The Hoga Island Marine Centre is based on a car and bike free island which is in the heart of the Wakatobi Marine National Park and is one of our most heavily published research sites. You will begin with some training, starting with the opportunity to complete a PADI Open Water dive training course if you would like to learn and aren’t already qualified, followed by a compulsory Indo-Pacific reef ecology course with practicals by diving or snorkelling. Once the Indo-Pacific reef ecology course has been completed you will then join the research teams and help them to collect data from the coral reefs around the island. This will include the opportunity to learn survey techniques including stereo-video surveys of reef fish, video surveys of benthic transects, behavioural studies on cleaner fish and seagrass ecology.

Indonesia - Wallacea Marine Research Objectives

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. 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 2021 season will complete this monitoring plus some additional projects.

  • Gain an internationally recognized SCUBA qualification
  • Option to undertake additional PADI dive qualifications above Open Water (additional cost)
  • Diving and snorkelling within some of the most diverse reefs in the world
  • Working alongside specialist marine scientists
  • Attend evening lectures given by the science team on marine ecology
  • Participation in the Reef Survey Techniques course
  • Learn a variety of survey and monitoring techniques for in-water data collection
  • Opwall fee
  • Cost of international flights into and out of Jakarta or Makassar
  • Cost of internal travel to and from the start and end point of the expedition, plus any hotels you might require. The standard package costs around £583 or $722 (Jakarta) or £368 or $455 (Makassar)
  • Extra nights’ accommodation in Jakarta or Makassar costs around £26 or $34 (breakfast included).
  • Park entrance fees are £25 or $33.
  • Visa costs of approx. £32 or $40 for a VOA for 30days. Approx. £110 for visa extension (31-60 days). Please get in touch with someone from Opwall for more detailed advice.
  • Dive equipment rental – £60 or $90 per week for a full dive kit. If you only wish to snorkel and want to hire snorkel equipment, the cost is £30 or $45 per week. Please note that wetsuits cannot be provided – you should bring your own.
  • PADI manual and PIC card (if you are completing your Open Water qualification) – £69 or $89 approx.
  • Vaccinations and prophylactic medicines – cost can vary depending on your healthcare provider.
  • Spending money for snacks/drinks/laundry – Indonesian rupiah only
  • All prices in GBP or USD unless specified

Most of our volunteers fundraise for their expedition costs. Find out more.



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.

Creature comforts

Facilities at Pantai Nirwana are very comfortable; shared dorm rooms have beds with a mattress, stand-up showers, and Western style toilets.

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.
