The Houtman Abrolhos archipelago, commonly known as simply the Abrolhos, is made up of over 100 islands and coral reefs off the coast of Geraldton, and provides a rich habitat for sea lions, green turtles, wallabies, carpet pythons and a fantastic array of bird life.

The Lacepede Islands, situated just off Australia’s Kimberley coast, are a fantastic destination for birding enthusiasts, supporting over 1% of the world’s population of brown boobies and roseate terns. Other bird species here include masked boobies, Australian pelicans and lesser frigatebirds, and it’s also a key breeding site for green turtles.

Talbot Bay is home to one of the world’s most unusual natural wonders, the ‘Horizontal Falls’. This amazing spectacle occurs when tidal movements force water through the narrow gaps in the ridges either side of Poulton Creek, with the water building up on one side quicker than it can flow through the gap, causing a spectacular waterfall effect.

Wyndham is the oldest major settlement in the Kimberley region, a former gold rush town surrounded by mangrove swamps and mudflats. The town is also the gateway to the remarkable Bungle Bungle mountains, known to the local aborigines for centuries but only ‘discovered’ by the outside world in the 1980s.

More of a large town than a city, Darwin is less about what’s contained within the city limits and more about the huge expanse of wild landscape that’s outside it. Closer to Jakarta than Sydney, the city really does feel remote in its tropical perch.

Thursday Island is one of the Torres Strait Islands, situated to the north of Cape York. Proximity to Papua New Guinea makes for an interesting cultural mix, and the island has a fascinating military history. Be aware that swimming off the beautiful beaches is not recommended due to the presence of crocodiles and marine stingers.

Alotau is the capital of Milne Bay province, on the remote eastern tip of mainland Papua New Guinea. Milne Bay was the scene of heavy fighting during the Second World War, and today you can dive amongst the wreckage left behind. Alotau also serves as a base for visiting the nearby islands, including the fascinating Trobriand archipelago.

Fergusson Island is the largest of the D’Entrecasteaux Islands, with a landscape of volcanoes, mud pools, hot springs and geysers. The Dei Dei hot springs are particularly impressive, and you may spot locals cooking food in the boiling hot water using baskets made from palm and pandanus leaves.

Dobu is a small island that belongs to the D’Entrecasteaux group, and was once feared by outsiders as a hotbed for black magic. The island is also part of the Kula ring, a fascinating and unique ceremonial practice in which the inhabitants of 18 different islands exchange armbands and necklaces.

Looming over Rabaul is smouldering Mount Tavurvur, an active volcano that buried much of the city when it erupted in 1994, and which still periodically belches smoke and ash. Rabaul is also an appealing destination for history buffs, with several World War II sites still scattered with rusting wreckage.

The lush island of Santa Ana, also known as Owaraha, is home to just three villages, and visitors are usually welcomed to the island with traditional songs and dances. You will find a few stalls where you can buy locally-made souvenirs, and you can also snorkel in the surrounding lagoon.

Ambrym is known as the ‘Black Island’ due to its dark volcanic soil, with two active volcanoes, Mount Marum and Mount Benbow. The island is also known for its magic and sorcery, and for its traditional Rom dances, when locals don elaborate masks and costumes.

Champagne Beach is a stunning stretch of perfect white sand on the east coast of Espiritu Santo, the largest of Vanuatu’s islands. The beach is named after a bizarre natural phenomenon, in which gas escaping from volcanic rocks on the sea floor causes the water to bubble and fizz at low tide.

The sparsely populated Yasawa Islands are famous for their stunning beaches and hilly volcanic terrain. You can indulge in all the usual activities such as sunbathing and snorkelling, along with a visit to the unique Sawa-i-lau caves, accessible by swimming through an underwater tunnel.

Lautoka is Fiji’s second largest city, known as the ‘Sugar City’ due to its important role in the local sugarcane industry. The waterfront area is pleasant enough, but we’d recommend using Lautoka as a jumping off point to visit some of the smaller surrounding islands, or the forests and waterfalls of the interior.

Levuka, on the little island of Ovalau, was the first capital of Fiji, and it was here that the Deed of Cession was signed in 1874, formalising the British annexation of Fiji. The port’s historic centre is a UNESCO World Heritage Site, with a number of well-preserved buildings dating back to the late 19th century.

