The Popular TV Show H2O Just add water saw a spinoff Mako: Island of Secrets.The spinoff was not as popular as the original series but it did gained a dedicated fan following. The show began in 2013 and ran for four seasons up until 2016.
The final season ended in 2016 but it left a lot of questions unanswered. Ever since then fans are wondering if Netflix will renew the fan favourite show for another season.
Now the wait is over as Julia Adams one of the executive producers of the show has tweeted (in February 2020) that the Mako Islands has been renewed for a fifth and final season.
The final Season of Mako Islan will enter into production stage later this year and we might see it premiere on Netflix by Fall of 2021.
