Prof Geoffrey Blainey said one of the biggest changes over the past 50 years was the astonishing improvement in pronunciation and grammar.
"That clearly has come from television and radio and films, not from what's been taught in schools," he told the Herald Sun.
Prof Blainey said earlier generations used to say things like "them days" and "all of youses".
"I'm not criticising them, that's what they learned in childhood, but that old grammar has virtually vanished," he said. "Even when you listen to the footballers today, they all speak well."
