That figures. It's just that it's hard with actors to tell what they would really sound like if they weren't actors. 'The opposite of people' as Stoppard suggests in Rosencrantz and Guildenstern are Dead.
BTW - I wasn't accusing you of being posh, just wondering for some reason what the more fancypants Aussies that have sophisticated dinner parties and go to the opera sound like in the wild, and to what extent they try to sound 'not Australian'.
The UK has still made practically no progress in overcoming its class prejudices and assumptions, and I suppose it's one thing that we assume other English-speaking nations are better at - just being themselves (vocally) and not having to affect an accent that says 'I've made it, I'm superior'. The contrast between adopted Brit Maxwell, and grittily Australian Murdoch, in a way.
