Jan says she's actually sick to death of being mistaken for Australian ( she's been in the US 5 years now). It's fairly evident that most Americans really can't tell English accents apart. The interesting thing is that her accent is not even close to Cockney. I can confirm as an American that to me Cockney and Australian do sound fairly similar. She can't understand why I can't tell the difference easily. I would bet that it boils down to the English accents most Americans would have heard--primarily in the movies---and that's Cockney and BBC/ Queen's English. So for Americans, if it's not one, it's likely the other--that's what most Americans would guess.
