After three minutes of studying the pictures, Australian video referee Stuart Dickinson ruled that Mark Cueto's foot had brushed the touchline and therefore gone out of play before he grounded the ball in the 42nd minute.
That turned him into public enemy number one in the eyes of England supporters, even though most rugby analysts believe he made the correct call.
But at home, he is a hero. Fuelled by the intense sporting rivalry between the two nations and England's defeat of their country in the quarter-finals, Australian rugby fans have swamped online message boards and radio chat shows with messages of support for their compatriot.
Labelling Mr Dickinson "the best TV ref in the world", Australians are clearly delighted that he refused to allow the try.
Writing on the social networking site Facebook, Catherine Kiernan said: "Mr Dickinson has denied the try to England, allowing South Africa to win the Rugby World Cup. Woo Hoo! The English team are gutted hee hee."
"Obviously when we can't win, Pommy bashing is our number one sport," wrote Keith from New South Wales. "Let's face it, it was going to be the only thing we have shown any strengths in at this cup."
Scores of fans described Mr Dickinson as an "absolute legend". Their English counterparts were less complimentary.
"England were cheated out of the World Cup by an Australian," supporter Ken Ashby said on another internet forum.
"The world saw the same video footage as him and no one could, with any degree of integrity reach the same conclusion. The reputation of rugby will be forever tarnished." (Daily Mail)
