H2O: Just Add Water H2O: Mermaid Adventures

Mako: Island of Secrets is an Australian television programme for children and teenagers created by Jonathan M. Shiff. Internationally released as Mako Mermaids, the show is a spin-off of H₂O: Just Add Water and is produced by Jonathan M. Shiff Productions in association with Network Ten, ZDF and Netflix, with assistance from Screen Australia and Screen Queensland.^[1][2]

The series follows Zac, a teenage boy who turns into a merman after accidentally falling into a magical pool of water on the fictional island of Mako.

Zac, a teenage boy, decides to camp on Mako Island, unaware that three mermaids, Lyla, Nixie, and Sirena, guardians of the island, are watching him. That night, when the full moon rises, the boy comes into contact with the magic water of the Moon Pool. The following morning, Zac discovers that he has the ability to control and manipulate water. Later, after accidentally falling into the water, he finds that he has also become a merman with a fish-like tail. His new-found merman abilities threaten to expose the existence of merpeople. After being cast out by their pod for allowing Zac to visit the island, the three mermaids, curious about living on land and motivated to remove Zac's powers, venture onto the land and learn to live among humans.

In series 2, the mermaids continue to discover Mako's secrets and learn more about the merman chamber. While Lyla and Nixie go in search of a new home, Sirena is left with Ondina and Mimmi, new mermaids who continue the effort to remove Zac's powers and reclaim the island for their pod. Evie, Zac's girlfriend, faces her own battles when she becomes a mermaid herself, and the others try to help her cope with the change. They also discover that Zac is a born merman and is Mimmi's brother.

In series 3, with Sirena away in Hawaii with her sister Aquata, Zac, Ondina and Mimmi are joined by Weilan, an Eastern mermaid who has fled to Mako for sanctuary from a magical water dragon. The mermaids discover that the dragon is Zac and Mimmi's long lost mother and must find a way to save her.

• Lucy Fry as Lyla (series 1), seen as the leader of the three mermaids. She is hot-headed, determined, but still very smart. Despite initially only being interested in him for the sake of removing his powers, she develops an attachment to Zac. She has left with Nixie to search for a new home for the pod in season 2.
• Ivy Latimer as Nixie (series 1), one of the three mermaids. She is an adventurous girl, who often gets into trouble and only does what she believes is right. In series 2, it is explained that she has left with Lyla to search for a new home for the mermaid pod.
• Amy Ruffle as Sirena (series 1–2), one of the three mermaids. Naive and sweet, she acts as a mediator and peacemaker when Lyla and Nixie quarrel.

While Cam is initially supportive of his friend and helps to keep his secret, he becomes jealous and envious of Zac's powers.

• Kerith Atkinson as Rita, the school principal and a mermaid. She left her pod years ago to be with a human boy she fell in love with, but who died before they could marry. She serves as a source of knowledge and history for the girls, and teaches them how to properly use their powers.
