Fiji Dive, Marine Conservation and Culture. For avid (though not necessarily experienced) fans of diving ages 18–35, the six-week program Fiji Dive, Marine Conservation and Culture combines cultural immersion, diving certification or advancement, and marine conservation work. Participants start with a certification or advancement course with KoroSun Dive. They spend a week living in a very basic village outside of town while learning how to conduct Marine Protection Area (MPA) research from the Jean-Michel Cousteau Resort's resident marine biologist. The second week or so is spent at Hidden Paradise Guesthouse while they begin research. The group then moves to a house in the area and continues its dive research. The last week or so of the trip is spent relaxing at either the Beach House or Mango Bay Resort on Viti Levu's Coral Coast. The program costs US$3,950. Six-week marine conservation internships involving a longer village stay are also available, as are one-three week luxury packages with an optional marine biology component. 970–7906; 643/357–0580 in NZ. www.diving-fiji.com.
