Yes, there will be a Season 4. Emma, Cleo, Rikki, Bella, Will, and Lewis, will be the characters in it. I don't know what it is going to be about, but it will premiere February 2011. I am so glad that they will come out with Season 4! I can't wait to see it! I do not live in Australia I live in the USA, but I will do everything I can to watch it!

for sweetrae...You don´t live in Austarlia, same here, I live in Estonia...and I will do anything to see that 4th season too...It´s the greatest news what I have heard today...really thanks that you said that...I wouldn´t know,, but now I know..AND I am really happy that it finally comes out....love h2o just add water 4ever..;)

but do u know for sure sweetrae ?

HEY H2O SEASON 4 WILL BE 1000000000%%.I KNOW THAT MAYBE SHOOTS STARTED IN 16 OCTOBER,2010.MAYBE CLEO LIVED H2O.EMMA RETURNS.AND MAYBE WILL BE NEW MERMAID IN REAL LIFE HER NAME IS ANALLY AND IN REAL LIFE SHE COSIN OF PHOEBE TONKIN.I KNOW ONLY THISS.I DON'T KNOW ITS TRUE OR NOT BUT SEASON 4 WIL BE 1000000%%

i read that clio is leaving, she will be in 4 chapters of the 4th season, Will'll be leaving also, there will be a 4th mermaid (Kelly, Hannah Murray),nobody knows wether bella will stay (but if the director is saying there will be there 4 mermaids, then i can assure bella have higher possibilities to stay, u know... because cleo is leaving), and at last Kim (the younger sister of cleo) will be leaving too.
Note: I'm from mexico and don't have any way to see h2o if it's not in internet :(

I'm quite confused on whether there is a season 4 or not. It's REALLY annoying how it's back and fourth. Some people think there will be and others not. I myself, I live in the US. The last episode I remember seeing is one in season 2. Then they cut it off for no reason with absolutely NO warning.
One day I was thinking about the show and took to the internet for help. I found a great website. (Google search 'h2o just add water' and it should be the first link that's NOT a video. The website is called TV Blinkx.) I watched an episode everyday until I was done. I hope that whenever the 4th season DOES come out, that someone posts it on this site. I check daily for anything new.
The only advice I can give is to STAY POSITIVE. See if you can email the producers or creator or something and tell them YOUR story. If we flood them with emails, they'll see how much we want another season and make it. Make sure to post that you're from the US (if you are) and maybe they'll even bring it back here again.
Thanks for reading. :D

Idk is there or not?

@ h2o-clewis
Let me know if you ever find out.....

There is 100% going to be a season 4. Hannah Murray is not in it. I asked Aussie TV mag TV Week if there was going to be a 4th season and they said yes there is but they don't know when it will air, hopefully it airs sometime this year. More info will be released closer to the air date.

yay you've just made my day!

awesome
but who did u ask?

aquazula, Hannah Murray is not in season 4, it's all just rumours, don't believe what is on wikipedia, it can be edited by anyone. Phoebe Tonkin is not leaving, more stupid rumours, don;t believe any of them. I just read an interview with Hannah, she was asked what she was up to and she never mentioned H20, all rumours.
