However, due to popular demand by fans, they relented and made one more season with only Kate Bell returning in a main role.

It starred Adam Saunders as Heath (the relaxed joker who struggles with school), Tahyna Tozzi as Perri (resident glamour queen from the Gold Coast), Sophie Luck as Fly (the youngest), Kate Bell as Bec (the local), Khan Chittenden as Edge (the aggressive and competitive teenager), Chris Foy as Matt (the generic 'smart guy') and Mara Scherzinger as Anna (a famous German kiteboarder).

Filming of a second season began in early January 2006 in Sydney, with a revised cast, which included Sophie Luck (who was back as Fly), Adam Saunders as Heath (who leaves in episode six) and Trent Dalzell as Corey, Ryan Corr as Eric, Lesley Anne Mitchell as Brooke, Taryn Marler as Rachel, Gabrielle Scollay as Amy, and James Sorensen as Mike.

Sophie Luck, Adam Saunders, Kate Bell, Chris Foy, Tahyna Tozzi, Nadine Garner and Khan Chittenden have all reappeared in the second season in various episodes.

The new Solar Blue pupils are Guy (Kain O'Keeffe), Charley (Lachlan Buchanan), Adam (Eka Darville), Bridget (Cariba Heine), Loren (Amy Beckwith) and Cassie (Rebecca Breeds).

In South Africa, Blue Water High was aired twice a week on Go on the local satellite system, DSTV.

After DSTV added more MNET channels, Blue Water High started airing every weekday at 19:30 on Magic World 112 from 1 July 2010.

In Portugal, SIC also bought the first season, and it aired in the country from Monday to Friday at 5pm in Summer 2009; the show was named Mar Azul ("Blue Sea").
