This expedition is based on Hoga Island in the Wakatobi Marine National Park where upwards of 120 marine biologists and students are based for an eight week season each year. If you want to gain your Divemaster qualification at a site where everyone is interested in and working on marine biology projects, then this is an ideal location. To qualify for this training you need to be Rescue Diver qualified and have completed at least 40 dives. Over the course of the four weeks you will be helping to train and provide in-water support to new divers and those completing marine projects. During this expedition you should complete at least 40 dives on some of the most biodiverse reefs in the world.
There is a triangle of reefs in Eastern Indonesia that have the highest diversity of hard coral genera, the proxy commonly used to assess overall diversity of coral reefs, anywhere in the world. Both the marine stations being used by the Opwall teams are in the centre of this triangle. The South Buton Marine Centre has established a series of standard monitoring sites on reefs south of Bau Bau and around the surrounding small islands, with the objective being to use the data to develop plans for conserving these reefs. The Hoga Island Marine Station is located in the heart of the Wakatobi Marine National Park. Over the last 20 years, a series of scientists have been based at this site during the Opwall survey seasons and as a result, this is now the most published site in the Coral Triangle. For the last 15 years a series of constant monitoring sites around Hoga and eastern Kaledupa have been monitored for macroinvertebrates, fish communities, coral cover and community structure. The 2020 season will complete this monitoring plus some additional projects.

At the marine sites during the day, the weather is normally sunny and warm (around 30 degrees Celsius), and the night temperatures drop to around 20-25 degrees Celsius. Being on the coast means there is often a pleasant breeze so it does not always feel this hot. It rains rarely, but when it does it tends to be very heavy for short periods of time.
Fitness level required
Low-Moderate. Some fitness is required for in water activities, but conditions are relatively easy.
The Hoga Island Marine Station is an established facility that lies within the Wakatobi Marine Park of eastern Indonesia. The station was rebuilt in 2016 and supports a dive centre, lecture theatre, wet-lab as well as a large dining room and kitchen facility. Simple huts owned by members of the local fishing community surround the station and serve as guest accommodation. The island supports reliable phone signal that allows limited internet access.
