Mako Mermaids Season 5 - What We Know So Far

Long before Disney decided to bring a certain famous mermaid to life in its upcoming live-action adaptation of The Little Mermaid, a little Australian show has been busy spinning its own mermaid tale. Mako Mermaids, the spin-off series of the teen drama staple H2O: Just Add Water, gives its mermaids legs — when on land — but keeps with the classic mermaid themes of conflicting feelings about being in water vs. on land, with the apparently so lovable humans. While H2O: Just Add Water centers on three human girls accidentally turning into mermaids, Mako Mermaids (titled Mako: Island of Secrets in Australia) returns to the mystical Mako Island to turn teenage boy Zac (Chai Hansen) into a merman.

However, it isn't so simple: The three young mermaids charged with guarding the moon pool from outsiders are then cast out by their pod for the mistake. They take to land to try and figure out how to take Zac's water powers and fish tail away, so they can earn their way back into their pod. Zac, meanwhile, must deal with the new fact that whenever he gets wet, he reveals his fishy nature.

Well, after four seasons, Zac is fully used to being a merman. So, what's next? Here's everything we know about season 5.

When is the release date of Mako Mermaids season 5?

There is no news yet as to whether or not Mako Mermaids will be renewed for a fifth season. In fact, 'fifth season' is a bit of a misnomer — the show technically only has three seasons, but Netflix split season 2 into two parts, so the numbers read differently on Netflix compared to other places. However, none of that matters if the series isn't renewed for additional episodes.

News on that front has been pretty quiet since the last episodes aired in 2016. Creator Jonathan M. Shiff, who also created H2O: Just Add Water, tweeted in 2015 that there would be a movie following season 4, but that film seems to be suspended indefinitely. Shiff, meanwhile, is busy producing The Bureau of Magical Things season 2, which just got a trailer.

If Mako Mermaids gains enough attention on Netflix, then perhaps it will come back with a whole new season.

Who is the cast of Mako Mermaids season 5?

While the first season focused on new merman Zac and the three mermaids, Sirena (Amy Ruffle), Nixie (Ivy Latimer), and Lyla (Lucy Fry), the cast expanded and changed over the seasons. Nixie and Lyla left, while mermaids Mimmi (Allie Bertram) and Ondina (Isabel Durant) became permanent fixtures of the series.

It's possible Mako Mermaids could get by with a few changes to its cast in a potential new season, as characters have come and gone, but lead Hansen would need to come back. Since Mako Mermaids' last season in 2016, he's been busy with roles on other series, including Shadowhunters and The New Legends of Monkey.

Alongside Hansen, fans could expect his girlfriend Evie (Gemma Forsyth) and long time friend Cam (Dominic Deutscher) to return, as well as his mermaid sister Mimmi and her new boyfriend Chris (Taylor Glockner). Perhaps they would bring in a guest star from H2O: Just Add Water, like they did near the end of season 4 with Rikki (The Secrets She Keeps' Cariba Heine).

What is the plot of Mako Mermaids season 5?

Season 4 ended with the revelation that the water dragon threatening them was actually Zac and Mimmi's mother, Nerissa (Tasneem Roc), magically cursed into that form. With her entrance into the series, a fifth season would have plenty of material to navigate as to her relationship with her children. Additionally, it only seems natural that the series would then dive into the history with their father, and possibly bring him back too.

Undoubtedly, the writers could explore conflict between Nerissa and the pod, with an added magical twist to the story. There's more story to explore with the mermen, especially once Zac and Mimmi learn more from Nerissa. However, as the characters are mermaids in Australia, an interesting angle to take would be a more environmentally focused storyline. It would certainly make the series more timely and relevant to the current year.

For now, fans will have to tell all their friends to watch Mako Mermaids on Netflix, to let them know that people want a fifth season.
