Most experts believe the accent - known for its flat tone, Nasality and elision of syllables - developed from the mix of dialects found in the early colony. Various myths have arisen to explain certain features of the Australian drawl, including the claim that Australians mumble to avoid swallowing flies.
Linguists from Macquarie University in Sydney said the accent would have developed very rapidly as a means of demonstrating "peer solidarity" among the children of the new colony.
"Even when new settlers arrived, this new dialect of the children would have been strong enough to deflect the influence of new children," they said.
But the latest theory, suggesting that the colony's heavy drinking played a role, and Mr Frenkel's appeal for clearer speech, appear to have largely been well received in Australia. "Dean Frenkel is right about the need for better speaking skills," said Anne Riddell in a letter to The Age. "And it's not just about pronunciation; vocal quality or timbre matters, as does intonation - the way the pitch of the voice rises and falls."
The accent has long proven divisive, with Winston Churchill calling it "the most brutal maltreatment which has ever been inflicted upon the mother tongue".
By contrast, Mark Twain apparently expressed a fondness for the tendency to abbreviate words and drop syllables, saying the accent was soft and had "a delicate whispery and vanishing cadence which charms the ear".
