays.
