Interesting premise. Certainly left me curious.
I am having a really hard time imagining Lois Lane with an Aussie accent. The image your writing has left me with is that her accent is a strong bush one (as if from somewhere out Lightning Ridge way). I've not known Melbournian's to have such strong accents (normally you have to live a little rural... or in Queensland *ducks*) but maybe seeing so much colloquial terminology is skewing my perception. Either way, great education lesson for the yanks and POMS out there on how people 'down under' speak a language of their own.
I am sure Clark will however make the correct choice and support the Sydney Swans.
Failing that, he needs to change codes and follow Union instead.
