Filming for the series began at
Hayman Island in September 1969. The show was almost entirely filmed in North Queensland and at the time the show was reported to be the most expensive series ever produced in Australia and one of the few Australian series to be produced outside Sydney or Melbourne.
Barrier Reef was produced by Fauna Productions who also created the uniquely Australian hit TV series
Skippy the Bush Kangaroo, using some of the same crew and cast members. Like the
Skippy series,
Barrier Reef showcased iconic Australian locations in colour film as the series was intended for an international audience (despite Australia not broadcasting colour television at that time). The show was screened in many countries across the world, giving international audiences a glimpse of what the stereotypical Australia was like. The show was originally called
Minus 5. ==Reception==
