The archipelago of "The Friendly Islands" was united into a Polynesian kingdom in 1845. It became a constitutional monarchy in 1875 and a British protectorate in 1900. Tonga acquired its independence in 1970 and became a member of the Commonwealth of Nations. It remains the only monarchy in the Pacific.

The preventive measures you need to take while traveling in this region depend on the areas you visit and the length of time you stay. You should observe the precautions listed in this document in most areas of this region. However, in highly developed areas of Australia and New Zealand, you should observe health precautions similar to those that would apply while traveling in the United States.
Travelers diarrhea, the number one illness in travelers, can be caused by viruses, bacteria, or parasites, which can contaminate food or water. Infections may cause diarrhea and vomiting (E. coli, Salmonella, cholera, and parasites), fever (Typhoid fever and toxoplasmosis), or liver damage (hepatitis). Make sure your food and drinking water are safe.
Malaria is a serious, but preventable infection that can be fatal. Prevent this deadly disease by seeing your health care provider for a prescription antimalarial drug and by protecting yourself against mosquito bites.
All travelers to malaria-risk areas in Papua New Guinea, the Solomon Islands, and Vanuatu, including infants, children, and former residents of these countries should take an antimalarial drug. Papua New Guinea has risk in all areas under the elevation of 1800 meters (5906 feet). The Solomon Islands has risk in all areas, except for the southern province of Rennell Island and Bellona Island. Vanuatu has risk throughout all its islands. The other countries pictured do not have a risk of malaria.
Dengue, filariasis, Ross River virus, and Murray Valley encephalitis are diseases carried by insects that also occur in this region. Protecting yourself against insect bites will help to prevent these diseases.
There is no risk for yellow fever in Australia and the South Pacific. A certificate of yellow fever vaccination may be required for entry into certain of these countries if you are coming from countries in South America or sub-Saharan Africa. For detailed information, see Comprehensive Yellow Fever Vaccination Requirements. Also, find the nearest authorized U.S. yellow fever vaccine center.
CDC recommends the following vaccines (as appropriate for age):
See your doctor at least 46 weeks before your trip to allow time for shots to take effect.
- Hepatitis A or immune globulin (IG) (except for Australia and New Zealand).
- Rabies, if you might be exposed to wild or domestic animals through your work or recreation.
- Typhoid (except for Australia and New Zealand), particularly if you are visiting developing countries in this region.
- As needed, booster doses for tetanus-diphtheria and measles, and a one-time dose of polio for adults. Hepatitis B vaccine is now recommended for all infants and for children 1112 years of age who did not receive the series as infants.
- Drink only bottled or boiled water, or carbonated (bubbly) drinks in cans or bottles. Avoid tap water, fountain drinks, and ice cubes. If this is not possible, make water safer by BOTH filtering through an absolute 1-micron or less filter AND adding iodine tablets to the filtered water. Absolute 1-micron filters are found in camping/outdoor supply stores.
- If you visit an area where there is risk for malaria, take your malaria prevention medication before, during, and after travel, as directed. (See your doctor for a prescription.)
- Protect yourself from mosquito bites:
- Pay special attention to mosquito protection between dusk and dawn. This is when the type of mosquito whose bite transmits malaria is active.
- Wear long-sleeved shirts, long pants, and hats.
- Use insect repellents that contain DEET (diethylmethyltoluamide).
- Read and follow the directions and precautions on the product label.
- Apply insect repellent to exposed skin.
- Do not put repellent on wounds or broken skin.
- Do not breathe in, swallow, or get into the eyes (DEET is toxic if swallowed). If using a spray product, apply DEET to your face by spraying your hands and rubbing the product carefully over the face, avoiding eyes and mouth.
- Unless you are staying in air-conditioned or well-screened housing, purchase a bed net impregnated with the insecticide permethrin or deltamethrin. Or, spray the bed net with one of these insecticides if you are unable to find a pretreated bed net.
- DEET may be used on adults, children, and infants older than 2 months of age. Protect infants by using a carrier draped with mosquito netting with an elastic edge for a tight fit.
- Children under 10 years old should not apply insect repellent themselves. Do not apply to young children’s hands or around eyes and mouth.
- To prevent fungal and parasitic infections, keep feet clean and dry, and do not go barefoot.

Tonga's electrical current is 240/50 (volts/hz) and uses the plug adaptors listed to the right under Related Items. Many North American appliances are designed to operate only within the 100-125 volt range. These appliances will suffer damage if plugged into 220-250 volts without the proper transformer or converter.
To determine which plug adaptors you'll need and if you'll require a transformer or converter, use our Electrical Connection Wizard.
For a detailed discussion of international electrical standards, see our related article on Electrical and Phone Adaptation.
