His most brutal moment probably came in 1962, when he was sent by his father, with a few mates, to rough up the owner of a Sydney publishing house who was refusing to sell. He was busy trashing the office when Rupert Murdoch, also with a few mates, turned up to fight him. Almost as good as cricket, Packer-style.
Does anyone else remember that scene in the Simpsons when Murdoch sends his thugs to beat up Homer? The Simpsons got it right again.
