This 19-day expedition travels from Taipei to Darwin, following a route through the islands of the Philippines and Indonesia. Crossing the Tropic of Cancer and the Equator, the journey combines tropical coastlines and coral reefs with endemic wildlife, local communities and the history and cultures of the region. Begin in Taiwan before travelling south through the remote islands of the Philippines. Explore the landscapes of Calayan Island, Divilacan Bay and the Caramoan Peninsula, visit Bohol's distinctive Chocolate Hills and search for wildlife including the Philippine Tarsier. There are regular opportunities to swim and snorkel, alongside Zodiac excursions, forest walks and visits to local communities. Continuing into Indonesia, explore Tangkoko Nature Reserve in search of Crested Black Macaques and tarsiers, and travel by local boat at Gorontalo where there may be an opportunity to swim and snorkel with Whale Sharks. Further south, the route takes in the forests and reefs of Seho and Taliabu, the endemic wildlife of Buru Island and historic Banda Neira, once at the centre of the global nutmeg trade. The final island visit is Kei Kecil, on the edge of the Coral Triangle, with its long beaches and extensive fringing reefs, before crossing the Timor Sea to Darwin.

Later, continue to Taliabu Island and the township of Bobong, with plans to visit local markets and spice plantations and gain an insight into everyday life on the island.
Day 15
Buru Island
Buru lies near the boundary between the Asian and Australasian biogeographic regions and supports a high proportion of endemic wildlife, including ten endemic bird species and four endemic mammals. Explore with the expedition naturalists and local guides, with opportunities to walk through forest in search of wildlife and visit local communities.
Day 16
Banda Neira
Explore Banda Neira, part of the small volcanic Banda Islands and once at the centre of the global nutmeg trade. Its historic buildings provide a reminder of the islands' complex colonial history, including Fort Belgica, constructed by the Dutch East India Company in the early 17th century. Across the harbour rises the volcanic cone of Gunung Banda Api, while beneath the water the islands sit within the Coral Triangle and are surrounded by extensive coral habitat. Depending on conditions, the day may combine historical exploration, village visits and time on or in the water. There may also be an opportunity to see Banda's traditional Kora-Kora canoes.

There should also be opportunities to snorkel, with the surrounding reefs supporting reef fish, nudibranchs, cephalopods, Dogtooth Tuna and rays.
