Conservationists are anticipating a victory in their long running battle with farmers over the effects of runoffs from pesticides and fertilisers on the Great Barrier Reef.

But farmers say there’s no proven links to coral bleaching and infestations of the crown of thorns starfish, and it’s just part of Green preference deals.
