Ms Ingelton, who travelled extensively with Dr Fabricius in making the documentary, expressed her admiration for the scientist.

"This is a contentious subject and (in the film) farmers expressed their desire to see the science to back up claims of the effects of land use on the reef," Ms Ingelton said. "Katharina was conscious of the need to communicate the science so it could be understood. We took up an enormous amount of her time and she was very patient. "I hope two points come across in the documentary. Firstly, that scientists’ work is painstaking and, secondly, that some farmers are introducing innovative land use practices to prevent run-off. "

Dr Fabricius’ team, supported by the CRC Reef Research Centre, is concluding a three-year study on the effects of run-off. She said the documentary successfully addresses both the scientific process and the human dilemma.

"Our research shows that recruitment rates of coral are low, and algal cover is high, in areas exposed to flood plumes that discharge more sediment and nutrients than in pre-European times," Dr Fabricius said. "The film highlights the need for joint solutions to move forward and the fact that farmers are concerned and need help to make the necessary changes. I would encourage all residents of North Queensland to see the film."

The film has been sold in France, Ireland and China. It is being shown nationally on SBS Television on May 20 at 8.30 p.m.
