Here are a list of do’s and don’ts. They may not be absolutely necessary but they will make your trip that much more enjoyable.

• Learn a little of the language; it tickles the locals sense of humour.
• Some dive resorts have a small boutique gift shop but if you want snack foods to eat you’d be best to take them with you.
• Take a newspaper and perhaps womens magazines to read - and pass on to management when you’ve finished!
• Be aware that alcohol, cigarettes and skimpy clothing may offend. 
• Dress modestly when visiting local villages. Don't wear shorts, and women must not wear halter tops and shoulders bare. Do not wear hats. They are interpreted as a sign of disrespect. Always remove your shoes before entering any house or other building in a village.
• Take a small backpack to keep your camera in. If staying in an air conditioned room, keep your camera box open as the camera will fog up and can cause long term problems.
• Take an extra water bottle; dehydration can be a big problem.  The water is  usually safe to drink at dive resorts, but check first!
• Take a wide brimmed hat, sun cream and basic first aid kit containing antibiotic cream.
• Small gifts for the local kids, especially anything made of plastic, such as a yoyo, will earn you a life long friend.
• Take a torch and mosquito coils with you.
• Eat locally and eat what is natural to the area.

Be courteous to a fault and show respect. Speak softly. Raised voices are interpreted as expressing anger.

USEFUL INFORMATION

Religion
Christianity forms the main religion of the Kingdom, and the island represents most of the denominations, with many churches dotted throughout the islands. Sunday is the traditional day of rest, a fact well observed in Tonga. You will find only hotels, a few restaurants, and tour operators open for business. However Sunday is still an interesting time to walk the streets listening to the beautiful singing, which can be heard as you wander past the churches. Visitors are welcome in churches but it is important to understand the practices and rules within the churches.

Language
Tongan is the national language, although English is widely spoken and learned. Tongan is a West Polynesian language that belongs to the Oceanic branch of Austronesian languages. With only 12 consonants in the language and 16 letters in total, learning is a great experience.

Electricity
Electricity in Tonga is 240V AC, 50hz. The plugs are the same as in New Zealand and Australia. US Appliances will require a power converter.
