Video footage of Steve Irwin's last moments shows the popular crocodile wrangler pulling out the stingray barb which ended his life, according to Irwin's producer.
John Stainton, producer and director on many of Irwin's projects, described the video as the worst thing he had ever seen.
"I have seen the footage and it's shocking," Mr Stainton told reporters in Cairns. "It's a very hard thing to watch because you're watching somebody die and it's terrible."
Mr Stainton, said the footage showed Irwin whipping the barb out of his chest before losing consciousness.
"It shows that Steve came over the top of the ray and the tail came up, and spiked him here [in the chest], and he pulled it out and the next minute he's gone." "That was it. The cameraman had to shut down."
