Ansett was the first Australian airline to move into the package holiday business. In 1947, Ansett started offering services to resorts on the Great Barrier Reef using Catalina flying boats. These services established the Great Barrier Reef as a destination for tourists. ATI subsequently took over its rival, Barrier Reef Airways. Ansett developed Hayman Island into a major holiday resort in the Whitsunday region. BRA's Short S.25 Sandringham flying boats were later used by Ansett Flying Boat Services on the Sydney-Lord Howe Island route. The service, from Rose Bay Base on Sydney Harbour, was maintained until 1974.
