As a refreshing change from the polished, homogenized so-as not-to-offend Anyone (and piss off legions) - smarmy uniform voice-inflections of our infamous Talking Heads (Corp Tee Vee, Govmint or Pundit).
Funny thing tho - Brit-speak, especially the Royals' highly-refined skewed vowels and such -- seem about as grating, for being so obviously a product of the Class madness from all that History. Dunno about Oz and environs: are there remaining echoes of (intentional) Class-speak -- such as determine one's fate in your own Corporate orthodoxy?
(My guess.. would be - that the origins of your locals, bein er anti-Authoritarian! - to say the least - might have attenuated this preposterous habit of evaluating individuals on the basis of voice-nuances. Is that Pollyannish of me?)
