South Pacific islands: how to tell them apart

5 places · Updated 4 November 2026

These five island countries lie in the South Pacific, south of the equator and north-east of Australia. Samoa, Tonga and Tuvalu are Polynesian, with languages that sound alike and share words such as "fale" (house). Vanuatu and the Solomon Islands are Melanesian: bigger, more mountainous island groups where English-based creoles are spoken alongside many local languages.

Start with the side of the road. Vanuatu is the only one where traffic keeps to the right. The other four all drive on the left.

Next, think about height. Tuvalu is a set of tiny atolls, never more than a few metres above the sea. Tonga's main island is flat too, but it is solid farmland rather than a thin strip of sand. Samoa, Vanuatu and the Solomon Islands are high volcanic islands, thick with rainforest.

Finally, read the words. Written Samoan hardly ever uses h or k, so "Talofa" (hello) and "Fa'afetai" (thank you) point to Samoa, or to Tuvalu, which also says "talofa". Tongan is full of h and k, as in "Mālō e lelei" (hello). In Vanuatu, Bislama looks like English spelled the way it sounds, such as "tank yu tumas", and in the Solomons, Pijin works in a similar way, with "tanggio" for thank you.

At a glance

🇼🇸 Samoa

Samoa is a Polynesian country of two large volcanic islands, Upolu and Savai'i, plus a few small ones. Villages of open-sided fale houses and big painted churches sit along coastal roads, backed by green mountains. Traffic drives on the left, which sets it apart from American Samoa next door.

Language and signs

Samoan is spoken everywhere and appears on many signs next to English. It uses lots of vowels and an apostrophe-like mark for a short catch in the voice, as in Savai'i and Fa'afetai. Look for "Talofa" (hello) and "Afio mai" (welcome).

Roads

Traffic drives on the left. A main road loops around each island near the coast, and on Upolu several cross-island roads climb over the central mountains. Brightly painted buses, many with wooden bodies and names on the front, link the villages with the capital, Apia.

Landscape and towns

Both main islands are volcanic, with a forested, cloud-topped spine and lower slopes of coconut palms, taro and bananas. Upolu has waterfalls and deep pools. Savai'i is bigger but quieter, and in its north the road crosses wide fields of black lava from eruptions over a century ago. Beaches are mostly white coral sand inside sheltered reefs.

Apia is a small, relaxed harbour town of low buildings, markets and government offices. In villages, houses face a central green called the malae. A traditional fale has a rounded roof on wooden posts and no walls, so breezes blow straight through. Each village usually has at least one large church, often white or brightly painted.

Easily confused with

• American Samoa: American Samoa shares the language, fale and colourful buses, but drives on the right and uses American road signs. If cars are on the left, you are in Samoa.
• Tonga: Tonga's main island is flat, while Samoa has mountains behind almost every village. Tongan words are full of h and k, letters that written Samoan rarely uses.

Did you know? In 2009, Samoa switched from driving on the right to the left, partly so people could buy cars more cheaply from nearby countries such as New Zealand and Australia.

🇹🇴 Tonga

Tonga is the only Pacific island nation with its own king, and it is made up of about 170 islands. Most people live on Tongatapu, a flat island of farmland, villages and coconut palms around the capital, Nuku'alofa. Look for low green countryside, pigs wandering by the road, big churches and Tongan words full of h, k and apostrophes.

Language and signs

Tongan and English are both used on signs. Tongan words often contain h, k and "ng", plus an apostrophe-like mark for a break in the voice, as in Nuku'alofa, Ha'apai and Vava'u. "Mālō e lelei" means hello, and "mālō" on its own means thank you.

Roads

Traffic keeps to the left. Tongatapu has a web of mostly flat, fairly straight roads crossing farmland between villages. Outside Nuku'alofa, many roads are narrow, and drivers slow down for pigs, dogs and chickens crossing.

Landscape and towns

Tongatapu is a raised coral island, low and flat, with a shallow lagoon on its northern side and cliffs and blowholes along its southern coast. Its fertile soil grows yams, taro, cassava and squash, with coconut palms everywhere. Other island groups differ: Vava'u is hilly, with a deep, winding harbour, and 'Eua is higher and forested.

Nuku'alofa is a low, spread-out town by the sea, with markets, shops and the royal palace, a white wooden building with a red roof. Village houses are usually small, built of concrete or timber with metal roofs. Churches are large and often grand, and on Sundays almost everything closes while people go to church and rest.

Easily confused with

• Samoa: Samoa has steep green mountains behind most villages, while Tongatapu is flat. Samoan writing has almost no h or k, so a name like Ha'apai or Kolonga is Tongan.
• Fiji: Fiji is more mountainous and busier, with sugar cane fields and Hindu temples. Tonga's flat fields of root crops and roadside pigs look quite different.

Did you know? Near the village of Niutōua stands the Ha'amonga 'a Maui, a giant stone gateway built around 800 years ago from three huge blocks of coral rock.

🇹🇻 Tuvalu

Tuvalu is one of the smallest countries on Earth: nine tiny coral islands and atolls with only about 26 square kilometres of land in total. Most people live on Fongafale, the main islet of Funafuti atoll, a ribbon of land so thin that the sea is almost always in view on both sides.

Language and signs

Tuvaluan is the everyday language and English is used on official signs. Tuvaluan is close to Samoan and shares the greeting "Talofa", but says "fakafetai" for thank you, with a k where Samoan has an apostrophe.

