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 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.

In primary school I was terrible. I don't think I was particularly well behaved in high school, but I started to apply myself.

One culture I find fascinating to juxtapose against American culture is the culture of Germany. They've gone through a long process through their art, poetry, public discourse, their politics, of owning the fact of their complicity in what happened in World War II. It's still a topic of everyday conversation in Germany.

I wrote as a kid, but I never wanted to be a writer, particularly. I had been drawing and painting for years and loved that.

Whether it be personal or musical, I just think I'm a walking art piece, just a ball of creativity.

The art of songwriting is just stumbling your way to something really special, and you don't know what you're going to write until you are writing it. There is no formula. And, sometimes, you really have to work at it and hunker down.
