Mako Island
Mako Island is a fictional island in the H2O: Just Add Water, Mako: Island of Secrets and H2O - Mermaid Adventures series. It is located approximately 50 km off the Gold Coast, Queensland, Australia.


Mako Island was formed after a comet crashed into the Earth. We know that one of the shards impacted near Ireland (Eire) forming the Sea Caves of Ireland. So other shards may have landed in other locations creating moon pools wherever they impacted. It is possible that these other moon pools could have also created mermaids all over the Earth in other places and other times. It's origin is revealed in season 3. Mako Island has a magical sea cave at its base leading to the Moon Pool, where Cleo, Emma, and Rikki, and the former mermaids, Gracie, Louise, Julia, and Charlotte, got their mermaid powers. There is also a secondary cave leading to a waterfall outside. The waterfall is part of a stream running through a mangrove forest. Mako Island has been around long before humans walked the earth and it will still be around long after humans have gone. Around Mako there are the largest population of Mako sharks and sea turtles, some of which cannot be found anywhere else on earth.

Off-shore there are coral reef sands and a number of wrecks, including Miss Louise Chatham's boat the Lorelei. On the northern side of the island there is a place called Triton's Reef, its a known as place where sharks breed. Throughout history, there have been peculiar happenings around Mako, such as a whirlpool and numerous ship wrecks and disappearances, giving Mako an eerie reputation.


H2O: Just Add Water

Season 1

In 2000s, Cleo, Emma and Rikki accidentally go to Mako Island. While looking for a mobile signal, they fall into a cave, where they find the Moon Pool. The Full Moon rises, and aligns with the Moon Pool, releasing the magic in the water. The girls are transformed into mermaids. Days later Emma found a locket at the bottom of the Moon Pool, indicating that they were not the first to be there. Linda Denman, a marine biologist, arrives to Mako, in order to study the fish. She and her team discover the underwater cave that leads to Moon Pool. With the help of underwater cameras, Denman discovers that Cleo, Emma and Rikki are mermaids, and starts to chase them. Louise Chatham, an old woman, reveals that during a lunar eclipse, the Moon Pool will react to the moon magically and the mermaid that is in the pool when the eclipse occurs, will lose her powers. The girls deceive Dr. Denman, who believes that they have lost their powers forever, and leaves the city. After 12 hours the girls again change to mermaids when they come in contact with water.

When the Comet Eva returned to Earth in 2010, the whole island heated up like it was working as a normal volcano. That lead to very strange temperature rising, and the fish were fleeing from the vicinity of Mako Island. The comet entered the atmosphere on February 7th which was the same day when the water first attacked Cleo, Rikki, and Bella.
