Bradley Morahan (James Mason) is an Australian artist who feels he has become jaded by success and life in New York City. He decides that he needs to regain the edge he had as a young artist and returns to Australia. Once there, he sets up in a shack on the shore of a small, sparsely-inhabited island on the Great Barrier Reef were he meets up with young Cora Ryan (Helen Mirren). To help her save enough money to fulfill her dream of becoming a hairdresser in Brisbane, he pays her to be his model. She reinvigorates him, becoming his artistic muse.
This is a slowed down underwater scene I edited from the movie.
