The Nine Network has joined the project as the Australian partner and co-producer of the three-part documentary, part of the acclaimed BBC Earth series, to be screened in 2012.

Cameraman and marine biologist Richard Fitzpatrick is the project's director of photography.

"It's the biggest series ever done on the reef, the most technology ever thrown at it," Fitzpatrick said.

"It goes from deep sea - we're filming a thousand meters down - way up to the mangroves and rainforest, saying how everything's interconnected."

Animation will explain the reef's creation and the series will present climate change threats.

"It will be the past, the present and a bit towards the future, " Fitzpatrick said.

"We're using super-macro and robot camera techniques that we've only just recently developed," he said.

"It's a massive first time thing for the BBC to actually outsource it to an Australian production company."

It is expected a leading Australia actor will narrate the series, which will be seen by 200 million people.
