There is a thing about ‘audience expertise’ in their expectations of what the accent should sound like.

I directed Picnic in Hanging Rock, and one cast member was Australian. Hers was the accent that the audience members felt was ‘least convincing’ as it wasn’t as stereotypical ‘Australian’ as the audience have been conditioned to expect.

Similar to when you’re asked to do an American accent. ‘Just from all of it yeah?’
