Fiji gives visa on arrival to a large number of countries. My wife and I recently visited Fiji using our Indian Passports, and had no trouble entering or exiting without a visa. We had to fill an immigration form and a health-declaration (ebola related). The immigration officers didn’t ask for anything else. They just stamped our passport with a 4 month stay permit and let us in. Didn’t cost any money either.
FYI – we used fresh passports – with no previous visas or even entry stamps from any other country.
