Most crime takes place in Suva and Nadi away from the resort areas. The best advice is to stick to hotel grounds after dark, and to use extreme caution in Suva, Nadi and other urbanised areas after nightfall. Travelers have been victims of violent crime, particularly in Suva. Travelers have reported the regularity of petty robberies, muggings, and also home-invasions/rape, etc. You will notice the predominance of bars on most peoples' homes. Economic and ethnic strife has led to a low-level hum of violent crime. Some resorts and hotels have more extensive security measures than others which should be taken into account.
Muggings are often carried out by large groups of men so being in a group won't necessarily be a deterrent. Police forces sometimes have difficulties responding to crime, potentially for reasons as mundane as being unable to pay for petrol.
Fijian culture encourages sharing and sometimes small things like shoes will be "borrowed". Often by speaking with the village chief it can be arranged to get things returned.
Also, be aware that homosexual sex may be a crime in Fiji. While Fiji claims to welcome gay travelers, there has been a recent case where a visitor to the country was initially jailed for 2 years for paying a local for homosexual sex. He was later freed on appeal.
Fiji is still run by a military government, following a coup in December 2006. Although its effect has not been prominent in the resort areas of Nadi, it has led to economic decline, and a decrease in the rule of law. Journalists may be blacklisted for political reasons. Those whose employment involves reporting controversial political activities should take extra care to ensure that their visas are in order before visiting Fiji.
Fiji is relatively free of disease compared to most of the tropics. Avoid mosquito-borne illnesses, such as dengue fever and even elephantiasis by covering up thoroughly or using repellents while outdoors at dawn or dusk. Local water is generally safe, though filtering or boiling is advisable when unsure. Urban tap water is treated and nearly always safe. When exceptions occasionally arise, there are public warnings or radio and print media warnings. Contaminated food is uncommon, though on occasion, mature reef fish can contain mild neurotoxins they accumulate in their bodies from freshwater algaes that wash into the ocean. The effects of such "fish-poisoning" are usually intense for only a day or two, but tingling lips and unusual sensitivities to hot and cold can linger for a long time.
Drownings are common, and automobile and other motor vehicle accidents often involving animals or pedestrians are very common. Local emergency medical care is very good on the basics in urban areas. Expect long waits in government-run clinics and hospitals. Treatment for serious conditions often requires an evacuation to New Zealand or Australia. Even the most basic medical care is usually not available outside of urban areas.
Fiji, like most of the South Pacific, can have intense solar radiation that can cause severe skin-burns in a short amount of time. Be sure to use hats, sunglasses and liberal amounts of high-SPF value sunblock on ALL exposed skin including ears, noses and tops-of-feet when out in the sun. On top of that tropical boils are a common inconvenience in Fiji, this can be avoided by giving those sweaty sections of the body a soapy scrub more than once a day.
English is an official language and is the language of instruction in education, and is spoken by most in Nadi, Suva and any other major tourist area. On a few of the less touristy islands, English may be spoken with some difficulty. Fijian or Hindustani Hindi/Urdu is spoken by most adults and children, and learning even a few key phrases will help you gain the respect of the locals.
Public phones are numerous and usually easy to find look around shops. All phones are prepaid - you must first purchase scrape-off code card F$5, F$10 or more nominals. Calling is done by calling card issuer center, entering the code found on the card and entering the destination number. Foreign call to Europe is approx. F$1 per minute.
Fiji, like many Pacific Island states, has a strong Christian moral society; having been colonised and converted to Christianity by missionaries during the 19th century. Do not be surprised if shops and other businesses are closed on Sunday. The Sabbath starts at 6PM the day before, and some businesses celebrate the Sabbath on a Saturday instead of a Sunday. Many Indians are Hindu or Muslim.
Also, dress modestly and appropriately. While Fiji is a tropical country, beach-wear should be confined to the beach. Take your cues from the locals as to what they consider appropriate dress for the occasion. When visiting towns and villages, you should be sure to cover your shoulders and wear shorts or sulus sarongs that cover your knees both genders. This is especially true for visiting a church, although locals will often lend you a sulu for a church visit.