Roads

Traffic keeps to the left. Fongafale has one main road running much of its length. Cars are few; most people ride motorbikes or scooters. The airport runway takes up a large part of the islet, and when no planes are due, people use it for football, volleyball and evening strolls.

Landscape and towns

There are no hills at all: the highest ground is only about four or five metres above the sea. Coconut palms, pandanus and breadfruit grow in the sandy soil, and some families grow pulaka, a giant taro, in deep pits. The lagoon side is calm and turquoise, while the ocean side is a rough shore of broken coral.

Funafuti's houses are small and close together, usually single-storey concrete or timber buildings with metal roofs. Vaiaku, near the airport, has the main government building, a hotel and a few shops. Each island community has a large, open-sided meeting hall at its heart.

Easily confused with

• Kiribati: Kiribati's Tarawa looks very like Funafuti and also drives on the left, but is bigger and busier. Gilbertese has no f, l or s, letters Tuvaluan uses all the time.
• Marshall Islands: The Marshall Islands share the same flat atoll scenery, but drive on the right, and Marshallese uses unusual letters such as ļ and ā.

Did you know? The name Tuvalu means "eight standing together", after the country's eight traditionally inhabited islands. There are nine islands in all. Tuvalu's internet address ending, .tv, is popular with television and video websites, and renting it out earns money for the country.

🇻🇺 Vanuatu

Vanuatu is a Y-shaped chain of about 80 islands in Melanesia, east of northern Australia. The islands are volcanic and mountainous, wrapped in rainforest and coconut plantations. It is the only country in this group that drives on the right, and signs mix English, French and Bislama.

Language and signs

Bislama, the national language, is based on English but spelled the way it sounds: "tank yu tumas" means thank you very much, and "yumi" means all of us. English and French are also official, so shop and school signs can be in either.

Roads

Unlike its neighbours, Vanuatu drives on the right. On Efate, a sealed ring road loops all the way around the island, through villages, plantations and along coastal cliffs. In Port Vila, the streets are busy with minibuses that work as shared taxis. On smaller islands, most roads are unsealed.

Landscape and towns

The islands are tropical and green, with steep volcanic mountains, waterfalls and rivers. On Espiritu Santo, cattle graze beneath tall coconut palms. On Tanna, the active volcano Mount Yasur rumbles beside a plain of grey ash, and giant banyan trees spread their roots across the forest. Beaches can be white coral sand or black volcanic sand.

Port Vila wraps around a hilly bay, with shops, cafés, a big market hall and offices along the waterfront, and French and English names side by side. In villages, many houses are built from woven bamboo, palm leaves and timber, with thatched or metal roofs. Luganville, on Santo, has one long, very wide main street.

Easily confused with

• Solomon Islands: The Solomon Islands share the jungle-covered mountains and leaf-thatched houses, but drive on the left. French on shopfronts and Bislama spellings point to Vanuatu.
• Fiji: Fiji drives on the left and has sugar cane fields and Hindu temples. On a tropical island in this part of the Pacific with traffic on the right, think Vanuatu.

Did you know? On Pentecost Island, men leap from tall wooden towers with vines tied to their ankles. This land diving ceremony inspired the modern sport of bungee jumping.

🇸🇧 Solomon Islands

The Solomon Islands are a long double chain of hundreds of islands east of Papua New Guinea. The capital, Honiara, is on Guadalcanal, a large island with a rugged, forested mountain spine and grassy plains along its north coast. Traffic drives on the left and signs are in English.

Language and signs

English is the official language and is used on signs, but Solomons Pijin is what most people speak. Like Bislama, it is an English-based creole: "tanggio tumas" means thank you very much, and "stoa" means shop. Dozens of local languages are spoken too.

Roads

Drivers keep to the left. Honiara has one main road running along the coast through town, often busy with cars, trucks and minibuses. Beyond the town, roads follow the north coast of Guadalcanal, crossing rivers and passing palm plantations, and many turn to gravel. Other islands have only short stretches of road.

Landscape and towns

The islands are hot, humid and very green. Guadalcanal has steep mountains covered in rainforest, wide rivers running down to the sea, and open plains of tall grass and oil palm east of Honiara. Coconut palms line the shore, and mangroves fill sheltered bays. Many smaller islands are low and ringed by coral reefs and lagoons.

Honiara has a big central market, shops and offices along Mendana Avenue, its main street. Houses range from concrete with metal roofs to wooden homes on stilts. In villages, many homes are built from timber and woven sago palm leaves, raised off the ground to stay cool and dry.

Easily confused with

• Papua New Guinea: Papua New Guinea also drives on the left and has similar villages, but is far bigger, with high mountain valleys. Its creole, Tok Pisin, says "tenkyu" for thank you, where Solomons Pijin says "tanggio".
• Vanuatu: Vanuatu looks similar but drives on the right, with some French on signs. In the Solomons, traffic keeps left and French is absent.

Did you know? On the island of Malaita, people still make traditional shell money: long strings of tiny polished shell beads, used for important gifts and ceremonies.

Quick round-up: cars on the right in the tropical South Pacific mean Vanuatu. A flat, narrow atoll with motorbikes and a runway in town is Tuvalu. Flat but wide farmland, roadside pigs and Tongan words with h and k mean Tonga. Volcanic peaks, open fale and Samoan words with cars on the left mean Samoa. Big jungle islands, leaf houses and Pijin mean the Solomon Islands.
