As the name suggests, Barrier Reef was an Aussie adventure series from 1971-1972 which was based around a group of marine biologists researching the Great Barrier Reef off the coast of Queensland in their boat, 'New Endeavor'.
They had the usual token babe (and what a babe!), they also had brilliant aqualong gear, re-breathers and underwater walkie talkies.
