Acting for me was hard enough without having to think of the accent. And also, when I was auditioning for stuff I would walk into the room with an Australian accent, and I would do the audition in an American accent, and they would invariably say, 'Yeah, it's that good, but I can still hear the oddity coming through.'

As an actor, you want new challenges. U.S. TV can be very formulaic. So when something gets a reaction, as 'The Slap' has, that's great. The sense I get is that it's not about me or my performance. More than anything it's the subject matter that people are focused on.'

I think it's unreasonable to expect kids at 17 to know what they want to do with the rest of their lives. And actually, I guess I had a desire to be an artist, and I did enroll in art school out of high school.

I thought I was clever by greeting casting agents in my Australian accent and then switching to an American one during the performance. But the Australian accent seemed to put them off. Now it's the opposite; they love Australians. And with my thick Californian accent I now have a problem convincing them I'm Australian.
