Where is movie south pacific set?

The play is, they say, "set on two islands in the South Pacific" but it appears they're never mentioned by name in the script. It is based on the book "Tales of

Read >> The motion picture adaptation of Roger and Hammerstein's musical "South Pacific" was filmed on the island of Kauai using often peculiar color filters which distract from the beauty of the islands. The film has an all-star cast featuring Rossano Brazzi and Mitzi Gaynor in the lead roles. The film was nominated for three Academy Awards, but won only for Best Sound.