Leleuvia is a small coral island, home to a laid-back resort and not much else. The colourful reef is easily accessible from the island’s western beach, home to marine life including tuna, barracuda, manta rays and turtles, while bird species recorded here include sacred kingfishers, swallows and orange-breasted honeyeaters.

The Lau Islands are found at the eastern edge of Fiji, a string of some 60 largely undeveloped islands and islets with a culture strongly influenced by neighbouring Tonga. Just off the coast of Vanua Balavu is the beautiful Bay of Islands, where you can enjoy fantastic snorkelling in the turquoise lagoon.

Close your eyes, imagine a South Pacific island, and you’re probably picturing somewhere like Uoleva. This quintessential desert island has no roads and no shops, just dazzling white sands, gently swaying coconut palms and shallow turquoise waters where you can snorkel amongst the thriving reefs.

Neiafu is the second largest city in Tonga and the capital of the Vava’u group of islands, situated next to the deep water Port of Refuge. Humpback whales pass through here between June and November, while on land the ‘Ene’io Botanical Garden is well worth a visit.

The sleepy island of Aitutaki is big on natural beauty, thanks to its stunning reef-enclosed lagoon. It’s also a deeply spiritual place: in the village of Arutanga you’ll find the oldest church in the Cook Islands, dating back to 1829, and services here are a spellbinding spectacle, with hymns featuring unaccompanied four-part harmonies.

Palmerston is a sleepy coral atoll with an unusual history, home to just three families, all descended from a single man. William Marsters, a ship’s carpenter from Gloucestershire, arrived on the island in 1863, and fathered a number of children with three different Polynesian wives.

Bora Bora is the very definition of idyllic, a diminutive Polynesian island dominated by rainforest-clad volcanic peaks, overlooking an electric blue lagoon ringed by coral reefs. The beaches and over-water bungalows are particularly popular with honeymooners, and the clear waters of the lagoon are perfect for snorkelling.

Raiatea, the second largest of the Society Islands, played a vital role in the development of Polynesian culture; it was from this island that settlers departed for Hawaii and New Zealand over a millennium ago. The island feels wilder than Tahiti, with steep, jungle-covered mountains, cascading waterfalls and ancient Polynesian temples.

Papeete is the capital of French Polynesia, situated on the northwest coast of Tahiti. The port is not the most magical spot, so we advise venturing forth to luxuriate in the turquoise lagoons, relax on the white sand beaches fringed with palm trees, and explore the rugged mountain peaks.

The Fakarava atoll surrounds a deep lagoon in the west of the Tuamotu island group, scarcely populated and home to a host of rare wildlife. The entire atoll has been declared a UNESCO biosphere reserve, and the shallow coastal waters make for excellent snorkelling.

Hiva Oa is the last resting place of the artist Paul Gauguin, who spent the final years of his life here, and the Gauguin museum in Atuona documents his time in the South Pacific. This beautiful island is also home to some evocative archaeological sites, including ancient petroglyphs and stone tiki statues.

Remote and unspoilt Fatu Hiva is the southernmost of the Marquesas island group, known for its tapa bark paintings and wood carvings. There are just two settlements on the island: the village of Omoa has a church and a small museum, while Hanavave lies on the staggeringly beautiful Bay of Virgins.

Mangareva is the largest of the Gambier Islands, over 1,000 miles to the south east of Tahiti, and is set on a beautiful lagoon used by the locals to farm black pearls. Don’t miss the 19th-century St Michael’s Cathedral, famous for its intricate altar decorated with mother of pearl shells.

The remote South Pacific island of Pitcairn was settled by a party of British sailors and Tahitians following the famous mutiny on the HMS Bounty in 1789, and their descendants still live on the island. The tiny capital, Adamstown, has a population of around 50 people.

The enigmatic moai statues of Rapa Nui (Easter Island) remain one of the world’s most intriguing archaeological mysteries. Descendants of the Polynesian settlers who carved them still live here, though these days the island belongs to Chile, despite being separated from the mainland by over 2,000 miles of Pacific Ocean.

Situated 400 miles off the coast of mainland Chile, Robinson Crusoe Island is part of the Juan Fernández archipelago, a UNESCO World Biosphere Reserve. The sailor Alexander Selkirk was marooned here from 1704 to 1709, and his story is thought to have inspired Daniel Defoe’s famous novel.
