To quote from Wikipedia: Originally the movie was filmed on location in the Northern Territory in Australia. The production process itself was a laborious process as the colour technique used, Gevacolor, could only be processed overseas in England. The film produced was fragile and heat-sensitive, which was a problem as the Northern Territory has a typically hot climate; film was stored in cool caves to protect it from deteriorating. The last roll of negative was destroyed in a plane crash on its way for developing in England and the scenes were re-shot at Kanangra Walls in the Blue Mountains west of Sydney.
The reviewer that said the film wasn't filmed on location is clearly wrong. It was only the last reel that was lost.
