I have trouble talking to fishermen all the time. Everyone has trouble understanding me down here, I get asked if I'm a kiwi, Irish, Scottish or from Tasmania, nobody ever picks it right that I'm an Essex boy! I did get asked if I was a Kiwi when I worked in Oxford too. Even using the radio at work can be a nightmare, with the police security people never understanding what I say. Our youngest is 6 and she's a proper aussie girl though, but the SA accent is about as English as you'll get here.
