Shiff. It first screened on Australia 's Network Ten and runs in syndication on channels in over 120 countries and has a worldwide audience of more than 250 million.

The girls are rescued and brought back to shore, where they return to their normal lives, until discovering their lives have become anything but normal. The girls find out that ten seconds after coming into contact with water they transform into mermaids. After further experimentation, the girls also discover they have supernatural powers over water. The trio enlist the help of Cleo 's friend Lewis McCartney to help them keep their secret. Everyday situations, such as bathing and dealing with rainy weather, become tricky as the girls struggle with their newfound abilities, which come with many advantages and disadvantages, while also trying to keep them a secret from everyone else, including their families. They soon adapt to their new abilities and lifestyles. Series two introduces Charlotte Watsford, a rival to Cleo, for dating Lewis shortly after Cleo had broken up with him. She gains mermaid powers and becomes the main antagonist of series two. She has all three of the mermaids ' powers. In the end, Charlotte loses both her powers and Lewis. Series three sees the departure of Emma, who has left to travel the world with her parents. A new character, Bella Hartley, is introduced and it is discovered that she has been a mermaid since the age of nine. Rikki and Cleo become friends with Bella, but are soon beset by a mysterious tentacle of water with a connection to Mako Island. A new boy, Will Benjamin, also arrives and becomes friends with the trio when he discovers that they are mermaids. The girls learn that Earth is in the path of a comet that could destroy the planet. Using their powers, they manage to stop the comet from colliding with Earth. Cast Main Cariba Heine as Rikki, the new girl in town at the start of the show, who tends to be aloof and rebellious. Her power is the ability to control heat in water, ranging from warming to boiling, which eventually grows to allow her to control fire and lightning. Heine appears in all series of the show, and makes a special guest appearance in the spin - off series Mako : Island of Secrets. Claire Holt as Emma ( series 1 -- 2 ), who has a confident and responsible, if somewhat controlling, personality. She has the ability to freeze water, and later develops the ability to control clouds, ice and snow. Holt appears in series one and two, but left the show at the end of series two to film Messengers 2 : The Scarecrow, with the character 's departure explained as travelling the world with her family. Phoebe Tonkin as Cleo, who at first is shy and a little awkward and does not like water, but eventually becomes outgoing and personable. She is able to control and mould the form of water, as well as increase or decrease the amount of water present. She is later able to control the wind. Tonkin appears in all series of the show. Angus McLaren as Lewis, Cleo 's childhood friend and later boyfriend who is academically gifted and thinks of himself as a scientist. He helps the girls keep their secret and works to understand how and why the girls transformed into mermaids. After appearing in both series one and two, McLaren left the show during the third series to begin filming Packed to the Rafters, but guest starred in the final episode of the show. Indiana Evans as Bella ( series 3 ), the new girl in series three. She is a singer and performs at Rikki 's cafe. Bella became a mermaid in the sea caves of Ireland when she was nine, and has the power to change water into gelatine and a crystalline substance. During the series, she and Will develop feelings for each other, and eventually become a couple. Luke Mitchell as Will ( series 3 ), a skilled swimmer and free - diver who is introduced in series three. While exploring Mako Island, he finds the moon pool and is attacked by the water, causing him to search for the cause of the strange event. He is Bella 's love interest and becomes closer to the girls once he discovers they are mermaids. Supporting Burgess Abernethy as Zane, who is the arrogant local bad boy. In series one, he becomes obsessed with discovering the identity of the mermaids after catching a glimpse of one. He later develops an on - again, off - again relationship with Rikki. At the end of series one, when he finds out she, Emma and Cleo are mermaids, he stops his obsessive behaviour to protect Rikki. In series three, he transforms the Juice Net cafe and goes into a business partnership with Rikki, naming the cafe after her. Brittany Byrnes as Charlotte ( series 2 ), the new girl who becomes the main antagonist of series two. She enjoys the arts and sciences, but can be controlling and manipulative. She comes into conflict with the girls, especially Cleo, when she begins to date Lewis subsequent to his break - up with Cleo. Upon transforming into a mermaid, she obtains all of the girls ' collective powers - clarified as being due to the fact that she was exposed to the transformation conditions on her own rather than the original three being present at the same time. She permanently loses her abilities after a confrontation with the trio. She does not return in series three. Craig Horner as Ash ( series 2 ), a keen equestrian and riding coach who appears during series two. He forms a relationship with Emma, but does not learn of her being a mermaid until the season finale, when Emma reveals her identity. Horner does not appear in series three due to filming Legend of the Seeker. Taryn Marler as Sophie ( series 3 ), an ambitious and driven character who becomes the main antagonist of series three. She is Will 's older sister and takes an immediate dislike to Bella because Sophie sees her as a threat to Will 's success as a free diver. She becomes a manager in Rikki 's cafe and does as much as possible to cause grief for the mermaids, including destroying Zane and Rikki 's relationship. She also tries to get her brother Will to go against Bella by saying she is a distraction.

The custom costumes took six months to build, with the tails and tops made from body casts and comprising individually hand - crafted scales. The finished product weighs between 12 and 15 kilograms ( 26 and 33 lb ). Inside the tail are leg straps where the girls are strapped up and then zipped up. Once in costume, the girls have to be lifted into the water. Attempts were made to minimise the on - screen visibility of the zips on the tails, such as adding extra scales and crafting a ridge of material around the length of the zip. The tail fin itself was designed with a foot pedal to assist the actresses with swimming. This, along with the fin, adds some 60 centimetres ( 2 ft ) to the length of the costume.
