I’ve always considered the Australian accent to be fairly homogeneous across regions, but certainly there isn’t the extreme diversity that the UK and America have. How much diversity is there, and what are the various characteristics? How long would it take you to tell a Cockroach from a Cane Toad when you meet him in the street?
I’m not expert, but i assume it’s the same as anywhere else.
I live in Quebec, a cousin of mine goes to a French school in Montreal. She struggles understand my Grandmother when she speaks French, and she only lives 2hrs away in the country.
In theory the accent should be the same, but it’s not. It’s just different enough.
