Would like to see a merman in s4, and Zane&Rikki need to get back together. The Merman could be a love interest for one of the girls! Season 4 is being filmed now, and eps 1, 2, and 3 have been shot, but what with the editing process it could be 5-6 months before they are ready for TV. My guess is that the new series will be broadcast late 2011, probably Autumn time. Fingers crossed!

A season 4 has been confirmed by the channel 10 forum moderator. if anyone would know about a 4th season, it's the channel which airs it. It will probably air sometime around April.

so finally a season 4 has been confirmed.

where did you see that?

the official Neighbours site, the forum moderator.

Can you post a link?

No!!. There is no season 4 Its just rumors. It was officially over. I wish there was a season 4 with Charlotte in it!

H2O is amazing, but I'm not sure if there is going to be a season 4. I hope so! The thing is, you can't trust wikipedia or wikia because ANYONE can edit them, so they can put what they want.

phoebe tonkin's manager told me that they haven't gotten a call from the director for season 4 so she thinks there probably isnt going 2 be 1...

A season 4 is 100% confirmed by Aussie TV mag, TV Week, but they don't know when it will air. Hope sometime this year, with the current floods in Queensland, filming has been haulted for a few days. Phoebe Tonkin is not pregnant, whoever said that is telling a lie. Phoebe Tonkin recently starred in Home and Away as Adrian (Adrianna) and the film Tomorrow When The War Began.
