I am sorry to say that there is no h2o just add water season 4. Although there are rumors that they will start filming season 4 in November 2012. But don't take my word for it cause they might just be rumors.
Nowhere. H2O: Just Add Water only has three seasons. Fans often speak of season 4, but it does not exist. Instead we have the new series Mako: Island of Secrets.
No, because there will not be a fourth season of H2O.
season 4 has not yet been released, so you can't watch it online, but it should be shown on tv later 2011, or begining 2012
There is no season 4 however, there was a spinoff series called Mako Mermaids.The three seasons of H2O & the three seasons of Mako Mermaids are currently (August 2015) streaming on Netflix.
no there is a season 5
Never, because there will not be a fourth season of H2O.
