About Barrier Reef
Barrier Reef was an Australian television series that was first screened in 1971. Barrier Reef centred around a group of marine biologists on board a ship called the New Endeavour, researching around the Great Barrier Reef, off Queensland, Australia. "It was the first series in the world to feature extensive colour underwater filming on location". It was also a unique location for a TV show. The Great Barrier Reef is "The only living organic collective visible from Earth's orbit."
