Ocean Girl (titled Ocean Odyssey on CBBC in the UK) is an Australian science fiction TV series aimed for family audiences and starring Marzena Godecki as the lead character.
The show is set in the near future, and focuses on an unusual girl named Neri who lives alone on an island, and the friendships she develops with the inhabitants of an underwater research facility called ORCA (Oceanic Research Centre of Australia). The show is an example of deep ecology science fiction.
Neri — the title character — is a young girl with an affinity for water, super-human strength, the ability to swim long distances, and super-human lung capacity. She lives alone on an otherwise deserted island. Early in the first season, Neri befriends two Australian boys: Jason and Brett Bates. This friendship is at first a highly-guarded secret due to Neri's fear of other humans. The Bates brothers live in an elaborate underwater research and environmental protection facility called ORCA, located near Port Douglas, Queensland. At the beginning of the series, they move to ORCA in order for their mother, Dr. Dianne Bates, to study whale song. A significant portion of the series takes place on ORCA itself, and looks at the activities of its inhabitants, many of whom are school-aged children, just as Jason and Brett.
As the series progresses, it is explained that Neri came to Earth on a spaceship with her father when she was young, though his death soon after leaves Neri to fend for herself. Prior to meeting Jason and Brett, Neri's only friend was a humpback whale (called jali in Neri's native tongue), whom she names "Charley", and with whom she can communicate. Later in the series, Neri's curiosity leads her to explore ORCA, while Dr. Bates' study of Charley's whale song helps her identify Neri as the intended recipient of that song. Eventually, Dr. Bates and her assistant, Dr. Winston Seth, become embroiled in Jason and Brett's effort to keep Neri a secret, while also performing numerous tests on Neri to understand how she's able to communicate with whales.
